About the 2x4 HD
The miniDSP 2x4 HD is a compact 2-input/4-output digital signal processor and USB audio interface for active loudspeaker crossovers, subwoofer integration, equalization, time alignment, and room-correction workflows. It uses a 400 MHz Analog Devices SHARC floating-point DSP and is configured from a Windows or macOS computer using miniDSP plug-ins. Sources can be connected through stereo RCA analog input, optical TOSLINK, or asynchronous USB Audio Class 2; processed audio is available from four RCA outputs and through multichannel USB audio return. Its DSP feature set (depending on the installed plug-in) includes parametric EQ, IIR crossovers, FIR filtering, delay, routing, polarity control, gain adjustment, four stored presets, and IR remote-learning functions. The manufacturer continues to list the 2x4 HD in its product/manual ecosystem, so it is not indicated as discontinued.
