ATOLL PR300 Evolution Preamplifier

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.
