Acoustic Image Flex - Manual (Page 10)

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.
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.
Mounting Options
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.
