Input 2 will either be the Jack on the front, or the red Phono on the back of the unit.

The Jack is used to Instrument (e.g. guitar or bass) or mic-level inputs.

The Phono is used for Line level inputs (e.g. synthesiser or mixer output).

Ensure that the input 2 switch is in the correct position for your chosen input source.

For stereo Line inputs, ensure that both input 1 and input 2 switches are in the Line position.
