Signet AKM3 Lecture Room Hearing Loop Kit (PDA200E, PRO45 Mic)

Description:

The PDA200E induction loop amplifier kit (AKM3) is a cost-effective and professional assistive listening solution, designed to provide clear audio coverage for spaces up to 200m². Ideal for meeting rooms, conference spaces, places of worship, and public environments, it ensures reliable signal transmission for hearing aid users via a perimeter loop system compliant with relevant accessibility standards.

This complete kit includes the PDA200E amplifier and the Audio-Technica PRO45 hanging microphone, delivering high-quality audio input straight out of the box. The system features multiple input options, including line-level and microphone inputs with phantom power, allowing flexible integration with various audio sources. Advanced features such as metal compensation and automatic compressor-limiter technology ensure consistent intelligibility, even in challenging acoustic environments.

Housed in a durable wall-mountable metal enclosure, the amplifier is designed for permanent installations. Built-in protection systems, including short circuit protection and thermal cut-out, ensure long-term reliability, while front panel indicators provide clear system status monitoring.
