PART I - PREPARATION Cont’d.
PREAMP CUT-OUT
For guitars with
1.Choose the preamp location on the side of the instrument.
Note that the bezel has the ability to conform to most curved sur- faces on standard size guitars.
2.Tape the enclosed Cutout Template to the desired location.
Use the flex shaft tool (with 1/2" blade) or the router (with 1/4" cut- ter) to make the
3.Drill the screw mounting holes using the 1/8" drill.
PART II - INSTALLATION
a complete stop before removing it from the hole.
SOLDER THE WIRE CONNECTIONS
1. Insert the pickup in the sad- dle slot then strip and tin the wire ends.
2. Solder the "hot" wire from the pickup (inner conductor) to the pad marked "IN" on the preamp circuit board. Solder the "ground" wire from the pickup (shield) to the pad marked "GND" on the preamp circuit board.
3. Strip and tin the wire ends of the preamp output cable. Solder the RED wire to TIP, the BLACK wire to RING and the ground wire to the SLEEVE of the 1/4" jack.
MOUNT THE PREAMP
The hardware supplied will accommodate guitars with laminated sides that are between .100" and .175" thick. If your guitar has sides less than .100" thick, the slider knobs will not fit in the bezel properly.
To make up the difference, use
1.Fasten the 3/16" brass hex screws and the 1/4" hex standoffs to the preamp as shown. Note that the mounting holes on the volume control side of the circuit board are slotted to allow for fitting the preamp to the curved surface of the guitar side.
2.Temporarily fit the preamp and bezel together on the guitar, with the standoffs finger tight. Fasten the bezel with the
3.Mount the backplate to the preamp with the 3/16"
4.Plug the guitar into an amplifier and set all the slider's tone con- trols to their center positions. On the back of the preamp, there is a recessed
5.
6.Attach the adhesive backed plastic wire guides to the sides or the kerfing of the instrument.
7.Insert a 9 Volt Alkaline battery into the battery clip.
IMPORTANT: Although the supplied battery holder should provide adequate capacity to grip the battery at all times, we strongly recom- mend removal of the battery when shipping your instrument. FAILURE TO REMOVE BATTERY COULD RESULT IN DAMAGE TO YOUR INSTRUMENT. Fishman will not be held responsible for any such dam- age as a result of shipping or handling.
OPERATION
The output jack of the Acoustic Matrix Professional System is also the power switch for the battery.
When a cable is first plugged into this jack, the BATT/LOW LED will flash momentarily to indicate that the power is on.
When the battery power is low, this light will remain lit.
Be sure to unplug the output jack when not in use
to avoid battery drain.
Adjust the volume of the preamp and your amplifier as desired. Using your ears as a guide, set the PHASE switch for proper phase relationship with the sound source (amps, monitors, etc.).
This relationship is most audible at louder volumes and will change from room to room and with your position on stage.

PREPARE THE ENDPIN BLOCK
TOOLS
• Masking Tape | • |
• Variable Speed Drill | • Center Punch |
• 1/8" Twist Drill | • 15/32" Spade Bit Drill |
• 1/2" Open End Wrench | • 3/32" Allen Wrench |
The objective of this method is to drill a hole in the endblock, with the endpin in place. You may remove a loose endpin and refasten it in the endblock with cyanoacrylate glue before starting this procedure.
1.Apply masking tape around the endblock area to protect the instru- ment.
2.Locate an
3.Centerpunch a guide hole in the center of the trimmed endpin.
4.Drill a 1/8" pilot hole through the endblock.
5.Line up a 15/32" Spade bit in the pilot hole and begin drilling. Maintain a perpendicular plunge in relation to the instrument. Use steady (but not heavy) pressure, especially as the drill exits inside the guitar.
IMPORTANT: To avoid damage to the instrument, let the drill come to
FASTEN THE JACK IN THE ENDPIN HOLE
Follow this sequence when installing the endpin jack:
1 - Shielding Cap (optional)
2 - First Large Hex Nut
3 - Large Dress Washer
4 - Star Washer
5 - Guitar Endblock
6 - Small Dress Washer
7 - Small Dress Nut
8 -
Strap Button
The jack should protrude at least 5/16" and no more than 11/32" out- side of the body for proper fit. After fitting the small dress washer and nut over the end of the jack, insert the 3/32" allen wrench through the cross drilled hole on the end of the jack. Tighten the nut with the 1/2" open end wrench while holding the jack in place with the allen wrench. Thread and hand tighten the the strap button.
NOTE: With the strap button in place, the end of the jack should protrude slightly to allow proper plug fit.
