Description
The PDA5/DD Hearing Loop Amplifier is a free standing constant current amplifier featuring 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.
Covering an area up to 200m2 the PDA5/DD Hearing Loop Amplifier is an ideal solution for smaller areas such as meeting rooms, offices or classrooms. For larger area coverage please see the PDA7/DD (500m2) or the PDA11/DD (1000m2).
Key Features
