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.

4.2. BA 50 / BA 250 QUICK-CHANGE ENERGY PACK
The LCD display on the front side of the energy pack (Fig. 4) servers as a
battery control 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.
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.

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.
