General description
The MKH816 P 48 U 3 is a directional studio microphone with a
high directivityfactor. This is highly desirable in the film and TV
studio and also outdoorsfor multipleapplications.The microphone
employs the proven RF-principle for low noise, low interference
operation. Itis designed for 48 V phantom powering.
Features
. High directionality
. Low equivalent sound pressure level
. Rugged and extremely resistant to unfavourable climatic
conditions
. High sensitivity

XLR-3-11c XLR-3-12C,
Principle of high frequency circuit
The capsule of a RF condenser microphone represents contrary to
DC circuits a low impedance. Instead of the high polarisation
voltage normally required, the capsule requires only a high fre-
quency voltage of about 10 volts, which is produced bya built-in
low-noise oscillator (8 MHz). This principle ensures the micro-
phone's high operational reliability, particulary for outdoor
recordings in extreme climatic conditions.

Powering and connection
All Sennheiser microphones designated MKH . . . P 48 are 48 V
phantom-powered according to DIN 45596.
Either condenser- or dynamic microphones from Sennheiser
electronic employ the principle of voltage matching. This "no load
condition" has the advantage that neither impedance variations of
the microphone output nor of the amplifier input have a noticable
influence on the total perfomance of the system (e. g. frequency
response). The source impedance of Sennheiser condenser micro-
phones with phantom powering is extremely low (about 10 V at
1000 Hz) so that the amplifier input impedance has only at least
600 O. This is usual in the majority of cases. Should - however -
the input impedance be smaller than 6000, a resistor of appro-
priate value should be placed in series with the microphone so that
it "sees" at least 400 O. The voltage division caused by the series
resistor must, of course, be considered. The same method can
be used when higher output impedance of the microphone is
demanded. In this case again, aseries resistor can be used to
provide correct matching.
Sennheiser condenser microphones produce relatively high output
voltages exceeding 1volt at maximum sound pressure levels. This
has the advantage that even with long cables induced interference
signals can be disregarded. Also the internal noise produced by the
microphone does not contribute to the total noise level. The micro-
phones are fitted with RF filters which ensure that no high frequency
signals from the microphone can effect the external circuitry and
that the microphone itself is protected from high frequency distur-
bance. It is therefore not necessary, even under the most difficult
conditions, to take special precautions, such as double screening of
the cables or the provision of high frequency filters.

Senn heiser condenser microphones are polarised according to
DIN standard i. e. when apressure pulse strikes the capsule Irom
the lront, pin 2 goes positive with relerence to pin 3.
Connection to balanced,
floating microphone inputs
In this case the microphone is simply connected via apower sup-
ply, e. g. MZN 16 P 48, or powering adapter MZA 14 P 48 (see
accessories) to the inputs 01the amplilier.
Connection to unbalanced microphone inputs
IIthe microphone is powered bya corresponding supply unit and is
to be connected to unbalanced inputs it is generally necessary to
use a translormer. The secondary 01this audio-translormer may
then be connected - one side grounded - to the input Proper
voltage matching is achieved by selecting a suitable translormer
ratio. IIthe powering adapter MZA 14 P 48 or the power supply unit
MZN 16 P 48 is used a translormer is not required.
Connection to microphone inputs
with high sensitivity
IIthe amplilier being used has a very high input sensitivity, i. e.
when it is normally intended lor use with dynamic microphones, it
can be necessary to reduce the output voltage Irom the micro-
phone by means 01a voltage divider. This should be built into the
microphone cable at the amplilier input This way the large signal
on the microphone cable is maintained up to just belore the micro-
phone input, which helps to increase the signal to noise ratio.

:~:
MKH 816 P 48 U 3
Connection to mixers and sound recording
equipment with powering facilities
IIan d.c.voltage 0148V :t12 V is available the condenser micro-
phone can be powered directly (see also ligure "Powering and con-
nection"). The voltage should be stabilised and liltered, so that the
unweighted noise voltage is less than 1 mV.
According to the DIN standard the two leed resistors should be
approx. 6.8 kO. The difference between the two resistors should be
;;;;0.4 %. The current taken by Sennheiser condenser microphones
MKH . . . P48, is approx. 2 mA. This means approx. 7 volts are lost
ac ross the resistors.
