Wide Range Amplifier Technology (WRAT)
WRAT is the backbone of the TX-SR574’s amplifier design and is centered on
three core elements:
1) A low-negative-feedback design that ensures a fuller sound at higher frequencies;
2) Closed ground-loop circuits that mitigate individual circuit noise and keep
the ground potential free of distortion;
3) A high-instantaneous current capability that effectively handles reflex energy
from the speakers and impedance fluctuations to offer dynamics similar to
those experienced in a movie theatre.
WRAT ensures the audio performance necessary for a range of video content with
surround sound, as well as providing a solid platform for reproducing music
sources like DVD-Audio, Super Audio CD, PCM CDs, and digital files like MP3s.
Component Video Upconversion with TBC (Time Base Corrector)
All playback components connected to the TX-SR574 can be upconverted to
component video for one convenient connection to the latest displays. During
upconversion, each signal incorporates a synchronization pulse (synch) that
represents the beginning of each video signal. These synchs need to be highly
precise in amplitude and timing to eliminate clock jitter, which can substantially
degrade the images on high-definition displays. By incorporating a time base
corrector in the upconversion process, inconsistencies in the signal timing can
be corrected thereby ensuring the highest picture quality possible.
Component Video Switching (50 MHz) with HDTV Connectivity
With three component video inputs, you can have up to three of today’s latest
A/V components—think DVD/universal players, cable/set-top boxes, DVRs and
the latest gaming consoles like the Xbox
® — connected simultaneously for output
to the latest high-definition displays. With a frequency range out to 50 MHz, you
have more than enough bandwidth to pass a progressive scan DVD signal (at least
12 MHz needed) and a 720p signal (at least 37 MHz needed) to high-definition
displays with no video signal deterioration. Also, the convenience and simplicity
of one component video output for all sources fit well with the TX-SR574’s focus
on ease-of-setup.
Incorporating the Most Advanced Surround Formats Available
The TX-SR574 has the onboard codecs—Dolby Digital EX, Dolby Pro Logic IIx,
DTS-ES, DTS 96/24 and DTS Neo:6—to effectively reproduce stereo and
multichannel sources in enveloping 6.1 or 7.1 surround sound. And with the
upcoming release of HD-DVD and Blu-ray Disc, Dolby Digital and DTS have
prepared audio formats that represent the future of digital audio entertainment. By
connecting an HD-DVD or Blu-ray Disc player with the respective high-definition
audio codecs to the TX-SR574 via its 7.1-multichannel inputs, you will be able to
enjoy superior audio quality with a bit-rate of up to 1.5 Mbps*, almost twice that
of existing codecs. The new codecs are back-compatible with existing codecs.

Extended Crossover Adjustment
Crossover control determines the frequency at which the subwoofer takes over
bass-reproducing responsibilities from the main speakers. If the crossover is too
low, there’ll be a dip in the mid-bass response. If it’s too high, there’ll be frequency
duplication (resulting in a muddy bass sound). Your room’s acoustical environment
can also influence the crossover setting. The TX-SR574 lets you choose from a
wide range of frequencies—40/50/60/80/100/120/150/200 Hz—which enables
you to accurately set the correct crossover for different speaker packages. You’ll
also be able to better mix and match different speaker brands.
RI System Integration and iPod Connectivity
Onkyo’s proprietary RI system enables you to integrate different Onkyo components
for control through one remote console. It is also the port by which you can make
the iPod part of your system with the RI-Dock for the iPod (DS-A1). The DS-A1, as
noted by What HiFi? (UK Awards 2005 edition), offers a “heftier and more detailed
sound” than by simply connecting via a cable. The dock will also give you the
chance to playback your digital photos through your home theatre; the ability to
recharge your iPod; and the opportunity to transfer files from iTunes directly to
your home theatre system.

Adding More Options to the Home Theatre Experience
The design philosophy behind the TX-SR574 makes good sense. Provide on-demand power for all channels; add powerful processing capabilities
and dependable build quality; and stack it with versatility and options. The TX-SR574 takes today’s most sought after home entertainment
components—like DVD recorders, cable/set-top boxes and gaming consoles—and conveniently switches between them with a single component
output to HDTV. It will also upconvert any other components connected by S-Video and composite connections. And when it comes to music
and movie sources, the TX-SR574 accommodates the most contemporary formats available, even the yet-to-be-released surround formats for
HD-DVD and Blu-ray Disc. And if you want to broaden your choices even further, the TX-SR574 provides access to the iPod with the appropriate
set-up and peripherals. Such competitively priced completeness is bound to attract attention.
