Atoll Electronique PR300 Evolution

The PR300 EVO preamp concentrates our know-how. This model is specially designed to meet the needs of demanding music lovers, offering unprecedented modularity and remarkable musicality. We have chosen to equip it with XLR input/output and audio stages with a fully symmetrical and dual mono structure.

• 8 mm brushed, micro-blasted and anodised aluminium front panel, high-precision engraving.
• 1.5 mm steel chassis.
• Two 10 VA toroidal transformers, one for each of 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.
