hi,Then if the LDR is ok. What will be again the cause of the problem?
Please make your own thread and not hyjack this completely different thread.I have designed and constructed a microphone amplifier circuit using LM301 with a line driver SSM2142 and a line receiver SSM2141.The circuit is supposed to pick up any voice/audio by the mic and send it via 100m Twisted Pair Cable to a PC for recording and analysis.I am using an omnidirectional Yodata Laptop Microphone,but i get nothing on the output.The circuit(amplification etc.) on its own is perfectly working but the audio/voice part is not,cracking my head.I have tried a ready-made Phillips microphone on my circuit and i works perfectly but the mic described for the job turns me down..Please help
