The problem with sound systems is not the equipment, but the operators. Login for Trade Price.
If the level is reduced no action is taken. 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 is installed and calibrated correctly in the venue.
Web design by Realnet. It should be noted that this unit is not a compressor and will not significantly change the dynamic range of the music. A line level automatic level control device intended for noise control applications. 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 product has been added to your basket.
It is possible to dim the signal by 20db if required. The system will probably now sound distorted and generally not very nice but the volume will be at a lower than normal level.
Peak threshold limiter adjustable relative to standard limit threshold fast-acting limiter for peak protection. If the button is left in the depressed position the unit will automatically reset when the control signal is removed.
If left in the out position reset will be manual. Limit may be disabled by adjusting the internal threshold preset to a sufficiently high level. The mixer or pre amp feeding the AVC2 will probably be clipping, but the system will actually be at a lower than normal level. Print Print with pricing Print unpriced. The limiting threshold and peak threshold each have a preset control under the front panel.
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. We are your one true, trade only distributor and our all-round service means that we deliver for you every time. DJ microphone may be at mic or line level as selected by internal switchwith phantom power now available on the Mk3 version.
These are only accessible by removing the security front panel. D bar graph meter on the front panel of the unit. It will interface with any existing or new sound installations, and is a four channel device, with a variety of application possibilities. This is because it is fairly slow in its action and therefore has a response time of a few seconds depending on musical content. Priority control input and remote indicators output 6 way screw-terminal connector.
Jumper allows faster action if required. This is by far the largest use of this product. Reducing the input level will gently release the attenuation provided by the AVC2.
This explains the AVC2 in basic simple terms. 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. Parallel remote output will drive solid state relays for external sign switching. The control input is connected to the fire alarm or whatever triggering method has been decided.
Turning down the volume will allow the system to return back to normal operating level. When the unit is reset the programme will fade slowly back to the original volume. Not in stock, please liaise with the sales team for manufacturer lead times. 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. Phantom power internally selectable.
Output impedance ohms, max. Balanced inputs and output are provided which may be strapped unbalanced with no signal loss and optional output transformers may be fitted. Product Specifications Max input level: If the AVC2 is driven to maximum the output level will be reduced by more than the increase in input level.
There is a character limit. The Guardian also has the provision for controlling the maximum permitted volume level, often necessary when having to conform to noise pollution formla. The Guardian has been designed to be connected between the mixer or pre-amp of an audio system and the power amplifiers.
The control circuit can be switched between linear and A-weighting. The reasons for installing this equipment would be to address: The AVC2 performs as an intelligent volume control and in operation is very simple. Eventually the operator will run out of controls to turn up. 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 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.
If driven to maximum attenuation, the output level will be reduced by more than the increase in input level.
The Ac2 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. A clip indicator is provided to show when the input stage of the AVC2 is being over driven. If the lamp is illuminated continuously for 6 seconds the limit will be activated.
