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.   

As an answer to these questions, APart has introduced Concept 1T: an affordable pro-use 100V stereo integrated amplifier. The unit can operate with one stereo zone, two volume-linked zones, or two individual-volume zones. The unit also offers versatile user and installer settings, RS-232 control, gain-adjustable line-inputs, a MIC-input for paging, and many other professional features.    

Three operating modes  

Concept 1T can operate with 1 stereo zone, 2 volume-linked mono zones or 2 individual-volume mono zones.  

User controls: music volume, mic level, treble, bass. The controls can be locked.
