Batteries
When using the Hexpander alone there is no need for a battery. The units is
always powered from the external device plugged in to the 13-pin connector.
When using the Hexpander with an Acousti-Phonic pre-amp, battery life is
somewhat less than for an Acousti-Phonic pre-amp on its own; about 150 hours
of continuous use. However, battery power is only used when a plug is inserted
in the stereo jack. When the instrument is used with an external device plugged
in to the 13-pin connector (such as a MIDI converter), power is drawn from the
external device.
This means that most players should get many months of usage from a single
battery. However, we recommend replacing the battery every six months as a
precaution. The Acousti-Phonic pre-amp and Hexpander are designed for use
with a single nine volt battery. Higher voltages will damage the units 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 pre-amp turns on.
Remember to unplug the cable from the stereo jack when you are nished
playing to avoid draining the battery.
