Guitar and Amp Switcher.
The Radial JX42, a compact switcher that is used to matrix four guitars and two amps in the studio or on a live stage
Starting with the front panel, the four (4) input channels feature 'radio-style' on-off 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. Switching is done using opto-resistive couplers that ramp up and down the signal, eliminating any popping that could otherwise occur. This is particularly important when mating the JX42 with high gain amps and concert-level PA systems. Inside, Radial's award-winning 100% discrete class-A buffering circuit is employed to ensure absolute signal quality is maintained. Each input channel also sports a dual function 'set and forget' potentiometer that can be assigned as either a level control to match various active or passive guitar or bass signals, or can be set to Drag for precise load correction when using passive magnetic pickups. Drag control replicates the tone and feel as if connected directly to a guitar amp. The potentiometers are recessed in order to leave the front panel clear of obstructions so that they are not accidentally changed during a busy concert.
Made from 14 gauge steel, this compact switcher begins with Radial's trademark bookend design. This creates a protective zone around the switches and knobs to 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 JX42s to be rack-mounted in a single 19" rack space.
