PR300 Evolution

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

  • 8 mm brushed, micro-blasted and anodized aluminum front panel, high-precision engraving.
  • 1.5 mm steel chassis.
  • Two 10 VA toroidal transformers each for the audio stages.
  • A 3.2 VA linear transformer (digital audio).
  • A 5 VA low-consumption transformer (control logic).
  • High-quality and shielded MKP link capacitors.
  • Integral dual mono and symmetrical structure:
              – Two independent symmetrical stages for each channel.
              – One stereo attenuator per channel (with switched resistors).
  • Audio stages with bipolar transistors with perfectly symmetrical structure, polarized in class A, very low feedback rate.
  • Precise balance adjustment, possibility of memorizing it.
  • Possibility of renaming the inputs.
  • Possibility of choosing the standby mode: Low consumption or preheating.
  • High-contrast OLED display (on or off mode after 5 seconds of inactivity).
  • ATOLL global remote control supplied as standard.
  • The PR300 EVO is compatible with DA100 and DA200 boards (optional): 
              – DA100 and DA200. 
              – P50 and P100.
