Thanks to its powerful range of features, PAVIRO not only answers an extremely wide variety of application requirements, it also delivers best-in-class performance in quality, ease of installation, and versatility.

Dynamic source routing

Dynamic source routing and intelligent amplifier switching, significantly reduces the number of required amplifiers. This reduces the initial investment and minimizes the power consumption.

Combined or split router loudspeaker line blocks

Each router can handle up to 4000W, in one or two channels on 24 loudspeaker lines, using just one type of amplifier. This creates extreme flexibility 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.

IRISNet 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.

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.

AC Operation

• AHUJA introduces CCS-2300, a two-way counter communication system, exclusively designed for easy and effective conversation across counters with transparent security barriers. It consists of an attendant unit, a customer unit and a power supply unit, which are easy to install and simple to connect through dedicated cables as supplied with the system.
• Unique design, pleasing aesthetics & rugged construction.
• Two-way, hands-free communication. 
• Easy, hassle-free installation.
• Compact & elegant table top attendant unit with 20” long gooseneck microphone for strain-free usage.
• A 3.5mm jack socket is provided for connecting a headband microphone like Ahuja HBM-50. This is useable by the attendant as an alternate to the fixed gooseneck microphone.

A public address system (PA system) is an electronic sound amplification and distribution system with a microphone, amplifier and loudspeakers, used to allow a person to speak to a large public, for example for announcements of movements at large and noisy air and rail terminals or at a sports stadium or amplify other audio content, such as recorded music or the live sound of a band. The term is also used for systems which may additionally have a mixing console, and amplifiers and loudspeakers suitable for music as well as speech, used to reinforce a sound source, such as recorded music or a person giving a speech or distributing the sound throughout a venue, building or area.

Simple PA systems are often used in small venues such as school auditoriums, churches, and small bars. PA systems with many speakers are widely used to make announcements in public, institutional and commercial buildings and locations, such as schools, stadiums and large passenger vessels and aircraft. Intercom systems, installed in many buildings, have both speakers throughout a building, and microphones in many rooms allowing the occupants to respond to announcements.
