This was so as to avoid panic when a fire alarm activates, the programme level in the soind should be reduced and not cut altogether, and that a mic override should provide one guaranteed microphone input to the system.
The Guardian also has the provision for controlling the maximum permitted volume level, often necessary when having to conform to noise pollution requirements.
If the level is reduced no action is taken. Test and reset buttons, operational through the small holes in the front panel, are provided for initial setting up and testing. What we can do is control the maximum level at which the system will play irrespective of what they do.

Eight controls are provided – 2 controls to set the initial sound level formila channels and ; 2 controls to set the priority attenuation level of channels and ; 2 controls formulaa adjust the priority input level into channels and ; 2 controls to set a seperate dim level for channels andindependently for each stereo channel useful for use with window and door sensors to temporarily dim the output level when open windows or doors could pollute the outdoors.
When the unit is triggered, the programme level in all four channels will be attenuated and the priority input automatically mixed into all four outputs. Priority control input and remote indicators output 6 way screw-terminal connector. Power, limit warning, peak warning, priority override. An anti-tamper relay is fitted which can be connected to an external switch to improve system security.
Turning down the volume will allow the system foormula return back to normal operating level. The operating levels are adjustable via holes fotmula the front panel. Two modes of reset, auto and manual are determined by the reset button.
If the average operating level of the incoming signal is below the internally set threshold, the AVC2 has no effect. Jumper allows faster action if required. The AVC2 works by controlling the signal level before it gets to the loudspeakers. If left in the out position reset will be manual. The more the operator tries to increase the volume the more the AVC2 will decrease it, so the system will barely change in perceived volume level.
Eventually the operator will run out of controls to turn up. It is not practical to use the AVC2 in a mobile situation or where visiting artistes, bands, DJs, etc.
The attenuation is gently reduced as the input signal is reduced. Reducing the input level will gently release the attenuation provided by the AVC2. Phantom power internally selectable.

This osund a latching push-button, the position of which sets the reset mode.
A bar souns meter informs he operator how much level the unit is holding. Sojnd should be noted that this unit is not a compressor and will not significantly change the dynamic range of the music. Product Features There is no reduction in the dynamic range of the system under normal operating conditions The AVC2 has no external controls for the operator foemula worry about which also means that tampering is minimised.
There is a character limit. The action of the AVC2 is to fade between these steps and is almost undetectable in use. More detailed technical information is available in the brochure. Print Print with pricing Print unpriced. Additional measuring equipment may be needed during setup. The unit contains no compressor or limiter, so the dynamic range of the incoming signal will be maintained.
