WRAT (Wide Range Amplier Technology)
Our low negative feedback WRAT concept breathes life
and vitality into your favorite music and soundtracks. It’s the
driving force behind the distinctive Onkyo sound. So what is
WRAT, and how does it work?
Low Negative Feedback Circuit Design
Negative feedback ampliers reduce distortion by feeding the
negative phase of the output signal back into the input signal to
cancel errors. Although this method is a cheap way to reduce noise, it
can inhibit the amp’s ability to reproduce high frequencies. It can also
dampen responsiveness, leaving music sounding at and dull. Our
WRAT design instead uses an ultra-low negative feedback circuit. The
design expands frequency response, boosts current, and allows audio
to blossom with startling energy and realism.
Less Distortion At High Volume
Another facet of WRAT is the closed ground loop circuit design
to keep the ground potential free of distortion. In a conventional
open-loop circuit design—where all circuits share the same link to
the power supply—any noise produced by voltage uctuation is
compounded, affecting audio quality. To avoid this, each circuit in the
M-5010 has its own separate link to the power supply, cutting noise
and promoting more reliable, efcient performance at any volume.
High Current for Wider Dynamics
Impedance uctuations and reex energy from the loudspeakers can
force your amplier to briey handle four to six times its usual load.
If its power supply is not up to scratch, signal clipping can occur and
audio quality suffers noticeably. A key element of WRAT is its ability
to deliver high instantaneous current, preserving a wide
100 kHz frequency response for expansive performance under the
most demanding conditions.
Three-Stage Inverted Darlington Circuitry
An important upgrade to the core WRAT concept is
Onkyo’s Three-Stage Inverted Darlington Circuitry, a low
negative feedback topology featuring a discrete triple
transistor array to cut distortion and boost current ow
to the speakers. As well as improving efciency, transient
response, and audio clarity, discrete transistors run cooler,
extending the life of your output stage for more years of
trouble-free service.
All-Analog Circuitry Delivers Ultra-Clear Sound
A standard integrated amplier has the dual task of both
processing and amplifying audio signals, and is therefore
susceptible to interference from digital circuitry. As a
dedicated power amp with all-analog circuitry, the M-5010
is protected against digital interference. When partnered
with a quality pre-processor, this unit offers all the benets
of pure analog amplication: a warm, musical, and full-bodied
sound.
High Output Power Supply
From input to output, signal purity is maintained at every
stage. Housed in a rigid anti-resonant steel-plate chassis
and nished with a tough one-piece aluminum front panel,
the M-5010 is highly resistant to vibration. A massive EI
transformer delivers a steady supply of power to the
speakers, while two large 10,000 μF capacitors, heavy-duty
transistors, and low-impedance copper bus bars work in
concert to enhance the power and delity of your audio
sources. A heavy-duty aluminum heat sink keeps the unit
running cool for superior reliability and longer life.
User-Friendly Features and Better Performance
The M-5010 sports banana plug-compatible speaker posts
to ensure a positive connection to the loudspeakers of your
choice. The unit is also equipped with selectable audio or
12 V triggers—providing automatic power on/off with your
home theater system—plus a rearside level adjustment.
A pair of inputs and outputs provide the multi-room
capabilities to which this amplier is perfectly suited.
