TRIM Control
The TRIM control is accessible through the hole located between the
INPUT A and INPUT B jacks. This control can be adjusted using a small
flat-bladed screwdriver or a #1 size Phillips head screwdriver. Its location
allows it to be adjusted using a long screwdriver through the soundhole
of the instrument, if you don’t wish to remove the electronics.
Like any regular volume control, it has mechanical stops at each
end of the rotation, so take care when adjusting not to try to force it
past its limits, or you will damage it.
The TRIM control affects the gain of the INPUT A preamplifier ONLY , so
it essentially acts as a balance control for the system. Turning the control
to the left (CCW) increases the gain of the INPUT A preamplifier, and
makes the Bass side Acoustic Lens louder in the mix. Turning the control
to the right (CW) decreases the gain of the INPUT A preamplifier, making
the INPUT B Acoustic Lens louder in the mix. Careful adjustment will
allow you to tune in the exact balance between the bass and treble
strings of your instrument. The adjustment range is typ/- 3dB,
wide enough to accommodate any desired balance. This is a “set and
forget“ type control, so once the proper balance is found, it will usually
not require any further adjustment.
