Tip: Take a look at the table in this blogpost to see which power supply to choose for this product.
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.
