ADM22 mk2

Active FIRTEC reference monitorsuitable for all applications




KSdigital manufactures each of its loudspeakers by hand in its factory Saarbrücken/Germany. Each loudspeaker is measured individually (IFM) and linearized in frequency and phase. This ensures the unrivalled correct reproduction of the music signal.


With the introduction of the first FIRTEC controlled monitor KSdigital changed the kind of building professional monitors. The traditional way is the linearisation of the ampitude response. With the FIRTEC(TM) digital signal processing our attention is to reproduce a correct impuls response. This FIR-equalisation means a flat ampitude response and a flat phase response, which means a correct signal with all details in tone and time and stereo image. The products of the A-Line are the state of the art monitors for all applications: the bridge monitor in nearfiled application as well as the In-wall-solution for the big control room.

The ADM22 represents a complete upgrade of the legendary ADM 20, the first digital, linear phase studiomonitor worldwide. In this upgrade, all important reproduction functions of the ADM20 were taken over andfitted to the new cabinet. Therefore the ADM22 also processes the signal digitally with its own DSP platform.

Our patented FIRTEC system filters ensure a linear phase, and a correctly timed reproduction across theentire frequency range. The wave guide eliminates the effect of the cabinet edges and linearizes not only theprocessing of the digital signal but also the frequency characteristics. The 1” high frequency ring emittersensure low distortion even at high volumes. The 8” carbon chassis (made in Germany) with its optimized stiffbut low weight membrane (F1 material), prevents a break-up into partial oscillations at high volumes, so thatthe compact ADM22 represents a full value monitor for all applications. The 24 bit / 192 Khz DA convertersupplies the analogue output stage with its special audio 180W (RMS) transistors.

The optional digital input (bypassing the DA converter) facilitates a direct connection to the digital work stationor master machine. Three freely configurable peak-EQs as well as high and low shelving controls permit anoptimized adjustment to the listening position in a studio. These as well as all other parameters, such as vo-lume or delay can be comfortably adjusted with optional FIR-Wlan software either from a tablet, smartphoneor with the hardware remote control RC-100.
