REDBACK Attenuator Volume Control 5 Zone Evac - 100V Line
The Redback 5 Zone Attenuator Volume Control Evac is a practical rackmount solution for managing speaker volume across multiple zones in a 100V line commercial PA system. Available from Concert AV Melbourne, this unit is designed for installed audio environments where reliable zone control and emergency override functionality are essential.
Built into a standard 2RU 19-inch rackmount panel, this controller can be configured as five single inputs to five outputs or as one input to five outputs, giving installers flexible options depending on the system design. Each zone supports a 100W load capacity, with a total panel capacity of 500W.
Flexible 5 Zone Volume Control
This unit provides five zone outputs, with each zone offering 10 volume positions plus off. That makes it a strong choice for commercial spaces where individual area control is important, including schools, offices, warehouses, hospitality venues and public buildings.
Designed for 100V Line PA Systems
The Redback attenuator is designed specifically for 100V line commercial PA systems. Rear-panel heavy duty screw terminals make installation straightforward, while the included engraving strip helps clearly label zones for easier system identification and operation.
24V DC Override for Evac Systems
A key feature of this model is the 24V DC override relay, which allows the volume controller settings to be bypassed when required. This makes it suitable for evacuation and emergency announcement systems where paging or alert signals need to take priority.
Rackmount Installation Made Easy
Housed in a 2 unit (88mm) 19-inch rack panel, this attenuator is easy to integrate into professional PA racks and control systems. It is a practical option for installers who need a neat, organised and dependable multi-zone volume control solution.
