The emergency input takes priority over all other audio allowing an integrated emergency voice alarm system to be heard loud and clear. This input will work with an existing paging system, emergency paging mic, and, most importantly, a relay closure from a fire alarm system.

A Uniting Solution

To keep a church united during this pandemic, and at the same time following CDC guidelines, we started holding various Zoom events. We had a limited number of "in person" attendees plus others at home via Zoom. The Bluetooth capabilities of the amplifier provided easy connectivity with the Zoom Host's computer which allowed all of the in person attendees to hear the comments from the at home Zoom attendees. As you may know, Bluetooth connectivity can be a little unstable at times. A more stable and stronger connection would earn this unit five stars.
