Input channels
The four balanced input channels can be accessed via 3-pin XLR sockets. These are labelled
"IN 1 - MIC/LINE" to "IN 4 - MIC/LINE". The input levels can be adjusted using the rotary
controls "IN 1 - MIC/LINE" to "IN 4 - MIC/LINE" on the front panel.
Between two XLR sockets there are 6-way DIP switches. This can be used to configure two
input channels in each case.
