Description
Need to extend your paging system into a remote area without running a separate amplifier? The Viking SA-1H is a self-amplified 5-inch paging horn that includes a built-in 1.5-watt power amplifier, an infrared remote control detector, and an integrated digital volume control — all in one compact, easy-to-mount unit.
The SA-1H uses Viking's proprietary two-wire protocol that combines 40VDC power and audio on the same wire pair, eliminating the need for a separate power run. It's designed for direct connection to the Viking SA-25 Self-Amplified Paging System, making it simple to add coverage zones without additional amplifier rack space. The infrared remote control detector lets you adjust volume from across the room without touching the horn.
Our Expert Take: The SA-1H is a clever solution for extending PA coverage into secondary spaces — back offices, warehouses, stairwells, or remote rooms — without running power separately. The built-in IR volume control is a genuine convenience for spaces where the horn is mounted high or out of easy reach. Make sure you're already running the SA-25 system before adding SA-1H units.
