Step 8. Connect an audio source
The PROCASTER™ is fitted with a universal 3.5mm stereo input jack similar to I-pod™ and
modern car audio equipment. It has been designed to accept stereo left and right audio channels
and mixes them into a mono signal.

The built-in audio processor has a fairly wide accommodation range and will automatically adjust
audio level for optimum sound quality. In addition there is an input audio level adjustment control
(normally set at mid-point) accessible through the front panel using a small jewellers screwdriver.
The audio level can be set from approximately 200mV to 3V which will accommodate most audio
devices.
