4.2.1 Audio connections
Please use commercial RCA cables to wire the 2-track inputs and outputs.
You can, of course, also connect unbalanced devices to the balanced input/
outputs. Use either mono plugs, or ensure that ring and sleeve are bridged inside
the stereo plug (or pins 1 & 3 in the case of XLR connectors).
◊ Caution! You must never use unbalanced XLR connectors (pin 1 and
3 connected) on the MIC inputs if you intend to use the phantom
power supply.
