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.

For operation with voltages 01 less than 48 V, the supply voltage resistors in the supply device must lirst be changed over to the values listes in the table below.

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.

microphone input

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 1'1a 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.
