MR5™ Using & Applications

The following page describes how to use the MR5™. For more information feel free to download the manual by clicking the icon at left.


The Radial MR5™ is a translator that takes the MIDI data output from a controller and converts the commands through the MR5 to a Radial device that employs the JR5 footswitch.

Making connections

Connect the MIDI output from your MIDI controller or pedal board to the input of the MR5 using a standard 5-pin MIDI cable. Additional MIDI devices can be daisy-chained via the MR5's MIDI THRU connector.

Connect the MR5 XLR outputs to the JR5 inputs of the Radial JX44, JX42 or any other product that employs a JR5 footswitch. The MR5 is equipped with dedicated XLR outputs for both 'Amps' and 'Guitars'. No power is required, as the MR5 will derive its power from the Radial device that you are controlling.

If you wish to use a JR5 footswitch in conjunction with the MR5, simply connect one of its XLR jacks to the MR5 and the other to the JR5 input on your Radial device. The pedal will now be in-line with the MR5, and your Radial device will respond to commands from both.

Not only can the MR5 be used to control both JX44 and the JX42, the MR5 can also be used in conjunction with the JR5 remote control. This allows a musician to still have their stage remote and have the MR5 send control messages to the JX44 or JX42 from a midi sequencer, or MIDI control pedals, or MIDI playback, from a MIDI track from back ground orchestration software. This allows for incredible flexibility for live performances to not just replace the JR5 remote as an option, but to augment and add extra functionality to a full JR5 - JX44 - JX42 system.

MIDI setup

The MR5's MIDI channel selection and configuration is set via the 8 DIP switches on the side panel. It can be setup to respond to an individual MIDI channel (1-16), or put into OMNI mode to respond to messages sent on all MIDI channels simultaneously. Once each switch is set to its desired position, push the SAVE/RESET button on the side panel to set the configuration as the changes will not take affect until you do so. DIP switch details can be found in the manual.


OMNI Mode allows the MR5 to respond to control and program changes on any MIDI channel (1-16). Setting the MR5 to a specific channel is particularly useful when linking multiple MIDI devices as they can all be set to only respond to changes on their assigned channel. Some MIDI equipment will default to OMNI mode when first switched on, so it is important to check configurations upon power-up and re-select the channel on your device if necessary.


The side panel is equipped with LED indicators to show you the status of the MR5. The power LED indicates that the MR5 is receiving power from your Radial device from the JR5 connection. The STATUS LED illuminates when a midi signal is being transmitted to the MR5. The MIDI indicator shows when a midi device is connected to the MR5.
