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 Controls and connections ANTENNA SOCKET CHANNEL SELECTOR SWITCH OPERATING TIME DISPLAY ON / OFF SWITCH OPERATION / PEAK DEVIATION INDICATOR SENSITIVITY SELECTOR SWITCH FOR MICROPHONE INPUT MICROPHONE INPUT 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 .F (+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.

PERFECT FUNCTIONING OF THE TRANSMITTER IS GUARANTEED ONLY WITH THIS TYPE OF BATTERY. BA 50 / BA 250 quick-change energy pack The LC display on the front side of the energy pack (fig. 4) serves as a battery control display.

FIG. 4 In addition to the visual display on the quick-change energy pack, the transmitter communicates the status of the batteries or rechargeable batteries to the EM 3031/32-U / EM 3532-U 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. 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.
