UDIO INPUT AND OUTPUT CONNECTIONS
Digital inputs (DDRC-22D and DDRC-22DA)
Connect up to three digital sources: AES-EBU on XLR, S/PDIF on RCA, or optical (TOSLINK). These
sources can be selected between by using the front panel or an infrared remote (not included).
The digital inputs of the DDRC-22D and DDRC-22DA accept sample rates from 20 up to 216 kHz.
Note: the digital inputs accept a stereo PCM digital signal only. They do not accept encoded or
multichannel digital audio (such as Dolby Digital or DTS).
Digital outputs (DDRC-22D)
Connect one of the digital outputs to your DAC or other device with a digital input. All digital
outputs are simultaneously active, so multiple output connections can be made if necessary.
Note: the digital outputs of the DDRC-22D operate at 96 kHz sample rate. Any connected DAC
must support this sample rate. (The digital inputs of the DDRC-22D and DDRC-22DA accept any
sample rate up to 216 kHz.)
Analog inputs (DDRC-22A)
Connect the analog inputs to your preamp or other analog source. The inputs are balanced XLR
connectors, so in the event that your other equipment has only single-ended (RCA) connections,
use suitable RCA-XLR adapters or adapter cables.
Analog outputs (DDRC-22A and DDRC-22DA)
Connect the analog outputs directly to your amplification. The outputs are balanced XLR
connectors, so in the event that your other equipment has only single-ended (RCA) connections,
use suitable XLR-RCA adapters or adapter cables.
