JX-42 Guitar and Amp Switcher
4x2 Guitar and Amp Switcher
The JX-42? is a compact guitar and amp switcher made to handle up to four guitars and two amps, with the ability to select inputs and outputs locally or via remote footswitch control.
Select between 4 guitars and 2 amps
Individual input trims & Drag Control load correction
Remote footswitch control with optional JR-2 and JR-5 switches
Transformer isolated to eliminate ground loops
Compact switching solution
The JX-42 is a surprisingly powerful guitar and amp control center, small enough to fit on top of your amp, but able to switch between up to four guitars and two amplifiers without noise. Each input is equipped with a trim control to level-match input signals, or a Drag control load correction circuit to optimize the impedance presented to magnetic pickups for a more natural tone. Optional JR-5 and JR-2 footswitches can be connected for instant switching available right at your feet, allowing the JX-42 to be rack mounted off-stage when used with wireless systems.
JX-42 Specifications
The Radial JX-42 is an unbalanced instrument switcher designed to work best when working employing signal levels between -30dBu and 0dBu. Looking at the specifications and associated graphs, the JX-42 demonstrates a linear frequency response and minimal phase shift across the intended range which indicates that it will perform admirably well with both guitars and basses. The low noise floor, minimal crosstalk, adjustable level controls and optical switching will assure quiet performance and low switching noise even when used with high-gain guitar amps.
