LT-800 Setup Instructions
5
Set the RF POWER switch on the back of the unit to Full, ½ or ¼ (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 environ-
ment, it is best to set the transmitter’s output power to its lowest level to reduce the possibility of
interference.

Connect Audio Inputs
6A
Connect the audio source(s) to one or both audio input connections. Input 1 offers a choice of balanced
XLR or ¼” phono connector. Plug your microphone into Input 1 and move the input select switch to Mic (for
dynamic microphones) or Mic + PH Power (for condenser microphones). Plug your balanced or unbalanced
audio source into Input 1. Use the following diagram:

Plug your unbalanced audio source into Input 2 and select the audio level switch for -10 dBu or +10
dBu, to match the audio level coming from your equipment.
Input 2
The LT-800 has two audio input options: Input 1 and Input 2. Input 1 is a balanced connection using
either an XLR or ¼” 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.
