For example, Cobra 4 Pin radios are wired 1) Shield 2) Audio 3) Transmit 4) Receive while Midland 4 Pin radios are wired 1) Audio 2) Shield 3) Receive 4) Transmit. There are some radio brands that have the same general wiring (such as Cobra and Uniden) but that is not always the case. The list below offers some microphone wiring information.One great thing with the MH-31 is that there is an unused 5v supply connection. This allows an electret condenser microphone element to be used in place of the standard dynamic element. I decided to experiment with this, and after some testing I came up with the circuit below. Condenser microphone schematic for the Yaesu MH-31.Circuit Description and Working of the Dual Microphone Preamplifier circuit. The circuit diagram of the dual microphone amplifier is built around a low-power quad op-amp MP604. Op-Amp MP604 contains four individual op-amp. Two op-amps are used to amplify the output of MIC1 whereas the other two op-amps are used to amplify the output of MIC2.Nov 08, 2010 · Sound sensor circuit diagrams. This is an extension of the CMOS toggle flip flop circuit with the addition of two bandpass filters and condenser microphone so the relay can be toggled by whistling at it. The schematic for simple Microphone to Speaker circuit is given below - The circuit is exactly same as shown in the LM386 datasheet from Texas Instruments. We removed the 10k pot section and added additional bias circuitry of the microphone amplifier. In the circuit diagram, the Amplifier is shown with the respective pin diagrams.Between Pins 2 and 3 of the input jack and ground, ceramic capacitors C1 and C2 shunt any RF noise that might hitch a ride on the mic cable. Bad mic cables make good radio antennas! Keeping stray static at bay is the job of the diodes. Obviously, we need to keep 48 VDC out of our audio circuit.What is Microphone Schematic. Likes: 599.
