The miniDSP 2x4 HD is a high fidelity, high performance digital-to-analog converter (DAC) and digital signal processor (DSP) with powerful audio processing functionality. The 2x4 HD features USB and TOSLINK digital inputs, two analog inputs and four analog outputs. 

Functions

• USB DAC audio streaming up to 192kHz and a TOSLINK digital input

• Programmable active crossover

• Programmable subwoofer crossover

• Programmable parametric equalizer

• Room response correction equalizer (requires UMIK-1 microphone and REW software)

• Channel delay and level control

• 400MHz Analog Devices SHARC processor allows 96kHz internal processing for true high-resolution audio capability

The miniDSP 2x4 HD includes miniDSP’s renowned Device Console application software with perpetual updates for powerful and easy programming. The crossovers and/or filters can be configured in real time from a PC or Mac environment. Once the miniDSP is configured, the device can operate standalone and no longer requires a computer connection.
