Input and Output Notes

Features

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 192kHz/24-bit DACs for all channels.

Component Video Switching: In addition to HDMI, composite video, and S-Video switching, this unit can switch between high definition component video sources. There are 2 component video inputs and 1 component video output. The component video inputs and outputs have a bandwidth of 5Hz to 50MHz.

HDMI v1.3a Repeater: The TX-SR706 has four HDMI v1.3a inputs and one HDMI v1.3a output for connecting DVD players, HDTV set-top boxes, and other video components to your TV or projector. The receiver's HDMI circuitry allows the receiver to output an HDMI audio signal from its speaker outputs and HDMI out so you don't have to run and additional analog or digital cable. The HDMI inputs are also compatible with DVI, so TVs and displays with a DVI input can be connected by using an HDMI-to-DVI adapter cable, along with audio cables. The receiver uses HDCP (High-bandwidth Digital Content Protection), so only HDCP-compatible components can display the picture. The HDMI inputs can accept and switch 480i, 480p, 720p, 1080i, and 1080p signals to a TV, monitor, or projector. Each of the HDMI inputs can be assigned to any of the five rear panel A/V inputs (DVD, VCR/DVR, CBL/SAT, Game/TV). The receiver's HDMI input also supports the following functions.

  • Audio Formats: 2-channel linear PCM (32-192 kHz, 16/20/24 bit); Multichannel linear PCM (up to 7.1 ch, 32-192 kHz, 16/20/24 bit); and Bitstream (DSD, Dolby Digital, Dolby Digital Plus, Dolby TrueHD, DTS, DTS-HD High Resolution Audio, DTS-HD Master Audio).
  • xvColor: Increases detail and color space when watching movies on your television from an external device connected by HDMI through the TX-SR706.
  • 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 by your HDMI-compatible TV. With HDMI Lip Sync, the audio delay required to synchronize the audio and video is calculated and applied automatically by the AV receiver.
  • HDMI Control: This function allows CEC-compatible components or RIHD-compatible components connected via HDMI to be controlled with the TX-SR706.
  • Power Control: This feature allows you to link the power functions of CEC-compatible components or RIHD-compatible components connected via HDMI.
  • TV Control: This function enables you to control this AV receiver from an RIHD-compatible TV connected via HDMI.

HDMI Upconversion With Upscaling: The Onkyo TX-SR706 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 HDMI to give you the best picture quality possible. Using Faroudja DCDi Edge Technology, the receiver has the ability upscale incoming analog and digital video signals up to 1080p. You can specify the output resolution for the receiver's HDMI output and have the AV receiver upconvert  and upscale the picture resolution as necessary to match the resolution supported by your television. You can select from 480p, 720p, 1080i, 1080p, Auto or Through.

Bi-Amping Front Speakers: The Front L/R and Surround Back L/R terminal posts can be used with front speakers and surround back speakers respectively, or bi-amped to provide separate tweeter and woofer feeds for the front speaker, providing improved bass and treble performance. When the bi-amp feature is used, the AV receiver is able to drive up to 5.1 speakers in the main room.

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).

Dual-Zone Capability: You can use two speaker systems with the TX-SR706 receiver - a surround-sound speaker system up to 7.1 channels in your main listening room (Zone 1), and a stereo speaker system in a second room (Zone 2). The Zone 2 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 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 RCA line outputs to a receiver/amplifier or powered speakers in one room while powering a 7.1-channel speaker system in the main room; the output level of the RCA line outs for Zone 2 can be switched from fixed for 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.

iPod Compatible: The DS-A2x or DS-A3 Remote Interactive Dock for iPod (item # 580DSA2X and 580DSA3) provide an interface between an iPod digital media player and Onkyo TX-SR706. Once the iPod is docked you can control basic functions such as volume control, 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 an Onkyo home theater system.

Satellite Ready: The Onkyo TX-SR706 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 (part # 700XMTUNPK, sold separately), allowing you to receive XM Satellite Radio through the TX-SR706. 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-SR706 can also be connected to the optional SiriusConnect Home Tuner kit (part # 607SCH1, sold separately), which allows you to receive Sirius Satellite Radio through the receiver.

Multi-Channel Input: The receiver is equipped with a 7.1 multi-channel input for compatibility with external decoders or high resolution audio players such as DVD-Audio or SACD. The input consists of left front, right front, center, subwoofer, left surround, right surround, left surround back and right surround back RCA inputs.

Audyssey MultEQ: MultEQ detects speakers, and then sets levels, delays and crossovers, as well as measuring room acoustics. Using the receiver interface, it takes up to 6 measurements around the listening area and uses high-resolution equalization filters for satellites and subwoofers. MultEQ covers both frequency response and time domain (where most of the problems lie) across the entire listening area. The results are immediately obvious - a clear, well-balanced and natural sound. With the supplied speaker setup microphone, Audyssey MultEQ can measure the number of speakers connected, their sizes, crossover frequencies, and distances from the listening position and calculate the optimal speaker settings for you automatically. The supplied microphone is approximately 1-15/16" in diameter, 7/8" tall, and has a 19-3/4' cable that plugs into the front of the receiver. There is a threaded insert on the bottom of the microphone so it can be mounted on a tripod for accurate listening position placement. If you wish to setup the speakers manually, you can follow the procedure for Speaker Configuration.

  • Speaker Crossover: This receiver has a built-in high-pass crossover for each speaker in the system. This setting is available when the subwoofer is set to Yes. The frequencies that you can choose from are 40, 50, 60, 80, 100, 120, 150, 200 Hz or Full Range. Frequencies lower than the set crossover point are output by the subwoofer.
  • Speaker Distance: The distance from your listening position to each speaker can also be set manually. The front speaker distance can be set from 1 to 30 feet in 1-foot increments. The center and subwoofer settings can be up to 5 feet more or 5 feet less than the distance you set for the front speakers (30 feet max). The settings for the surround left, surround right, surround back left, and surround back right speakers are each individually adjustable, and they may be up to 5 feet more or 15 feet less than the distance you set for the front speakers (30 feet max).
  • Speaker Levels: You can manually adjust the level of individual speakers between -12dB and +12dB; -15dB to +12dB for the subwoofer.
  • Equalizer: You can adjust the receivers 7-band equalizer (63, 160, 400, 1000, 2500, 6300, and 16000 Hz) for each speaker manually from -6 to +6dB in 1dB increments.

Bass And Treble: You can independently adjust the Bass (50Hz) and Treble (20kHz) of the TX-SR706 from -10 to +10 dB.

  • 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. Adjustment varies from 5 (nothing subtracted from the L/R channels) to 0 (L/R channel output is cut in half).

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.

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. The choices are: Off, Low, and High.

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

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, MultEQ, MultEQ XT) to provide well-balanced sound for every listener at any volume level.

Music Optimizer: The Music Optimizer function enhances the sound quality of compressed music files. The Music Optimizer function only works with PCM digital audio input signals with a sampling rate below 48kHz and analog input signals.

AV 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 250 milliseconds, in 5 millisecond steps.

IntelliVolume: The IntelliVolume setup function allows you set a volume correction value in the range of -12dB to +12dB, in 1dB increments, 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 a maximum level for Zone 1 or Zone 2; specify any volume in the top half of the volume range
  • Power On Volume: specify the volume setting when the receiver is turned on for Zone 1 or Zone 2; specify any volume or Last to use 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

Picture Adjust: Using Picture Adjust, you can adjust the picture quality of the receiver's monitor output and reduce any noise appearing on your connected television display. You can adjust the following picture adjustments - Picture, Brightness, Contrast, Hue, Saturation, Edge Enhancement, and Noise Reduction.

HDMI: The TX-SR706 is equipped with four assignable HDMI inputs and one HDMI monitor output. The HDMI inputs will support uncompressed standard or high definition digital video along with the following  audio signals: 2-channel linear PCM, Multichannel linear PCM, and Bitstream. Audio signals received by the unit's HDMI inputs are output by the receiver's speaker outputs and HDMI out of the receiver. The HDMI circuit will accommodate a 1080p signal.

Assignable Digital Inputs: The Onkyo receiver is equipped with two optical digital inputs and three coaxial digital inputs. All five digital inputs are assignable.

Multi-channel Input: Labeled DVD, the TX-SR706 has a multi-channel input for connecting a DVD player, a high resolution audio player (such as a DVD-Audio or SACD player), or an external decoder. The input consists of left front, right front, center, subwoofer, left surround, right surround, left surround back and right surround back RCA inputs. You can also connect a component using only left and right audio jacks, if desired. Additionally there are composite video, S-video, and component video jacks for this input. This DVD input is included in the total of 6 A/V inputs.

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. The Zone 2 left and right speakers are also binding posts.

RI Remote Control Jack: The 1/8" RI remote control jack allows you to connect this receiver to other compatible Onkyo components.
