System Overview
There are three main parts to a Portable FM System – Input source, transmitter, and receiver.
A microphone is the most common input source for the LT-700 transmitter, although, the LT-700 can transmit two
audio inputs at once on one transmission channel. With the use of the LA-263 line cable both the inputs will be
mixed. Thus, a person can use a line input source and mic source.
