A More Compact JX "V2" in the Radial Line, Designed for Stage and Studio
The JX42-V2 follows the logic of switchers and reamping tools used as a "secret weapon" in production: you record a clean track, then send it back to a guitar or bass amp to re-explore the sound afterward, with the microphones, placements, amps, and effects of your choice. This version is presented as a more compact alternative to the JX44-V2, while retaining the essentials: a quality audio path, reliable switching, and a transformer-isolated output to handle configurations sensitive to ground loops.In practice, the JX42-V2 becomes a routing hub: it organizes your instruments, secures your signal thanks to its Class A buffer, and lets you switch from one amp to another without constantly unplugging. All with a "V2" approach focused on efficiency: direct front access, output selection, and easy rack integration.
Who the JX42-V2 Is For: Guitarists, Bassists, Keyboardists, and Sound Engineers
The Radial JX42-V2 targets both demanding musicians and technicians: guitarists and bassists who alternate multiple instruments in the same set, studios wanting to speed up takes, and FOH/monitor engineers seeking clean and repeatable switching. It's also ideal for modern "pedalboard + rack" setups: you centralize inputs, distribute to two amps, and maintain consistent control levels from one instrument to another.On the production side, reamping changes the workflow: you can focus on performance during recording, then fine-tune the tonal color afterward. Moving a mic, testing another cabinet, comparing two amps, adding an effects chain-the JX42-V2 naturally fits into this method by facilitating signal routing and level management.

Questions frequently asked
How many instruments can be connected to the Radial JX42-V2?
Four jack inputs allow connecting up to four sources. Each channel features a thru-out output, while outputs A/B send the signal to two amps.
Is output B isolated to prevent hum?
Output B includes a Jensen transformer providing galvanic isolation. This setup helps reduce ground loops when using two amps.
Can the impedance be adjusted for a passive pickup guitar?
A variable input impedance from 22 kOhms to 500 kOhms is available with a switchable impedance correction. The active circuit is based on a class A BiFET amplifier.
How to switch between amp outputs A and B?
The A/B selection is done via a front-panel switch. An optional Radial JR2 footswitch allows remote foot switching.
What size and power supply are required?
The unit occupies 1 rack space and measures 149 x 114 x 47 mm, weighing 1.05 kg. An external 15 V DC power supply is required. The stated frequency response ranges from 20 Hz to 20 kHz.
