Onkyo TX-SR576 and TX-SR506
 Onkyo TX-SR576 Black
These receivers each include three HDMI inputs, Audyssey
2EQ automatic room correction, and also mark the company's first
implementation of its new Music Optimizer software, which improves
fidelity for MP3 and AAC encoded digital music sources.
The
Onkyo TX-SR576 and TX-SR506 are the first receivers at these price
points to include the company's dual-source Powered Zone 2 capability,
which allows the receiver's rear surround amplifier channels to power
stereo speakers in a second room while still listening to 5.1-channel
sound in the main zone. The receiver is capable of processing separate
multichannel and stereo sources simultaneously for the main and second
zone, or processing a single source for both. There is also a Zone 2
pre-out that can be used in conjunction with a dedicated zone amplifier
or receiver. Finally, for those with premium "biampable" loudspeakers,
where the bass and midrange/treble drivers are each driven by separate
amplifiers, the rear surround channels can be reconfigured for this
more powerful operating mode.
 TX-SR506 Silver The Audyssey 2EQ automatic
calibration system featured on the Onkyo TX-SR576 and TX-SR506
receivers employs an included calibration microphone to analyze the
system's acoustical output at three positions in the listening area.
The receiver sends test signals to each speaker in turn, then uses the
inputs from the microphone to adjust channel level and time delay
settings for each speaker. By taking readings in three different
positions in the theater room, the receiver can be calibrated to the
speakers and environment, delivering optimal response throughout the
room rather than just at the 'sweet spot' directly in front of the
screen.
Additionally, these receivers are among
the first products ever to employ Audyssey's Dynamic EQ algorithm,
which adds moment-by-moment refinement to the receiver's frequency
response and surround levels in order to compensate for
volume-dependent deteriorations in the listening experience,
particularly at low volume lev els. When used in combination with the
Audyssey 2EQ system, this feature tailors 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.
 TX-SR576 Rear For
sharp and accurate audio reproduction, both receivers employ 32-bit DSP
processing and 192 kHz/24-bit digital-to-analog converters on all
channels. Each includes 7.1-channel surround processing for Dolby
Digital EX, Dolby ProLogic IIx, DTS-ES, DTS 96/24, and DTS Neo:6. The
receivers also include a user-selectable eight-setting subwoofer
crossover adjustment for ideal integration of any subwoofer/satellite
speaker system.
Both receivers are designed to
take complete advantage of the company's RI (Remote Interactive) iPod
dock/charger models. The receivers include preprogrammed RI-compatible
remote controls, and are available in either black or silver finishes.
The Onkyo TX-SR576 and TX-SR506 will be available in April at suggested retail prices of $479 and $379 each, respectively.
