Founded in 1983 in Nordenham, Northern Germany, ABACUS electronics UG is a small, family-owned company specializing in manufacturing electrotechnical products primarily for HiFi, studio, and public address sectors. Headquartered at Bahnhofstraße 39a, D-26954 Nordenham, the company has built its reputation over 40+ years developing proprietary 'Dolifet' (Drain-Output Load-Independent Field Effect Transistor) amplifier technology that allows circuit advantages of tube technology without using actual tubes. This innovative approach uses field effect transistors 'backwards,' making the drain connection load-independent and optimally suited to drive loudspeakers with exceptional control and dynamics. ABACUS produces a comprehensive range of audio equipment including active speakers, preamplifiers, power amplifiers, and audio streaming devices, all incorporating their signature Dolifet technology. Their product lineup includes the flagship 60-120D Dolifet power amplifier (fourth generation), compact Ampino 15 Dolifet amplifier, and popular speakers like Mirra 14/15 and the C-Box 3 studio monitor, which has become the number one studio monitor in Germany. The company's Pivota 42 monitors are permanently installed at the legendary Hansa Studios in Berlin, demonstrating their professional recognition. Operating with close partnerships with primarily German and EU suppliers, ABACUS maintains in-house manufacturing in Germany while focusing on technically relevant components and avoiding audiophile esotericism, establishing themselves as a respected name in the professional and high-fidelity audio markets.
