Radial Engineering JX-42 Guitar and Amp Switcher

The Radial JX-42 is a compact guitar and amp switcher made to handle up to four guitars and two amps simultaneously.

Designed for concert touring, the JX-42 begins with four radio-style switches that immediately turn the previous channel off when the new channel is selected. These are complimented with easy-to-see LEDs for visual feedback on dark stages. To ensure the quietest switching possible, opto-resistive couplers are employed that ramp up and down the signal, eliminating any popping that could otherwise occur. This is particularly important when using the JX-42 with high gain amps. Connecting the optional JR5 footswitch enables remote control over input channels.

Inside, Radial's award-winning 100% discrete class-A buffering circuit ensures absolute fidelity is maintained. Each input channel also sports a recessed dual-function 'set and forget' potentiometer that can be assigned as either a level control to match wireless systems or be set to Drag™ for precise load correction when using magnetic pickups. Drag Control replicates the tone and feel as if connected directly to a guitar amp. There are two main stage amp outputs. These are transformer isolated to eliminate hum and buzz caused by ground loops. Selecting the amps may be done using a front panel AB selector switch or by connecting the optional JR2 remote footswitch via a TRS jack. Adding the JR2 footswitch also lets you mute the amps for quiet on-stage tuning.

Made from 15 gauge steel, the JX-42 follows Radial's trademark bookend design to create a protective zone around the switches and knobs and safeguard against the harsh environment of professional touring. The unique I-Beam construction adds tremendous rigidity to protect the internal circuit board from torque which could lead to premature cold solder joints. Optional rack ears allow one or two JX-42s to be rack-mounted in a single 19" rack space.
