Wall Mounted Induction Loop System for the Hearing Impaired
Wall Mounted Induction Loop Kit |
---|
The PDA200Ehas revolutionised the induction loop marketplace by bringing the ability to understand, install and appreciate the technology involved to a whole new client base.
Straightforward internal screw connectors are required. By following the simple set-up procedure, no further adjustments are necessary, allowing a top quality assistive listening system for the hard of hearing to be set-up in its entirety by new and experienced installers alike.
No less than four easy-to-access inputs are provided:
The amplifier’s state-of-the-art current drive audio processing circuitry includes an automatic compressor/ limiter, which maintains the loop signal within a small dynamic range to improve intelligibility. Manual adjustments can also be made using the amplifier’s internal tamper resistant drive, level and tone controls, allowing the system to be tailored to suit the exact requirements of any room.
For ease of specification and installation the PDA200E is available on its own or in the following kit formats:
• AKM1 Meeting/seminar room kit
• AKR1 Waiting room kit
• AKT1 TV/music lounge kit
• AKW1 Place of worship kit 1
• AKW2 Place of worship kit 2
• AKH1 Health and fitness club kit
• AKL1 Lecture room kit
• AKU1 Retail unit kit
