The PowerChiton series of weatherproof amplifier modules represent a new approach to outdoor audio systems. Combining a high performance, passively cooled amplifier with a IP66 rated, low-profile enclosure, the PowerChiton offers the system installer or designer a new solution for the problems of distributed outdoor audio system design.

Each PowerChiton monoblock amplifier module is capable of powering an @ two-Ohm load and therefore can drive one, two, or three eight-Ohm loudspeakers. Due to the efficient design of the amplifier module, only a passive radiator is needed for cooling and there are no moving parts in the module, reducing failure points.

While they were optimized for use with the Technomad Vienna, Noho and Berlin weatherproof loudspeakers, the PowerChiton can be used with any eight or four ohm loudspeaker.

The PowerChiton base model ships with two line-level inputs, which can be independently adjusted by an internal mixer. The PowerChiton has available expansion options enabling it to work on an Ethernet network (accepting any bit-rate MP3 format audio for VOIP or Audio-Over-IP applications), RDL™ Twisted Pair installation, or FM wireless distribution system. When combined with Technomad’s wireless transmitter, the PowerChiton system provides an unrivaled way to distribute audio and amplify it at maximum quality.

The PowerChitons can be wall-mounted with the included mounting feet. Pole-mount adaptors are also available as well as hardware allowing the modules to be installed on the back of the associated Technomad loudspeakers.
