A public address system (PA system) is an electronic system comprising microphones, amplifiers, loudspeakers, and related equipment. PA systems are used in any public venue that requires that an announcer, performer, etc. be sufficiently audible at a distance or over a large area. Typical applications include sports stadiums, public transportation vehicles and facilities, and live or recorded music venues and events.
High-quality public address and voice evacuation systems are essential for dealing with security and safety challenges. To be truly effective, a public address and emergency sound system must deliver exceptional performance and reliability. The company has provided systems and components for major transportation terminals, houses of worship, public buildings, office buildings, schools and shopping malls around the world.

Technical highlights
Dynamic source routing
Dynamic source routing and intelligent amplifier switching significantly reduce the number of required amplifiers. This reduces the initial investment and minimizes the power consumption
IRIS-Net integration with standard and advanced configuration
PAVIRO includes a wizard for fast and easy configuration. In addition, the expert configuration provides a unique Task Engine programming environment for further options and flexibility.
Combined or split router loudspeaker line blocks
Each router can handle up to 24 loudspeaker lines, using just one type of amplifier. This creates extreme adaptability in the system. Power load sharing over the zones (from 2W to 500W) makes the system even more flexible – allowing combinations of low and high power zones within a router.
Professional Sound quality
Wide bandwidth (50Hz-20kHz), dynamic system range with more than 100 dB Signal-to-Noise Ratio and very low channel crosstalk together deliver excellent audio quality.
