Connections
* Inserting a connecting plug into the INPUT jack
turns on the power to the unit.
* Raise the amp volume only after turning on the
power to all connected devices.
* The use of an AC adaptor is recommended as the
unit’s power consumption is relatively high. Should
you prefer to use a battery, please use the alkaline
type.
* To prevent malfunction and/or damage to speakers
or other devices, always turn down the volume, and
turn off the power on all devices before making any
connections.
* If there is a battery in the unit while an AC adaptor
is being used, normal operation will continue
should the line voltage be interrupted due to power
blackout or power cord disconnection.
* Some connection cables contain resistors. When
connection cables with resistors are used, the sound
level may be extremely low, or impossible to hear.
For information on cable specifications, contact the
manufacturer of the cable.
* Once the connections have been completed, turn on
power to your various devices in the order specified.
By turning on devices in the wrong order, you risk
causing malfunction and/or damage to speakers and
other devices.
When powering up:
Turn on the power to your guitar amp last.
When powering down:
Turn off the power to your guitar amp first.
* Always make sure to have the volume level turned
down before switching on power. Even with the
volume all the way down, you may still hear some
sound when the power is switched on, but this is
normal, and does not indicate a malfunction.
* When operating on battery power only, the CHECK
indicator will become dim when battery power gets
too low. Replace the battery as soon as possible.
