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). ATOLL global remote control supplied as standard. The PR300 EVO is compatible with DA100 and DA200 boards (optional): – DA100 and DA200. – P50 and P100. CONNECTIVITY Inputs 1 XLR input. 5 Line inputs: AUX or PHONO (option) CD, TUNER, DVD, TAPE. 1 BY-PASS input. Outputs 2 Line outputs. 1 XLR output. 1 12V Trigger output. Possibility of adding the DA200 digital board (optional): 2 Optical inputs (24 bits/192 kHz). 2 Coaxial inputs (24 bits/192 kHz). 1 Asynchronous USB input (24 bits/384 kHz) & DSD (up to 256). 1 Bluetooth input.
