Step 2: Connections
1. Plug in the power adapter. The blue LED light tells you when the JamHub
®
is ready.
2. Pick a section to call your own.
3. Plug in your instrument with a Stereo (TRS) cable using your instrument’s or amp’s headphone jack for the best
results. Often the headphone jack’s output is optimized for headphone listening.
4. Plug in a microphone.
5. Plug in your headphones.
6. Tell your band mates to follow steps 2 through 5.
7. OK, you’re almost ready to rock. But first some very important info:
IMPORTANT! Connect your instruments with a stereo instrument cable or stereo adapter!
When connecting your instrument, it’s important to use a stereo cable, here’s why. Your JamHub is a stereo environment,
just like the real world. Because your instrument’s output often includes reverb and other stereo effects, we designed the
JamHub to accept a stereo signal and make the listening experience great. If you connect to the JamHub with a mono
cable, like a standard guitar cable, your sound will be 100% in the left ear, this is because of the way a mono cable works
with a stereo jack.
You can use the included mono 1/4” female to stereo 1/4” male adapter if you need to use a mono cable. But we recom-
mend against using this solution in the long run. Audio coming from this “spit mono” signal is not as good as a stereo
signal. This is because of the way the human hearing system works. In a live jam, each ear hears something slightly
different because of reflections in the room. With “split mono” each ear hears the exact same thing and that reduces our
perception of clarity. Therefore “split mono” is not as optimal as a true stereo signal, so we recommend using a stereo
signal and a stereo cable.

Left Brain:
Turn all the knobs on the JamHub
®
to zero (100%
counterclockwise) to protect the device and your
headphones from grounding and connection pops.
Now that everyone’s connected, a good starting mix is
your control at 2:00 and every one else at 12:00.
Right Brain:
Protect your ears and your gear: turn all knobs down
on every section of the JamHub before putting on the
headphones. Okay, do this NOW.
Now that everyone’s connected a good starting mix is
your control at 2:00 and every one else at 12:00.
