Inputs
XLR Analogue Inputs (Left and Right)
The XLR 3-pin sockets used for the analogue left and right channel inputs are
electronically balanced and have an impedance of greater than 10kΩ bridging.
Each XLR has the following connections:
n
Pin 1: Screen.
n
Pin 2: Signal +ve (hot)
n
Pin 3: Signal -ve (cold)
RCA Phono Inputs (Left and Right)
The left and right RCA (phono) analogue inputs are unbalanced and have an
impedance of greater than 20kΩ.
Input Level Adjustment
The input gain can be adjusted individually for the left and right channels using
the DIP switches and the preset potentiometers accessible on the rear panel. The
input gain can be set such that signals of +12, +18 or +24dBu generate full-scale
signals in the digital domain. Individual preset controls provide a further ± 3dB to
give an input level range of +9dBu to +27dBu.
The consumer input on the phono connector has a further gain of 10dB to provide
an input level range of -1dBu to +17dBu.
