USER'S GUIDE

1 . Q U I C K S T A R T

1. Install the battery

2. Locate the "Internal Controls" diagram in section three to use as a reference.

3. If either of your sources require phantom power, turn it on now.

4. Plug a three-foot stereo cable into the guitar and into the Mixpro's input.

5. Plug a mono cable from the Mixpro into the PA or amp.

6. Pan the mix control completely to the first channel and set the gain and EQ.

7. Pan the mix control fully to the second channel and carefully set the gain so

that it is about as loud as the first channel.

8. Adjust the low cut to work with your second source's EQ settings.

9. Fine-tune the gain again to match the second source's volume with the first

source.

10. Turn the mix control to 12:00 and try both positions of the relative phase

switch to find the best phase for your combination. If you can't decide, choose

the relative phase that provides the smoothest pan.

A. Treble control: Use to add or subtract the highest frequencies, also known as

"presence."

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

feedback.

C. Trim control: The trim control is a movable 12dB/octave 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 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 Mixpro 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 PA 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 in

phase with each other, low-end feedback can 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. Mix control: This control allows you to blend the two inputs to suit your taste

or application. As you face the control, full counter-clockwise (left) will give

100% of whatever pickup you have placed on the tip. Full clockwise will give you

100% of the ring.

J. Input: This input will accept a 1/4" stereo cable. You can also use a standard

mono cable if you just want one pickup or do not have a stereo cable (there will
