Product Description
Williams Sound C5-2 US C-Series DSP Multiloop Driver
The C Series hearing loop drivers from Ampetronic mark a substantial development in hearing loop technology for assistive listening. Compact, elegant, and sturdy, C Series units, the most versatile and powerful solutions available in their class, feature digital signal processing and networking functionality.
Four class ‘D’ drivers (two dual output and two single output models) make up the C Series; offering a significant increase in energy efficiency over existing solutions in a similar price range.
The drivers feature a simple digital user interface, enabling accurate adjustment and providing clear indicators, system diagnostics and built-in test tones. C Series drivers are fully networkable with a Wi-Fi accessible standard browser based control panel, for remote set-up, monitoring and email alerts, and with Loopworks Measure LoopLink for easy test and commissioning.
The C5 features 5 Amps RMS current per loop output, respectively, plus ample voltage headroom, making them suitable for a wide range of applications. Installation can be performed with total confidence; unique, multi-stage filtering ensures compatibility with other systems and global EMC regulations.
This driver is available in both networked and non-networked versions.
