Onkyo TX-NR5000E manual Optimum Gain Volume Circuitry, NON-SCALING Configuration, Pure Audio Mode

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.

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.

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

people who do not

own a subwoofer,

and for users who

own high-perform-

ance front speakers and feel that with certain music or

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

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.
