Shahriar Posted April 8, 2010 Report Share Posted April 8, 2010 HiI am working in an hospital. there we have a room where doctors are isolated from nurses because of the X-ray.But sometimes doctors should talk to nurses. this is done by a small condenser Microphone mounted on the ceiling (On Top of the doctor head) and a pair of PC speakers in the nurses room. the distance between the Mic and Speaker is around 12 meters and I think this is why nurses can not hear what the doctor say clearly;I think If I use an amplifier completely close to the Mic and convert its output to a balance output, then send the balance output to a differential amplifier in the nurses room, then we can have a more clean sound!What do U think? Can anybody tell me how can I convert the condenser Mic output to a balance output?Here's a pic of what I plan to do.ThanXShahriar Quote Link to comment Share on other sites More sharing options...
