To preserve the fidelity of the high bit data provided by the DDSC-D SHARC processor section,
the AVR-3300 features full 24 bit 96 kHz premium grade DACs on all six audio channels. Unlike
other processors which use cheaper integrated codecs (combination A/D and D/A chip), the
Denon DDSC-D philosophy extends through the D/A section, featuring full 24 bit 96 kHz digital
filters for all six channels, followed by full 24 bit 96 kHz premium Analog Devices AD-1855
DACs.
The AVR-3300 features a unique Denon-designed digital interface receiver, that can accept high
bit/high sampling stereo PCM digital audio, up to 24 bit word length and up to 96 kHz sampling
frequency. Recently issued DVD-Video discs with 24/96 audio, such as the Chesky Records and
Classic Records 24/96 audiophile DVDs, provide a very high resolution stereo presentation with
far greater dynamic range and frequency response, compared to CD. Denon’s newer DVD play-
er models, such as the DVM-3700, are equipped with digital outputs that provide a real 24 bit,
96 kHz stereo PCM bitstream.
When a compatible Denon DVD player is connected digitally to the AVR-3300, the listener expe-
riences real 24 bit/96 kHz stereo audio via direct digital decoding and the use of the real 24
bit/96 kHz digital filters and DACs employed in the DSP output section. Other receivers cannot
handle 24/96 kHz PCM sources, and downsample and/or truncate accordingly, providing only
CD-quality audio with these higher resolution DVDs. Most competitive DVD players also truncate
and downsample the DVDs 24/96 PCM bitstream, outputting only a CD-equivalent 16 bit, 48
kHz PCM bitstream at their digital output(s). In the presence of a 24/96 digital input signal, the
AVR-3300 indicates via the front panel display that real 24/96 decoding is occurring, and switch-
es to stereo mode automatically for best sound (surround simulations are disabled for 24/96
pure stereo sources).
Intelligent Volume Control
The AVR-3300 features a variable volume control design, with a "smart" volume control algo-
rithm. Via remote control, the volume is raised or lowered in gentle 1 dB steps, or more quickly if
the volume up/down buttons are pressed and held. The master volume knob on the front panel
has the ability to detect whether it is turned quickly or slowly and react accordingly. If the user
slowly turns the master volume knob up or down, the volume is adjusted in 1 dB increments
accordingly. Give the knob a quick twist up or down, and the volume will raise and lower with
greatly increased speed (much like an analog volume control).
