Williams AV DL207 SYS Medium-Area DPS Induction Loop System with Network Control

Designed for venues that require reliable assistive listening and straightforward system management, the Williams AV DL207 SYS medium-area induction loop system delivers DSP-processed audio and fast, repeatable calibration so speech is clear for users with hearing aids. The DL207 SYS combines dual loop outputs (2 x 7 A) and support for phased-array or perimeter loops with a 9 kHz maximum frequency response to maintain speech clarity across seating areas. Installers benefit from on-board calibration tools, a pink-noise generator and USB/PC app configuration, while IT teams get Ethernet-based network control for remote monitoring and firmware updates. Priority input and audio override make the DL207 SYS ideal for integration with security paging, emergency notification and building monitoring systems where announcements must be heard immediately. Rack-mountable and compatible with 120/230V power, it also meets RoHS/WEEE standards and includes a 2-year limited warranty. For conference rooms, houses of worship, transit hubs or control rooms looking to improve accessibility and streamline AV management, the DL207 SYS is a professional, network-ready induction loop amplifier—contact sales to configure your deployment or add it to your system design.
