About the J8
Connections
Connecting the J8 to your Johnson Amp is very easy. Follow these steps when
connecting the J8 to the amplifier for the first time:
1. Begin with the power turned off on your amplifier.
2. Using the supplied 5-pin DIN cable, connect from the controller output jack on
the back of the J8 to the J8/J12 Foot Controller jack on the back of your
amplifier.
3. Power up the amplifier. With the Millennium series amplifiers, all that is needed
to do is move the expression pedal a few times and the J8 will be ready to use.
4. On the Marquis and Mirage series amplifiers, the J8 will enter a calibration
mode the first time it is connected. The display will briefly flash 1.X (software
version number) followed by
Pb.
5. Rock the J8's expression pedal back (toe up position) and press any footswitch.
6. The display will now read
PF. Rock the expression pedal forward (toe down
position) and press any foot switch.
**If Er appears in the display after step 6, wait until Pb appears in the display and
follow steps 5 and 6 again.
When the display returns to the current program number, the J8 is now calibrated
for your amplifier. This calibration routine will only need to be performed the first
time the J8 is connected to you amp. If for some reason your J8 fails to function,
consult you Marquis or Mirage User’s Guide for recalibration instructions.
Footswitches
The 8 footswitches on the J8 will access different functions in your Johnson
Amplifier. The functions are fixed and cannot be changed when used with the
Marquis and Mirage Series amps. These switches can be assigned to different
functions in the Millennium Series amps.
