Setting Microphone Gain
The QM-FTDC provides variable gain for the microphone inputs. The following
procedure is used to set the optimal gain for a microphone input.
Use the Realtime Mode in SystemBuilder to control phantom power, gain and gate
settings and to monitor the gate, normal and clip level indicators. For information on
using SystemBuilder software, refer to the extensive help information provided with
the software.
NOTE:
The input gain is independent of the system’s output volume level.
