Product Details

miniDSP 2x4 HD Boxed USB DAC Digital Signal Processor

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: flexible para-metric EQ, Butterworth and Linkwitz-Riley crossovers, advanced biquad pro-gramming, 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 ena-bles substantial processing upgrades previously available only on more ex-pensive 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 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.

    A fantastic and very flexible little box of tricks - I originally bought a pair to use as 3 way active crossovers for a loudspeaker project I'm working on - My old TDLs are now singing, and the range of crossover and eq options is almost endless. It's very flexible in terms of routing - and can be used as a mono on/three or four way active crossover, a stereo active crossover, for sub management, or as a simple stereo unit for room correction.
    It seamlessly integrates with the (free) REW software to aid room integration.
    I have since bought a third unit to add corrective eq in the monitor path of a studio control room which up until now appeared to have insurmountable issues with it's frequency response in the low end, where it has proved to be very effective. Very happy!
    The only (very) slight reservation I have is that you have to be quite careful with gain structure to get the best performance and avoid a little bit of noise - to get the best out of the unit, it's better to hit the inputs quite hot and use some attenuation between the outputs and the power amps.

    DAC quality is poor and killing the soul of music. With my motherboard and chipset this card is very noisy. Good for sub integration...but never use for main speaker...
