Radial JX44™ and JR5™In Detail
 

The Radial JX44 is the most powerful amplifier and guitar switcher made today. Take some time here to familliarise yourself with it's features and you will see the potential for simplifying your stage setup, making instrument changes a breeze and effortlessly switching and combining amps on the fly!


JR5 Remote Footswitch

The optional Radial JR5 remote footswitch is specifically designed to control and make full use of the JX44's advanced programmable architecture. Housed in a rugged 'Radial-tough' 14-guage enclosure, the JR5's five heavy-duty momentary contact switches remotely trigger electronic routing of guitar and amp signals within the JX44. The JR5 automatically configures itself to control switching of either instruments or amplifiers.

The JR5 can be configured for 'manual', 'bank' or 'programming' modes with one footswitch press. Programmability is provided on the footswitch itself so selecting up to four different combinations amps or 'scenes' can be accomplished easily, without a walk back to the equipment rack. The six on-board LED indicators provide a visual aid to programming the footswitch and show you the current status for each of the four switching 'scenes' as well as, the MUTE status and footswitch connection to the JX44. Left and right XLR connctors are provided to make optimal placement on stage or pedalboard easy.

SGI-44 Studio Guitar Interface for JX44

The Radial SGI-44 studio guitar interface provides a convenient long haul interface that will drive a guitar signal up to 300 feet (100meters) to a pedalboard or remote effects without the signal degradation usually associated with long cables runs.

Desiged primarily for use with the JX44, the SGI-44 functions similarly to the stand-alone Radial SGI interface 'TX' transmit and 'RX' receive modules but incorporated into the same chassis for use with the built-in SGI interface of the JX44. The SGI44 also emplys premium Jensen™ transformers of the ultimate in ultra-low noise performance.

The SGI-44 lso equiped with a Radial's unique Drag™ control load correction is provided at the input -- this makes it easy to plug in to the SGI in the studio control room and play through amps up to 300 feet away, perhaps in a differnt room (or building!) without loss of tone or addition of noise or buzz.

A buffered tuner output lets you have access to tuning without the tuner adding noise or degrading your guitar signal.
