ABOUT THE SDP-40HD

Thank you for purchasing the SDP-40HD Digital Controller, a reference-quality, 12-channel audio and video control center with independent zone monitoring to provide control of input source selection in three zones at the same time. As flexible as it is powerful, the SDP-40HD includes 12 inputs, each of which can be configured and assigned to any of its 6 HDMI™ (High-Definition Multimedia Interface™), 13 digital audio, 8 analog audio, 2 composite video, 3 S-video, or 4 component video input connectors. The analog audio input connectors can be configured for stereo or 5.1-channel sources.

The SDP-40HD features an HDMI interface that enables the transmission of uncompressed digital audio and video signals through a single connector. The SDP-40HD can pass digital video signals of up to 720p/1080i, and multiple digital audio channels (5.1 channels) at sample rates of up to 96kHz through the HDMI interface. The SDP-40HD also supports the High-bandwidth Digital Content Protection (HDCP) technology that comprises data encryption and authentication of the partner equipment.

Beyond the HDMI connectors and standard 5.1-channel audio output connectors, the rear panel includes stereo rear and stereo subwoofer connectors to provide even more audio channels. All Main Zone audio output connectors include 24-bit/96kHz D/A converters operating in dual differential mode. In addition, the SDP-40HD includes balanced audio output connectors for all Main Zone and Zone 2 channels.

Two RS-232 connectors are provided for serial control. One of the connectors is for performing flash-memory software upgrades and backing up or restoring configuration files. The other connector is reserved for possible upgrades.

More than just an audio and video control center, the SDP-40HD features the latest version of Harman’s critically acclaimed Logic 7®

decoding, which derives 7.1-channel output from stereo, 5.1-, and 6.1-channel sources. Unlike other decoders, Logic 7 is compatible with all input sources and requires no special encoding. Because the improvement it provides is clearly audible, Logic 7 decoding is widely regarded as the finest available.

In addition to Logic 7, the SDP-40HD is also equipped with Dolby® Digital Surround EX™, Dolby Pro Logic®, Dolby Pro Logic II, Dolby Pro Logic IIx, DTS 96/24™, DTS NEO:6®, DTS-ES®, THX Ultra2™, and THX Surround EX™ decoding. THX Ultra2 certification guarantees that the SDP-40HD meets the highest THX performance specifications.

With four 32-bit floating-point SHARC™ digital signal processing (DSP) engines, the SDP-40HD offers unparalleled processing power. These DSP engines perform custom processing such as Logic 7 decoding, bass enhancement, dialog enhancement, auto azimuth, 5-speaker enhancement, bass management, high-precision digital crossovers, and tone controls. This processing is available at sample rates up to 96kHz, with 24-bit resolution to retain top performance from all input sources and listening modes. A fifth DSP engine is dedicated to decoding multi-channel compressed audio sources.

High-precision 96kHz/24-bit A/D converters can be used to convert stereo and 5.1 analog audio input signals to digital signals, allowing the SDP-40HD to provide the benefits of precise digital signal processing without sacrificing signal integrity.

Digital audio input signals are processed through a two-stage phase lock loop for extremely low intrinsic jitter and high jitter 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 option is available for recording digital signals with a CD recorder or a similar component.
