Audio Connections
For each amplifier channel there are female and male XLR input connectors which are
wired in parallel. Typically the female connector is used for the audio input, the male XLR
connector being available to link the same audio signal to another amplifier channel.
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 screen of the input
cable should always be connected to one of these points to ensure that EMC performance
and regulations are met. The cable shield ground should also be connected to the source
device which is providing the input signal to the amplifiers.
