Fishman powerjack and Martin Active Jack—Rev. 2.3:
1. Remove the "000" jumper from the endpin preamp.
2. Thread cable assembly through barrel and solder as indicated.
preamp Module Installation
1. Locate the module flush with the edge of the soundhole,
on the bass side. Center the module between the transverse
brace and the bass-side x-brace (figure 1).
Figure 1.
2. Sand off any lacquer and/or buffing compound from the
inside edge of the soundhole. Then, clean this surface with
rubbing alcohol. Let dry.
Note: For the strongest bond we recommend you now
apply a water-based primer/sealer to the bare wood inside
the soundhole. Let the primer/sealer dry before continuing.
3. Peel back the release film on the bottom of the preamp
module and fasten the preamp to the underside of the sound-
hole. The adhesive gains maximum hold after 24 hours.
4. You may separate the control module from the magnetic
base for better access inside the guitar. To separate the
module, locate the tab on the right edge of the unit and push
it down, toward the back of the instrument. Once you feel the
magnet let go, swing the module towards the center of the
soundhole, then separate the left-side magnet.
5. Secure the wires to the side of the guitar with the included
adhesive backed clips and cable tie (figure 1).
Microphone positioning
You can position the microphone to find the "sweet spot"
inside the instrument. Take the time to experiment with
microphone placement until you find the position that works
best in the instrument.
Plug in the guitar and move the blend slider to the left for mic
only. Start with the mic capsule so that it faces the back of the
guitar. Move the mic closer to the sound hole for more bass.
Turn the capsule toward the sides of the instrument for
less bass (figure 2).

Microphone Trim Control
A small circular potentiometer is recessed below the volume
slider and can be accessed with a small slotted screwdriver.
This is a "set it and forget it" control. Use it to calibrate the
microphone balance in relation to the pickup. Set the Blend
slider to the center position and adjust the trim control until
both the microphone and pickup levels are balanced to
your liking (figure 3).
