AUDIO CONNECTIONS
Use commercial RCA cables to wire the 2-track inputs and outputs.
You can also connect unbalanced devices to the balanced input/outputs. Use either mono plugs, or use
stereo plugs to link the ring and shaft (or pins 1&3 in the case of XLR connectors).
CAUTION! You must never use unbalanced XLR connectors (PIN 1 and 3 connected) at the MIC input
jacks if you want to use the phantom power supply.
