SIGNET AFILS LOOP AMPLIFIER SYSTEMS - Phase shifting, wallmount

Signet’s PRO series of phase-shifting, Class D induction loop amplifiers have been designed and manufactured in the UK to suit areas up to 1000 square metres such as meeting rooms, offices, churches, classrooms, or theatres.

Available as wallmount or desktop amplifiers, see SIGNET AFILS LOOP AMPLIFIER SYSTEMS - Phase shifting, desktop; PRO5, PRO7, and PRO11 constant current amplifiers feature phase-shifting technology to give consistent coverage with low chance of dead spots, and minimal overspill. An OLED display along with four membrane control buttons aids navigation and easy setup, whilst also giving clear indication of operation and fault status.

Model coverage

PRO5/DW 200m2 (approx. 14 x 14m)
PRO7/DW 500m2 (approx. 22 x 22m)
PRO11/DW 1000m2 (approx. 31 x 31m)

All wall mounting models have the same front panel functionality, and rear panel connectivity including 2x selectable mic/line inputs on 3-way Phoenix connectors, 1x outreach input via 4-way Phoenix connector for connection to up to ten compatible outreach plates, see SIGNET AFILS LOOP AMPLIFIER SYSTEMS - Accessories - Outreach Plates; loop output on 4-way Phoenix connector, and line output on 3-way Phoenix connector. There is also a 3-way Phoenix connector for fault relay, and a ‘Toslink’ optical input for connection to devices such as TV or sound bar. These wallmounting amplifiers require a fixed mains electric connection. Once attached to the wall, the front panel can be removed to access I/O connectivity.
