TX - NR5000E
OVER 50 YEARS OF ENGINEERING ACCLAIM
IS JUST THE STARTING POINT
ONKYO challenged its engineers to do the seemingly impossible, reinvent the flagship receiver concept–and don't leave
anything out. The result is the merging of science and design that represents our greatest technological accomplishment.
Now, learn about what makes this the most technologically advanced home cinema centrepiece on the market.
WOLFSON 192 KHZ/24-BIT DACS
FOR ALL CHANNELS
If you want the best perform-
ance possible from DVD-Audio,
Super Audio CD and whatever
other high-resolution formats
the future has in store, you'll
want these ultraprecise con-
verters. Widely recognized as
one of the industry's best, these sophisticated digital-to-
audio converters from Wolfson process more information
faster, deliver an impressive dynamic range, and are
virtually jitter-free.
WRAT
(Wide Range Amplifier Technology)
This ONKYO exclusive provides a movie cinema-like impact
and sound purity that conventional receivers can't match by
offering you three distinct advantages:
Low Negative Feedback Design: Most amplifiers return
part of the output signal to the amplifier input via a
negative feedback (NFB) that has a gain characteristic.
If the amount of NFB is large, the amount of counter-
electromagnetic force that reaches the amplifier from
the speaker will be great, and will disrupt the drive
mechanisms and adversely affect its transient response.
To avoid this, our engineers reduced the amount of
NFB by improving the open-loop frequency response
of the amplifier which results in low distortion across
the entire frequency range.
Elimination of Ground-Potential Fluctuations: The signal
amplitude at any point in the circuit is the difference in
potential between the signal level and its associated ground
level. If the ground potential fluctuates, even minutely, due
to the presence of electrical noise, the amplifier will not

have a stable reference point and not be able to reproduce
the signal from the input source accurately. The WRAT design
in the TX-NR5000E solves this problem with a component
and PCB layout that are carefully designed so that the earth
circuit branches form closed loops, and are all connected
to a common point. This prevents spurious current flow
between different ground points, and effectively eliminates
fluctuations in ground potential.
High Instantaneous Current Capability (HICC): Typical audio
signals are extremely complex, and consist of a wide range
of frequencies and amplitude levels. As you would expect
from a leader in amplifier design, ONKYO's WRAT amplifiers
provide better speaker control capacity and power output
than conventional amplifiers.
