Shure A15LA

The A15LA has a balanced bridging input with 50 dB attenuation. Use it to connect high-level line or Aux Outputs to low-impedance microphone inputs. It will attenuate the output from such devices as mixers, tape recorders, tuners, or phono preamps to make them compatible with balanced low-impedance units. The A15LA can be directly connected to either balanced or unbalanced sources. If the source is unbalanced, connect it to pin 2 ("hot") and pin 1 on the A15LA input; no connection is required to pin 3.
