To enjoy true 7.1ch Dolby Digital TrueHD and DTS-HD surround sound, the receiver must be connected to your Blu-ray player via HDMI.
THX: The TX-SR608 is THX Select2 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.
THX Loudness Plus: THX Loudness Plus is a volume control technology featured in THX Ultra2 Plus and THX Select2 Plus certified receivers. With THX Loudness Plus, home theater audiences can experience the rich details in a surround mix at any volume level. 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. The THX Loudness Plus feature is automatically applied when listening in any THX listening mode.
Dolby Pro Logic IIx Music Settings: While listening in the Dolby Pro Logic 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.
PLIIz Height Gain: The Height Gain Control in Dolby Pro Logic IIz enables you to select how much gain is applied to the front-height effect speakers. There are three settings - Low, Mid, and 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. Adjustment varies from 5 (nothing subtracted from the L/R channels) to 0 (L/R channel output is cut in half).
Onkyo Original DSP Modes: The Onkyo TX-SR608 features its own proprietary set of DSP (Digital Signal Processing) modes to bring your movies and music more to life:
|DSP Mode||Description||Input Source||Maximum Speaker Output|

|Theater Dimensional|| |
enjoy virtual surround sound even with only two or three speakers; works by controlling how sounds reach the listener's left and right ears
Listening Angle: While listening in the Theater Dimensional mode you can adjust the listening angle to either Wide (40°) or Narrow (20°).
Audyssey 2EQ Automatic Speaker Setup: With the supplied speaker setup microphone, Audyssey 2EQ determines the number of speakers connected, their optimum crossover frequencies, and their distances from the primary listening position, then adjusts each automatically. The room's acoustical properties are then measured and corrected over the listening area in both the frequency and time domain. There is a threaded insert on the bottom of the microphone so it can be mounted on a tripod for accurate listening position placement. Three listening position measurements are taken, one primary and two secondary, to optimize the surround effect for a broad area. If you prefer you can also setup your speaker system manually:
- Subwoofer: yes/no; is a sub connected
- Crossover: set the crossover point for each set of speakers (front, center, surround, surround back, front wide, and front high) individually; full bandwidth, 40 Hz, 50 Hz, 60 Hz, 70 Hz, 80 Hz (THX standard), 90 Hz, 100 Hz, 120 Hz, 150 Hz, or 200 Hz
- Speaker Distance: the from the listening position to each speaker can be set from 1 to 30 feet in 1-foot increments
- LFE Crossover: this subwoofer crossover is set separately from the other speakers; 80 Hz, 90 Hz, 100 Hz, or 120 Hz
- Speaker Levels: the output level of each speaker is adjustable +/-12dB; -15dB to +12dB for the subwoofer
Audyssey Dynamic EQ: Audyssey Dynamic EQ solves the problem of deteriorating sound quality as volume is decreased by taking into account human perception and room acoustics. Dynamic EQ selects the best possible frequency response and surround levels moment-by-moment as volume is changed. The result is bass response, tonal balance, and surround impression that remain constant despite changes in volume. Audyssey Dynamic EQ combines information from incoming source levels with actual output sound levels in the room, a prerequisite for delivering a loudness correction solution. Audyssey Dynamic EQ works in tandem with Audyssey 2EQ to provide well-balanced sound for every listener at any volume level.
Audyssey Dynamic Volume: Audyssey Dynamic Volume corrects the problem of large variations in volume level between television programs, commercials, and between the soft and loud passages of movies. Dynamic Volume looks at the preferred volume setting by the user and then monitors how the volume of program material is being perceived by listeners in real time to decide whether an adjustment is needed. Whenever necessary, Dynamic Volume makes the necessary rapid or gradual adjustments to maintain the desired playback volume level while optimizing the dynamic range. Audyssey Dynamic EQ is integrated in Dynamic Volume so that as the playback volume is adjusted automatically, the perceived bass response, tonal balance, surround impression, and dialog clarity remain the same whether watching movies, flipping between television channels, or changing from stereo to surround sound content.
Music Optimizer: The Music Optimizer function enhances the sound quality of compressed music files. The Music Optimizer function works with analog inputs and PCM digital signals with a sampling rate below 48kHz.
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 to without the need to constantly adjust the volume to keep from waking family/neighbors.
Note: This feature only works with material encoded in Dolby Digital, Dolby Digital Plus, and Dolby TrueHD; the effect will vary from one soundtrack to another.
Audio Sync: Occasionally the audio and video signals are not properly synchronized, typically when using a progressive scanning DVD player. You can correct this by delaying the audio; options are 0 (no delay) to 200 milliseconds, in 10 millisecond steps.
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.
Zone 2: In addition to the main listening room, you can also enjoy audio playback from a different source in another room of your home using the receiver's Zone 2 capabilities. Using the receiver's supplied remote control, you can adjust the volume of Zone 2 independently from the main zone. The receiver features Zone 2 speaker terminals as well as Zone 2 pre-outs:
- Line Out: By using the line-level outputs on the TX-SR608 you can connect an external receiver or integrated amplifier in a second room, allowing you to listen to 7.1 surround in the main room and play a different audio source in another room of your home. The volume of Zone 2 is controlled by your optional integrated amp.
- Speaker Out: By using the speaker-level outputs on the TX-SR608 you can directly connect a secondary pair of speakers in another room of your home, allowing you to listen to 5.1 surround sound in your main room and play a different audio source in the other room. The volume of Zone 2 is controlled by the TX-SR608 receiver.
Note: By using the Zone 2 line level output, you can use the receiver's Zone 2 speaker terminal outputs to power a pair of front wide or front high speakers for Dolby Pro Logic IIz or Audyssey DSX, while also having surround back speakers connected (only one of these pair is active at any given time).
Bi-Amping Front Speakers: The Surround-Back speaker terminals can be reassigned and used along with the Front terminals to bi-amp the front speakers, providing improved bass and treble performance. When bi-amping the front speakers the receiver is able to power up to five speakers in the main room.
Assignable Digital Inputs: The Onkyo receiver is equipped with two optical digital inputs and two coaxial digital inputs. All four digital inputs are assignable to any of the inputs. You can choose auto decoding , PCM, or DTS for the digital audio inputs. Auto will decode the signal in its original form (Dolby Digital, DTS, PCM, etc), PCM decodes the signal to 2-channel, while DTS decodes only DTS formatted sources.
Binding Post Speaker Outputs: There are color-coded binding post connectors for the left front, right front, center, left surround, right surround, left surround back, and right surround back speakers. The binding posts are not 5-way because a plastic collar prevents their use with spade lugs. There are spring terminals for the Zone 2/Front-High/Front-Wide speakers.
Front-Panel AUX Input: The receiver features a front-panel 3.5mm auxiliary input for connecting a portable audio device such as your MP3 player. There is also a stereo RCA input on the front panel. These two inputs should not be used simultaneously.
Headphones: When headphones are plugged into the full-size 1/4" jack on the front panel, the speakers in the main room are automatically muted. If powered by the TX-SR608, the Zone 2 speakers are not muted.
AM/FM Tuner: With the built-in tuner you can enjoy AM and FM radio station. 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.
HDMI (v1.4): The TX-SR608 has six HDMI v1.4 inputs, five on the rear panel and one front. The front jack is fixed as the Aux input, while the five rear panel jacks are assignable to any of the other inputs. The receiver's HDMI circuitry allows the receiver to output an HDMI audio signal from its speaker outputs, headphone out, and HDMI out so you don't have to run additional analog or digital cables. The receiver uses HDCP (High-bandwidth Digital Content Protection), so only HDCP-compatible components can display the picture.
Video Scaling and Conversion: Composite and component video signals are converted to HDMI and can be scaled to the resolution set in the menu: Through (no scaling), Auto (automatically scaled to the highest resolution supported by the display), 480p, 720p, 1080i, or 1080p.
3D-Compatible: The TX-SR608's HDMI v.1.4 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 source product, HDMI cable, media 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 A/V receiver.
Component Video: There are 2 component video inputs and 1 component video output. The component video inputs and outputs have a bandwidth of 5Hz to 100MHz.
On-Screen Display (via HDMI): The Onkyo A/V receiver offers an on-screen setup menu through its HDMI output (no OSD via composite or component video). If your TV is connected to the composite video or component video monitor output, you will need to use the A/V receiver's front-panel display when changing settings.
Sleep Timer: From the remote, you can set the unit to automatically turn off after as much as 90 minutes or as little as 10 minutes; choices are presented in 10 minute increments.
Display Dimmer: The display brightness has three settings; Dim, Dimmer, and Normal.
Multi-brand Remote: The supplied RC-765M wireless remote is a multi-brand remote. The remote is pre-programmed to operate Onkyo components, as well as other popular brands of equipment, including Blu-ray, DVD, and HD-DVD players, satellite receivers, cable boxes, VCRs, televisions, CD and MD players and recorders, and cassette decks. Both the main room and Zone 2 are controlled by the remote.
