Shure A15LA Line Adapter–Converts Balanced Line Level Signals to Microphone Level (50dB Attenuation)

The A15LA is a line adapter that reduces the level of an audio signal by 50 dB, letting a balanced line level output feed a microphone level input. Use it when a playback deck, mixer output, or similar line source has to run into a mic input on a console, recorder, or wireless transmitter, so the preamp is not overloaded.
