Sound and Volumes
With intercoms operating as a loud speaker and the monitor also acting as a loud speaker, it is
important to set up the speech volumes carefully.
1. Reduce the mic and speaker volumes to minimum levels on the door station and set the indoor
monitor volume at approximately 25%.
2. Keeping the microphone volume at minimum, slowly increase the speaker volume on the door
station to a level which is acceptable. Do not increase the speaker volume more than is
necessary, otherwise feedback or clipping will occur.
3. Adjust the monitor speaker volume as necessary, again keeping it as low as possible.
TIP: Adjusting the microphone sensitivity on the door station is not recommended. For most
installs it is best to keep it at the absolute minimum level.
