Analogue Input Adjustment
The Input Peak Digits setting (see System Menu: Volume) sets the analogue input gain for
full-scale digits in the digital domain. The preset potentiometers next to the analogue inputs
allow an additional adjustment of this value by ±3dB.
AES/EBU Input
The digital input XLR 3 pin socket has an impedance of 110Ω. It has the following
connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-phase
The signals on this connector should meet the IEC 60968 specification.
XLR Analogue Outputs (Left and Right)
The XLR 3 pin output plugs are electronically balanced with an output impedance of less
than 50Ω. They have the following connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-phase
AES/EBU Output
The digital output XLR 3 pin plug has an impedance of 110Ω. It has the following
connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-phase
The signals on this connector comply with the IEC 60968 specification.
Remote Inputs and Outputs
The 15-way ‘D’ type socket connector presents 8 active low inputs and 6 open collector
outputs. The inputs are used to remotely select one of 8 configuration setups (see System
Menu: Setups) when the Remote Loading function is enabled. The outputs are not currently
used. It has the following connections:
Pin 1: Active low input 1
Pin 2: Active low input 2
Pin 3: Active low input 3
Pin 4: Active low input 4
Pin 5: Active low input 5
Pin 6: Active low input 6
Pin 7: Active low input 7
Pin 8: Active low input 8
Pin 9: Signal ground
