Hello
Looks like a device to listen (or get an audio signal) from 4 channels simulaneously. Why is there a microphone in the schematic? Are those signals carried by ultrasonic sound? Never 'heard'(about) that before. A wired system that carries those four audio bands would make more sense. Juergen |
