The SM 1008 wireless microphone system consists of a
0 EM 1008, which can be operated with a variety of special antennae.

The Mikroport transmitter is operated trom an ordinary 9 V battery, Standard units are designed for two trequencies:

where there is a high ambient noise level, reverberation, or the possibility of acoustic feedback, it is recommended that the Model MD 4008
is desired, special microphones may still be used, connected to the micro-
phone socket of the SK 1008 transmitter via a short cable. The most frequently used unit, for this application, is the Model MD 214/1 Lavalier suspension microphone. Besides double internal suspension, which renders this microphone strongly resistant to noises produced by friction, the Model MD 214/1 dynamic lavalier microphone has a shaped frequency response that compensates for attenuation of high frequencies caused by the chin of the speaker.

Power for these microphones is obtained from the Mikroport transmitter battery.

1.4Antennae
The wire antenna supplied with the Mikroport receiver does not have the same reception performance as the Model TA 203 telescopic accessory antenna. If a Ionger antenna cable is required, e. g., for diversity reception, (See Section 4.1), it is recommended that a tuned
