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 816P48 U3
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 1mV.
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.
