A Small-size Amplifier creating High-End Sound

Audio amplifiers do not need ten times more power than actually necessary and weigh several kilograms. Due to its high efficiency and its exceptional dynamic range, the ABACUS Ampino with its 50 W RMS power proves to be the ultimate amplifier, not only for small to medium-sized loudspeakers.

Features:

  • Awards: fairaudio’s Award 2008 und fairaudio’s Award 2017
  • Since version ”15” with Dolifet amplifiers
  • Combines the advantages of tube- and transistor amplifiers
  • Input impedance at output: 0 Ohm
  • Virtually infinite damping
  • Extremely high efficiency
  • Linear Integrated Amplifier
  • Output signal provides zero-loss negative feedback: connected loudspeaker is 100% controlled by the amplifier
  • Connected loudspeakers are linearized
  • No post-oscillations of the membrane
  • Protection for loudspeaker and amplifier
  • Precision potentiometer (Alps RK27)
  • Stable aluminum chassis
  • NEW: Noise suppression during switch-on
  • Blue LED indicating operation
  • Combines advantages of tubes and transistors

The ABACUS Ampino and the corresponding preamplifier ABACUS Prepino are the perfect combination. Both provide high-end sound at a moderate price.

The Ampino is delivered in a hard-top case and comes with a power cord and a user manual.

 

The ABACUS Ampino is very similar to its larger equivalent, the ABACUS 60-120C, offering the same charge capacity.

The ABACUS Ampino comes with volume control via an ALPS precision potentiometer. This even allows the Ampino to be used without any preamplifier, if only one audio source is used and a remote control is not required.

When it comes to sound, the ABACUS Ampino is fully equivalent with the larger ABACUS Amplifiers. The unique ABACUS technology allows the Ampino to control the loudspeaker over the whole dynamic range.

The maximum output power of the ABACUS Ampino is limited only by the smaller toroidal transformer, delivering 50W of electric power. Still, it offers sufficient power to customary loudspeakers, allowing for high quality sound at normal sound pressure levels and beyond….

Due to the zero-loss negative feedback the output voltage is always in phase to the input voltage, regardless of the load at the output stage of the amplifier. The typical post-oscillations of a loudspeaker after excitation are therefore eliminated, which the most precise bass response and most realistic sound images, possible.

The amplifier output of ABACUS amplifiers is independent of the load, which includes the cables and connectors as being part of the load. Only the cross-section of the cable remains an important factor. The cable material is not important; as long as it is electrically conducting. Using ABACUS amplifiers, the money, which would be spent on advertised “magic” cables, is better invested in a number of new music CDs.

Originally designed for the small hi-fi system in the home office or dining room, the ABACUS Ampino is also used in living rooms by an increasing number of hi-fi enthusiasts. In case that the Ampino exceeds its power capabilities, a overload protection prevents both the amplifier and the loudspeaker from being damaged.
