4.2  Audio connections

You will need a large number of cables for different applications. The illustrations 

below show how the connectors should be wired. Be sure to use only 

high-grade cables.
Please use commercial RCA cables to connect the 2-Track inputs and outputs.
You can, of course, also connect unbalanced equipment to the balanced inputs/

outputs. To do this, use either mono plugs or stereo plugs with the ring and 

sleeve bridged (pins 1 and 3 in the case of XLR connectors).

◊ 

Caution! Never use unbalanced XLR connectors (PIN 1 and 3 connected) 
on the MIC input connectors when using the phantom power supply.
