The two microphones are easily mterchangeable. They are simply plugged into the socket on the transmitter and screwed in. The microphones are powered lrom the transmitter battery. Together with the SK 1010 they lorm one unit wh ich can be used as a hand- held microphone or may be worn around the neck as a Lavalier microphone. To avoid possible breath and wind noises it is advisable to use the included windshield MZW 4012 A when using the transmitter as a hand held microphone.

The especially Ilat constructlon 01the transmitter allows it to be used as a pocket transmitter. For this application the Lavalier clip-on mlcrophone MKE 10, MKE 40 Rand MKE 2 R have been devel- oped. The MKE 10 and MKE 2 R have an omnldirectional characteristic and the MKE 40 R cardioid characterislic. Both microphones are powered by the transmitter.

Dynamic microphones may be connected via the connecting cable DA 1012 N or DA 1012 U to the SK 1010.

Wearing the transmitter

When being worn as a Lavalier-microphone the transmitter is kept away Irom the clothes by a small carrying device, in order to avoid picking up Iriction noises. To lasten around the neck, the carrying device CD(Iig. 2) is lixed to the transmitter by inserting the locking inserts @ 01the carrying device mto the side opening @ 01 the transmitter housing and the device turned upwards. The cord 01 the carrYlng devlce is hooked into opening @ on the holder.

For operation wlth clip-on microphones the transmitter is to be worn

as shown in lig. 7 - 9. Another way 01wearing the SK 1010 is the use

01the holder SZK 1012 (Iig. 10).

Operation

Important information:

The wiring arrangement of the input socket was chosen in such a way that the transmitter may be remote-controlled from an external switch. Therefore, the operating voltage lead was interrupted and led across socket contacts 6 and 7. The transmitter may be accordingly only opera ted when this interruption is rejoined via a wire bridge in the microphones. MKE 2010 and 4010, as weil as clip-on microphones MKE 10, MKE 40 Rand MKE 2 R contain this bridge. The connecting cables DA 1012 N and DA 1012 U, suitable for connecting dynamic microphones, also contain this bridge.

Belore operating the transmitter one should check to ensure that transmitter and receiver Irequencles coincide. The Identilication sticker CDIn the battery compartment contains the transmission Irequency designation and the licence number, which are required when applying lor a Ilcence to operate your transmitter.

For the lollowing please observe lig. 4: beside the microphone and microphone socket respectively you will lind a small operatmg

panel wlth the sWltch CD,two LEDs @ and @ and the sensitivity control 0.

In the position "Off" the unit is completely inoperative. II the operation switch IS put into position "Test", Ilrst the green LED @wililight up il the battery voltage IS more than 6 V. Proper operation can be expected il this control diode lights up brightly. II this diode glows only dimly the battery should be changed or the accumulator charged.

Control 0 enables the sensitivity 01the transmitter to be changed. Since the proper lunctionmg 01the system is extremely dependent on this control being set properly please read the lollowing section carelully.

Carry out a voice test! Position the microphone as it will be used later on. The test noise is a long-drawn-out "ueueue". Switch CD should be set to "Test" and the sensitivity control 0 should now be turned clockwise lrom position 1 - on the 1 to 7 scale - until the red LED @only Ilashes on and off at the volume peaks. In this position you still have a large modulation range, such that even sounds which are appreciably louder are transmitted without distortion.

Good results will be achieved with the sensitivity control set to the lollowing positions:

Please remember that whenever the transmitter is hand-held the windscreen MZW 4012 A included in the screw-in microphones packaging should be used.

IIovermodulation still occurs when the rated swing is reached the

controlled amplilier will switch on. This enables a distortion-Iree transmission even when the modulation range is grossly exceeded. This mode does, however, have the slight drawback that "breathing" noises (typlcal lor every controlled amplilier) must be expected.

In cases where the transmitter is being used together with a hall PA- system please ensure that the sensitivity control 0 is not used to adjust the volume. The volume adjustment should be exclusively carried out on the PA-system's amplilier and should be so adjusted

that there is an ample range available belore the leedback level is reached. II noticeable distortion occurs when the transmitter is cor-

rectly adjusted then the problem is in the overloading 01 the input stage 01 the PA-amplilier, caused by the relatively high output signal (1.5 V) 01 the receiver. II this is the case it is recommended that a suitable attenuated signal should be taken lrom the receiver output. Piease check with the operating manual 01your receiver.

Phono input

The SK 1010-6 and SK 1010-7are equipped with a 2.5 mm !/Jjack socket which enables the connection 01tape recorders etc. The input sensitivity is 120 mV at 57 kil. Higher signal levels may be applied as they are reduced bya limiter amplilier, but it should be avoided whenever possible. II the signal level is much higher than 120 mV, we recommend the insertion 01 an external potentiometer into the signalline as the sensitivity control 01the transmitter is inoperative lor this input.

Hint: The microphone module used must remain plugged in as it contains a wire bridge between pin 6 and 7. Without the wire bridge the transmitter can'tbe put into operation. II you want to do without microphone an external wire bridge has to be connected.

Battery / Accumulator operation

IIyou are using the more powerful100 mW resp. 50 mW transmitter please note that the transmitter will only operate properly with alkali- manganese batteries. This type 01 battery is slightly more expensive than the equivalent zinc-carbon battery, but they can supply power
