Product Description
Shure A15LA Line Adapter - XLRF to XLRM
Attenuator reduces the level of an audio signal by 50dB, which allows a line level output to be connected to a microphone input.
This unit has a balanced bridging input with 100 kilohm input impedance and 50 dB loss. Use the A15LA 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 3 ("hot") and pin 1 on the A15LA input; no connection is required to pin 2.
General Description
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.
