Pure Audio Mode - Onkyo TX-NR5000E Brochure & Specs

to isolate each channel from crosstalk and AC-line interference,
is the kind you find in high-end audio equipment. Custom
high capacity low ESR filter capacitors give you greater
power delivery at low frequencies, plus tremendous contin-
uous power reserves during the most dynamic sound effects
and music demands. For hi-fi purists, discrete, precision
matched output transistors provide faster switching speed,
which translates into a wider dynamic range.
OPTIMUM GAIN VOLUME
CIRCUITRY
To produce volume at low levels, conventional volume
attenuation methods must initially drop a signal close to
the noise floor. This often taints the signal with a small
amount of noise, which becomes amplified when the signal
itself is amplified. Optimum Gain Volume Circuitry solves
this problem by adjusting the gain so that less than half
the typical amount of attenuation is needed. This ensures
that the signal never comes close to the noise floor, and
thereby eliminates the possibility of noise contamination
that plagues conventional volume-attenuation.
NON-SCALING CONFIGURATION
If you already own a Dolby Digital
receiver, you can choose to send
the Low Frequency Effect signal
(LFE) to the front left and right
speakers instead of to the sub-
woofer. This flexibility is provided by
all manufacturers for the benefit of
soundtracks, their front speakers can reproduce the LFE
signal better than their subwoofer can. Given the ease
with which digital signals can be handled, it is perhaps
people who do not
own a subwoofer,
and for users who
own high-perform-
ance front speakers
and feel that with
certain music or
unsurprising that nearly all manufacturers of Dolby Digital
receivers opt for a shortcut here; they add the 24-bit LFE
to the front speaker signals before the LFE are converted
to analogue. The price you pay for their convenience is data
scaling. To avoid the possibility of overflow (the result of
the added digital values exceeding 24 bits), this approach
requires that one bit of music or soundtrack data be truncated
off each data-word before they are added.
Our philosophy is simply not to mess with the signal (or
your music and soundtracks.) No shortcuts. The TX-NR5000E
employs a non-scaled circuit design that fully converts all
the signals to analogue before the LFE is added to the front
channels. This eliminates the need for scaling altogether,
and preserves every bit of the original digital data. Though
this design is more expensive and difficult to implement,
we think it's an ONKYO design difference you'll hear, and a
shortcut you'll be glad we didn't take.

PURE AUDIO MODE

When you select the Pure Audio Mode, the video signal is
shut down (resulting in a blank screen), and the receiver
concentrates on delivering the purest audio possible. This
is ideal for those music lovers who want to sit back and
enjoy their compact discs, DVD-Audio, Super Audio CDs
or multi-channel music discs in an unadulterated listening
environment.
TRANSPARENT MULTIWAY
BINDING-POST SPEAKER TERMINALS
If you're investing in a receiver of this calibre, you prob-
ably have high-performance speakers to match. That's
why we included heavy-duty, transparent multiway binding-
post speaker terminals for all channels. As well as being
aesthetically pleasing to the eyes, they give you a larger
"pipe" through which to push the audio signal. The result is
a low impedance design approach all the way down to the
speaker terminals and a purer signal path and improved
sound quality.
