The SEND jack can be used in mono and the RETURN jack in stereo. When using the RETURN jack, change the setting (stereo/mono) to match the input signal.
Perform the steps below:
- Turn off the power (unplug the cable from the INPUT A (MONO) jack).
- Set the type knob to “DIAMOND”.
- Turn the [AMBIENCE], [LEVEL] and [GAIN] knobs all the way counterclockwise, and turn the [BASS], [MIDDLE] and [TREBLE] knobs all the way clockwise.
- While holding down the pedal switch, turn on the power by inserting a plug into the INPUT A (MONO) jack.
After the CHECK indicator lights up green, it cycles between blinking orange four times and staying lit. - Use the type knob to select "TWN".
Select this when you have connected a stereo (TRS) plug to input a stereo signal. - Press the pedal switch.
This saves the settings.
Also, the CHECK indicator rapidly blinks red.
You can play normally with this unit after around two to three seconds.
