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.

D7-2 networkable DSP hearing loop driver

The D7-2 networkable DSP hearing loop driver represents the global benchmark for digital audio induction 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 D Series range consists of 4 class 'D' drivers (3 dual loop output and 1 single output models); meaning a 60%+ increase in energy efficiency over existing solutions. 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 D7-2 features 7 Amps per loop output respectively plus ample voltage headroom, making it the most flexible solution on the market, suitable for a huge range of applications.

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.
