miniDSP kits are a new product concept for digital audio signal processing
applications: low cost, low power and great sound in a 3" square. With
our “one platform, many configuration” concept, miniDSP gives unparalleled flexibility to engineers, A/V designers and DIYers at a fraction
of the cost of typical alternatives. May it be a source mixer, a multi-way
digital crossover, a DAC unit or a custom A/V projects, it's all up to your
imagination to configure it the way you see fit.

At MiniDSP, we believe that great sound doesn't have to come at a great
price. Graphic equalizers, mixers, crossovers, wide range of low pass high
pass filters, dynamic range control, RMS meters etc., we packed it all up in
a tiny package with the ability to upgrade firmware from the click of a
mouse. No design shortcuts with our low noise electronic and double precision audio algorithms which all play a great role in making sure our kits
standout by their sound quality and not their price. Thanks to our real
time tuning and powerful programming capabilities, miniDSP is more than
a simple digital crossover: it’s a powerful development platform for a wide
range of applications ranging from DIY to OEM development.

Finally, engineered to be mixed & matched with the miniDSP I/O card
range or your custom I2S source, miniDSP is future proof and ready to answer the needs of flexible OEM applications.
