to reduce refl ections from the rings tensioning
the diaphragm.
The resulting frequency responses of the D-01 mi-
crophone are very fl at and smooth for all 15 avail-
able polar patterns.
In the upper formant range above 3 kHz the cap-
sule is more sensitive by approximately 2 dB. This
ensures a fresh, open sound character without
coloration.
The K 07 operates with an especially small dis-
tance between diaphragms and electrodes. This
provides for an effi cient, purely acoustical damp-
ing of the system. As the microphone character-
istics are obtained without resorting to correc-
tive resonance eff ects, the impulse response of
the microphone is excellent, and it transmits all
transient signals in music and speech without any
coloration.
The capsule is mounted elastically to attenuate
vibration noise. Since the frequency response of
the D-01 is linear down to below 20 Hz, even very
low frequency signals can be transmitted without
coloration. However this implies that the micro-
phone is also sensitive to low frequency noise sig-
nals such as structure-borne, pop and wind noise.
To avoid interference it is therefore advisable to
use the microphone low cut fi lter (see Section 4.2
"Software Functions") and/or to use a PS 20 a pop
screen or a WS 47 windscreen (see Section 7 "Ac-
cessories").
The directional characteristic of the capsule can
be set to any of 15 polar patterns via RCS-soft-
ware, allowing a particularly fi ne adjustment of
the microphone to recording conditions.
The 3-pin XLR output of the microphone is confi g-
ured according to AES 42-2001 and is mechani-
cally compatible with the similar connections of
analog microphones. This has the advantage of
allowing analog microphone cables to be used for
runs of up to approximately 100 m. Over-voltage
protection prevents damage to the D-01 in the
event that it is inadvertently connected to a phan-
tom-powered analog microphone input.
The microphone features exceptionally clean
sound transmission which is free of coloration,
with very low self-noise and an extensive dynamic
range. Digitization is performed by an A/D con-
version process developed and patented by Neu-
mann. This ensures that the full dynamic range
of the capsule signal is transferred to the digital
domain. The integrated digital signal processing
also provides functions which were previously
available only via a mixing console or additional
studio equipment. These functions are described
in the "Technical data" section.
If there is no microphone input according to
AES 42 standard available Neumann provides the
two-channel Digital Microphone Interface (DMI-2)
with the accompanying RCS control software for
remote controlling all microphone characteristics
(see also the "Technical data" section).
4. Setup
Mounting the microphone
Attach the microphone to a stable, sturdy stand.
Use an elastic suspension, if necessary, for the
mechanical suppression of structure-borne noise.
For this purpose set the microphone into the inner
cage from above, and secure it to the inner cage
with the threaded nut. If required, use a wind-
screen or popscreen from our range of accesso-
ries in order to suppress wind or pop noise.
Connecting the microphone
Caution: An incorrect supply voltage can dama-
ge the microphone!
Connect the microphone to microphone inputs
and to equipment which supplies phantom pow-
er in accordance with AES 42. See also chapter
"Safety Instructions".
Caution: Very high signal levels can damage
loudspeakers and your hearing!
Reduce the volume of connected playback equip-
ment before connecting the microphone. This is
also advisable in order to avoid acoustic feed-
back.
Connect the microphone by means of an XLR cable
to the AES 42 microphone input of the DMI-2 Digi-
tal Microphone Interface (see also DMI-2 and RCS
manuals) or to other audio equipment complying
with the AES 42 standard.
With a correct power supply, a blue LED on the mi-
crophone indicates that the microphone is ready
to operate. After switching on, the LED at fi rst
glows dimly, and after a short time shines with
the preset brightness. When the DMI-2 Digital Mi-
crophone Interface is used with the Remote Con-
