SIGNET AFILS LOOP AMPLIFIER SYSTEMS - Phase shifting, desktop

SIGNET PRO5/DD INDUCTION LOOP AMPLIFIER Phase-shifting, desktop, for areas up to 200m2

Signet’s PDA and PRO series of phase-shifting 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. This series of AFILS loop amplifiers are also available as wallmount amplifiers, see SIGNET AFILS LOOP AMPLIFIER SYSTEMS - Phase shifting, wallmount

PDA5/DD

PDA5/DD, PDA7/DD, PDA11/DD - LED interface

PDA5, PDA7, and PDA11 constant current amplifiers feature phase-shifting technology to give consistent coverage with low chance of dead spots, and minimal overspill. An LED interface along with four membrane control buttons aids navigation and easy setup, whilst also giving clear indication of operation and fault status.

Model coverage

PDA5/DD	2x 3.25 Amp	200m2	(approx. 14 x 14m)
PDA7/DD	2x 5 Amp	500m2	(approx. 22 x 22m)
PDA11/DD	2x 7.5 Amp	1000m2	(approx. 31 x 31m)

All models have the same front panel functionality, and rear panel connectivity including 2x selectable mic/line inputs on 3-pin XLR, 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 binding posts, and line output on 3-way Phoenix connector. There is also a 3-way Phoenix connector for fault relay, and a single mains IEC connector is also positioned on the rear panel.

PRO5/DD, PRO7/DD, PRO11/DD - OLED display

PRO5, PRO7, and PRO11 have the same functionality as the PDA5, PDA7, and PDA11 amplifiers above, however in place of the LED interface is an OLED display giving more in-depth information, ease of setup, and fault and diagnostics feedback. PRO/DD models also include a ‘Toslink’ optical input for connection to devices such as TV or sound bar.
