Lexicon SDP-40 - Manual (Page 13)

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.

Getting Started
JBL
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.
