GROUND/LIFT SWITCH

The "Ground/Lift" switch affects the XLR jacks only, and affects both at once. Most often the "Ground"

position is correct. With the switch in the "Ground" position, the ground to pin 1 is engaged. In case of

excessive ground noise (most likely caused by a non-standard wiring of an XLR connection at a mixing

console), use the "Lift" position. Moving the switch to the "Lift" position will interrupt or defeat the

ground on pin 1. Pin out for the XLR jacks on the Mini-Mo' Preamp are as follows:

Pin 1 = ground

Pin 2 = positive

Pin 3 = negative

If a persistent hum exists after trying both positions of the ground lift, there is probably:

1. a bad cable or connection somewhere between your Balanced Output jack and the snake leading

to the mixing console

2. a dirty or miswired A/C socket

3. miswired or poorly wired A/C in the building

4. fluorescent lighting directly above you or in close proximity (especially when using single-coil pick

ups)

5. a cell phone in your right pocket that's interacting with the electronics in your bass (don't laugh,

this actually happens!)

But, in the case of a true ground loop, this switch can often times solve the problem.

3-POSITION PAD SWITCHES

As mentioned above, each XLR jack has its own independent switch for padding the signal if necessary.

The center position is 0 dB, the left position is -10dB and the right position is -20dB. Front-of-house

engineers and mixing consoles usually like to see -10dB, but some will take up to -20dB and others

can take unity gain (0 dB). Make the choice that best suits your needs.

HOW DUAL MODE AFFECTS THE INTERFACE PANEL

The Interface section allows a player the ability to send the same type of signal(s) to an external source

(mixing board, extra power amp, etc.) as to his own speaker cabinets. Since "Dual Mode" splits the

signal into a "clean" and "wet" channel, we've taken extra steps to ensure the widest variety of routing

two or more signals. So, with that in mind, here's how engaging "Dual Mode" affects the various

functions:

UNBALANCED PRE-MASTER OUTS IN DUAL MODE

TUNER OUT

Totally unaffected.

DIRECT OUT

With the "Line/Direct" switch in the "Direct" position, it is unaffected. With the "Line/Direct" switch in the

"Line" position, the signal sees the entire "Preamp" section, including the EQ, but NO ONBOARD

EFFECTS. In short, the "Dual Mode" switch changes the function of this jack when the "Line/Direct"

switch is set in the "Line" position.

MO' BASS OUT

Totally unaffected. It sees everything, just as before. So, if you want to run in "Dual Mode" and get the

"clean" preamp sound on one output and the "wet" onboard effects on the other, simply set the

"Line/Direct" switch to "Line", and use the "Direct Out" for the clean side and the "Mini-Mo' Preamp Out"

for the wet side.
