Making the Connections
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.
Use a cable from Roland to make the connection. If using some other make of
connection cable, please note the following precautions.
Some connection cables contain resistors. Do not use cables that incorporate
resistors for connecting to this unit. The use of such cables can cause the sound
level to be extremely low, or impossible to hear. For information on cable
specifications, contact the manufacturer of the cable.
When the unit is running on battery power, the power comes on when you insert
the connector plug into the INPUT R (MONO) jack.
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, 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 unit’s indicator will become dim when
battery power gets too low. Replace the battery as soon as possible.
Turn on the power before you connect headphones. When turning off the power,
first unplug the headphones, then switch off the power.
Please observe due caution when using headphones while the LEVEL switch is set
to +4 dBu, since their volume may get significantly higher.
