About the DDRC-24

The miniDSP  DDRC-24 is the world’s smallest Dirac Live® hardware processor. Dirac Live®, the world’s premier room correction solution, is now available in an unbelievably compact hardware unit. Powered by a 400 MHz Analog Devices SHARC processor, the DDRC-24 retains the 4-channel output of its sister unit, the miniDSP 2x4 Hd, in order to allow applications like subwoofer integration or even 2-way loudspeakers together with Dirac Live® room correction in a single tiny hardware platform. The matrix mixer and crossover functionality is accessed and programmed with miniDSP’s easy-to-use interface software. An all in one unit with USB DAC + Dirac Live Room Correction + Speaker processing.

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 DDRC-24 will find application in full-sized hifi and home theater systems, on desktops, in cars, in recording studios anywhere a compact, powerful room correction processor is needed.

NOTE: The DDRC-24  requires a UMIK-1 to perform measurements of the room. Make sure to add it to your selection if you don't already own one.
