| Content | For a long time, installers worldwide have been unhappy with consumer electronics and they were looking for a professional integrated amplifier for use in commercial environments, boardrooms or small businesses designed for 24/7 operation. Therefore Apart developed the CONCEPT1, a stereo or two mono channel (2 x 80 watts @ 4 ohms) amplifier for small and medium-sized projects.
This CONCEPT1 2-zone integrated stereo amplifier can operate with one stereo zone, two volume-linked mono zones or two individual-volume mono zones. The unit can be controlled via RS232 what makes integration into your AV solution possible. The built-in limiters and system design guarantee a failsafe solution 24 hours a day, 7 days a week.
To make the life of the end-user as easy as can be, the CONCEPT1 has user settings and installer settings. Only the absolute
