LT-803-072 Setup Instructions

5Set RF power

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.

Low, Med or High RF power

6Connect Audio Inputs

The LT-803-072 has two (2) audio input options: Input 1 and Input 2. Input 1 is a balanced connection 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 connect to an unbalanced audio source.

6A Input 1

Input 1 offers a choice of balanced XLR or ¼ in. phono connector. Plug an audio source into Input 1: move the input select switch to the type of input source being used. Select “Line” for Line Inputs, “Mic” for dynamic microphones or “Mic + PH Power” for condenser microphones. A balanced feed from a soundboard can also be used with Input 1.
