Connections for your best high-def video sources
The 'SR876 boasts some of the most extensive video capabilities you can find in a home theater receiver today. Four 1080p-compatible HDMI inputs offer plenty of switching flexibility for your high-def gear, while maintaining pristine digital signal quality. Two HDMI outputs offer great convenience to anyone with two HDTVs, or an HDTV and a high-def projector.

Advanced 1080p video upconversion
Onkyo also outfitted this receiver with the acclaimed Silicon Optix Reon-VX HQV™ video processing chip. This sophisticated technology provides cutting-edge video scaling and deinterlacing capabilities — including digital upconversion of all your video sources to an HDMI signal with up to 1080p resolution. You'll see smoother, more detailed picture quality from your video gear, and enjoy the convenience of a single-cable connection to your TV.

Precision auto setup tailors sound to your room
The 'SR876 includes Audyssey MultEQ® XT, an automatic speaker calibration system that helps you get the most accurate home theater sound possible. The receiver uses the supplied microphone to analyze sound from up to eight different listening positions, then automatically adjusts level, equalization, and delay settings for each speaker. You get precise response across a wide listening area instead of just a single "sweet spot," so everyone in the room can enjoy optimized home theater sound.

Multi-room audio/video
The 'SR876's three-room/three-source output offers especially flexible listening and viewing options for the whole family. You can watch the game in the living room while your kids enjoy a movie in the den, and your wife listens to stereo music on the radio out on the deck.

Onkyo TX-SR876

John from Southgate, Mi. on 12/2/2011

Bought this unit Dec. 08 had it about 2 months before I had to take it to a service center near me (thank God),since then it has been back four times the last was in Apr. 2011. Brought it home still didn't work right. Can't seem to get the HDMI working correctly. I give up no more ONkyo's for me.

Pros: Good when working

Cons: Too much money for this piece of junk, no wonder they quit making this unit.

Worked for a year

Jason C from Atlanta Ga. on 11/24/2010

Crutchfield Customer Review (What's this?)

It worked great for a year. Took it in for warranty and no video at all. Lot of money to spend for a one year throw away receiver . Should have got cheapest thing they had. Crutchfield was great, can't fault them.



HDMI problems

skye from Rochester, MN on 9/23/2009

Crutchfield Customer Review (What's this?)

Purchased this in December 08 and had high hopes based on previous reviews. First thing I noticed was how heavy it was, the second was how warm it runs...this sucker gets HOT. Setup was easy/intuitive I thought, especially with the microphone. After initial setup, was a little disappointed in the volume. I like to listen to my movies and my music loud, but I still want clarity. The sound was great but I had to severely crank up the volume to get what I wanted. I decided to push it and at 0 db it cut out and went into a protection mode. The volume definitely depends on the content however, as it seems the source (my HD DVR streaming XM radio) was much quieter than the Blue Ray movies I played through it. My BIGGEST complaint is that, after only owning the receiver for 8 months, the HDMI inputs seem to have stopped working. Was told to ship it in to an authorized Onkyo repair shop and Onkyo customer support was VERY RUDE. Thumbs down for Onkyo support. Only wish they were as awesome as Crutchfield support. I will not be purchasing another Onkyo after this.



Much better the second time around.

Eddie from Daytona Beach, FL on 9/5/2009

Crutchfield Customer Review (What's this?)

Purchased a TX-SR806 and it was great until turning it on the next morning only to find static from all the speakers until the unit warmed up. Called Onkyo tech and after trouble shooting was told "The unit is defective, send it back" Decided to upgrade to the TX-SR876 after reading about the "Blue spot" problems with the 806. The 876 is great. It replaced a 15 year old receiver. I'm running a 7.1 Polk system and through this receiver they sound GREAT! Every source I've run through it, Blu-Ray, DVD, CD's, FM, and DirectTV HD works fine. Video through HDMI is unbelievable. Set up with the Audyssey mic is really easy. Crutchfield was great, sending the replacement unit out the next day, before I had returned the old unit, and only charging me the difference in price.

Onkyo TX-SR876

Jared from Anchorage on 3/10/2009

Crutchfield Customer Review (What's this?)

Very solid, easy to use and setup receiver. Sound is flat out amazing. Receivers in this power class create heat and need space. I will admit that the Reon chip at the back left corner gets warm, but nothing I find out of the norm. The video up-conversion is fantastic as well. Great interface, that is simple and easy to navigate.



Worth every penny

Matt from Rancho Cucamonga, CA on 2/5/2009

Crutchfield Customer Review (What's this?)

I was in the market for a replacement to my old unit that only lasted a few years and kept coming back to the Onkyo line for the features. It also helped that my very first receiver was an Onkyo that is still being used by another family member to this day. First Impressions: Excellent, everything in it's place. Clear instructions and a thorough manual. No damages, and a beautiful receiver. Installation/Setup: Installation was a breeze, but be warned this unit is HEAVY. The on screen menus are awesome Onkyo clearly spent some time on the user interface. Other companies should take note of this (eg. Denon, Sony). The Audyssey self set-up is awesome, it made the room configuration that much easier. Only minor tweaks were needed afterwards (mainly a difference in preferences) Extended use: In a word, "perfect". Clear sound quality, excellent picture quality for the HDMI switching, and a solid build. If you are in the market, I highly recommed this unit.



Heat your home with this......

George from Ft. Lauderdale on 2/4/2009

Crutchfield Customer Review (What's this?)

Unit runs very hot, sound was Ok, but not overpowering like I would expect for 140 watts/channel, did recheck polarity of speakers.(Running a 5.1 system). remote was somewhat difficult to use. Finally the video processer seemed to quit and Tv screen went light tan in color. Attempts to reset were frivolous. Unit needs plenty of space for ventilation. Built in malaysia, can you say quality control issues??? Great price for the specs. Somehow wary of products at a great price and will pay more for Denon quality next.



A Must Buy

Charles from Bremen, Georgia on 1/25/2009

Crutchfield Customer Review (What's this?)

Bought this receiver to replace an older model Onkyo that was hooked up to a 7.1 system. I never realized how good my speakers really were until I hooked up the 876! Set up was a snap, setting up the speakers was the easiest I have ever encountered. If you are looking for a good system and an even better price, I would highly suggest the TX-SR876 along with purchasing from Crutchfield. They were more than helpful over the phone. Unit arrived as promised and the results exceeded expectations. I would buy Onkyo again and from Crutchfields again also.



Sonic and Visual Perfection

Jason from San Diego on 1/25/2009

Crutchfield Customer Review (What's this?)

I replaced a Denon AVR 3803 with this unit, and I am delighted. The Audyssey set-up is stellar. I hired an ISF calibrator to calibrate my new plasma TV, and figured I would have him calibrate the AVR's audio. He normally charges $400 just for the audio set-up, but told me that the Audyssey system is so advanced that he would charge me only $99, as he never has to add much tweaking to the audio, after the Audyssey works its magic. (ADVICE-- even if you do not think that you will have more than a few people at a time, watching movies, etc., place the Audyssey set-up microphone in the maximum 8 positions-- in doing so, your unit will "get to know" your room that much better.) After my calibrator ran the Audyssey set-up, his advanced diagnostic tools concluded that only one additional manual adjustment was needed, one of -4dB at 1 khtz. (In general, be patient-- the set-up is time well spent.) After having enjoyed my Onkyo for a few weeks now, and having read dozens of articles online, I am convinced that this is the best AVR under $4000. As it costs well under that price, this is quite the find. This is a complex machine, and you cannot simply plug and play if you want to reap its myriad rewards. Study its manual ahead of time.




Patrick from Columbus, OH on 1/19/2009

Crutchfield Customer Review (What's this?)

Received my TX-SR876 at the end of November. Setup was no problem. Have it running an acoustimass w/ 5 channels, and an acoustimass w/ 2 channels for the rear. Feel like I'm in the movie! Various soundfields sound very good. Sounds awesome w/ videogames also. Video output to an RCA DLP w/ DVI. No problems w/ the dvi, unlike a previous sony receiver. Only minor irritation is the length of time it takes to calculate speaker calibration. Other than that, very pleased w/ my move from Sony to Onkyo.



One disappointment

Rich from Union City, NJ on 12/11/2008

Crutchfield Customer Review (What's this?)

Set up and use of this receiver were straight forward, including customizing the display for the various sources. The set menus were a little obtuse, and slow to respond. The one thing that does NOT make me happy was the discovery that the second and third zones will not feed digital sources?! So, for example, if you've run the second zone speakers to the kitchen so you can hear the radio, and it is tuned to an HD FM station, the second zone will only feed the analog signal, leaving you with a 1/2 second or more delay, plus static. TV audio coming through HDMI, or an HDMI connection to iTunes through an AppleTV, don't come through at all. Useless!



Onkyo TX-SR876

Fathi from Fayetteville, NY on 11/13/2008

Crutchfield Customer Review (What's this?)

Excellent sound and easy to operate. Setup was easy and it produced great sound while watching movies or sports.



Fantastic A/V Receiver!

Jim from Thorne Bay, Alaska on 10/23/2008

Crutchfield Customer Review (What's this?)

I recently upgraded my Onkyo HT-790 (which was great) to the TX-SR876 and I must say I am IMPRESSED! The ease of setup, a great remote (runs everything), upconversion to 1080I and the 140 watts per channel make this receiver a powerful MUST for your home theater system. Even at low volumes my 7.1 surround system sounds terrific!! If you are looking to buy now, buy this one.



Onkyo TX-SR876

Robert from San Francisco, CA on 9/26/2008

Crutchfield Customer Review (What's this?)

I've always been impressed with Onkyo products, the TX-SR876 is no exception. It worked exactly as expected, setup and calibration was flawless. Quality of the upconversion is the best I've seen in this price bracket, certainly better than Denon or Sony. If you plan to use a Harmony remote you can save yourself some time by selecting the TX-SR875 as they don't seem to know about the 876 yet.

Input and Output Notes


7.1 Channel Amplifier: The Onkyo TX-SR876 features a 140 watt x 7-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.

Digital-to-Analog Converters (DACs): To decode and playback high-resolution recordings, this receiver is equipped with Burr-Brown 192kHz/24-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. Previously only found on Onkyo's high-end components, 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).

Multi-Language On-Screen Display (OSD): An OSD can be displayed on your television for easy system setup. The joystick/enter button on the remote makes 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 select a 4:3 or 16:9 aspect ratio for the monitor output so the menu is displayed properly to match your TV's screen. You can choose from several languages for the receiver's on-screen display menu: English, German, French, Spanish, Italian, Dutch, Swedish, or Japanese.

Component Video Switching: In addition to composite and S-Video switching, this unit can switch between high resolution component video sources. There are 3 component video inputs, each of which can be assigned to the DVD, VCR/DVR, CBL/SAT, GAME/TV, AUX 1, or AUX 2 input, and 1 component video monitor output. The component video inputs and outputs have a bandwidth of 5 Hz to 100MHz.

HDMI Switching: The TX-SR876 has four HDMI version 1.3 inputs and one HDMI version 1.3 output for connecting DVD players, HDTV set-top boxes, and other video components through the receiver to your TV or projector. The HDMI cables will pass digital audio and video. The HDMI inputs 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 can accept 480i, 480p, 720p, 1080i, and 1080p signals. The HDMI output can be scaled; resolution can be set to Through (no scaling), Auto (resolutions not supported by the display are automatically converted), 480p, 720p, 1080i, 1080p, or Source (resolution set for each source individually). Each of the HDMI inputs can be assigned to any of the six A/V inputs (DVD, VCR/DVR, CBL/SAT, GAME/TV, AUX 1, or AUX 2).

Video Upconversion and Scaling: The Onkyo TX-SR876 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 deinterlacing, 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-SR876 will upconvert 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. Incoming video signals can also be scaled, up to 1080p. The receiver can also convert composite video and S-video signal to component if your television does not feature an HDMI input.

RIHD (Remote Interactivity Over HDMI): RIHD synchronizes RIHD-compatible displays and components for integrated control via HDMI connection and use of the receiver's IR remote control. RIHD provides the following integrated operations:

  • Control: this function allows CEC-standard-compatible equipment connected to HDMI and RIHD-compatible equipment to be operated together with the Onkyo receiver
  • Power Control: provides an electrical power link between the TX-SR876 and RIHD-compatible components through the HDMI connection and allows for those components to turn on or off with the receiver
  • TV Control: allows you to control the TX-SR876 from an RIHD-compatible TV that is connected via HDMI, currently compatible with Panasonic Televisions featuring EZ Sync

Built-In HD Radio: In addition the analog AM/FM tuner, the Onkyo TX-SR876 features a built-in HD AM/FM tuner. HD Radio technology brings digital radio to conventional analog AM and FM radio stations with improved sound quality, better reception, and new data services. HD Radio technology provides CD-quality sound for FM stations and FM-quality sound for AM stations. In addition, FM HD Radio stations can transmit multiple programs on the same frequency by using multicast channels. HD Radio also features text data display which includes station name, song title and artist name. HD Radio stations broadcast on the same AM and FM frequencies they've always used and you can receive them by tuning into your favorite station as normal. You can store them a presets just like standard AM and FM stations. If a tuned AM or FM station supports HD Radio technology, the receiver's display HD indicator will light up.

Satellite Ready: The Onkyo TX-SR876 features proprietary ports on the rear panel for XM and Sirius Satellite Radio connection. In addition to the following optional satellite tuners needed (sold separately), you will need a subscription to XM and/or Sirius Satellite radio.

  • XM Satellite Radio Ready: The receiver can be connected to the optional XM Home Mini-Tuner and Home Dock (item number 700XMTUNPK, sold separately), allowing you to receive XM Satellite Radio through the TX-SR876. You can search XM radio stations by Channel, Category or Direct Tuning. You can also choose to display the following XM information on the receiver's display - Channel Name, Channel Number, Category Name, Artist Name or Song Title.
  • Sirius Satellite Radio Ready: The TX-SR876 can also be connected to the optional SiriusConnect Home Tuner kit (item number 607SCH1, 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.

iPod Compatible: The DS-A2X or DS-A3 Remote Interactive Dock for iPod (item number 580DSA2X and 580DSA3) provide an interface between an iPod digital media player and Onkyo TX-SR876. Once the iPod is docked you can control basic functions such as play, stop, and skip via the Onkyo system's RI-compatible wireless remote control. The dock also charges the battery in the iPod, and allows you to view digital photos and video on your home theater system (photo/video transfer not available with iPod classic, 3rd generation iPod nano, iPod touch, and iPhone).

Audyssey: This receiver is equipped with an Auto Setup and Room Equalization function, to achieve the most ideal sound field for your room. The Audyssey MultEQ XT 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 XT: MultEQ 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
  • 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 of the 7.1 channels is set individually from 0.5 to 30 feet in 1/2-foot increments.

Speaker Levels: You can manually adjust the level of each of the 7.1 channel outputs from -12dB and +12dB in 0.5dB increments; -15dB to +12dB for the subwoofer.

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-SR876 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, 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. The center and surround 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 the Front, Center, Surround, and Surround Back speakers; 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 subwoofer is 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-SR876 offers the following THX surround modes:

  • Neural THX 5.1/7.1: Neural-THX Surround employs psychoacoustic frequency domain processing, which delivers a more detailed sound stage, superior channel separation, and localization of audio elements; Neural THX 5.1 and Neural THX 7.1 modes can expand any 2-channel stereo source for 5.1/7.1-channel playback; 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

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

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 theaters may sound too bright when played back through speakers in the home environment. This can be set to either On or Off.

Bass and Treble: You can adjust the bass and treble separately for the front, center, surround, and surround back speakers. Bass is also adjustable for the sub output. You can boost or cut low-frequency (20Hz) bass output from -10 to +10 dB in 1 dB steps. You can boost or cut high-frequency (20kHz) treble output from -10 to +10 dB in 1 dB steps.

Late Night Feature: The Late Night feature limits the dynamic range of Dolby Digital recordings. Limiting the dynamic range makes it 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.

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.

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 readjusting 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:

  • Maximum Volume: prevent the volume from being turned too high by setting independent maximum levels for the main zone, Zone 2 and Zone 3
  • Power On Volume: independently specify the turned-on volume for each zone; specify any volume or Last (the same level that was used when the receiver was turned off)
  • Headphones Level: set the headphone volume relative to the main volume, choose a level between -12dB and +12dB

Name Edit: You can enter a custom name for each individual input selector and radio preset for easy identification.

Amplifier Assign: There are seven amplifier channels built into the receiver. These channels are typically used for 7.1 channel surround in the main room (with the surround back terminals assigned the the surround back speakers), but the amplifier assign function gives you the option of configuring the system differently if you prefer (limiting the main room to 5.1-channel operation):

  • Bi-Amp Connections: Some loudspeakers are equipped with two sets of input terminals for bi-amplification; you can assign the surround back terminals to provide power to bi-amp the front speakers.
  • Bridging: Two sets of amplifier channels can be bridged, almost doubling the power output to the front speakers. When bridging the amp, use speakers with 8Ω or higher impedance.
  • Multi-Zone Operation: Two amplifier channels can be assigned to power stereo speakers in Zone 2.

Multi-room Capability: You can use three speaker systems with the TX-SR876 receiver, a surround-sound speaker system up to 7.1 channels in your main listening room (Zone 1), an audio/video stereo speaker system in a second room (Zone 2) and an audio only stereo speaker system in a third room (Zone 3). The zone 2 and 3 outputs allow you to enjoy one source in your main listening room, while other sources play in remote rooms. Depending on how you configure the receiver, using Zone 2 will require an additional monitor, amplifier and speakers, a set of powered speakers, or simply a set of non-powered speakers located in a remote location. You can connect the dedicated Zone 2 stereo AV RCA line outputs to a receiver/amplifier or powered speakers along with a monitor in the second room while powering a 7.1-channel speaker system in the main room; the output level of the RCA line outs for Zone 2 and Zone 3 can be fixed or variable, so they can be connected to an amplifier or powered speakers equipped with or without a volume control. You can also connect a pair of speakers to the receiver's dedicated Zone 2 speaker terminals and simultaneously power a 5.1-channel speaker system in the main room. When the Zone 2 speaker terminals are turned on, the Surround Back speaker outputs do not work. When the Zone 2 speaker terminals are off, the Surround Back speaker outputs work as normal. The Zone 2 speaker output volume setting can be controlled with the remote. Only analog sources can be played in Zone 2 and Zone 3. Zone 3 requires an additional amplifier and speakers or a set of powered speakers to listen to a different 2-channel stereo source in another room while still playing 2-channel audio in Zone 2 and multi-channel audio in your main room (Zone 3 does not offer speaker terminal connection).

ISF Mode: The receiver has been designed to incorporate setup and calibration standards established by the Imaging Science Foundation (ISF). The ISF has developed carefully crafted, 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.

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

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.

Lock Setup: With this feature, you can protect your settings by locking the setup menus.

Remote Control

Multi-brand/Learning Remote with Joy Stick Button: The supplied wireless remote is a multi-brand/learning remote. The remote is pre-programmed to operate Onkyo components. In addition, the remote is pre-programmed to operate other popular brands of equipment, including DVD players and recorders, CD players and recorders, TVs, VCRs, cable boxes, MD recorders/players, and satellite receivers. Also, the remote can learn up to 90 commands from infrared remotes of other components. A joystick button simplifies menu navigation and doubles as an enter button.

Macros: Three macros can be programmed to perform a sequence of actions with just one button press. Each macro button can perform up to 8 commands.
