Focusing on a Superior Audio Amplification Approach for Quality Stereo Sound

In the fast-paced world of home entertainment technology, change has become an understated word. Technologies now change so quickly
that the new becomes yesterday’s product before you barely become accustomed to it. Perhaps it’s time to refocus on what’s really important
for quality audio: first-rate sound with high power output. Forget about over-hyped processing technologies. If your receiver lacks the fundamental
amplifier design from the power supply through to the output stage, everything else is superfluous. The TX-8522 is built with this in mind.
Incorporating Onkyo’s proprietary Wide Range Amplifier Technology (WRAT) with an isolated power transformer and discrete output stage,
the TX-8522 is focused on maintaining the purity of music, radio and video sources while bringing meaningful features to your system.

Wide Range Amplifier Technology (WRAT

Onkyo’s collection of proprietary technologies ensures you can get the best
audio performance possible from the TX-8522.

Benefit 1: Uncommonly Low Negative-Feedback Design—Get cleaner sounds

on program peaks

NFB (negative feedback) is the most cost-effective way to reduce noise at
lower frequencies, but it will severely inhibit an amplifier’s ability to respond
to large signal gains (e.g. musical finales) and to produce sound at high
frequencies. The TX-8522 has a low negative-feedback design with audiophile­grade, close-tolerance components at critical points in the signal path to
achieve a frequency response out to 100 kHz for high-resolution formats
such as DVD-Audio and Super Audio CD, as well as for regular CDs, DVDs
and other music sources.

Benefit 2: Closed Ground-Loop Circuits—Enjoy greater maximum volume

without distortion

If an amplifier’s ground potential (voltage) fluctuates during playback, you can
expect noise. In an open-loop circuit design, where all circuits are connected
to the power supply via one loop (like on many amplifiers), the noise multiplies
exponentially. The TX-8522’s sophisticated closed-circuit design enables each
circuit to go and return directly to the power supply, which cancels any individual
circuit noise and keeps the ground potential free of distortion.

Benefit 3: High Instantaneous-Current Capability—Experience audio with

greater dynamics

After an amplifier outputs audio signals, speakers accumulate energy, reflex
and send energy back to the amplifier. The amplifier must immediately cancel
the speakers’ reflex energy and instantaneously send out the next signal. The
same high current is also necessary to handle speaker impedance fluctuations,
which can force an amplifier to provide four to six times its usual current load.
The TX-8522 has an instantaneous current capability that ensures audio output
is not affected by limited power.

High-Current, Low Impedance Drive

To get noticeable performance, a receiver’s ability to increase output power into
low impedances is essential. Without a consistent current flow through to your
loudspeakers, audio output is restricted. Without the appropriate parts and design
to support your amplifier, you will discover distortion on musical peaks, weak bass,
loss of dynamics, hardening of timbre and a collapsing soundstage. The TX-8522’s
discrete output stage and capable power transformer will drive speakers with
an impedance of up to 4 ohms—a demanding task. This power will give you
access to a wider range of speakers with which to build your audio system.

Speaker Playback and Remote Control for Another Room

With speaker A/B selectors and speaker terminals, the TX-8522 can be set up
for more than one room. Also, with the IR input you can control the receiver
when it is concealed inside a cabinet or when the user is in the remote zone
(where the second set of speakers is placed). Of course, it is necessary to use
a multiroom A/V distribution and control system such as those available from

®

and Xantech®. Also, you can use the IR output with an IR emitter to

Niles
remotely control other components.

iPod Playback through Onkyo’s Remote Interactive (RI
System Capability

With Onkyo’s RI system capabilities, you can connect other Onkyo components
to the TX-8522 and operate them through one single remote control. RI
capability also gives you the opportunity to integrate the iPod with the TX-8522
through Onkyo’s RI Dock for the iPod (DS-A1). Simply connect the dock to
the TX-8522, place your iPod in the dock and relish the fuller sound that just
can’t be experienced through headphones. RI capability also gives you remote
operability over your iPod for hands-off control over your digital music files.
The DS-A1 is compatible with most iPod models, and will also accommodate
the latest iPod releases.
