The Micro AMP 1 are amplifiers for loudspeakers and headphones. They are compact, powerful and versatile.

Combine the sound system of a space with proximity listening

Add sound to a place with simple speakers thanks to the loudspeaker amplifier with comfortable power to play brackground music or messages in an exhibition space, a hall, a gallery …

The headphone output allows to hear the same signal as on the loudspeaker output, with a separate volume control. For example, it is possible to play the sound through loudspeakers in a room and to listen to the signal in a headset in a control room or in the headphones of a visitor.

The Micro AMPs deliver uncompromising audio quality across the entire bandwidth. The bass is powerful and the treble accurate.

Sensor-controlled volume and acoustic correction

The Micro AMP 1 offers an input contact or an RS-232 control to modify the volume according to an event. Example: in a room without visitors, music is played at a low level to attract attention. Thanks to a presence sensor such as the ID-AL IRPad, when detecting a presence, the sound increases or decreases to a preselected level, then returns to its previous level when the presence is no longer detected.

The Micro AMP 1 also offers audio processing with a bass/mid/treble corrector, trigger time management, fade time between 2 volume levels and input gain control.

Designed and manufactured in France, the range of Micro AMP 1 has a 3-year warranty.

The Micro AMP 1, simple solutions for proximity listening and sound reinforcement:

  • In museums, integrate loudspeakers and headphones for animation or showcasing.
  • Audio POS, terminals…
  • Create zones with automatic volume management.
  • Adjust the sound according to your environment with the integrated audio processing.
