Atoll Electronique PR300 Evolution Preamplifier

The Atoll Electronique PR300 Evolution Preamplifier embodies their expertise.

This model is specifically designed to meet the needs of discerning audiophiles, offering unparalleled modularity and remarkable musicality. They have chosen to equip it with XLR input/output and fully balanced, dual-mono audio stages.

Features

• Front face in 8 mm brushed, micro-bead blasted
  and anodized aluminum, 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 low power consumption 5 VA transformer (control logic).
• High-quality, shielded MKP coupling capacitors.
• Dual mono and fully symmetrical structure:
  • Two independent symmetrical stages for each channel.
  • One stereo attenuator per channel (with switched resistors).
• Bipolar transistor audio stages with perfectly symmetrical structure, biased in class A, very low negative feedback.
• Precise balance adjustment, possibility to memorize it.
• Option to rename entries.
• Option to choose standby mode: Low power consumption or preheating.
