The Dirac Series of 24/96 high-resolution audio processors with Dirac Live® are designed to fit into an existing system with minimum disruption, yet with the flexibility to allow for new and more cost-effective system configurations. The DDRC-22DA interfaces input sources via digital signals — AES-EBU on balanced XLR; coax/SPDIF on RCA, and optical/TOSLINK. On the output side, the balanced analog audio output can drive balanced or unbalanced audio amplifiers. The digital input source can be selected via the front panel or remote control. The DDRC-22DA is essentially a DSP powered DAC that can be simply inserted between a digital source (e.g. CDplayer/PC/AVR..etc) and an amplifier.

Application notes on DDRC-22DA

The Dirac Series of high-resolution audio processors from miniDSP incorporating Dirac Live® are an advanced hardware/software solution for digital room correction (DRC). In this application note, we'll give a quick run-down on how to use one. We'll assume that you've already obtained your Dirac Live software license and installed the Dirac Live Calibration tool for miniDSP software.
