GUITAR AND AMP DISTRO

The Radial JX44 is a feature packed 4x4 guitar and amp signal management tool designed
to provide the concert touring guitarist with a means to control wired and wireless guitars,
and distribute the signal to multiple amplifi ers with footswitch control. It incorporates two
effects loops for rack processors and pedalboards, a dedicated tuner output and footswitch­able mute for silent tuning. A built-in Radial ProDI direct box distributes the signal to the P A
or recording system and may be assigned to all guitar inputs or input-D exclusively.

Superb audio quality is accomplished using Radial’s acclaimed 100% discreet class-A
circuit topology with Drag Control load correction. Noise is eliminated with the use of trans­former isolation on all of the amp outputs. The JX44 is augmented with a built-in Radial X­Amp re-reamplifi ng interface for driving amps from a recording system in post production.

The JR5 remote footswitch and SGI-44 remote pedalboad interface connect to the main unit
using standard balanced mic cables up to 100 meters (300ft.) long.
