Attaching the MZA 900 P to clothing
Using the belt clip, you can unobtrusively attach the
MZA 900 P to clothing (e.g. belt, waistband).
Switchable pre-attenuation
The gain can be reduced by
12 dB. This is recommended
when the subsequent micro-
phone input is overmodulated
or when the MZA 900 P’s
output is strongly biassed by
the subsequent device, e.g. due
to high sound pressure levels
from drums, brass instruments, etc.
Please note that when operating the MZA 900 P on 12V
phantom powering, its output is considerably biassed by
the power supply. If this is the case, and when high sound
pressure levels occur, the pre-attenuation should also be
switched on.
Switchable roll-off filter
The roll-off filter allows the MZA 900 P to be adapted to
Sennheiser HSP and clip-on microphones. With the roll-
off filter switched on (
), the low-frequency signal
portions (below 125 Hz) are attenuated, thus increasing
speech intelligibility. In addition, pop and wind noise is
effectively suppressed.
