U 89 i
This characteristic is achieved without resort-
ing to corrective resonance effects.
Delivery Range
The capsule it is elastically mounted to avoid
any structure borne noise that could interfere
with its operation.

With a self noise level of 17 dB (A-weighted)
the total dynamic range is
117 dB. Maximum sound pres-
sure level is 140 dB when the
–6 dB rotary switch is in the
ON position.

A low frequency roll-off at
80 Hz or 160 Hz can be acti-
vated with the third rotary
switch below the headgrille.
This filter suppresses low frequency interfer-
ence, yet maintains an even frequency response
for close-up sound sources, for
example, when proximity ef-
fect could adversely affect the
program material.

A complete survey and detailed descriptions of all
accessories are contained in the accessories
catalog.
Meaning of color codes:
blk = black, ni = nickel
A steep high-pass filter in the
LIN position prevents the out-
put transformer of the micro-
phone from being overloaded
due to undesired subsonic frequencies.
Application Hints
• A microphone for universal usage
Operational safety
• Use as spot mic for
- wind instruments,
- strings,
All exposed surfaces of the microphone cap-
sule, including the diaphragms, are at ground
potential. This technology makes them highly
immune to electrical and atmospheric interfer-
ence and contamination through microscopic
dust particles.
- piano
These are just some of the most common applica-
tions. We recommend additional experimentation
to gain maximum use from this microphone.
