Computer connectivity is required to perform acoustic measurements in your listening room and to generate
and download the digital room correction filters to the DDRC-22D. To configure the processor, connect the USB
port of the processor to a USB 2.0 port on your computer using the supplied cable. For measurements, connect
the UMIK-1 to a second USB port.
Once calibration and configuration is complete, the computer can be disconnected. The processor can then be
controlled from the front panel or via remote control – see Section 6, Using the DDRC-22D.
