The rear panel connector (labeled
MIC
) is normally provided to support the Model XDM003A External
Desktop Microphone. For higher level microphones requiring an operating bias such as an Electret
condenser microphone, install jumper JU6 to provide the operating bias and jumper JU5 to reduce the
gain of the microphone pre-amp.
Refer to Figure 8 below for the board position of JU5 and JU6. The default for these jumpers is OUT.
NOTE
The following sections discuss the connections for accessories that may or may not be available for your
set up. Please contact GAI-Tronics Customer Service for additional information.
