REAR PANEL

1. POWEr

– this rocker switch will illuminate with a soft amber color when the amp is turned on and ready to play.

A. AC LINE IN

– this plug accept a standard CLASS 1 IEC grounded cable (included) to provide AC power to the amplifier.

B. VOLTAGE SELECTOR

– used to select the input voltage level to 110/115V or 220/230V. Voltage standards vary by country. This

switch is preset at the factory. Setting the power supply voltage switch to the incorrect input voltage could damage the

power supply and possibly other parts of your equipment.

2. DIRECT OUTPUT

a. PRE/POST EQ Switch

– This switch determines if your direct output signal will be effected by the front panel equalization

settings. In the PRE setting, the direct signal is not effected by the front panel settings; in POST setting, the direct signal

is effected by the EQ settings.

b. DIRECT OUTPUT LEVEL

– this adjusts the overall level of the direct output.

c. DIRECT OUTPUT

– connect a standard XLR balanced cable from this jack to provide a line-level signal to your PA system,

powered speaker, or other powered output device.

d. GROUND LIFT

– this switch disconnects pin 1 on the XLR jack, which is connected to the shield in the cable and acts as

the ground point of the circuit, reducing ground-related noise.

3. EFFECTS LOOP

– these ¼" unbalanced send and returns allow you to run external effects before the preamp, resulting in

clearer effects signal, and cleaner levels (line level vs. instrument level). Connect the Send to your effect devices input,

and the output from your device to the return. Use the LEFT return for MONO effects. Connect the Send to your effect

devices input, and the output from your device to the return.
