External Phantom Powering
All micraphone
combinations
with the powering modules K 3 N and
K 3 -U m~y be phantom powered with voltages between 12. . .48 V
fram extern al power supplies. The ON/OFF-switch
has to remain
in the position "ON" when the microphone
is phantom powered
since the switch otherwise also disconnects
the audio output. The
battery, in these cases, is not used up. If for any reason the ex-
ternal power supply fails the micraphone
remains in operation if a
battery has been inserted.
The principle of phantom powering for 48 V and the powering
module K 3 N is shown in figA.
Pie ase note: The feed resistors have
to have different values for other voltages than 48 V (e.g. 680 f! at
12 V supply).

Low-cut Filter
The powering modules K 3 N and K 3-U have a switchable low-
cut filter with three positions to attenuate interfering low frequencies.
In position 1the filter is switched off and the two positions 11and 111
attenuate low frequency
interferences
corresponding
with the
,
characteristics
shown in fig. 5. This filter thus effectively reduces
wind noise, foot steps and handling noise. When recording outdoors
and also for close miking applications a suitable wind screen e. g.
MZW 30, MZW 201 and the MZW 415 resp. should be used in
order to first of all reduce avoidable interferences.
If the low-cut
filter is inserted it, of course, also attenuates part of the otherwise
use~ble low-frequency
range. Filters of that type should be always
usetJ intelligently
and with discretion.
It is always recommended
to
check your recordings e.g. with headphones
du ring the recording
process in order to avoid disappointments.

cables
Sennheiser
electronic offers a multitude of different connection
cables for your modular micraphone
system. The correct connection
cable for your tape recorder may be easily found in our "Mikrofon-
Anschluß-Fibel".
To connect these micraphones
to sound film
cameras
a "Camera-Anschluß-Fibel"
may be obtained through your
dealer, the Sennheiser
representation
in your country or directly

mentioned
are free of charge.
Mounting the Microphones
The micraphones are supplied
with a quick release clamp
MZG
104-1. This clamp pro-
vides mounting of the micro-
phone on standard 3/8" tripod
threads. Two cable
stands are
available as optional accessor-
ies to which the clamp may be
alternatively mounted. The
MZT 104 is a light collapsable
plastic desk stand and the
MZT 105-1 is asolid metal
studio-type desk stand.
