The LA-270 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
micrphone. 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 ears, wrapping it behind your head. 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 plug firmly to the microphone jack on the LT-700.
