D7-2 Dante – networkable hearing loop driver

The D7-2 Dante – networkable hearing loop driver represents the global benchmark for digital audio induction loop systems. Featuring all the benefits of the Standard D7-2 driver with added Dante Input for additional Network Audio.

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 Dante 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.

AUDIO SYSTEM

Frequency Response 80Hz to 6.5kHz
Distortion THD+N <0.2% 1kHz sine at full current
Automatic Gain Control The AGC is optimised for speech. Dynamic range >36dB
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.
Phase Shift User selectable at 0° or 90° between outputs

ADDITIONAL FUNCTIONS

Fault Monitoring Indicators on the front panel;
• Clipping – delivering over the rated voltage (per channel)
• Error – Check status in menu
Temperature and loop errors reported via the status menu
Cooling Variable speed fan cooled. Front inlet, rear exhaust.
