The PR300 EVO belongs to ATOLL’s “Evolution” range of preamplifiers. It has a wide range of combinations with considerable improvements.

  • Front panel in 8 mm brushed, micro-blasted and anodised aluminium, high-precision engraving.
  • 1,5 mm steel chassis.
  • Two toroidal transformers of 10 VA each for the stages.
  • One 3,2 VA linear transformer (digital stages).
  • One 5 VA low consumption transformer (control logic).
  • High-quality shielded MKP link capacitors.
  • Double mono and integral symmetrical structure:

– Two independent symmetrical stages for each channel.
– One stereo attenuator per channel (with switched resistors).

  • Audio stages with bipolar transistors, perfectly symmetrical structure, polarised in class A, very low feedback rate.
  • Precise adjustment of the balance, possibility to memorise it.
  • Possibility of choosing the standby mode: Low consumption or preheating.
  • High contrast OLED display: ON or OFF mode (after 5 seconds of inaction).
  • ATOLL global remote control delivered as standard.
