USING THE JDX 48
After making connections use your amp and speaker cab as normal and
set the amp volume to an appropriate level. Keep in mind that the output
level of the JDX 48 (at the balanced XLR) will follow changes to the
amp's volume so it’s best to set your amp up the way you like it before
setting levels at the mixing console.
When your amp is setup, turn up the preamp level at the mixing console.
If you notice hum or buzz caused by ground loops, try pushing the
GROUND LIFT switch inward. This will isolate the signal ground between
your amp the mixing console and eliminate the noise.
MIXING THE JDX 48 WITH A MICROPHONE
Combining the sound of a microphone with the JDX 48 can add greater
depth and ‘fatten’ your guitar tone. The JDX 48 and microphone signals
can be mixed together to create rich textures.
After connecting the JDX 48, place a microphone on your speaker cab and
connect it to an additional mixing console channel. Set the microphone's
preamp level and start mixing the sound from both channels together.

Amplifier
Try moving the microphone around the room to find the sweet spot where
the fundamental frequencies or harmonics line up to create a satisfying
tone from the two sources. You can also send the JDX 48 signal to the left
speaker and the mic signal to the right speaker to create a stereo effect.
