In combination with a connected microphone, the transmitter can be used  
as a cordless microphone. Its flat shape and small dimensions make this  
design especially well - suited for particular applications in which an  
inconspicuous appearance is required, as is the case with film and  
television productions, for example. To reduce interference and to  
improve the signal-noise ratio, SK 50 and SK 250 transmitters are  
equipped with the "HiDyn plus" noise reduction system. In combination  
with a receiver which is also equipped with this system (e.g. EM 1046), a  
connection can be established, which is characterised by excellent  
operational reliability and supreme transmission quality.  
FEATURES:  
• Metal injection-moulded casing with quick-change energy pack  
• State-of-the-art PLL technology, 16 switchable channel  
• Sennheiser "HiDyn plus" compander  
• Signal-to-noise ratio > 108 dB (A)  
• Integratal voltage converter for constant output power  
through to complete discharge of the battery or rechargeable battery  
• Operating time display with blinking warning  
• Battery status transmission to the receiver  
• Operating and peak deviation indicator

3. MICROPHONE SELECTON  
The MKE 2-4, MKE 102-4 (omnidirectional polar pattern) and MKE 40-4  
(cardioid polar pattern) Lavalier chlip-on microphones are available. They  
are equipped with a special Lemo plug. The plug is disconnected by  
unscrewing the threaded collar.  
The voltage necessary to operate these microphones is available at the  
microphone input of the transmitter. Dynamic microphones and other  
low-impedance sources can be connected through an external coupling  
condenser of approx. 10 µF (+pole on contact 2).  
4. USING FOR THE FIRST TIME  
4.1. B 50 / B 250 QUICK-CHANGE ENERGY PACK  
Insert the batteries as described on page 22, Fig. 2 and Fig. 3.  
After insertion of the batteries, the cover of the quick-change energy pack  
is to be snapped into place. The LED display on the front side of the  
energy pack (Fig. 1) serves as a battery control display.

In addition to the visual display on the quick-change energy pack, the  
transmitter communicates the status of the batteries or the rechargeable  
batteries to the EM 1046 for presentation on the receiver display.  
FIG. 5  
RELEASING THE QUICK-CHANGE  
ENERGIE PACK  
Squeeze the catch with the thumb  
and index finger, and separate the  
transmitter from the quick-change  
energy pack.  
To attach the quick-change energy  
pack, simply let the quick-change  
energy pack snap into the  
transmitter.

The SK 250 / B 50 and SK 250 / BA 50 combinations are not possible because  
the power of the battery / rechargeable battery pack is not adequate for this  
transmitter.  
5. CHANNEL SELECTION  
To select the appropriate channel or the appropriate frequency in  
accordance with the type plate, move the channel selection switch 2 to the  
desired position.  
6. SWITCHING ON  
After attaching the quick-change energy pack, the transmitters is switched  
on by moving the operating switch 4 into the "ON" position. The red  
operating indicator 5 lights up. Should the operating indicator not light up,  
check the quick-change energy pack.

7. SENSITIVITY SELECTOR SWITCH  
The sensitivity selector switch 6 can be used to adapt the gain of the  
microphone input in 8 steps to the level of the sound expected. This  
setting is to be made in combination with a receiver which has a peak  
indicator available, such as the EM 1046. The sensitivity is set correctly  
when the "peak" indicator 5 lights up brightly during level peaks. The  
microphone is to be held or mounted in its position for later use when  
setting. The corresponding display on the EM 1046 receiver indicates a  
maximum deviation of approx. 125 %.  
In practice, the following guide values have proven themselves for the  
adjustment of the sensitivity setting:  
Position 2,3  
=
Loud voices, songs, theatre  
Position 3,4,5 = Normal voices, talkshows, interviews  
Position 6,7  
Position 8  
=
=
Soft voices  
Use only for connection with a dynamic microphone !  
8. ATTACHMENT OF THE BODY-PACK  
TRANSMITTER  
Its small dimensions and flat form make it possible to carry the transmitter  
easily in a jacket pocket or trousers pocket. The device is to be protected  
against falling out by a tight gripping clip with which the transmitter can  
also be attached to the waistband or to a belt (Page 26, Fig. 7). To attach the  
transmitter with the connections facing downwards, simply reverse the clips.  
The nylon transmitter pouch with Velcro closure (accessory) provides  
effective protection against moisture for actors who perspire heavily.

Note:  
The transmitter can also be  
attached so that the cable  
and antenna point  
downwards.  
9. LICENSING REGULATIONS  
The type plate contains the channel data and the transmit frequency data  
as well as the BZT approval, which you require for your application for  
the licence from the Post Office. It is located on the underside of the device.
