Thank you for choosing the AK

15 plus

pickup system.

Be assured, we have done a lot to achieve 
this level of performance. 
The 

AK

15 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 

AK

15 plus provides high volumes 

and impressive punch combined with 
low noise components for the best possible 
signal to noise ratio.

Operation

The 

AK

15 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 

AK

15 plus 

system is not made for “microphone only“ 
performance! You will fi nd a surprisingly 
warm yet strong and clear tone from the 
piezo due to a suitable electronic environ-
ment. The microphone will add defi 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 

off  

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.
