The PDA103 is a true current mode, hearing loop amplifier. It may be surface-mounted and is designed to cover ticket counters up to 1.2m2 (PDA103C kit version), or rooms up to 50m2 (PDA103R/L/S kit versions). See installation manual and specifications for more information.

Product Features

• Each kit contains everything you need to create a high quality hearing loop system for a room up to 50m2 (7m x 7m)
• PDA103R kit is ideal for small room applications where equipment needs be mounted above suspended ceilings, etc.
• PDA103 amplifier includes a 3.5mm microphone input, a line level input and an \'outreach\' socket
• Metal compensation control helps improve intelligibility in rooms with high metal content
• Adjustable mic, line level and \'outreach\' controls.
• Drive (level) control allows the amplifier output stage to be set-up to suit the exact characteristics of the application.
• State-of-the-art audio processor features an automatic gain control which compensates for poor microphone techniques and helps suppress loud noises, hisses and clicks
• Limit, Peak, Loop Fault and Power On indicators
• Designed to be wall-mounted using the keyholes provided
• Meets and exceeds the requirements of BS7594 and EN60118-4 when correctly installed
