2.OVERVIEW AND CAUTIONS

The Dual Source is designed to support most acoustic guitar pickups and popular mini-microphones. If this unit was purchased as the Dual

Source System, it will include our Ribbon Transducer and Dual Source mic. No soldering will be needed. If you purchased only the preamp,

connectors are provided for the mic and pickup. Do not use the mic channel for a second pickup.

We recommend that this system be installed by a professional dealer/installer. We do not provide installation advice or support for home or

hobbyist installations. Installers: please read the instructions carefully before proceeding. We will not be responsible for any damage to the guitar

or personal injury resulting from installation, improper installation, use or misuse of the product.

3.INSTALLATION

1. Strapjack installation: Drill a 1/2" hole in the tail block using a step drill.

Cover the area you are drilling with masking tape to protect the finish.

Remove the strap ring, retaining nut and one washer from the end of the jack.

There should still be one star locking washer, one flat washer and a nut

remaining on the mid section of the jack. Bring the jack down into the sound

hole and through your pre-drilled hole in the tail block. Using the internal nut

(be sure to include the flat and star washers), set the proper depth that will

allow the smaller threaded section at the end of the jack to protrude out of

the end of the guitar. When the jack is fully seated in the tailblock, there

should be about 2 threads of the small threaded section remaining inside the

hole. With the jack in place, lay the remaining washer over the threads and

attach the external retaining nut until it's tight. Finish by attaching the strap

button (it should cover the retaining nut and washer) carefully so as to not

crack the finish of the guitar by asserting too much pressure.

2. Pickup installation: Install the pickup at this time by following the

instructions provided with the pickup. If you are using any pickup other than

the Ribbon Transducer, attach the mini-plug (provided) to the pickup wire

after it has been installed. The pickup wire should be long enough to reach

through the sound hole to facilitate the soldering. Cover the top of the guitar

to protect it. Remove the black threaded barrel from the plug and slide it over

the wire with the threaded section facing the end of the wire; forgetting to do

this may cause severe headaches. Now solder the hot wire (the inner part of

the coax) into the small, tube-shaped area in the center of the plug. Bend the

ground tabs around the shield wire and solder the shield wire to them. Clip

the excess shield wire, and firmly screw the barrel onto the plug.

3. Microphone setup: This system is engineered for the Dual Source mic, but

will support most other popular internal mini guitar mics with the standard

two-wire connection. If you are installing a mic other than the Dual Source mic, consult the mic owner's manual for the proper connection. Attach

the connector to the wire at this time as follows:

A: The Dual Source Preamp kit provides two small metal crimp pins and a brown plastic connector for the mic. Crimp the signal wire in one of the

pins (refer to your mic's manual to identify the wires), and the ground and shield wires together in the other one, as shown in figure 2.

B: Now slip the crimped wires into the brown connector so they snap into place. The signal wire needs to go into the side marked with a "1" (see

figure 2). The preamp provides nine volts on the signal (pos.) pin for the mic, making phantom power from an outside source unnecessary. Set the

mic aside at this time and continue with step 4. Placement of the mic will be completed later, after the preamp is installed.

4. Remote Control setup: The Remote Control Module consists of a black circuit board and the anodized aluminum top plate forming two halves of

a clamp that mounts on the top edge of the soundhole. Connect the ribbon cable (provided) to the ZIF (zero insertion force) socket connec-tor on

the bottom side of the remote module in the same manner as shown in figure 3.

Just before you mount the preamp, plug in the output jack, pickup, mic and ribbon cable for the Remote Control to their receptacles on the circuit board.

gain position as well. But, since you can't be absolutely certain, try it in both positions to see which one is right for your situation. C. A good starting point for the mic low cut knob is about 10:00, as shown on the Dual Source label. fig. 6 A B C D D. With the two knobs on the Remote Control turned all the way down, plug into your sound system with a standard mono cable and gradually bring up the volume on the Remote Control. This will give you the pickup signal only.

the pickup handle most of the low frequency duties. Pickups are usually less prone to boominess and feedback than microphones, so try setting the mic low cut to around 1000Hz (approximately 9:00), then boost the bass control on the P.A. The bass control will then have little effect on the mic but will add warmth to the mic without inducing feedback. The correct low frequency cut-off will also vary with the preferred mic phase and from venue to venue.
