Introduction
Introduction
Your Listen microphone is designed to provide high quality audio when used with a
Listen LT-700 Portable FM Display Transmitter. Listen microphones will work with
LT-700 units on either 72 MHz or 216 MHz. Your Listen microphone will also work with
any product that supplies 3 VDC phantom power and conforms to the diagram below.
To achieve the desired audio quality from your Listen microphone, it is important to
use it as instructed. The instructions for your microphone provide guidelines on
placement and use.
If you experience trouble with your microphone, check the troubleshooting section of
this manual first to try to resolve the problem. If you are still having difficulties, contact
Listen support (support information available on inside cover of this manual).

the microphone element. The main advantage of this type
of microphone is that it does not have to be oriented directly
towards your mouth for good audio pickup.
The LA-261 Lavalier Microphone is a high performance, non-directional
microphone that clips on your collar or lapel.
