Now add nine channels of brawn
Yes, you could set up a nine— speaker home theater with two powered subs and force the neighbors to move far, far away. But the 'NR5008 can do more than just volume. It also provides sonic precision and flexibility. If you have a 5.1 system you can dedicate two of the receiver's unused channels to bi-amplify your right and left main speakers (provided they're compatible). Another two channels can be used to create front "height" speakers for an added sense of dimension with Dolby Pro Logic® IIz. Or you could use two powered channels to bring music to one or more rooms in your home. The choice is yours.

Link globally, attach locally
The 'NR5008's built-in vTuner lets you listen to Internet radio stations from around the world or around the block. You can also plug in your iPod® and iPhone® directly through the front panel USB, eliminating the clutter and expense of an add-on dock. Hear thousands of songs with a thumb drive or other memory device. And connecting to your home computer for sound file access is made easy with this DLNA certified receiver. When you run a network cable from this receiver to your home network, you can stream music, photos and video stored on your computer.

Cutting edge and user-friendly
Setting up and controlling a receiver with so much performance and capabilities can be a hassle, but not with the 'NR5008. Its multibrand learning remote gives you total control via a really well-designed menu right on your TV screen for easy navigation through a transparent image. Plus the receiver is loaded with the Audyssey MultEQ® XT32,a more powerful version of their acclaimed speaker calibration system that delivers meticulously accurate, room-specific sound at the touch of a button.

    China made HDMI PORT?

    Jeff from Florida on 2/26/2015

    Crutchfield Customer Review (What's this?)

    I had the TX-NR5008 and the HDMI OUT1 port failed. They could not get parts after I had to ship it to New Jersey so they replaced it with the 5009. Less than one year later another HDMI OUT 1 port failure. Now they say the warranty on the 5009 is Not two years and it is not covered.

    Pros: Two HDMI out ports

    Cons: Poor quality HDMI ports used in the manufacturing process.

    Great Receiver when it isn't in the repair shop

    DonU from Oxford, MI on 12/24/2013

    Crutchfield Customer Review (What's this?)

    Great features at a premium price, but cheaper than other brands for what you get. I was able to start with my 5.1 speaker configuration and grow to a 7.2 and then to a 9.2 and this receiver delivers loads of power to all channels. My only gripe was the loud relay switch Onkyo opted for the makes a very noticeable CLICK whenever the sound format changed from Stereo to surround sound often found on network TV when commercials come up. In a typical commercial break you hear it 3-5 times. I found that after a short stint of thundering bass and great surround sound in my movies at home it just stopped working. It would power up, but it would just flip through every input source and nothing I pushed would make it stop. This was 7 months after purchasing the unit here at Crutchfield. I called support and they directed me to Onkyo Repairs. I had to drive it to a repair center as the shipping cost for this monster was crazy. It took 2 weeks and I was back in business. I am now beyond my 2 year warranty by 10 months and guess what? It is broken AGAIN, but this time it simply lost audio on every source. That relay click that I mentioned above? I don't hear it now so it must be 'stuck'. Now I REALLY don't like that decision by Onkyo. One can only hope the cost to repair it is not very high. I don't think I will be buying another Onkyo.

    Pros: - Great feature set for the money, best in class at price. - Flexible Zones for driving the patio speakers apart from the surround sound movie in the home theater at the same time. - Great on screen menus for easy setup - Audessy makes initial setup very easy, but I had to tweak it as most people would to suit their own ears. - HD Radio tuner (an optional accessory) is very nice and provides great clarity with Track, Artist and other information on the display

    Cons: - Relay that handles audio format decoder routing is very loud and clicks whenever audio format changes - Reliability is POOR. I have had 2 repairs done in less than 3 years. My $300 Sony did better... that is inexcusable at this price point. This is their BEST receiver and it is not reliable? The repair shop commented that it is a very common problem on these units. Ugh... an expensive mistake for me buying this unit. - She runs HOT. Enclosed cabinets WILL need cooling fans

    Crutchfield Customer Review (What's this?)

    I have the TX-NR5008 but this pertains to the models I have listed in the title. First, this is a nce unit, doing everything you can imagine and doing it well. You get a lot of bang for the buck, especially since they have a newer flagship model. When I bought the 5008, it was the flagship. Rather than going into all the good, there is something important to be aware of. After exactly two years of ownership, my reciever lost all audio. Searching the net, I found that this is something that is not unusual. It seems the HDMI board goes bad. I have no idea what the trouble is or if Onkyo has built the replacement to higher standards. I have also heard of multiple failures. If you consider this unit, or its kin, I would suggest you consider an extended warranty. I am in the process if having mine repaired as I write this. In the interim, I have bought an inexpensive reciever to use. I am already missing the sound quality of the Onkyo unit. The Onkyo processes just about anything you throw at it. You get a lot of bang for the buck. Just get an extended warranty if you can.

    Pros: Too many to list.

    Cons: Known issue with HDMI board failure

    I purchased this for my husband who has been so supportive of the family. He has been waiting years for an upscale system and this was part of it. This receiver has changed our audio experience. I also purchased him the Kef T Series Surround Sound speakers....what more can I say. Music, audio is fabulous. Now we need the Blue Ray DVD player. Thanks for the great service Crutchfield.

    Mixed bag

    BearZZ from Columbia, MD on 1/18/2011

    Crutchfield Customer Review (What's this?)

    The good: Great manual, user design, remote. Plenty of power (running Bridged) and flexible configurations; Audyssey Multi-32 XT EQ; looks nice. The bad: Corrupts component video signals even with all processing disabled; 'direct' sound lacks body (listening on B&W 801s). Bought this to upgrade from a 2002-model Denon 2802 (90W). The Denon had a warmer, more full bodied sound in its 'Direct' (no equalization) configuration. The Onkyo sounds somewhat lifeless in that configuration, so I run it with the Audyssey equalization and loudness compensation. It handles decoding of the Blu-Ray high quality audio modes seamlessly (I run both HDMI and component from my Samsung 6900 since the TV is component). The 'Home' button overlays an on-screen menu to control settings, but this feature is not available if you have the video processing bypassed. I have to bypass processing because even in the 'through' case, the processing adds a swimming Moire pattern faint but visible on 1080i sources and adds two single pixel vertical red lines near the right of the screen. Crutchfield sent me a second unit and it did exactly the same thing. Even with all video processing disabled, the 'pass-through' shifts the signal such that I had to adjust the vertical position and size in the television's service menu. I kept one of the units even with this problem because it looked like the equivalent Denon had its own issues.




    BobT from Toms River, NJ on 12/23/2010

    I've used Yamaha exclusively for years. When I came into the market again, I of course looked at Yamaha. Then I saw the onkyo. I went to my local home theater store, where I'd purchased before, & got a chance to see & hear this monster. I purchased this unit from Crutchfield for two reasons. I got lied to by the other guy & Dolly at Crutchfield not only knew her stuff, she also understood immediately my concerns about going away from Yamaha. This receiver is everything they say it is. The power is clean & there's plenty of it. The on- screen menus are easy to navigate. the setup functions actually work. The video upscale is the best I've seen. The automatic speaker setup, calibration & EQ actually worked. A friend of mine came over with his toys to check such things told me so. I put on Avatar & got blown out of my seat. This Receiver handles music just as well. The onkyo handles all formats & doesn't break a sweat. You can talk technology sure, but what really matters is what happens when you sit down & hit play. This receiver creates magic.

    charlesG from north collins ny on 11/29/2010

    Crutchfield Customer Review (What's this?)

    i have had this receiver about 90 days and so far it has functioned well. i run the amp at 4 ohm setting because my fronts are phasetech pc 9.1. i play at loud vol and the receiver does not cut out. the yamaha rx-3000 i had before this would shut off at high vol settings plus the fm sensitivity was poor. the onkyo got 6 fm stations compared to 1 for the other amp with the samr antenna. i have not scratched the surface of the onkyo features but all has went well. i love the onscreen set up feature which is a great feature. no more viewing a small led screen when doing system setup!

    Audio Features

    Amplifier: The Onkyo TX-NR5008 features a 145 watt x 9-channel amplifier (measured with two channels driven) into 8-ohms at 20 to 20,000 Hz with a maximum total harmonic distortion of 0.05%.

    WRAT (Wide Range Amplifier Technology): This technology uses low-negative-feedback circuit topology for accurate signal reproduction, improved dynamic signal-to-noise ratio, and better delivery of power peaks.

    Power Supply: The Onkyo TX-NR5008 features a Toroidal transformer and independent power supplies for the amplifier, the video circuitry, and audio circuitry.

    Amplifier Assign: There are nine amplifier channels built into the receiver; the nine channels can be assigned to power numerous speaker combinations, both stereo and surround sound. The terminals are labeled front L/R, surround back/zone3 L/R, front wide/zone2 L/R, front high L/R, surround L/R, and center. Additionally a pair of B speakers can be powered, four channels can be used to bi-amp the A or B speakers, or four channels can be bridged to two and power the A or B speakers (minimum 8Ω impedance).

    B Speakers: Unlike most receivers, the A and B speaker outputs on the TX-NR5008 cannot be played at the same time. They are designed to connect two sets of speakers in the same room; for example the A speakers can be part of the 7.1-channel surround system used when watching movies, and the B speakers can be used for more critical music listening in stereo.

    Multi-room Capability: You can use speaker systems in three rooms with the TX-NR5008, a multi-channel audio/video system in your main listening room, a stereo audio/video system in a second room (Zone2), and an stereo audio only system in a third room (Zone3). The zone 2 and 3 outputs allow you to enjoy one source in your main listening room, while other sources play in remote rooms. Both Zone2 and Zone3 have line level outputs, Zone2 has a composite video output, and the receiver's amplifier channels can be assigned to power Zone2 and/or Zone3 speakers (limiting the number of powered channels available for the main room). The output level of the RCA line outputs for Zone2 and Zone3 can be fixed or variable, so they can be connected to an amplifier or powered speakers equipped with or without a volume control. When the Zone2 speakers are powered by the receiver, the front wide and front B speakers are unavailable; when the Zone3 speakers are powered by the receiver, surround back speakers are unavailable. Only analog sources can be played in Zone2 and Zone3 and only composite video sources are available in Zone2.

    ARC (Audio Return Channel): This feature allows audio to be sent from your compatible HDTV to your receiver through the same HDMI cable already being used to send audio and video to your HDTV. This eliminates the need for extra cables connected to your television. The ARC function is only available through the main HDMI monitor output.

    Digital-to-Analog Converters (DACs): To decode and playback high-resolution recordings, this receiver is equipped with Burr-Brown 192kHz/32-bit DACs for all channels.

    Vector Linear Shaping Circuitry (VLSC): Conventional D/A conversion methods reduce digital pulse noise at the conversion stage but can't remove it completely. VLSC (Vector Linear Shaping Circuitry) employs a unique D/A conversion circuit to overcome this problem. Data is converted between sampling points and these points are joined with analog vectors in real-time to produce a smooth output wave form. The result is a virtually noiseless, smooth analog signal based on the digital source to bring out even the most subtle of nuances in your music, movie soundtracks and even MP3s.

    Speaker Impedance: There is a menu adjustment for minimum speaker impedance; options are 6Ω (for speakers 6 to 16-ohms) and 4Ω (for speakers 4 or 5-ohms).

    Audyssey: This receiver is equipped with an automatic setup and room equalization function, to achieve the ideal sound field for your room. The Audyssey MultEQ XT32 function is designed to optimize the sound quality at each listening position in the room. The included microphone is used to measure test tones at each listening position. This measured data is then analyzed using a program to improve acoustic characteristics in the listening area. For best results multiple positions should be measured (up to 8), including a main position. The main position is given more weight in the calculations.

    Audyssey Settings:

    • MultEQ XT32: The MultEQ XT32 function automatically determines the number of speakers and optimizes the crossover points, output levels, delay times, and equalization of all speakers based on speaker frequency response, speaker location, and room acoustics measurements.
    • Dynamic EQ: Audio engineers mix music and movie soundtracks at reference levels much louder than typical home listening levels. At lower volumes the human ear perceives sound differently; voices change, bass dissipates, and the surround effect becomes less enveloping. Dynamic EQ adjusts the frequency response curve based on volume to maintain consistent bass output, octave-to-octave balance, and surround impact, resulting in rich sound at any volume.
    • Dynamic Volume: Dynamic Volume addresses the issue of commercials that are too loud and movie soundtracks with vast differences between soft and loud passages; the results are more intelligible dialogue, loud passages maintain impact, and soft whispers are clearly heard. When the volume level changes, Dynamic EQ also adjusts the frequency response to maintain sound quality.

    Speaker Distance: The distance from your listening position to each speaker can also be set manually; each channel is set individually from 0.5 to 30 feet in 1/2-foot increments (this includes left and right Front Wide channels, left and right Front High channels, and two discrete subwoofer settings).

    Speaker Levels: You can also manually adjust the level of each channel output from -12dB to +12dB in 0.5dB increments; -15dB to +12dB for the subwoofers.

    THX Loudness Plus: A consequence of turning the volume below Reference Level is that certain sound elements can be lost or perceived differently by the listener. THX Loudness Plus compensates for the tonal and spatial shifts that occur when the volume is reduced by intelligently adjusting ambient surround channel levels and frequency response. This enables users to experience the true impact of soundtracks regardless of the volume setting. THX Loudness Plus is automatically applied when listening in any THX listening mode.

    Dolby Volume: Dolby Volume is an intelligent volume control system that improves audio frequency response and corrects volume differences between sources or types of content.

    Half Mode: Dolby Volume can be set to apply bass and treble attenuation to the audio when the system gain exceeds reference level (very loud). This enables a more perceptually flat listening experience as human ears are more sensitive to bass and treble at higher levels.

    Double Bass: You can increase the bass output by activating the Double Bass function; this feeds both the LFE and left and right channel bass output to the subwoofer. Double Bass can be set only when the subwoofer is set to On and the front speakers are set to full range.

    Crossover: The TX-NR5008 has a built-in crossover for the speaker system that can be set manually. The crossover points are set separately for the front, center, surround, surround back, front wide, front high, and subwoofer channels. The sub crossover options are 80(THX), 90, 100, and 120 Hz. The other channels can be set to Full Range, 40, 50, 60, 70, 80 (THX), 90, 100, 120, 150, or 200 Hz. All but the main speakers can also be turned off.

    LFE Level: You can set the level of the LFE channel individually for Dolby Digital, DTS, multi-channel PCM, Dolby TrueHD, DTS-HD Master Audio, and DSD sources. The level can be set to -infinity, -20 dB, -10 dB or 0 dB.

    Equalizer: Using the receiver's built-in electronic 7-band equalizer you can manually adjust the tone of each channel; the bands are centered at 63, 160, 400, 1000, 2500, 6300 and 16000 Hz and are adjustable from -6 dB to +6 dB in 1 dB increments. The subwoofers are also adjustable from -6 dB to +6 dB in 1 dB increments at 25, 40, 63, 100, and 160 Hz.

    THX Ultra2 Plus Certified: THX surround technology was founded by George Lucas. THX utilizes stringent standards that ensure movies are reproduced in movie theaters and home theaters just as the director intended. The TX-NR5008 offers the following THX surround modes:

    • Neural THX: Neural Surround employs psychoacoustic frequency domain processing, which delivers a more detailed sound stage, superior channel separation, and localization of audio elements; Neural Surround can be combined with THX Cinema, Music, and Games to expand 2-channel sources to 5.1 or 7.1 channels; XM Satellite Radio uses Neural THX encoding on select channels for decoding to 5.1 or 7.1-channel for playback (XMHD)
    • THX Cinema: carefully optimizes the tonal and spatial characteristics of the soundtrack for reproduction in the smaller home-theater environment
    • THX Music: designed for use with music (typically mastered at higher levels than movie soundtracks), THX Loudness Plus also configured for music
    • THX Games: designed for spatially accurate playback of game audio (mixed for a smaller environment than movies)
    • THX Ultra2 Cinema: expands 5.1-channel sources for 7.1-channel playback by analyzing the composition of the surround source and optimizing the ambient and directional sounds to produce the surround back channel output
    • THX Ultra2 Music: expands 5.1-channel sources for 7.1-channel music playback
    • THX Ultra2 Games: expands 5.1-channel sources for 7.1-channel game audio playback
    • THX Surround EX: expands 5.1-channel sources for 6.1/7.1-channel playback, especially suited to Dolby Digital EX sources

    Stereo, Dolby and DTS Listening Modes: This receiver incorporates powerful and accurate 32-bit DSP processors and a wide variety of listening modes to bring you maximum enjoyment from your audio and video software. The listening modes include:

    • Pure Audio: the display and analog video circuitry are turned off, minimizing possible noise sources for high-fidelity reproduction
    • Direct: audio from the input source is output directly with minimal processing
    • Stereo: sound is output from the front left and right speakers and subwoofer
    • Mono: monaural sound is output from your choice of speaker combinations

    Dolby Pro Logic II & IIx Music Modes: While listening in the Dolby Pro Logic II or IIx Music format, there are three further enhancements you can adjust:

    • Panorama: broadens the front stereo image to the surround speakers to provide a wraparound effect, especially effective when there is limited output from the surround channels, panorama can be turned on/off in the menu
    • Dimension: allows you to move the sound field forward or backward
    • Center Width: allows you to adjust the width of the center channel

    PL IIz Height Gain: The gain applied to the Front High speakers (when using PL IIz) is adjustable; Low, Medium, or High

    Center Image: In the DTS Neo:6 Music mode, the Center Image feature adjusts the output of the left and right channels relative to the center channel, allowing you to make the center channel more or less dominant as needed. This improves the image of the center channel, especially when the listener is off-center.

    Re-Equalization Circuitry: Re-EQ (re-equalization) corrects a soundtrack with high frequency response that's too harsh, compensating for the fact that sound mixed for large, plush theaters may sound too bright when played back through speakers in the home environment. This can be turned On or Off.

    Bass and Treble: You can adjust the bass and treble separately for the front, center, surround, Zone2, and Zone3 speakers. Bass is also adjustable for the sub output. You can boost or cut low-frequency (50 Hz) bass output from -10 to +10 dB in 2 dB steps. You can boost or cut high-frequency (20kHz) treble output from -10 to +10 dB in 2 dB steps.

    Late Night Feature: The Late Night feature limits the dynamic range of Dolby Digital recordings, making easier to find a volume that ensures the quiet sounds are not too quiet and the loud sounds are not too loud for night time listening. This allows you to comfortably listen without the need to constantly adjust the volume to keep from waking family/neighbors. The choices are Off, Low, and High for Dolby Digital and Dolby Digital Plus sources; Auto, Off, and On for Dolby TrueHD sources.

    Note: This feature only works with Dolby Digital, Dolby Digital Plus, and Dolby TrueHD encoded software and the depth of the feature will vary based on the individual software package.

    IntelliVolume: The IntelliVolume setup function allows you set a volume correction value for each source, to prevent large jumps in volume when switching from one source to another. This feature eliminates the inconvenience of manually adjusting the volume control each time you switch from a source with a weak signal to a source with a strong signal and vice versa.

    Volume Setup: The receiver volume can be configured in the following ways:

    • Volume Display: how the volume is displayed can be set to Absolute (Min, 0.5 to 99.5, Max) or Relative (-infinity, -81.5 dB to +18 dB)
    • Muting Level: choose how much the volume is attenuated when muted; -infinity (no sound) or -50 dB to -10 dB in 10 dB steps
    • Maximum Volume: prevent the volume from accidentally being turned too high by setting a maximum level
    • Power On Volume: specify the volume when the receiver is turned on; choose Last (the same level that was used when the receiver was turned off), Minimum, or set any specific volume level (can't exceed the maximum volume set above)
    • Headphones Level: set the headphone volume relative to the main volume, choose a level between -12dB and +12dB

    Digital Inputs: The TX-NR5008 has six assignable rear panel digital audio inputs (3 optical/3 coaxial) allowing you to specify which input source is connected to which digital input jack. The front panel optical digital input is fixed as the Aux source.

    Multi-Channel Input: The receiver is equipped with one set of 8-channel RCA type inputs for use with an outboard 5.1 or 7.1 channel decoder; there are inputs for left front, right front, center, left surround, right surround, surround back left, surround back right, and subwoofer.

    Line Level Outputs: There are 15 pre-amp outputs for connection to external amplifiers; 9.2-channel surround sound (including left and right outputs for front wide or front high channels, plus two subwoofer outputs), Zone2 stereo, and Zone3 stereo.

    Speaker Terminals: There are binding post connectors for the left front, right front, center, left surround, right surround, left surround back/Zone3, right surround back/Zone3, left front wide/Zone2, right front wide/Zone2, left front high, and right front high speakers. The binding posts are not 5-way because a plastic collar prevents their use with spade lugs; they will accommodate dual banana plugs.

    Sleep Function: From the remote, you can set the unit to automatically turn off after a specific time; from 10 minutes to 90 minutes in 10-minute increments.

    Video Features

    On-Screen Display (OSD): An OSD can be displayed on your television for easy system setup. The cursor and enter buttons on the remote make display navigation and setting adjustment simple and convenient. The setup OSD is passed through all the monitor outputs (composite video, S-video, component video, and HDMI). You can choose from several languages for the receiver's on-screen display menu: English, German, French, Spanish, Italian, Dutch, Swedish, or Chinese.

    HDMI Switching: The TX-NR5008 has eight HDMI version 1.4a inputs (7 rear/1 front) and two HDMI version 1.4a outputs for connecting Blu-ray Disc players, HDTV set-top boxes, and other video components through the receiver to your TV or projector. Any of the rear panel input jacks can be assigned to the BD/DVD, VCR/DVR, CBL/SAT, Game, PC, Tape, TV/CD, Phono, or Port input (the front panel HDMI input is fixed as Aux). Both outputs can be active simultaneously and will pass digital audio and video. The HDMI ports are compatible with DVI, so TVs and other displays with a DVI input can be connected using an HDMI-to-DVI adapter cable, along with audio cables (if desired). The receiver uses HDCP (High-bandwidth Digital Content Protection), so only HDCP-compatible components can display the picture. The HDMI inputs accept 480i, 480p, 720p, 1080i, and 1080p signals and the analog video inputs (composite video, S-video, and component video) are converted to HDMI for transfer to the TV.

    Notes: The 2 HDMI outputs display the same video signal and can be used simultaneously.

    Video Conversion and Scaling: The HDMI output can be scaled to 480p, 720p, 1080i, 1080p, or 1080p/24; or the resolution can be set to Through (no scaling), Auto (resolutions not supported by the display are automatically converted), or Source (resolution set for each source individually). The TX-NR5008 utilizes HQV Reon-VX technology to convert interlaced video signals to progressive scan signals. The HQV Reon-VX chip supports standard definition and high definition de-interlacing, 1080p reconstruction of film sources, filtering of jaggies and artifacts, and the reduction of random, mosquito, and block (codec) noise. HQV Reon-VX also enables color region enhancement and the rendering of more than one billion colors. The Onkyo TX-NR5008 will convert incoming analog composite video, S-video and component video signals to HDMI so you can connect all your video sources through the receiver and then to your TV via a single HDMI cable. The receiver can also convert composite video and S-video signal to component if your television does not feature an HDMI input.

    Component Video Switching: In addition to composite and S-Video switching, this unit can switch between high resolution component video sources. There are three component video inputs (each of which can be assigned to the BD/DVD, VCR/DVR, CBL/SAT, Game, PC, Aux, Tape, TV/CD, Phono, or Port input) and one component video monitor output. The component video inputs and outputs have a bandwidth of 5 Hz to 100 MHz.

    3D-Compatible: The TX-NR5008's HDMI v.1.4a connections will accept 3D video from your 3D Blu-ray player and output the video signal in 3D to your 3D-ready HDTV.

    x.v.Color: The receiver supports x.v.Color, offering a wider color range than the current broadcast standard. For the x.v.Color feature to be useful, the entire video production chain must be compatible (camera-editing-format-player-display).

    Deep Color: The Onkyo receiver also supports Deep Color which allows increased color depth of video signals passing through HDMI. Without Deep Color, the number of colors expressed by 1 pixel is 24 bits (16,777,216 colors). Using Deep Color, the number of colors expressed by 1 pixel is 36 bits. Since the gradation of the depth of a color can be expressed more finely with more bits, continuous color changes can be more smoothly displayed. For the Deep Color feature to be useful, the entire video production chain must be compatible (camera-editing-format-player-display).

    Note: x.v.Color and Deep Color technology are supported only when the source, HDMI cable, media (original recording), and HDTV all support those features.

    Auto Lip Sync: The Lip Sync function can automatically synchronize HDMI audio and video that has gotten out of sync due to the complex digital video processing being performed. With HDMI Lip Sync, the audio delay required to synchronize the audio and video is calculated and applied automatically by the receiver.

    A/V Sync: When the picture is not perfectly synchronized with the sound, this receiver can delay the audio from 0-250ms, in 5ms increments.

    ISF Mode: The receiver has been designed to incorporate setup and calibration standards established by the Imaging Science Foundation (ISF). The ISF has developed industry-recognized standards for optimal video performance and has implemented a training program for technicians and installers to use these standards to obtain optimal picture quality from the receiver. Accordingly, Onkyo recommends that setup and calibration be performed by an ISF Certified installation technician.

    Name Edit: You can enter a custom name for each input (other than Tuner) and radio preset for easy identification; up to 10 characters.

    Lock Setup: This feature protects all the programmed settings by locking the setup menus.

    Display Dimmer: The display illumination includes the green alphanumeric display and a blue ring around the volume knob. You can dim the display as follows: Normal and Volume light on, Normal and Volume light off, Dim and Volume light off, and Dimmer and Volume light off.

    Tuner Functions

    AM/FM Tuner: With the built-in tuner you can enjoy AM and FM radio stations. You can store your favorite stations as presets for quick selection. You can store a combination of up to 40 of your favorite FM/AM radio stations as presets.

    HD Radio Ready: The Onkyo UP-HT1 HD Radio Module (item number 580UPHT1, sold separately) sends high-quality digital AM/FM audio via a single proprietary cable to the Onkyo receiver's Universal Port. The same cable powers the tuner unit, saving on cable clutter. The tuner features 40 presets for FM and AM stations. A rear-side Universal Port input gives you the option of daisy chaining a second compatible device, such as the UP-A1 Onkyo Dock for the iPod.

    Sirius Satellite Radio Ready: The TX-NR5008 can be connected to the optional SiriusConnect Home Tuner kit ( 607SCH1, sold separately) or SiriusConnect Home Tuner Receiver (220SCH2P, sold separately), which allows you to receive Sirius Satellite Radio through the receiver. You can search Sirius radio stations by Channel, Category or Direct Tuning. You can also choose to display the following Sirius information on the receiver's display - Channel Name, Channel Number, Category Name, Artist Name or Song Title. You can store a combination of 40 of your favorite Sirius, AM, and FM radio stations.

    USB/iPod Connectivity

    USB Ports: The receiver's front and rear USB inputs will play music files stored on hard disc drives (AC adapter recommended to supply power), flash drives, and MP3 players that fit the USB mass storage device class (iPods are not compatible with the rear USB port). USB devices formatted with the FAT16 or FAT32 files system are supported; each folder may contain up to 20,000 music files and folders may be nested up to 16 levels deep. If the storage device has been partitioned, each section is treaded as a separate device. MP3 players containing music files that are managed with special music software are not supported.
