The LA-272 has a uni-directional pickup pattern. This means that the microphone’s element must be
oriented towards your mouth. It will not pick up audio very well from the side of the microphone.
The main advantage of this type of microphone is that it helps minimize feedback and picks up less
environmental noise.
•Set the microphone sensitivity switch (located inside front cover of the LT-700 Portable FM Display
Transmitter) to the MED position.
•Place the unit over your head and position the microphone as close as possible to your mouth.
For best results the mic element should be 1 to 2 inches from your mouth. This will help to ensure
that the microphone picks up your voice rather than room noise.
•Connect the earphone plug firmly to the earphone jack on the Listen receiver.
•Connect the microphone plug firmly to the microphone jack on the LT-700.
