Signet PDA5-DD Phase-shifting induction loop amplifier with LED display

General Description

The Signet PDA5-DD is a constant current, class-D, free-standing, phase-shifting induction loop amplifier that is ideal for use in small to medium size rooms up to a maximum of 200 square metres.

This entry level pro amplifier uses a simple LED user interface.

Features

Up to 200m² coverage
Dual output for two separate induction loops for one phase-shifting low-spill loop
Line level and microphone level (with selectable phantom power) XLR sockets
Outreach connector allows up to 10 utility plates to be added
Anti-tamper lock function prevents unauthorised adjustment of system settings
Class-D output stage for maximum efficiency and very high output
Short circuit protection against loop faults for increased reliability
Fault relay & graphical display provide clear indication of operation and fault status
Designed and manufactured in the UK

Delivery Includes

1 PDA5-DD Phase-shifting induction loop amplifier
