Listen Technologies D10-2 D Series Single Loop Driver, 2x 10 Amps

The D10-2 (D Series) represents 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.

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 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 to a wide range of metal loss frequency characteristics.

Architectural Specs
The D Series MultiLoop Driver shall continuously deliver two (2) x 10 A(RMS) per channel when excited with a 1 kHz sine wave as measured with the IEC 62489-1 induction loop amplifier performance standard. Only drivers that have been tested and compliant to this IEC 62489-1 specification shall be accepted, no other substitutions will be allowed.

In a Perimeter Loop application it shall cover up to two (2) x 1,450 sq. m (15,607 sq. ft.) each. In a MultiLoop Low Loss application it shall cover up to 3,300 sq. m (35,520 sq. ft.). The MultiLoop driver shall internally incorporate two (2) loop drivers and one (1) accurate and stable 90 Degree audio phase shifter. The MultiLoop driver with the proper design shall have reduced spill to no more than 1.5 m (4.9 ft.).

The MultiLoop driver shall have a frequency response of at least 80Hz to 6.5kHz +/- 3 dB with THD+N less than 0.2%.The unit shall incorporate (AGC) Audio Gain Control optimized for speech with a compression dynamic range of >36 dB audio processing. The unit shall incorporate Dual Slope Metal Loss Correction to rectify frequency loss caused by adjacent metal structures.
