Description
The WTSD-PWHUB is engineered for seamless integration with AtlasIED WTSD wall plate mixers at the amplifier rack, substituting the WTSD-PWBOB when enhanced headroom control and external device integration are essential. This product delivers an emergency audio mute function for fire safety systems and incorporates two NO / NC relays. One relay is automatically engaged by the auto sleep function, while the other can be manually activated via a local latching “System Priority” button on the WTSD-MIX31K or WTSD-MIX41K. These relays can be configured to power the amplifier rack On or Off using the auto sleep function. The system priority button allows for the prioritization of a room by muting background music and paging across the entire building when the room is occupied. Gain headroom limiter settings and indicators are available to manage the balanced audio feed before it reaches the amplifier rack, especially when multiple WTSD units are connected to a single bus. The limiter can be adjusted to safeguard high-power systems from amplifier overload and potential speaker damage. Note that a 24VDC power supply is required and must be sourced separately.
