STEP 9: Batteries
Battery life is about 500 hours of continuous use. While this means many months
for most players, we recommend replacing the battery every six months as a
precaution. The Acousti-Phonic Intelligent Pre-amp is designed for use with a
single nine volt battery. Higher voltages will damage the Acousti-Phonic Intel-
ligent Pre-amp and void the warranty.
Always make sure that your guitar amp is turned down or off before plugging a
cable into your instrument’s output jack. Failure to do so will cause a loud thump
as the Acousti-Phonic Intelligent Pre-amp turns on. Remember to unplug your
instrument when you are nished playing to avoid draining the battery.
The output of the mag and acoustic signals should be similar at identical volume
control settings. If they are not, the Acousti-Phonic Intelligent Pre-amp includes
a Gain pot which may be adjusted with a small screwdriver if necessary. NOTE:
Clockwise adjustment will increase output.
