You will need a large number of cables for dierent applications. The illustrations
below show how the connectors should be wired. Be sure to use only
high-gradecables.
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.
