AtlasIED Z4-B 4-Zone High-Definition Acoustical System

Deliver reliable speech privacy, paging and background music with the AtlasIED Z4-B 4-Zone High-Definition Acoustical System — a Pro Mass Notification solution built for integrated security and facility audio. The Z4-B combines proven Chanaud sound masking filters with practical paging/BGM features so you can protect confidential meetings, reduce distraction in open-plan areas, and manage mass notification from a single unit. The system supports four independent zones with 120W total output (4 x 30W) and 70V outputs, and can mask spaces up to 14,000 sq. ft. in indirect-field mode. Installers benefit from flexible mounting (in-wall, surface, or rack) and secure front-panel wiring that simplifies commissioning and remote monitoring. For controlled environments, Speech Privacy Enhancement boosts privacy on demand via hardwired switch, mobile app or optional wireless control—useful for conference rooms, legal offices, healthcare suites and government facilities requiring higher confidentiality and monitoring. With Bluetooth streaming, mic/line paging inputs, per-zone EQ and VOX priority, the Z4-B streamlines BGM and paging while supporting security, surveillance and mass notification workflows. Specify the AtlasIED Z4-B for turnkey sound masking and compliant mass-notification performance.
