JX42 | Buy Radial Engineering direct from Singapore's Authorized Distributor for warranty assurance.
The JX42 from Radial is a compact guitar and amp switcher made to handle up to four guitars and two amps simultaneously. Designed for concert touring, the JX42 is equipped with four radio-style switches that immediately turn the previous channel off when the new channel is selected. These are complemented with LEDs for visual feedback on dark stages. To ensure quiet switching, opto-resistive couplers are employed to eliminate popping that may otherwise occur.
Inside, the JX42's 100% discrete class-A buffering circuit is designed to ensure that high fidelity is maintained. Each input channel also sports a recessed dual-function potentiometer that can be assigned as either a level control to match wireless systems, or be set to Drag control for precise load correction when using passive magnetic pickups.
There are two main stage amp outputs, with the B-output transformer isolated to eliminate hum and buzz caused by ground loops. Amp selection occurs via a front-panel AB selector or by connecting the optional JR2 remote footswitch. These features make the JX42 an ideal choice for stages and studios alike.
