4 in, 4 out DSP module with board-to-board connectors, including a certified 8 channel MILAN Listener.

SKU: Z07160
The SBD44P is a four input, four output Digital Signal Processor (DSP) intended for use in active loudspeakers or standalone processors for professional audio or high end home audio. All connections on SBD44P are internal multi-pin connectors.

To build a full product, additional PCBs are needed with external connectors. See “Accessories” for details. The SBD is designed as a plug-in module to be placed on a motherboard, such as an I/O board or interface board.
