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 con-
venient, 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 bat-
tery 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 opera-
tion. 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 disconnected, 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 speak-
er system and bass amp before un-plugging any mic cable with phantom power.
