ABOUT THE SDP-5

Thank you for purchasing the SDP-5 Digital Controller, an 8- channel audio and video control center with independent zone monitoring that provides control of audio and video source selection in two zones at the same time. The SDP-5 includes eight configurable inputs, each of which can be assigned to its eight digital audio, eight analog audio, five composite video, five S-video, or three component video input connectors. The analog connectors can be configured for up to two 5.1-channel sources.

Inside and out, the SDP-5 is designed for possible future developments. The rear panel houses one RS-232 connector capable of performing configuration downloads and flash memory software upgrades and another capable of supporting future developments. The rear panel also includes two removable access panels to accommodate connectors for emerging technologies.

More than just an audio and video control center, the SDP-5 offers the latest version of the critically acclaimed LOGIC7® decoding, which creates a 7.1-channel output signal from stereo, 5.1-, and 6.1-channel sources. Unlike other decoders, LOGIC7 decoding is compatible with all input sources and requires no special encoding. Because the improvement it provides is clearly audible, LOGIC7 is widely regarded as the finest available.

In addition to LOGIC7, the SDP-5 offers Dolby Digital Surround EX, Dolby Pro Logic II, Dolby Pro Logic, dts 96/24, dts NEO:6, dts-ES, THX Ultra2, and THX Surround EX decoding. THX Ultra2 Certification guarantees that the SDP-5 meets the highest THX specifications.

With four floating-point SHARC™ digital signal processing (DSP) engines, the SDP-5 boasts enormous processing power. These powerful processors perform custom processing such as LOGIC7 decoding, bass enhancement, dialog enhancement, auto azimuth, 5-speaker enhancement, bass management, high-precision digital crossovers, and audio controls. These features are available at sample rates up to 96kHz, with 24-bit resolution to retain top performance from all sources. In addition, a fifth DSP engine is dedicated to decoding multi-channel compressed audio sources.

The SDP-5 is one of the most advanced audio and video control centers available. High-precision 24-bit/96kHz A/D converters can be used to convert stereo analog audio input signals to digital signals, allowing the SDP-5 to provide the benefits of precise digital signal processing without sacrificing signal integrity. Alternatively, stereo analog signals can bypass A/D conversion and internal processing, following a pure signal path directly to the output connectors.

Digital audio input signals are processed through a two-stage phase lock loop for extremely low intrinsic jitter and high rejection. Auto azimuth technology corrects timing and level imbalances in stereo sources, ensuring exceptionally accurate playback of surround- encoded sources. A digital audio pass-through output is available for recording digital signals with a CD recorder or a similar component.
