Sennheiser MKE 80 R Bedienungsanleitung Seite 7

Connection with battery operation
The handgrip/powering module is low-impedance
and balanced.
Load impedance: min. 300 Q (switch 3 in position I)
max.5 kQ (switch 3 in position II or 1'1)
Wiring see lig. 5.
ConnE!ction and operation at phantom-powered
microphone inputs or phantom-powering units
The microphone can be phantom-powered with DC-voltages
between 12. , . 48 V. Fig. 6 shows the basic Clrcuit diagram lor
phantom powering with 48 V.

Important note:
Should the microphone malnly be used with battery supply and
seldom with phantom powering, the battery can remain in the
handgrip/powering module during phantom powering. It will
not be drained. I1the microphone is exclusively phantom
powered the battery should be replaced by the battery dummy
MZD 3 included. Do not operate the mlcrophone with empty
battery compartment.

Using the microphone
The MKE 80 R has a high sound directlonality, i,e. it primanly
picks up sound sources which are directly In Iront 01the micro-
phone (Iig. 4), Therelore, the mlcrophone should be directed in
direction to the sound source.

Roll-off filter
For reducing interferences caused by (Ior example) lootlall,
wind or handling noise the handgrip/powering module leatures
a 3-positlon switchable roll off lilter. Position II brings about a roll
off 01 7 dB and position 1'1 a reduction 0120 dB at 50 Hz (Iig. 1).
In position I the lilter IS sWltched off, thus ensunng a Ilat
Irequency response, However, the roll off lilter reduces not only
Interfering noise, but also causes a reduction 01 part 01 the
otherwise useable low Irequency range, Therelore, the roll off
Illter should be used only I1interfenng noises cannot be ellmi-
nated by other means, For outdoor recording and close miking
the use 01the wlndscreen MZW 415 IS recommended In order
to effectively suppress avoldable interference without activating
the roll off lilter.
Mounting
The quick release clamp MZO 100 is supplied with every mlcro-
phone enabllng it to be mounted on all tripods, desk stands
etc, wlth a SIg", Y / or %" thread (Iig. 2). Further accessories are
Iisted under the appropriately headed chapter.
