Repeat visits don't happen by accident...
Every repeat visit, every referral, every five-star review is earned by an experience that felt right from start to finish — including the atmosphere. Southwestern Microsystems has been building commercial audio systems for salons, spas, tanning studios, and medical offices since 2002. Not because it's the biggest market — because it's the one we understand better than anyone else.

Data Protection System (DPS)
For businesses with multiple tanning beds:When a power problem hits, it can cascade across your equipment and knock out beds across your entire floor at once. Our DPS prevents that chain reaction, so one problem stays one problem instead of taking everything down with it.
