Onkyo TX-SR706 THX Select2Plus A/V Receiver Announced


Onkyo has begun shipping its first A/V receiver to carry the new THX Select2 Plus Certification. The 7×100 watt TX-SR706 features HDMI v. 1.3a repeaters, 1080p Faroudja DCDi upscaling, onboard decoding for lossless and HD audio formats, Audyssey MultEQ and Audyssey DynamicEQ processing, and is compatible with both XM and Sirius Satellite Radio services.

The TX-SR706 is Onkyo’s first receiver to carry THX’s new Select2Plus™ Certification, which includes the new THX Loudness Plus™ volume control technology. This new processing algorithm compensates for the tonal and spatial shifts that occur when the volume level is reduced below the reference levels that the original soundtrack was mastered for. For instance, by slightly increasing the relative volume of the ambient sound at lower volumes, the impact of movies, music and games is much closer to what the sound engineer originally intended.

The TX-SR706 features four HDMI inputs, and is fully compatible with HDMI v. 1.3a, including 1080p and Deep Color™ 36-bit video signals. It features onboard decoding for Dolby Digital Plus, Dolby TrueHD, and DTS-HD Master Audio, and DTS-HD High Resolution making it fully capable of exploiting the high definition audio as well as video potential of the Blu-Ray disc formats, and all using a single HDMI cable connection. All HDMI inputs are upscaled to 1080p resolution using Faroudja’s DCDi Cinema technology.

To simplify setup and improve audio performance, Onkyo has included Audyssey’s acclaimed MultEQ room acoustics correction, as well as the Audyssey’s Dynamic EQ algorithm, which refines the receiver’s frequency response and surround levels moment-by-moment to compensate for deteriorations in the listening experience at different volume levels. These functions work together automatically to tailor the receiver’s output to correct for room acoustics, listening position, and playback-level distortions, delivering an overall experience that is a much closer match to what the audio production engineers originally intended.

The TX-SR706 also includes the company’s new Music Optimizer software, which improves the quality of MP3 and AAC encoded audio source material. While these compressed audio formats sound quite acceptable over small headphones or PC speaker systems, when reproduced on a full-scale home theater system the loss of high-frequency information becomes much more apparent. The Music Optimizer employs sophisticated equalization and optimization algorithms to overcome these faults, and enhances the reproduction quality of digitally compressed music.


The TX-SR706 also features Onkyo’s Powered Zone 2 capability, which can be used to power stereo speakers in a second room while listening to 5.1-channel sound in the main zone thanks to a dedicated set of zone 2 L/R speaker terminals. There is also a Zone 2 pre-out that can be used in conjunction with a dedicated zone amplifier or receiver. For those with main stereo LR loudspeakers that support bi-amplification, the back surround channels can also be reconfigured for this operating mode.

TX-SR706 For integration with whole-house control systems, the TX-SR706’s includes a bi-directional RS-232 port. Additionally, RIHD (Remote Interactive over HDMI) capability allows it to seamlessly integrate with other leading brand-name devices, including all Toshiba CE-Link equipment and selected Panasonic VIERA Link, Sharp, and Samsung products. The receiver is also compatible with Onkyo’s RI (Remote Interactive) iPod dock/charger models.

The Onkyo TX-S706 features a high quality AM/FM radio tuner, and features connections for both XM and Sirius satellite radio. It includes a newly redesigned pre-programmed learning RI (Remote Interactive) remote control unit with macros and mode-key LEDs. Finally, systems setup is even easier simpler to the implementation of a newly designed GUI (Graphical User Interface).

The Onkyo TX-SR706 is currently available at a suggested retail price of $899.
