Hearing protection
The
AC 06
features a hearing protection function which reduces
the volume of the headphones in case of sudden, loud noises. If
the noise gets even louder, the headphones will be switched off.
Once the source of the noise goes quiet, the
AC 06
recommences
its work. The hearing protection function prevents the ears from
being exposed to excessive acoustic pressure.

pears when the hearing protec-
tion function is activated.
Sensitive
The hearing protection function activates at a low (quiet) thresh
-
old.
Average
The hearing protection function activates at a moderate threshold
(default setting).
Insensitive
The hearing protection function activates at a high (loud) thresh
-
old.
CAUTION!
Only use SEWERIN
headphones, as these are
specially designed for the
AC 06
.
Note:
The hearing protection function should only be set
to “sensitive” for quiet ambient sounds so that it
activates with moderate noise. In situations where
loud ambient noise is common, the threshold should
be set to “average”. In exceptional circumstances
the threshold can be set to “insensitive”. The hear
-
ing protection function is only activated at very loud
noise values. To prevent the
hearing protection
function from activating very frequently
and thus
making leak detection more difficult,
the headphone
volume
and the basic amplification
should not be
set too high
!
