The A15LA is a 50 dB attenuator. Use it to connect a line-level or aux-level output from devices such as mixers, tape recorders, and CD players to a mic-level input.
The A15LA input can be connected to either a balanced output or an unbalanced output. If the output is unbalanced, connect the audio “hot” lead to pin 2 of the A15LA and connect the audio ground lead to pin 1 of the A15LA. Make no connection to pin 3 of the A15LA. Refer to the following diagram.
