buster. If you can hear both signals loud and clear
you can fix the cable with the cable clamps.
7. Soundhole Control and Final Assembly
Depending upon the construction of the guitar,
you may find it necessary to use different materi-
als to underlay or pad the soundhole control. First
dry-fit the control unit to determine the position.
If adhesive tape is used, make sure to degrease
both surfaces. Position the SHC where you can
reach it easily and fix the cable in a safe position.
With the guitar in playing position, the right pot
(in the direction of the bridge) should be the
master volume, the left pot (in the direction of the
neck) adds the microphone signal.
Now, after degreasing the position of the
cable clamps, fix these to the side of the
guitar and secure the cables to avoid unwanted
rattling noises. String up your guitar and bring the
instrument up to pitch.
That should be it!
8. Operation
The AK15 plus is a very powerful system, which
combines a strong piezo signal with an additional
microphone signal. It is designed to blend the
microphone to the pickup for overtones and
more liveliness.
The mic does not work alone!
You can make use of the whole range of the SHC
microphone control to almost maximum, de-
pending on your personal sound preferences.
The volume control adjusts your overall output
signal. Starting in zero position (no output signal,
over to far left), turn it clockwise to boost the out-
put level, but please regard: the optimal range of
this control is between 30 and 60% rotation! Full
volume is neither necessary nor recommended.
Adding the microphone volume will yield a more
natural and lively sound. Too much microphone
signal can cause feedback, lower the microphone
volume if this occurs.
Plugging the jack into the endpin-socket closes
the circuit and switches the system on. Without
jackplug the system is switched off and there is no
active battery consumption, just the usual self-dis-
charge of unused batteries.
10. Troubleshooting
No piezo signal
Make sure you have connected the jack connector
properly. There should be an audible „click“ when
the ball-ended jack safely sits in the 2.5 mm plug.
It may take a little effort.
No mic signal
Too much or too little mic signal
The microphone master level is pre-adjustable
independently at the preamp and controlled with
the soundhole control (master added
microphone level). If you have trouble dialing in
the right amount of microphone signal, if you
feel there is too much microphone signal, or not
nearly enough, we have a solution for that. Inside
the preamp we have a small potentiometer with
which you can increase or decrease the master-
volume for the mic signal. This is a very delicate
invasion, hence the placement inside the pre-
amp, please use this very carefully. If you have so
much mic signal that you can’t use the soundhole
control to get the right amount in the mix, or if the
soundhole control is fully open and you still could
use more mic signal is the only time to use this
internal control.
No output signal
Ensure that the battery still has enough charge
to operate the system. The indicator light on the
soundhole control unit will light if the battery has
low power. If the battery has no power at all, this
light will eventually dim.
Ensure that the strap holder on the endpin is
screwed on tightly. Strap movements some-
times loosen the strap holder which may lead
to a contact fault in the endpin socket. There
are aftermarket solutions with straplocks for
acoustic guitars that may prevent this.
Uneven balance
Attention to proper string balance is a normal
issue with all pickup systems – more or less
obvious – depending e.g. on the dynamic range
of the systems.
Just listen to your instrument as it is without
pickup and play each individual string one after
the other with the same impulse. You may find
that the natural reproduction of the strings
is already uneven. Just one example of many
reasons for uneven reproduction.
