Higher Power For External Amplifier System

Technomad : 08 June, 2010  (New Product)
The PowerChiton amplifier from Technomad is a weatherproof unit designed for use in outdoor distributed voice communication systems
Higher Power For External Amplifier System
Technomad is adding more power to its range of PowerChiton weatherproof amplifier modules. Able to produce 1600 watts for 8-ohm systems and 1800 watts for 4-ohm systems, the new PowerChiton4 offers more than three times the power of the current highest-power model (500 watts) in the same compact, NEMA-enclosed package.

The PowerChiton, with its IP66 protection classification, is a practically bomb-proof amplifier-in-a-shell. The IP66 rating confirms ingress protection (IP) for persons (such as electrical safety) and equipment (dust, dirt and water penetration). The latter makes PowerChiton amplifiers ideal for outdoor installations for protection against the elements. Its low-profile, modular design also gives systems designers and integrators the freedom and flexibility to place the amplifiers closer to the loudspeaker (including wall and pole-mount systems) without hassle - or to install the modules to the back of the loudspeaker with specialized hardware.

The PowerChiton4 retains all of these protection features while vastly increasing power, creating new opportunities for designers and integrators to specify and install PowerChiton amplifiers within distributed audio systems.

"We developed the PowerChiton4 in response to requests to offer a weatherproof amplifier solution for high-power applications, especially those covering large areas," said Rodger von Kries, vice president of Technomad. "This could include anything from large stadiums and train stations to campus-wide public address and emergency announcement systems. The Ethernet/Audio-over-IP-networking capabilities of the PowerChiton4 add benefits for large-area installations that are establishing zone control and tying multiple audio points to a centralized infrastructure."

All four PowerChiton amplifiers (including the 130- and 250-watt modules) are available with three networking options: Ethernet/IP, RF and twisted-pair. Its efficient design employs a single passive radiator for amplifier cooling and eliminates all moving parts to minimize failure points.

Other features include a broadcast-quality balanced line input for improved site-wide audio that is ideal for both voice (paging) and musical output; and a second input that can be used for local audio or as a secondary audio source. An internal mixer balances, improves and maintains audio levels out of the amplifier modules en route to loudspeakers.

The PowerChiton4 begins shipping in July. Technomad is also developing a powered option for its new Oslo subwoofer based on PowerChiton technology.
