SW6MA-S2100Wireless Microphone

Taixing microphone using instruction .Operation of handhold microphone 1. Turn the microphone to “OFF” position, screw handhold microphone battery cover in counter-o’clock direction. Insert 9V battery, screw back the cover. 2. Turning the microphone to “ON” position, now the receiver “RF LED” indicating light on means the wireless microphone starting to work.. Turn the microphone to “OFF” position if don’t use. 3. If the indicating light of microphone darken evidently, that means the battery is less power, please change the new battery. .Remark: 1. Please avoid to place the receiver board under sunshine directly ,dusty place or moisture place and try to keep far away from the magnetic field. 2. Please avoid to place the receiver to dead corner in order to keep the good single. 3. Please take out the battery when the microphone not use for a long time so that it won’t worsen the microphone by the poor battery. 4. Please don’t throw the microphone so as to avoid the serious damage.

Transmitter working theory The MIC transform the sound into electronic signal, the signal then through C 2 coupling to network that consist C 3 and R 1 , and then through the two amplifer stages. The two amplifer stages consist of Q1,Q2 and so on. Enlarged audio signal then to the two pins of D1 through R9, the oscillating circuit consisting of transistor Q3, quartz crystal JT and other components. When the audio voltage changed then the voltage between two pins of D1 changed, and because the capacitance value of D1 is decided by its voltage so the capacitance of D1 will changed by the change of audio signal’s amplitude, the final result is the oscillating frequency will be modulated by the amplitude of audio signal. The circuit of selection frequency consist of C10 and T2 and produce 3 times’ frequency. Enlarged by amplifer stage that consist C12,Q4 and produce 2 times’ frequency by T3,C13, then the output of C15 through choosing network that consist L3,C16 and C17, then enlarged by amplifer stage that consist C18,Q5,C20,L4 and produce 2 times’ frequency, the frequency of signal change to 12 times’ original frequency totally through above processes. Then the high-frequency signal through C21, choosing frequency and transmitted out by antenna matching network C23 an L6.

ADJUSTMENT PROCEDURES 1. Transmitter Power Adjustment a). Adjust the DC power supply so that 9.0V is obtained at the battery terminals. Confirm that the power meter, dummy load and output tester are prepared. b). Turn the power on and mount a JT element (16.6416MHz) into the crystal on the PCB board. c). Adjust T2, T3, L3, L4, L5 in this order so that the power meter reading become maximum. d). Repeat procedure c several times. The RF power meter reading should be more than 0.001W when the power is on and at a normal temperature. Then check the current meter reading should be less than 35mA. 2. Transmission Deviation Adjustment a). Set up the unit for the transmission mode. b). Adjust T1 so that the frequency counter reading is 199.5 MHz c). So that the maximum deviation is 5 KHz Adjustment setup block diagram
