INSTRUCTIONS FOR USE
MIKROPORT BODY-PACK TRANSMITTER

Brief description SK 3063-U
In combination with a connected microphone, the transmitter can be used
as a wireless 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-to-noise ratio, SK 3063-U 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 3031/32-U /
EM 3532-U), 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 channels
•Sennheiser "HiDyn plus" noise reduction system
•Signal-to-noise ratio > 112 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 transmitted to the receiver
•Operation and peak deviation indicator

Microphone selection
The MKE 2-4, MKE 102-4 (omnidirectional pick-up pattern) and
MKE 40-4, MKE 104-4 (cardioid pick-up pattern) clip-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).
Using for the first time
B 50 / B 250 quick-change energy pack
Insert the batteries as described on page 15, Fig. 2 and Fig. 3 (delivery
includes power pack B 50).
After inserting 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.

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 trans-
mitter communicates the status of the batteries or rechargeable batteries to the
EM 3031/32-U / EM 3532-U for presentation on the receiver display.

Channel selection
To select the appropriate channel or the appropriate frequency in
accordance with the type plate, move the channel selector switch 2 to the
desired position.
Switching the transmitter on
After attaching the quick-change energy pack, the transmitter is switched
on by moving the operating switch 4 into the "ON" position. The red
operation indicator 5 lights up. Should the operation indicator not light up,
check the quick-change energy pack.
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. The sensitivity is set correctly when the "peak"
indicator 5 lights up during level peaks. The microphone is to be held or
mounted in its position for later use when setting.
In practice, the following guide values have proven themselves for the
adjustment of the sensitivity setting:
Position 1,2 = Loud voices, songs, theatre
Position 3,4,5 = Normal voices, talkshows, interviews
Position 6,7 = Soft voices
Position 8 = Use only for connection with a dynamic microphone !

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. To attach the transmitter with
the connections facing downwards, simply reverse the clips.
The transmitter pouch SK 50-T with Velcro closure (accessory) provides
effective protection against moisture.
Note:
The transmitter can also be
attached so that the cable and
antenna point downwards.
