High Impedance Microphone Wire Diagram. In case a high impedance microphone is being used the signal can be directly connected to the junction point of capacitor c7 and the collector of the transistor. Cp8201 specifications input impedance 250 ohms nominal output impedance 50000 ohms nominal frequency response 20 20000 hz connectors xlrf in 1 4 plug out.
These devices require the input of a high impedance amplifier this circuit also has a low damping value. Disconnect the two terminal impedance selection socket see figure 2 from the rear of the male insert and reconnect the socket in the reverse position so that pin 3 of the male insert is inserted in. Here is how we wire our reslo microphones and their cables at xaudia with equivalent xlr numbers.
Most vintage transmitters require these high impedance microphones to operate properly.
To use plug the xlrm type connector of the microphone cable into the xlrf type connector of the cp8201. Plug the 1 4 output connector of the cp8201 into the high impedance electronic input. This long high impedance circuit is also very sensitive to rf pickup. The diagram below shows the configuration of each of the 3 outputs.
