A. Treble: Use to add or subtract the highest frequencies or "presence".

B. Bass: Use to add or subtract the lower frequencies, add "warmth" or to cut

feedback.

C. Trim: The Trim Control is a moveable 12dB/octave low cut filter that is

adjustable from 27Hz to 200Hz. This filter customizes the effect of the bass

control and makes it possible to boost the low end in the warmth region

without adding excessive low bass. It is also useful to tame excessive low end

from mini-mics and dance club sub-woofers.

D. Volume Control: Unlike gain, whose adjustment will affect the character and

personality of the sound, the volume simply controls the amount of the signal

that gets out of the box. The Gigpro will likely be the quietest thing in your

signal chain. So for the best system signal to noise ratio, we recommend that

you run the volume as high as you can without causing the P.A. to distort.

E. 1/4” Output: This is a regular unbalanced output for a standard mono cable.

You can plug this into just about anything.

F. Invert: This control changes the polarity of the signal. When the button is

out, the output will be in phase with the input signal. Phase affects the way

the guitar top is pressurized by the speakers. When the guitar top and speaker

are out of phase with each other, low-end feedback will occur.

G. Battery Status LED: The battery status LED remains on at all times when the

unit is plugged in. As the battery weakens the light will gradually dim. When it

becomes difficult to see, replace the battery.

H. Battery Compartment: To change your battery, remove the two screws

adjacent to the belt clip using a screwdriver or a dime. Slide the preamp out

of the housing and replace the battery.

I. Phantom Power Switch: If you are using a mini-mic that requires phantom power, open the Gigpro as described above. The phantom power

switch is adjacent to the input jack. Caution: Do not use phantom power with anything other than a mini-mic or a device that specifically requires

it. Damage may occur!

J. Gain Control: See below.

K. 1/4” Input: This is a regular unbalanced input for a standard mono cable.

Gain is not volume. Gain is the amount of amplification that is applied to an input signal to boost it to a useful level. To accomodate a wide range

of pickups, active devices and such, the Gigpro has adjustable gain. The idea is to adjust the gain to find a window between hiss and distortion.

For instance, if you are using a low output passive pickup such as the Ribbon Transducer, and you fail to turn the gain way up, you will need to

turn the PA up so high to hear the pickup that there will be a lot of hiss. Conversely, if you plug in a high output active pickup and do not turn the
