This was so as to avoid panic when a fire alarm activates, the programme level in the venue should be reduced and not cut altogether, and that a mic override should provide one guaranteed microphone input to the system.

Limit may be disabled by adjusting the internal threshold preset to a sufficiently high level. The level is reduced in discreet steps indicated by the L.

It is possible to dim the signal by 20db if required. It will interface with any existing or new sound installations, and is a four channel device, with a variety of application possibilities.

It should be noted that this unit is not a compressor and will not significantly change the dynamic range of the music. Peak limiting, relative to this, is also provided at a much faster speed, to protect from transients.
