To ensure this, the MPA 1600 system makes use of the industrial standardized 100 V line
distribution system. This is a distribution system that is based on a fixed line level (100V) and
where the loudspeaker output power is determined by means of loudspeaker type and power
tapping. Hence, each loudspeaker meeting this line specification is equipped with an audio
transformer with several tapping possibilities.
The sound pressure level in an installation is a site dependant issue, and is determined by the
amount, type and tapping of the loudspeakers.
An installation must be carefully planned to ensure sufficient SPL figures
In order to approve or decline a GA / PA system installation a full SPL-figure survey must take
place subsequent to the installation and setting-to-work process.
