LSC22

Functionality and flexibility for airborne loudspeaker systems.

AEM’s industry-leading LSC22 is the most advanced controller available. We qualified it to DO-160G and DO-214 to assist with integration and designed it for pin-for-pin replacement of the AA21, eliminating the need to change wiring harnesses.

Our LSC22 is compatible with both legacy AEM and NAT public address equipment, as well as our new LSA series product line; it also provides wail and yelp siren types which can be customized to suit specific operational requirements.
