Digital Inputs
The AVR-3300 is provided with four digital inputs, one coaxial and three optical. These are all
“addressable” – that is, they are not "locked" to any input, but can be assigned to the user's vari-
ous sources according to the type of digital output jack found on each – this is done at the time
of system setup. The use of addressable digital inputs with both optical and coaxial types sup-
ported will allow virtually any combination of audio/video source components to be accommodat-
ed.
Video Switching
Composite and "S" video inputs are provided for:
• DVD; VDP; TV/DBS; VCR 1; VCR 2/V AUX
Composite and "S" video recording outputs are provided for:
• VCR 1 and VCR 2/V AUX
In addition to composite and "S" video, the AVR-3300 also provides component video switching.
In anticipation of forthcoming DTV (North American Digital Television) set-top decoder boxes,
the AVR-3300 can accept a component video input (Y, R-Y, B-Y) signal from the TV/DBS input,
and another from the DVD player, such as Denon’s DVM-3700 and DVD-1500 models. A sepa-
rate dedicated component video output delivers the signals to the television monitor.
For maximum video fidelity, the AVR-3300 features a wideband video section, with very low
noise and extended frequency response.
The component video output has no on screen display, for best video pass-through quality, as
well as for compatibility with future video sources with progressive scanning outputs. With 27
MHz (-3 dB) bandwidth, the component video input signals are presented intact to the television
monitor, compatible with progressive and DTV sources.
Digital Signal Processing Section
Denon A/V components have incorporated Denon's DDSC (Dynamic Discrete Surround Circuit)
design concept for years. Essentially, DDSC features selected and dedicated processor(s)
matched with selected premium ancillary devices, which in total work together to provide a supe-
rior surround sound processing function than the highly integrated (and lower cost) IC solutions
used by competitors.
At the core of the AVR-3300 surround processor block is the newest Analog Devices SHARC
(Super Harvard Architecture Computer) 32 bit floating point DSP processor chip. The SHARC
processor has a 50 MIPS (millions of instructions per second) computing speed, with an 80
MFLOPS (millions of floating point operations per second) sustained speed capability, with a
peak throughput of 120 MFLOPS. The AVR-3300 is the first A/V receiver in it’s price class to fea-
ture the SHARC DSP.
