The active VPA-AR30 and VPA-AK30 models have a built-in power amplifier and work as standalone sound points — with no connection to an external amplifier. All they need is an input audio signal from any source (a microphone, a player, a security-system output) and power. This is the solution for sites where running a 70/100V line is impossible or not cost-effective: remote gatehouses, temporary sites, facilities with no existing PA system, and security posts.
The VPA-AR30 is an active horn loudspeaker with a built-in amplifier and audio-line input: 30 W, 250 Hz – 13 kHz, IP66, 106 dB, 205 × 285 × 280 mm, 1.86 kg. Self-powered and weatherproof, it plays announcements straight from an audio source — ideal for IP-camera voice deterrence and perimeter security.
The VPA-AK30 is an active PA column loudspeaker with a built-in amplifier: 30 W, 80 Hz – 20 kHz, IP65, 93 dB, 490 × 160 × 115 mm, 3.5 kg. Weatherproof and self-powered, it plays directly from an audio source for outdoor public address and perimeter security.
Active loudspeakers are the best choice for building local point-to-point PA systems, for retrofitting sites without an existing system, and for temporary work sites and security posts. On sites that already run a working VPA public address system, adding extra active points is usually not worthwhile — passive models of the same power are cheaper.
