The IMPACT on cost saving in rack-assembly

The IMPACT CONTROLLER manages and prioritises incoming audio streams based on the signal priority table sending it over the AMP-link to the DCA-2.500 amplifier A and B channels. The remote controlled zone expander units 4E-SW6 send the audio from A and B channels to the required zone(s). Using this method ensures a dynamic assignment of the audio streams to the monitored switching lines in the 4E-SW6.

The CONTROLLER is the heart of the IMPACT system. Housed in a 1U 19-inch rack-mountable frame, it manages all VACIE operations. This involves the management and prioritising of audio streams coming from the network.


CONTROLLER deals with inputs according to their own signal priority table, distributing the audio using the digital AMP-link module, which handles two prioritised streams through a dynamic assignment technique, to a maximum of 16 DCA-2.500 amplifiers.

The 4E-SW6 remote controlled zone expander units housed remotely in the easy-wire racks, work directly to the CONTROLLER. This set-up routes audio from the A and B channels of the amplifier into the required speaker lines and zone or zones. 

The CONTROLLER manages two simultaneous audio streams over an expandable switching matrix utilising 4E-SW6 modules. This facilitates expanding from a minimum of 6 speaker lines to a maximum of over 1400 speaker lines, which can be grouped into a system total of 254 virtual paging zones, using a maximum of 96 virtual paging zones per CONTROLLER.

The CONTROLLER provides all mandatory indicators according to the EN54-16 standard and provides GPI and GPO interfacing, global and local network ports, TCP-IP ports and an AMP-link that interfaces with the DCA-2.500 amplifiers over a dedicated RS485 bus for audio and data control. 


The CONTROLLER uses the same 4EVAC-manager as the COMPACT, which makes the interaction between the two systems straightforward and easily combined into one system.

Offering ‘dynamic-load-distribution’ over the speaker lines from 1 Watt to 200 W, one CONTROLLER can manage up to 16 x DCA-2.500 amplifiers with a combined output power of up to 16,000 W. 

4evac-IMPACT-Controller combined with compact 500

The CONTROLLER integrates seamlessly with the topology of the COMPACT box-on-the-wall VACIE system, which offers maximum versatility and meets today’s challenging market demands.
