Williams Sound DL207 NET Digi-Loop DSP Dual Channel Loop Amplifier

Description

Details

Digi-Loop is definitely state-of-the-art – the first of its kind to maximize modern amplifier technology. Its network-control capability provides seamless, remote system set-up, operation and monitoring via laptop or tablet. DSP audio processing offers flexible, powerful software control of mixing, equalization, compression and more. Powerful Class D, pulse-width amplifiers maximize efficiency.

The Digi-Loop's amplifier design offers either single or dual 9.5 A rms loop outputs for perimeter loop(s), single array(s), dual loop, or phased-array configuration. A 70-100 V input provides connection to a distributed speaker/paging system, ensuring announcements are heard by loop users.
