Looking closely at the circuit board in the vicinity of the jumpers, you

can see that each has a label that tells you the option that has been

selected by the jumper. The Gain Jumper is labeled "Norm" or "-6 dB."

If the shunt is under "Norm," the normal gain option is selected. The

Filter Jumper is labeled "Invert" or "LP." If the shunt is under "LP," the

low pass filter, or speaker emulator has been selected. As you can

see, each channel has the jumper option, so you can select the same

or a different option for each one. The Ch 2 Jumper is labeled "Out" or

"In." If the "In" position is selected, channel 2 is disconnected from the

output buss and is connected to the Ch 2 Preamp Out jack on the rear

panel. (Hopefully that nomenclature is not too confusing.)

Once you have made the jumper selections you want, reinstall the

preamp panel in the chassis.

Mounting Options

The Flex Pre can be mounted just about anywhere that puts it where

you want it. It will attach magnetically to the top of the Flex Cab. Simply

position the front feet on the bottom of the chassis in the recessed

holes in the top of the Flex Cab and the magnets will hold it in place. It

will sit on a table top or it can be mounted on a mic stand with the

included adapter. An available mounting bracket (On-Stage Stand

MY550--available from Sweetwater.com) will allow you to mount the

unit on the side of a music stand or mic stand.

Note that there are powerful magnets in the vicinity of the

recessed screws in the top of the Flex Cab. Do not place anything

on the top that will be damaged by the high magnetic field. Smart

phones, tablets, laptops, digital recorders, etc. should not be

placed on the top of the cabinet.
