Connections
* Inserting a plug into the GUITAR IN or BASS IN Jack will automatically switch the unit on.
* The use of an AC adaptor is recommended as the unit’s power consumption is relatively high.
Should you prefer to use batteries, please use the alkaline type.
* Noise may be produced if wireless communications devices, such as cell phones, are operated in the
vicinity of this unit. Such noise could occur when receiving or initiating a call, or while
conversing. Should you experience such problems, you should relocate such wireless devices so they
are at a greater distance from this unit, or switch them off.
* 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 are batteries in the unit while an AC adaptor is being used, normal operation will continue
should the line voltage be interrupted (power blackout or power cord disconnection).
* Once the connections have been completed (p. 8), 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.

* 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 unit’s indicator will become dim when battery power
gets too low. Replace the battery as soon as possible.
