Transducer
Rear Panel
Switches
Power
The rear panel Power switch activates the Transducer, confi rmed by the lighted blue front
panel LED.
Voltage
The rear panel voltage selector switch serves to let the user switch to the local line voltage
standard.
IMPORTANT ADVICE: Before you use the Transducer, make sure that this switch setting
refl ects the correct local power line voltage (115V position: 110-120V, 230 V position: 220-
240V).
Ground Lift
The rear panel GND lift switch eliminates hum by separating the internal ground from the
unit’s housing ground. Hum can, for example, result when this unit’s housing has a common
ground connection with other machines that might have a different ground potential.
Phase
Applies to Line Output 2 only. This switch reverses the signal phase by 180° to prevent
frequency cancellations when another machine is connected.
Phase reverse is applied for example to compensate for different phases from a cabinet
(connected via Speaker Thru) and a monitor in a live setup or to compensate for phase differ-
ences from two guitar amps in a studio setup.
