The D10-2 networkable DSP hearing loop driver is part of the D Series representing the global benchmark for digital audio hearing loop systems. 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 D10-2 digital amplifier is a 10 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, and with Loopworks Measure LoopLink for easy test and commissioning.
The D10-2 features 10 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 D10-2 networkable DSP hearing loop driver 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 D10-2 also boasts Dual slope Metal Loss Control that caters for a wide range of metal loss frequency characteristics.

Indicative metal loss scenarios are based on: 0db = a building with no structural metal, -5dB = a building with reinforced concrete (re-bar) construction, and -10dB = a room with steel raised access floor tiles, -15dB = a room with steel decking or reinforced concrete and raised access floor tiles.
Multiloop area coverage calculations are based on the following assumptions: 1:1 room aspect ratio, 3mm2 copper tape laid at floor level, base current varies depending on solution employed.
