Audio Connections
Input Connections
For each input channel there is a female XLR connector for analogue inputs. The HOT, + or 'in phase' connection should be made
to pin 2 of the XLR connector.
The COLD, ‐ or 'out of phase' connection should be made to pin 3 of the XLR connector.
Pin 1 of the XLR connectors is internally connected to the chassis. The shield of the input cable should always be connected Pin
1 of the XLR to ensure that EMC performance and regulations are met.
Using unbalanced connections
Please note that the use of unbalanced connections is not recommended, however when connecting the amplifier to an
unbalanced audio source, the signal conductor should be connected to XLR pin2. The 'Cold' conductor or cable screen should be
connected to XLR pin 1 with a short connection made between pin 1 and pin 3.
