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.
- The PR300 EVO can accommodate the following optional boards:
– DAC boards: DA100 and DA200.
– PHONO boards: P50 and P100 (can be combined with DAC boards).
