Eaton / Wheelock SPB-320 Audio Power Booster 320W

Product Description

The EATON / WHEELOCK SPB-320 is a 320-watt audio power booster designed for voice evacuation systems. It amplifies audio signals to support mass notification and emergency communication across large or multi-zone installations. The SPB-320 is built for life safety applications where reliable, high-output audio distribution is critical. Licensed fire alarm technicians and low-voltage contractors are the primary installers of this unit, typically integrating it with a listed voice evacuation control panel to extend audio coverage throughout a facility.

The SPB-320 is used in commercial and industrial voice evacuation systems where additional amplification is required beyond what a base control panel can supply. It is suited for large buildings, multi-floor facilities, or campus environments where distributed speaker loads demand supplemental power. This unit falls under the voice evacuation category and is sold as a single unit per order.
