Power up with peace of mind: ULTRA-X20’s built-in IntelligentAC technology auto-selects correct operating voltage, suppresses high voltage transients, filters EMI, and provides soft-start power-up. The ULTRA-X20XP loudspeaker variant incorporates IntelligentDC technology, which receives balanced audio and DC power from a single composite cable—eliminating the need for conduit and allowing for longer, lighter-gauge cable runs.
