It is not practical to spund the AVC2 in a mobile situation or where visiting artistes, bands, DJs, etc. An external remote warning indicator may be connected to warn the operator that the operating level is 3dB away from the threshold at which the AVC2 will start to control level. If the average operating level is kept below the internally set threshold, the AVC2 has no effect. Products you may also be interested in The limiting threshold and peak threshold each have a preset control under the front panel.

That is to say when the control signal is removed the unit will not reset until the reset button is depressed. Reducing souund input level will gently release the attenuation provided by the AVC2. The reasons are many, such as the problems of interfacing this equipment to visiting sound systems in the time available before a performance; where to connect it; having the correct connectors available; having the time to calibrate the equipment in the venue; having technical staff available to do the work.

An anti-tamper relay is fitted avc can be connected to an external switch to improve system security. Power, limit warning, skund warning, priority override.

The priority input e. Eound 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.

Basket Your Basket fogmula empty. The AVC2 is an Automatic Volume Control unit and as the name suggests behaves just like someone leaning over the operator”s shoulder and turning the volume down each time he tries to turn it up above what is allowed.

Output impedance ohms, max. Parallel remote output will drive solid state relays for external sign switching. Audio inputs and outputs 3-pin XLR.


Formula Sound AVC2 Intelligent Stereo Automatic Volume Limiter Control Unit

This fomrula because it is fairly slow in its action and therefore has a response time of a few seconds depending aound musical content. An anti-tamper relay is fitted for added security and the unit has provision to connect an external time switch not supplied to switch between two output levels, e. The more one tries to increase the volume, the more the AVC2 will decrease it so that the system will barely change in perceived level.

Level sense taken from channels 1 and 2. It will interface with any existing or new sound installations, and is a four channel device, with a variety of application possibilities. A clip indicator is provided to show when the input stage of the AVC2 is being over driven.

As this signal level is directly proportional to the noise the loudspeakers produce we do not need a measuring microphone for the system to work. Return to Page View Basket. A bar graph meter informs he operator how much level the unit is holding. If formulq to maximum attenuation, the output level will be reduced by more than the increase in input level. Two modes of reset, auto and manual are determined by the reset button.

If the button is left in the depressed position the unit will automatically reset when the control signal is removed. The unit will keep returning to the attenuated level until the operating level is reduced to below the threshold.

The AVC2 performs as an intelligent volume control and in operation is very simple. We have supplied units to several radio stations for this application.

If the AVC2 is driven to maximum the output level will be reduced by more than the increase in input level. These are only accessible by removing the security front panel. If the level is reduced no action is vac2. If the average level is exceeded the unit will reduce the output level by fading in discrete soune steps, indicated on a LED bar graph indicator on the front panel. If the average programme level exceeds the threshold the unit will reduce its output level. There are no user controls on the AVC2 to be tampered with, only a bar graph meter showing how much control the AVC2 is exercising.


We are your one true, trade only distributor and our all-round service means that we deliver for you every time. This turns the programme level down to the attenuated level as set by the attenuation controls for avcc2 10 seconds, and has a 10 second fadeback time.

The unit contains no compressor or limiter, so the dynamic range of the dound signal will be maintained.


Product Specifications Max input level: Not in stock, please liaise with the sales team for manufacturer lead times. The action of the AVC2 is to fade between these steps and is almost undetectable in use. There is a character limit. The unit monitors the level in channels 1 and 2 and if this combined level exceeds an internally set threshold a limit warning lamp illuminates. Priority control input and remote indicators output 6 way screw-terminal connector.

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 to worry about which also means xound tampering fogmula minimised. 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.
