914
914
The cardioid 914 is a pre-polarised condenser
microphone designed for demanding applications which
require a wide frequency response, high sound pressure
level, fast transient response and a compact design. With
its frequency response of 20 Hz to 20 kHz, the
able to capture the full sound of the instrument, while its
cardioid pick-up pattern isolates the microphone from
other on-stage signals.
An excellent microphone for cymbals and hi-hat, the
914 is also an ideal choice for precussion, woodwind
and string instruments.
Its excellent acoustic properties also make it a valuable
tool for home recording, the project studio and live stereo
pair recording.

Sensitivity and bass filter
The 914 is equipped with a three-position sensitivity
switch (A) and a bass filter switch (B).

Adjusting the sensitivity (A)
The microphone sensitvity can remain unchanged (0) or
be reduced by 10
when there is a risk that the microphone or subsequent
microphone input is overmodulated, e.g. due to high
sound pressure levels from drums, brass instruments, etc.
Note:
We recommend that you mute the corresponding
microphone channel on the mixing console before
connecting and disconnecting the microphone cable,
switching on and off the phantom powering or setting
the switches (see figure above).

Adjusting the bass filter (B)
The 914 has been designed for an extended lowfrequency bass response. With certain live or close
instrument miking applications, an over-emphasis of the
low frequencies can occur. This can be compensated for
by the 6
low-frequency wind noise by 18
dB/octave roll-off filter. The cut-off filter reduces
dB/octave.

Positioning the microphone
Percussion
Position Commentary
Positioning the microphone a few
centimetres above the outer edge of the
hi-hat aiming down gives a natural, clear
sound.
If necessary, remove unwanted lowfrequency signal portions by high pass
filtering.
Attention: When closing the hi-hat, a strong
air current is created on the edge. If the
microphone is positioned too close to the
edge, interfering noise due to the air current
can occur.
Good starting position for live miking
applications. If the overhead microphones
are only used for picking up the cymbals,
unwanted signal portions can be attenuated
by high pass filtering.
In order to prevent interference due to crosstalk between
adjacent sound sources, try to position the microphone so
that the interfering sound source is located in the angle
area of the highest cancellation of the microphone
(approx. 180°, see polar diagram).
