TX-SR705 THX™ Select2™ Certified HDMI v1.3a 7.1-Channel A/V Receiver

Redefining its Class with Controlled Power and High-Definition Prowess

You’ll be hard-pressed to find a mid-range home theater A/V receiver that packs the TX-SR705’s amplification power and audio processing capabilities. It might be comforting to look to its THX™ Select2™ certification for confirmation, but as the THX engineers have seen, there’s a lot more here than just efficient amplifier drive ability and all-round home theater performance. The TX-SR705 breaks new ground in the mid-range category by featuring not only the lossless audio codecs, Dolby® TrueHD and DTS-HD® Master Audio, but also the most advanced version of HDMI.And with a wealth of other class-leading features — 1080p video processing, Audyssey’s MultEQ® XT technology for room calibration and advanced processing devices from Texas Instruments and Cirrus Logic — nothing has been sacrificed in the making of this remarkable home theater component.

THX Select2 Certification for a Better Class of Home Theater

From its development stage to its final conception, the TX-SR705 has been engineered to comply with the most stringent requirements of THX Select2. Select2 certification means that the TX-SR705 is ideally suited to a home theater where the viewing distance from screen to seat is around 10-12 feet and the room volume is no greater than 2000 cubic feet. Among its technologies, Advanced Speaker Array (ASA) digitally reconfigures surround speakers for three listening modes: movies, music and gaming. The THX stamp of approval also covers an A/V receiver’s amplification characteristics. For example, under THX testing, the TX-SR705 has been proven to provide 12.5 amperes of peak current for its front channels and 6.2 amperes for its surrounds.

Processing 1080p Video and High-Resolution Audio via High-Definition Multimedia Interface (HDMI 1.3a)

With three HDMI inputs, you can receive and switch the latest high definition components—Blu-ray Disc and HD DVD players, satellite and cable boxes, media centers and gaming consoles — for a pure, one cable digital connection to an HDTV. HDMI also delivers the latest high-definition audio formats — Dolby TrueHD, DTS-HD Master Audio, Dolby® Digital Plus and DTS-HD® High Resolution Audio — to be processed by the TX-SR705’s onboard decoders. These new formats enable unprecedented quality, including bit-for-bit reproduction in the case of TrueHD and Master Audio. Also, HDMI 1.3a gives you greater bandwidth to deal with higher resolutions, 36-bit Deep Color™ and high frame rates.

HDMI and Component Video Upconversion for a Single Output to High-Resolution Displays

The TX-SR705’s HDMI inputs can receive pristine digital video from HDMI-enabled components, for a single-cable output to a display device with an HDMI or DVI connection. The TX-SR705 can also upconvert analog signals to HDMI so that all connected video sources can be outputted via one cable. And if your display doesn’t have HDMI capability, you can use the HD-quality component video connections, which will also cover your S-Video and composite video sources. To support progressive scan, the TX-SR705 features a deinterlacing chip with Faroudja DCDi Edge™ (Directional Correlational Deinterlacing). This technology helps to effectively eliminate video artifacts from HDTV images.

Audyssey MultEQ XT for Powerful Room Acoustics Correction

MultEQ XT is Audyssey’s most powerful built-in solution for countering distortion in dedicated home theaters. This technology detects speakers, and then sets levels, delays and crossovers, as well as measuring room acoustics. Using the receiver interface, it takes up to eight measurements around the listening area and uses high-resolution equalization filters for satellites and subwoofers. MultEQ XT covers both the frequency response and the 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.
