| What does a microphone amplifier do? Recorders almost all have a "Line Input" for accepting a signal to record. This line input needs a strong signal, a bit like the signal that comes from a headphone socket. The signal from a microphone is much smaller and if plugged into the line input will not normally produce an audible result. Some recorders have a separate microphone input; some do not and require a microphone amplifier/preamplifier to increase the signal level so it can be recorded successfully. This is what the FEL Battery Microphone Amplifier does. | |
