Can I have any combination of guitar inputs active at the same time?
Yes, each input has an associated latching on/off switch, allowing you to turn on any combination or all four inputs at the same time. This makes it easy for guitar techs to perform instrument hand-offs on stage, where one guitar can continue to ring out while the other guitar is already active through the PA and ready to play.
Can I switch the inputs and outputs from my pedalboard?
Yes, input and output switching is available using the Radial JR-5 Remote Footswitch, or you can use a MIDI footswitch controller to operate many of the features on the JX42 V2.
How to I send signal to the tuner output?
The tuner output is automatically fed by any input 1-4 that is inactive, so a guitar tech can grab any instrument offstage and perform a quick tune-up. For example, if you have only instrument Input-1 turned on, then Input-2, 3, and 4 will all simultaneously feed the tuner out.
Can I use the front and rear panel tuner outputs simultaneously?
Yes, both tuner outputs will always be active and they can be used at the same time.
Can I connect microphones to the guitar inputs?
No, the JX42 inputs are designed for instrument-level signals only. For a four-input microphone selector, check out the Radial Gold Digger.
Can I connect keyboards or other instruments to the guitar inputs?
Yes, any unbalanced, instrument-level source can be connected to the JX42 V2. However, for managing multiple keyboard signals on stage, the Radial KL-8 may be a better solution as it is designed specifically for that purpose.
Is it possible to mute the outputs of the JX42?
The JX42 V2 does not have a dedicated mute switch, but if you are using the JR-2 remote footswitch to control the amp outputs then you can use the Mute switch on this device to silence outputs A and B from the JX42. Otherwise, you can mute all guitar inputs if using the JR-5 remote to control the JX42 inputs.
Can I have both amps A and B active at the same time?
No, the JX42 only allows one of the two amp outputs to be active at any given time. Should you require more than one amplifier active at a given time we recommend the JX44 V2.
Can I use the same power supply for the JX42 V2 when touring between multiple countries with different power grids?
The JX42 V2 comes with an internal switching 100/240V power supply for use when touring internationally. You’ll just need to swap out the IEC power cable for one that matches the connector type for each region.
When programming a MIDI footswitch should I use Control Change (CC) or Program Change (PC) messages?
It is better to use Control Change (CC) messages as you can typically assign two values to a single MIDI programmable footswitch allowing for on/off control of various JX42 V2 functions – please see page 9 of the owner’s manual for more details, and refer to your MIDI controller user guide on how this is implemented on your device.
