PLN-1LA10
The Plena Loop Amplifier is a cost-effective amplifier designed to drive a wire loop installed in the floor or ceiling, covering an area of up to 600 m2 per amplifier. This solution enables hearing-aid users in the area enclosed by the wire loop to hear all announcements, or music. Hearing-aid users can set their devices to the T-mode setting to receive the signal coming from the loop. They receive announcements in excellent audioquality, without the background noise or reverberations that normally impair intelligibility for people with hearing disabilities.
FEATURE
- High power, current driven amplifier
- Two microphone/line inputs, one priority input (100 V)
- Selectable frequency range and tone controls
- Limiter and automatic gain control (AGC)
- Integrates in an EN 54‑16 and EN 60849 compliant system
