SS 6900n V6 microphone wiring
The standard fist mic which comes with the Superstar 6900N, and many of the other clones, has 3 buttons in addition to the PTT switch.
If you are wiring up another microphone for use with this radio it is important to not connect any wire to pin 4 on the 4 pin mic plug. FEATURES, FUNCTIONS AND SPECIFICATIONS: 4-Pin Dynamic Microphone, 150 Ohm WIRING OF MIC CABLE: 1 Common Ground 2 Mic Audio 3 PTT (connected to Pin 1 for TX) 4 +5V Never ground Pin-4, this will damage the radio. |
