Power the Acoustic Attack - continued
Installing the Battery
Install a standard 9‑volt battery by removing the battery door and attaching the battery to the
terminal connector. Fit the battery into the compartment and reinstall the battery door.
Using an AC/DC Power Adapter
You can power the Acoustic Attack using the optional AC006 power supply available from your
local Hartke dealer. Simply plug the power adapter into the DC inlet and then, plug the power
adapter into a standard 110‑volt power outlet.
Control Knobs and Switches
Before you get started you should get familiar with the various control knobs and switches on
the Acoustic Attack and how they operate. The BASS, MID and TREBLE, as well as the MIX con‑
trols, are activated by the ON/OFF switch and are engaged when the red LED is illuminated.
Using the Equalizer
The BASS, MID and TREBLE knobs are used to adjust the overall tone of your acoustic guitar.
These equalizer controls are active when the footswitch is set to "ON" indicated by the illumi‑
nated red LED. When the equalizer controls are set to the “5” position they are set flat and have
no effect on the sound. If you want to add more lows or highs to your sound, move the BASS
or TREBLE control knobs up, and if you want less low or highs move the respective knob down.
The MID control works in conjunction
with the FREQ control, which selects
the mid‑range center frequency. You
can sweep the mid range control from
170 Hz to 4 kHz. Use your ears and
experiment with these knobs to get
the sound that’s best for your music.
A good place to start is with the BASS,
MID and TREBLE control set to “5” and
then make small changes and listen to
the difference.
