JX44 Guitar Signal Manager
Concert Touring Guitar & Amp Signal Manager
The Radial JX44?
is a guitar signal manager and switcher designed for the most demanding professional concert stages where wireless guitar systems, acoustics, effects and multiple amplifiers are used simultaneously.
Select between up to 4 guitars and 6 amps
Programmable with optional JR5 footswitch
Built in DI box, SGI line driver and X-Amp Reamper
Transformer isolated to eliminate ground loops
The ultimate guitar signal manager
The JX44 is the most complete guitar and amp switching and routing system available for professional concert touring, providing
you with the ability to connect and manage up to four guitars, six amplifiers, an effects chain and a remote pedalboard with seamless integration throughout. Optional JR-5 remote footswitches can be used to select the inputs and outputs individually or to
program and recall scenes to activate multiple amplifiers with a single footswitch. A local effects loop can be used to connect rackmount signal processors, and an SGI line driver is built-in to feed distant pedalboards with ease when used with the SGI-44
remote guitar interface. An assignable direct box output is also featured, and the JX44 can be used to reamp balanced line-level signals, with front panel status indicators to provide an easy systems check at a glance.
JX44 Specifications
The Radial JX44 is a combination guitar input selector, signal distribution amplifier, effects router, direct box and Reamper.
With so many ins and outs, it is somewhat difficult to break down the specifications as each of these functions serve a purpose on their own. Given the fact that the JX44 combines 5 devices at once, for the live touring tech the single most significant spec
may well be noise. The JX44 does an exemplary job at keeping noise levels down.
