Set as high as possible without hearing distortion.

Start with the control fully clockwise and play your loudest note or chord. If you hear distortion, lower the
trim with a small slotted screwdriver until the distortion goes away.

The Trim control can also be used to set the baseline levels for the Microphone and Transducer
Channels. If there is a disparity between the microphone and pickup levels, use the Trim control to
attenuate one channel (usually the Transducer Channel). Try setting the Trim controls this way ...

Set the Output Level to 3:00.

Set both Channel volumes to 12:00.

Play a note or chord on your instrument and lower the Transducer Channel Trim control until both

levels are equal, or are balanced to suit your taste.

Push in this switch to reduce microphone feedback.

Push in this switch to roll off excessive boominess in the Microphone Channel, especially for guitar.

Normally set the volume at around 12:00 (see Trim instructions below).   

These shelving style tone controls provide basic equalization for the Transducer Channel. Set them at
12:00 for no cut or boost (flat).

Set as high as possible without hearing distortion.

Start with the control fully clockwise and play your loudest note or chord. If you hear distortion, lower the
trim with a small slotted screwdriver until the distortion goes away.

Prevent feedback and match up the pickup and microphone signals for a stronger sounding amplified
signal.
