player or another balanced line level source.

• AUX 2 (line level input - unbalanced)

• AUX 3 (line level input - unbalanced)

• AUX 4 (line level input - unbalanced)

• AV
For use within an audio visual (AV) system - gain is xed at X1,
meaning the input and output levels are the same at all times.
WARNING: Do not use with any other source or damage may occur
to equipment.

• TAPE IN
