Design Guide
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). A feed from a soundboard can also
used with Input 1. Be sure the input type selected (line, mic or mic-PH PWR) matches with the output type. The
following is a wire diagram for Input 1 balanced and unbalanced connections:

Input 1: Connect the audio source(s)
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, and input 2 is two unbalaned 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 con-
nections). Use Input 2 to connect to an unbalanced audio source.
