Meet the highly anticipated "reboot" of the best-selling miniDSP 2x4 digital audio processor - the miniDSP 2x4 HD! This compact device is packed with tried and tested audio processing features including versatile parametric EQ, Butterworth and Linkwitz-Riley crossovers, advanced biquad programming, and individual output channel delay.

With miniDSP's "one hardware many plugins" concept, the possibilities for future applications are endless. The upgraded 400 MHz Analog Devices SHARC processor enables substantial processing upgrades, such as 96 kHz internal processing for true high-resolution audio and assignable FIR filter taps for advanced equalisation, crossover, and room correction capabilities. And with user-friendly interface software, accessing and programming these features is a breeze. Not only that, the miniDSP 2x4 HD boasts upgraded I/O capabilities with USB audio streaming up to 192 kHz and a TOSLINK digital input.
