In response to noise level regulations and demands from the trade for a level control unit which will work with any audio system, Formula Sound have designed the AVC2. It is possible to dim the signal by 20db if required. The reasons for installing this equipment would be to address: This explains the AVC2 in basic simple terms.

Eight controls are provided – 2 controls to set the initial sound level of channels and ; 2 controls to set the priority attenuation level of channels and ; 2 controls to adjust the priority input level into soumd 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.

An input clip indicator is also provided.

We cannot take away the knobs and controls vac2 they need to do their job. Balanced inputs and output are provided which may be strapped unbalanced with no signal loss and optional output transformers may be fitted. If the average operating level of the incoming signal is below the internally set threshold, the AVC2 has no effect.

More firmula technical information is available in the brochure. It will interface with any existing or new sound installations, and is a four channel device, with a variety of application possibilities.

This is forjula far the largest use of this product. When the unit is reset the programme will fade slowly back to the original volume. Although the AVC2 will control any sound system and do so in a way that won”t embarrass or upset anyone it can only perform satisfactorily if it avx2 installed and calibrated correctly in the venue.

The unit may be connected to 4 channels of audio, normally 2 stereo pairs. Vormula, we are told, is knowing that you can turn a volume control down as well as up.

The unit will keep returning to the attenuated level until the operating formyla is reduced to below the threshold. The system will probably now sound distorted and generally not very nice but the volume will be at a lower than normal level. The problem with sound systems is not the equipment, but the operators. 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.

If the AVC2 is driven to maximum the output level will be reduced by more than the increase in input level. The limiting threshold and peak threshold each have a preset control under the front panel. The unit contains no compressor or limiter, so the dynamic range of the incoming signal will be maintained.


If the lamp is illuminated continuously for 6 seconds the limit will be activated. The operating levels are adjustable via holes in the front panel. Maturity, we are told, is knowing that you can turn a volume control down as well as up It should be noted that this unit is not a compressor and will not significantly change the dynamic range of the music.

The unit is not restricted to entertainment venues or fire alarm procedures however, and may be used with any sound system where a priority override is required — such as shopping centres, malls and other public areas where security announcements are required. The AVC2 formuka the need to control fixed or installed sound systems as opposed to temporary or mobile systems. At maximum input level the output will actually be lower than the normal level.

A line level automatic level control device intended for noise control applications. Two modes of reset, auto and manual sond determined by the reset button.
