Product Description
Williams Sound C7-2 US C-Series 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.
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 C7 features 7 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.
