AtlasIED WTSD-PWHUB WTSD Power Hub DC Power Injector, Audio Interface

Streamline control and protection at the amp rack with the AtlasIED WTSD-PWHUB power hub and audio interface. Designed to sit at the head-end for WTSD wall-plate mixers, this audio power injector centralizes relay control, emergency audio mute and gain headroom limiting so integrators can confidently deploy background music, paging and priority communications across campuses, schools and commercial facilities. The WTSD-PWHUB accepts a 24V DC input (power supply sold separately), offers balanced audio output for clean signal transmission, and delivers wideband audio performance up to 20 kHz. Built-in auto-sleep and a local System Priority latching button provide flexible room-takeover and automatic relay control, while the peak limiter helps protect high-power amplifiers and speakers from overload. Compact, rack-mountable aluminum construction makes it ideal for security, surveillance and monitoring systems as well as AV installations. For integrators needing robust head-end control and device integration for WTSD mixers, the AtlasIED WTSD-PWHUB is a reliable choice—contact your AtlasIED reseller or add it to your system design today.
