DSP Multiloop Driver System with Dante

D14-2D SYS

The D Series 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 added power of the D14 provides a solution for installations in environments containing very high levels of metal, previously not possible without the use of combiners.

This device includes Dante features.
