In-ear monitors require a full seal of
the ear canal for full bass response.
A poor seal also reduces hearing
protection and can enable acoustic
feedback. The Audio Seal Test was
developed by Sensaphonics to help
users ensure proper t and full seal.
During the test you will hear two
alternating tones, one at 50 Hz and
the other at 500Hz, each played at
the same volume.
THE AUDIO SEAL TEST
If you have any doubts about your
fit, use the Audio Seal Test to
confirm that your IEMs are fully
sealed.
Note: If the earpieces are inserte
with the bodypack already
switched on (not recommended),
a brief feedback squeal may occ
until the earpieces are fully seale
For this reason, a safety limiter
is engaged when the bodypack
is rst switched on,limiting the
level of any possible feedback
to its default setting (84 dB-SPL).
Pressing either the + or - switch o
the top of the mixer pack release
the safety limiter and restores yo
stored limiter threshold settings.
To access, tap the
‘Seal Test button (ear)
found in the upper
right of the ASI Audio
app screen
If the ear canals are properly sealed, both
tones will be clearly audible.
If the earpiece is not properly sealed, the
50 Hz tone will be much lower in volume,
or even inaudible.
