AER AK15 plus User manual

Thank you for choosing the AK15 plus
pickup system.
Be assured, we have done a lot to achieve
this level of performance.
The AK15 plus is a two source system with
a piezo crystal plus an electret condenser
microphone integrated in the endpin. The
microphone level is adjustable at the preamp
and controlled with the soundhole control
(SHC).
The AK15 plus provides high volumes
and impressive punch combined with
low noise components for the best possible
signal to noise ratio.
Operation
The AK15 plus is a very powerful system,
that 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 AK15 plus
system is not made for“microphone only“
performance! You will nd a surprisingly
warm yet strong and clear tone from the
piezo due to a suitable electronic environ-
ment. The microphone will add denition,
vitality and authenticity as well as an “acous-
tic ambience“, that makes the sound more
natural.
Plugging your jack into the endpin-socket
closes the circuit and switches the system
on. Without jackplug the system is switched
o  and there is no active battery consump-
tion, just the usual self-discharge of unused
batteries.
With the guitar in playing position, the right
pot (in direction of the bridge) is the master
volume, the left pot (in direction of the neck)
adds the microphone signal.
You can make use of the whole range of
the SHC microphone control to almost
max (over to far left = no microphone
signal), depending on your personal sound
preferences.
The Master Volume control adjusts your
overall output signal. Starting in zero posi-
tion (no output signal, over to far left) turn
it clockwise to boost the output level, but
please keep in mind: the optimal range of
this control is between 30 and 60% rotation!
Full volume is neither necessary nor recom-
mended.

Troubleshooting
No piezo signal
Make sure that the jack connector
inside the guitar is connected properly.
There should be an audible“click“ when
the ball-ended jack safely sits in the 2.5
mm plug. It can take a little eort.
No mic signal
Please listen carefully rst as you may
just expect way more microphone than
we provide for good reasons and bare
in mind: in many cases the reference for
functionality is including the negative
bit… we are not proving this range as
we want to make sure that you can use
the microphone up to its best.
No output signal
Ensure that the battery still has enough
charge to operate the system
Ensure that the strap holder on the end-
pin is screwed on tightly. Strap move-
ments sometimes loosen the strap
holder (although the rubber O-ring
should prevent this) which may lead to
a contact fault in the endpin socket.

Plug-in endpin to the SHC: take care of the right
position. The little catch must be at the top side.
