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

reflects 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.
