2. Safety instructions
The microphone has the intended purpose of con-
verting acoustic signals into electrical signals.
Connect the microphone only to microphone in-
puts and devices which supply 48 V of phantom
power in accordance with IEC 61938.
Repairs and servicing are to be carried out only by
experienced, authorized service personnel. Un-
authorized opening or modification of the equip-
ment shall void the warranty.
Use the equipment only under the conditions
specified in the “Technical data” section. Allow
the equipment to adjust to the ambient temper-
ature before switching it on. Do not operate the
equipment if it has been damaged during trans-
port.
Always run cables in such a way that there is no
risk of tripping over them.
Unless required for operation, ensure that liquids
and electrically conductive objects are kept at a
safe distance from the equipment and its connec-
tions.
Do not use solvents or aggressive cleansers for
cleaning purposes.
Dispose of the equipment in accordance with the
regulations applicable to the respective country.
3. Brief description
The U 89 i is a condenser studio microphone with
a transformer output and the directional charac-
teristics omnidirectional, wide angle cardioid,
cardioid, hypercardioid and figure-8.
The microphone features exceptionally clean
sound transmission which is free of coloration.
A special feature of this large-diaphragm system
is its almost linear frequency response up to
10 kHz, throughout an incidence angle of 200°.
This permits neutral processing even of signals
originating from the side.
This feature is particularly important, for in-
stance, when the characteristics of the room are
to be treated as an integral aspect of the overall
sound.
A switchable high-pass filter increases the lower
cutoff frequency, thus reducing the influence of
the proximity effect and structure-borne sound.
The pre-attenuation switch reduces the micro-
phone sensitivity by 10 dB, thus allowing the pro-
cessing of very high sound pressure levels.
Typical applications of this versatile microphone
include use as a spot microphone, as well as the
recording of winds, strings and piano.
Special mention should be made of the suitability
for recording live concerts, when it is important
to obtain an accurate representation of the spatial
characteristics.
