Locking XLR Power

The external power supply connects with a locking connector for reliable power.

Remote Foot Switch

Input connection for the optional JR2 footswitch or JR2 DT desktop dual function remote controls. The AB switch is used to select between the A and B inputs on channel-1 along with linked channels. The MUTE switch is used to turn off all outputs except the front panel headphone and tuner (monitor) outs.

2

Master Output

Left and right XLR-male outputs are fed from the bus. When used in stereo, channels 1 & 3 are routed left, while channels 2 & 4 are routed right. Top-mounted mono-sum switch sends all channels to both outputs.

3

1/4" Outputs

Dual hi-Z guitar amp outputs are transformer isolated to eliminate hum and buzz caused by ground loops. The top ¼” jack produces a summed mono output when the bottom jack is not in use.

4

Channel 1-4 Inputs

Balanced XLR-F A and B inputs accept mic or line levels. Front panel trim control is used to match their levels.

5

Channel 1-4 Outputs

Balanced XLR-M outputs are transformer isolated to eliminate hum and buzz caused by ground loops.
