For a long time, installers worldwide have been looking for a professional integrated amplifier for use in commercial environments, boardrooms or small businesses. An affordable but yet professional unit, designed for 24/7 operation.

Their search arises from the fact that many small business owners often frown upon professional sound systems. They consider a traditional combination of pre-amplifier - amplifier - sources cumbersome, and fear it will burden their budget. All too often, the result is a consumer minisystem, sadly sitting on a shelf somewhere behind a store counter.

The unit can operate with one stereo zone, two volume-linked zones, or two individual-volume zones.
