Atoll Evolution Integrated Pre-Amplifier - Made in France
Overview
The PR300 EVO belongs to ATOLL’s “Evolution” range of preamplifiers. It has a wide range of combinations with considerable improvements.
Features
- 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).
