The Ravel RE-2AS is a compact EN 54-16 certified public address and voice alarm system that ensures a fast, safe and controlled emergency evacuation. RE-2AS is the most versatile and cost effective PA/VA system, thanks to its cutting-edge features, excellent audio quality and flexibility in minimum space. It has 2 class D amplifiers, 6 zones, 3 audio inputs, 6x6 audio matrix, DSP and LCD display. The system can be configurated without software or PC, thanks to the Plug & Set mode for PA/VA. Audio inputs and automatic mixing allow high versatility for PA use in small installations. RE-2AS has an EN 54-4 battery charger and can operate with one 12V battery. This feature and its advanced power saving control reduce maintenance costs to the maximum. A Wall & Rack innovative design makes RE-2AS suitable for wall mounting and rack integration.
