LT-803-072 Setup Instructions
5
Set the RF POWER switch on the back of the unit to High, Medium, or Low (Level is indicated on the
LCD display by number of dots above Listen logo). The amount of transmitted RF power that you will
need depends on your application. If you are operating multiple transmitters in the same environment,
it is best to set the transmitter’s output power to its lowest level to reduce the possibility of interference.

using either an XLR or ¼ in. phono connector. Input 2 has two unbalanced mixing phono connectors.
Use Input 1 if you are using a microphone or if you have a balanced connection such as from a
professional audio mixer (you can also use Input 1 for unbalanced connections). Use Input 2 to
