ADIGITAL INPUT SELECT: Selects any of the 4 digital inputs. Positions 1, 2 and 3 correspond to the RCA phono style S/PDIF and the XLR AES / EBU inputs. Position 4 corresponds to the A.T.&T. Optical input. When the switch is changed the output mutes until "VALID DATA" is "LOCKED" by the AES 21 jitter reduction chip.
B32, 44.1, 48: 3 red LEDs that indicatethe sample rate of the incoming data. CD's are always 44.1 while the sample rate of DAT's may be any of the three.
CVALID DATA LED: Lit when the unit has a readable input that can be converted to audio. This immediately indicates a "good" input
DERROR LED: Lit when audio is muted. There are several conditions that will cause this. 1) Warm - up timer approximately 30 seconds. 2) momentary loss of data including changing the DIGITAL INPUT SELECT. 3) any cable related loss of data, unreadable data or data errors. 4) The
EVOLUME: This is a precision 4 stack stepped attenuator. Because some users prefer to feed the outputs of this unit directly to their power amps this VOLUME becomes their main volume control. Other users with a preamp can use this control to match the output of the D to A to thier analogue sources avoiding level jumps.
