Dual OPA "Alice" Microphone Circuit
This is the PCB for a dual operational amplifier circuit that will mount in a BM-800 body and interface with a condenser microphone capsule such as the TSB2555B and TSB165. These are Electret with no internal FET. Also it will work with true condenser capsules that require bias voltage. This has a 12 volt output that can be used to supply the bias circuitry. The build instructable is here And a video of it in action on four microphones is here https://youtu.be/7JmeEmgNlPw
