JR•1™
ACTIVE MODE
On the rear panel you will find a switch labeled ACTIVE/PASSIVE. This is
recessed to prevent accidentally changing settings during use. Use a small
screwdriver to access the ACTIVE/PASSIVE switcher during setup. Once
you are done, you will likely leave it alone.
Set the switch to ‘active’ (inward position) when the JR•1 is controlling a
Radial device such as the Relay Xo stereo switcher. When set to active, the
JR•1 sources its power from the remote device and the LED indicators work.
PASSIVE MODE
A passive mode may be engaged that allows the JR•1 to function as a
standard footswitch for any device with a compatible ¼" footswitch jack. Use
passive mode with non-Radial devices such as guitar amplifiers to change
amp channels or electronic keyboard to turn on the sustain. Note that some
Radial devices can be operated using the JR•1 but they are not able to
provide power to the LEDs, in this case passive mode should also be used.
To use like a standard footswitch, set the ACTIVE/PASSIVE switch to
‘passive’ (outward position). The A/B status LEDs will not illuminate when the
JR•1 is operating in passive mode. Connection is done the same way with
¼" guitar cable. Connect one end to the JR•1 and the other to a compatible
footswitch jack.

REVERSING THE LEDS
In order to have the LED indicators line up with the channels of your connected
Radial device, the JR•1 includes a switch on the rear panel labeled LED REV.
This switch will reverse the A and B LED indicators so that they are illuminated
with the corresponding inputs or outputs on your Radial device. If you connect
your JR•1 and the LED indicators already match the ones on your Radial device,
simply leave this switch in the ‘out’ position. Note that the LED REV switch only
affects the JR•1 when it is used in Active Mode as described above.
