Inputs
Buffered gold-contact inputs for unbalanced instruments such as guitars and basses. The front panel jacks take priority over the rear panel instrument inputs.
On/Off
Large switches with green LED indicators turn each instrument input on/off. Multiple inputs can be on simultaneously.
Tuner Out
Buffered unbalanced output to feed a tuner pedal. This output is fed by all inactive instrument inputs, and can be used simultaneously with the rear panel Tuner output.
Amp Select
Illuminated switch toggles between amp outputs A & B. The light for the amp select switch turns off when the Mute function is engaged on the optional JR-2 remote footswitch or via MIDI commands. Each amp output also features a corresponding LED which turns on to indicate which amp output is currently active.
IEC Power
Connection for standard IEC power cable.120V/240V operation for international use.
MIDI In
Standard 5-pin MIDI connector allows MIDI controllers to activate the inputs and outputs of the JX42 V2. Eight dip switches configure channel, program, and control changes. Can be used in conjunction with the JR-5 and the JR-2 remotes.
JR-5 Remote
XLR connection for the optional JR-5 remote footswitch, which can control the instrument inputs from a distance.
JR-2 Remote
1/4” TRS input for connection to the optional JR-2 remote footswitch, which can toggle between or mute the amplifier outputs. When a JR-2 remote is connected, the front panel amp select switch on the JX42 will be inactive.
Tuner Out
Buffered unbalanced output to feed a separate tuner. This output is fed by all inactive instrument inputs and is always on. Can be used simultaneously with the front panel Tuner output.
Outputs
Transformer isolated and buffered gold-contact outputs for feeding two stage amplifiers.
Lift
Isolates the ground connection on each amplifier output to help eliminate hum and buzz caused by ground loops.
Inputs
Buffered gold-contact connections for unbalanced instruments such as guitars and basses. Wired in parallel with front panel connectors.
