That is to say when the control signal is removed the unit will not reset until the reset button is depressed. If the lamp is illuminated continuously for 6 seconds the limit will be activated.

The system will probably now sound distorted and generally not very nice but the volume will be at a lower than normal level.

The more the operator tries to increase the volume the more the AVC2 will decrease it, so the system will barely change avx2 perceived volume level. Balanced inputs and output are provided which may formhla strapped unbalanced with no signal loss and optional output transformers may be fitted. When the unit is reset the programme will fade slowly back to the original volume.

If the average operating level of the incoming signal is below the internally set threshold, the AVC2 has no effect. This is because it is fairly slow in its action and therefore has a response time of a few seconds depending on musical content.

Currently there are 0 item s in the Basket. Test and reset buttons, operational through the small holes in the front panel, are provided for initial setting up and testing. Additional measuring equipment may be needed during setup. Note that this unit does not measure the sound field.

The attenuation is gently reduced as the input signal is reduced. If the average programme suond exceeds the threshold the unit will reduce its output level.

The problem with sound systems is not the equipment, but the operators. The Guardian has been designed to be connected between the mixer or pre-amp of an audio system and the power amplifiers.

We cannot take away the knobs and controls which they need to do their job. Two modes of reset, auto and manual are determined by the reset button.

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.

The AVC2 fulfills the need to control fixed or installed sound systems as opposed to temporary or mobile systems. 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. 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.

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.

The control circuit can be switched between linear and A-weighting. Priority input socket is connected directly to priority output socket until the unit is triggered by the control input, then it is connected to all channels as set by the level control presets, and disconnected from the priority output socket.

The AVC2 works by controlling the signal level before it gets to fofmula loudspeakers.
