User manual SENNHEISER SER 10

[. . . ] The signal source can be adynamie iTiicrophone, a condenser microphone with 12 V AB-powering or an AF-line (+ 6 dB). To avoid irradiations lrom the nearby antenna, microphones with metal housings should be used (e. Both, transmitter and receiver can be operated seperately or simultaneously without any drawbacks. [. . . ] With several SER 10 relay-stations can be built up at which directional antennas should be used, since relay stations are stationary. Additionally it is possible to leed the line input with a [Tlodulated signal lor remote control purposes. The same input can be used lor wireless digital data transmission, il the data are prepared to lit the AF-Irequency range 01the transmitter. Another possible application could be the use 01the SER 10 in a car or stationary to address a large number 01receivers, as it is necessary lor police actions, constructions teams, guide systems etc. the transmitter is powered Irom the accu GZB 4-2. This accu can be recharged within one hour with the charging unit SZL 25. a protective circuit prevents the overloading 01the accumulator. For stationary operation the power supply GZN 10 may be used. The SER 10 comes with a broad shoulder strap to easier the transportation during outdoor reportings. For this purpose selector switch 2 has to be set to position "TX in" and the deviation control must be turned cw (starting from the lully ccw position) until the sound peaks cause apointer dellection of 50 scale divisions. An increase of the input level above nominal deviation wouldn't result in an increasement 01the AF-deviation, because 01an control amplilier which becomes effective in that case. Two channels with an output power 011 W resp. The output power can be monitored with the indicating instrument 1 il the indication selector switch is set to position "TX out". At 10 W output power and a correct termination 0150 Q the pointer 01the indicating instrument must be within the red lield and at 1 W output power the reading should be about 30 scale divisions. [. . . ] A lully charged accu (15 V) will give a reading within the red field of the instrument.
