Step 5: Turn up the headphone volume
(A plea from the JamHub inventor: Please be careful with your hearing. You’re going to want to keep play-
ing for a long, long time and you’ll want your ears in good working order.)
Step 3: Setting the trim levels
1. Use the double knob labeled “trim” to set your input gain (note: you don’t need to put on headphones to do this step).
Use the light under the dual trim knobs to set this knob to the right level for your inputs by follwing steps 2 and 3.
2. Speak into the mic and turn the outer/bottom knob up (clockwise) until the LED turns yellow. Then turn it back a little.
3. Play your instrument and turn the inner/top knob up (clockwise) until the LED turns yellow. Then turn it back a little.
4. Watch your trim settings throughout the jam session. Sometimes input levels can change as the band gets warmed up.
Use the table below as your guide.
In summary
Step 4: Pick a virtual location with the stage control
Left Brain:
Start with the headphone output control at zero
(100% counterclockwise) and slowly turn it up.
Because every section of the JamHub
®
has its own
individual mix, output adjustments will vary by player.
So start low and turn up slowly. Also, headphones have
a wide variety of impedances. While your JamHub is
designed to handle them all, the setting of each head-
phone volume knob might be different.
Right Brain:
Don’t burn out your ears. Bring the volume up
s-l-o-w-l-y. Also, while the JamHub does work with
most headphones, it can’t make cheap or poor quality
ones sound better. Sorry, we’re gear makers not miracle
workers.
Left Brain:
green = signal
yellow = near clipping (-6dB)
red = preamp clipping (+6dB)
Right Brain:
green = good
yellow/orange = caution
red = bad
Left Brain:
The stage control is simply a pan or balance control
that helps ensure that musicians don’t crowd the mix.
Because our hearing system has two receptors sepa-
rated by about 6 inches (known as your ears) we have
the ability to perceive sounds coming from different
locations due to slight delays in arrival time. Great audio
engineers have known for a long time that by “moving”
things to their own sonic location, our hearing system is
optimized and we experience greater clarity. There’s a
great article on Wikipedia about this amazing property
of our hearing system. Read all about it here:

Right Brain:
Does everyone in your band stand in the middle of the
stage when jamming? Of course not. So spread out
sonically with the Stage Control. The experience will be
similar to what happens when you’re playing live. You’ll
hear things with greater clarity and the jams will be
more enjoyable. If you want to understand why great
recordings have instruments panned to different
locations, read the “left brain” side of this box and
the article on Wikipedia mentioned over there. Learn-
ing to spread out sonically will help your band get ready
for the recording studio as well.
