Making the Connections
• When using an AC adaptor, be sure to use only the specified type (PSA series; sold
separately).
Using an adaptor other than the specified type may cause the unit to malfunction, or
cause damage to the unit.
• To prevent malfunction and/or damage to speakers or other devices, always turn
down the volume and turn off the power to all devices before making any connections.
• 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.
• 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.
• The INPUT A/MONO jack doubles as a power switch. Inserting a plug in the INPUT
A/MONO jack turns on the power; the power is switched off when the plug is
disconnected. Be sure to unplug the cable from this jack when the RE-20 is not in use.
• 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

• 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 POWER indicator will become dim when
battery power gets too low. Replace the batteries as soon as possible.
• This unit is equipped with a protection circuit. A brief interval (a few seconds) after power-
up is required before the unit will operate normally.
