D SERIES MULTILOOP™ DRIVER (14 AMPS X 2)
The D14-2 (D Series) represents the global benchmark for digital audio induction loop systems.
Features
The compact, elegant and sturdy units not only feature digital signal processing and networking functionality, but are also the most versatile and powerful solution available.
The D14-2 hearing loop amplifier is a 14 Amp dual output class ‘D’ driver; meaning a 60%+ increase in energy efficiency over existing solutions. Both drivers feature capacitive touch front panels with intuitive menus, built in test signals, and are fully networkable with a Wi-Fi accessible standard browser based control panel for remote set-up, monitoring and email alerts.
The D14-2 features 14 Amps per loop output plus ample voltage headroom, making it the most flexible solution on the market, suitable for a huge range of applications. The added power of the D14-2 provides a solution for installations in environments containing very high levels of metal, previously not possible without the use of combiners.
In another first for high-power Class D Induction Loop drivers, installation can be performed with total confidence, as unique multi-stage filtering ensures compatibility with both other system equipment and global EMC regulations. The D Series also boasts Dual slope Metal Loss Control that caters for a wide range of metal loss frequency characteristics.

Specifications
Audio
| Frequency Response | 80 Hz to 6.3 kHz ±3 dB |
| Distortion | THD+N < 0.2 %, 1 kHz sine wave at full current |
| AGC | Optimized for Speech, Dynamic Range > 36 dB |
| Metal Loss Correction | Corrects system frequency response 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 2 slope MLC allows different slopes and transition frequency to be set via the menu.This does not compensate for signal loss from metal structures which can be significant. |
