The SBD44N 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 SBD44N are internal multi-pin connectors.
To build a full product, additional PCBs are needed with external connectors. See “Accessories” for details. The SBD44N is designed as a plug-in module to be placed on a motherboard, such as an I/O board or interface board.
KEY FEATURES
• 4 inputs, 4 outputs
• 48kHz sample rate
• Best-in-Class performance
• State-of-the-art digital processing
• Programmable User Interface
• Monitoring and permanent logging of key parameters such as temperature, signal level and gain reduction
• 144 FIR taps per output
• 100 presets
• Optional Dante and AES67 module available
• Multiple display and GPI / GPO support
• Full customization options
• Two DC inputs for potentiometers
• Two temperature sensor inputs
• One internal temperature sensor
• 100Mbit LAN with loop through
• Flexible signal routing matrix
• Small footprint, fits in most applications
• Cost effective
