About the Sub DSP
The miniDSP Sub DSP is a compact 2-in/4-out digital audio processor designed for subwoofer integration, active crossovers, and system equalization. It uses a 28/56-bit DSP engine with 24-bit analog conversion and operates at 48 kHz. The unit provides unbalanced RCA analog inputs and outputs, USB connectivity for configuration, and USB or DC power. It supports parametric equalization and crossover processing through the applicable miniDSP software. It does not have the 2x4 HD’s SHARC processor, 192 kHz USB audio streaming, or TOSLINK digital input.
