Operating the Bass Attack
Setting Up the BASS ATTACK
The basic procedure for setting up and using your Bass Attack is simple and takes only a
few minutes. Remove all packing materials (save them in case of need for future service).
Power the BASS ATTACK
You can power the Bass Attack with a standard 9-volt battery, a standard DC power
adapter, or by applying standard 48-volt phantom power. You can use which ever power
source is most convenient, however, you should keep in mind that there are, from time-
time, trade-offs. You may have a well grounded live sound or studio set-up that will not
exhibit ground loop problems, but when you are on the road or in other studios you can
have ground loops. Because of possible ground loops, which are part of live sound and
recording, you may want to consider using a battery to keep the grounds from the Bass
Attack isolated from the grounds the rest of your gear. You can check the phantom or AC
operation with a quick sound check to listen for any buzzing. If there is no buzz you have
a well-grounded system. If your hear buzzing, go to battery operation. Hey, life’s a trade
off, so is powering your audio gear.
PHANTOM ON - OFF / GROUND CONNECT / LIFT SWITCH
The PHANTOM ON -OFF / GROUND CONNECT / LIFT SWITCH is a latching switch that
provides two functions at the same time. In the up position, the switch connects Ground
on the XLR cable, and by doing that, the switch also allows the unit to be powered by a
phantom power supply. When the switch is set to the down position, the ground is discon-
nected, and therefore, the phantom power operation is disabled.
Using Phantom Power
If you are connecting to a mixer that has phantom power, the Bass Attack can be powered
by connecting a standard mic cable to the Direct Output. Be sure to check that the mixer’s
phantom power switch is set to the “on” position. Then, make sure that the PHANTOM ON
- OFF /GROUND CONNECT / LIFT SWITCH is out so that phantom power is enabled.
WARNING : To avoid a possible loud pop that can damage speakers, be sure to mute your
speaker system and bass amp before un-plugging any mic cable with phantom power.
