Thank you for purchasing the SDP-40 Digital Controller – a reference-quality, 12-channel digital surround processor with built-in digital audio processing, 12 configurable inputs, and 3 independent zones. Beyond the standard 5.1-channel outputs, the unit features stereo rear and stereo subwoofer outputs. Additionally, the SDP-40 provides balanced audio outputs for all Main Zone and Zone 2 outputs.
Inside and out, the unit is designed with an eye toward the future. The rear panel has stereo auxiliary outputs to provide more audio channels, and a removable access plate to accommodate connectors for new technologies. Inside, three expansion slots are available for future upgrades. The system software can be upgraded in the field using the RS-232 port.
The SDP-40 features LOGIC7™ technology. LOGIC7 creates a 7.1-channel output from any input signals (except mono input signals). Unlike many decoders, LOGIC7 is compatible with most input signals and requires no special encoding. Because the improvement it provides is clearly audible, LOGIC7 is widely recognized as the finest surround decoder available.
Dolby Digital, THX Surround EX, dts, dts-ES, and Dolby Pro Logic II are also included. THX certification guarantees that specifications meet the highest standards set forth by Lucasfilm’s Home THX division.
Four 32-bit DSP engines provide enormous processing power. Custom algorithms process 96kHz/24-bit audio in all listening modes. A fifth processor, the Crystal 49326 Audio DSP, decodes multi-channel compressed audio data sources. Three expansion slots make it possible to more than quadruple available processing power.
Analog sources are processed at 96kHz. Digital sources use a two-stage phase lock loop for extremely low intrinsic jitter with high-jitter rejection. Each MAIN AUDIO OUTPUT incorporates 24-bit/192kHz digital-to-analog converters operating in dual differential mode to ensure the highest quality performance. There are two broadcast-quality video switchers. The ultra-wide bandwidth component video switcher accepts any analog component or RGB video input type. The S- and composite video switcher accommodates high-quality NTSC, PAL, or SECAM video input types.
Input configuration allows any source to be assigned to any input. The unit will automatically switch between digital and analog sources. The intuitive user interface, with color on-screen display, makes it easy to configure the unit. Three subwoofer outputs and sophisticated routing provide intelligent bass management.
With its unique combination of power, flexibility, and expandability, the SDP-40 is equipped for the needs of today and the demands of tomorrow.
