Sony MAS-A100 Manual page 39

Design the audio system so that manual volume adjustment by the mixer and volume
adjustment of the audio system for speech reinforcement (channel volume, master
volume) for the Main output from the MAS-A100 is not possible during normal
operation. To make volume adjustments during normal operation, use the MASM-1,
the web interface of each MAS-A100 unit, or the external control API.
For a sample program for control using the external API, see "B.6 Sample program"
(page 116).
