Main output (speech reinforcement) calibration is
strange.
Was the volume changed by any
method other than the
MAS-A100 gain after calibration?
Was sound heard during test
signal output or during
calibration?
Is Dante routing for Main output
incorrect?
Is the volume of the speech
reinforcement amplifier too low?
Is the reverberation or reflection
too loud?
Were the surroundings quiet
during calibration?
Is the volume of the speech
reinforcement amplifier
appropriate?
Is there a continuous sound at
constant volume emitted during
calibration?
Yes
No

After calibration, adjust the volume using the
Gain setting of the MAS-A100. If adjusted
using any other method, calibrate the
MAS-A100 again.
(See “4.4 Audio design” (page 30))
Check whether the Rec output is being speech
reinforced.
(See “4.4 Audio design” (page 30))
Use a test sound and configure so that the
sound can be heard.
(See “Calibration preparation” (page 63))
Use a test sound and configure so that the
sound can be heard with appropriate volume.
(See “Calibration preparation” (page 63))
Install sound absorbing material so that
reverberation and reflection do not occur.
(See “Installation environment for speech
reinforcement” (page 19))
Do not chat or make other noise during
calibration.
(See “Calibrating” (page 64))
The status changes to “Poor” if the volume is
too high. Changes to “Excellent” when too
low, but the speech reinforcement volume will
be low.
(See “Calibrating” (page 64))
Check that the PA system does not include
some non-linear processing or dynamic
processing.
