 MG 5072

Introducing the long-awaited “reboot” of miniDSP’s best-selling 2x4 digital audio processor: the miniDSP 2x4 HD! This tiny powerhouse is jam-packed with miniDSP’s tried and proven audio processing functionality: large FIR banks, flexible parametric EQ, Butterworth and Linkwitz-Riley crossovers, advanced biquad programming, and delay on each output channel. miniDSP’s “one hardware many plugins” concept allows for many interesting future applications!

The upgraded on-board 400 MHz Analog Devices SHARC processor also enables substantial processing upgrades previously available only on more expensive platforms, such as 96 kHz internal processing for true high-resolution audio capability and assignable FIR filter taps for sophisticated equalization, crossover, and room correction capabilities. All to be accessed and programmed with miniDSP’s easy-to-use interface software.

I/O capabilities get an upgrade too, with the addition of USB audio streaming up to 192 kHz and a TOSLINK digital input. The miniDSP 2x4 HD kit will find application in full-sized hifi and home theater systems, on desktops, in cars, in recording studios — anywhere a compact, simple, yet surprisingly powerful DSP audio processor is needed.

Application notes on miniDSP 2x4 HD Kit

In this application note, we will show you how to design an active 2-way loudspeaker with the miniDSP 2x4 HD. Using the 2x4 HD, you can either create a conventional (Linkwitz-Riley or Butterworth) crossover, or a linear phase crossover.

In this application note, we will show you how to integrate a subwoofer with your existing loudspeakers by using a miniDSP 2x4 HD. You can use an existing preamp, or replace a preamp and a DAC with the miniDSP 2x4 HD. (In the latter case, you will need to program a remote control to adjust volume in the miniDSP 2x4 HD.)

In this application note, we show you how to use Room EQ Wizard (REW) and its integration with miniDSP to equalize your subwoofer.
