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.

| AUDIO SYSTEM | |
|---|---|
| Frequency Response | 80Hz to 6.5kHz |
| Distortion | THD+N <0.3% 1kHz sine at full current |
| Automatic Gain Control | The AGC is optimised for speech. Dynamic range >36dB |
| Metal Loss Correction | Corrects system frequency response issues due to metal structures in a building. Gain constant at 1kHz, adjustable gain slope from 0 to 4dB per octave in 0.25dB increments. Custom dual slope MLC allows different slopes and knee frequency to be set via the menu (network models only). This does not compensate for signal loss from metal structures which can be significant. |
| Phase Shift | User selectable (network models only) at 0° or 90° between outputs |
