Overview

The IN300 Evolution integrated amplifier features reworked power supplies, improved audio performance, and a low-power mode. DAC boards are now optional.

Our balanced MOS-FET amplifier circuits offer excellent harmonic gradients and have no memory effect. Every moment, the current is immediately delivered to your speakers. This is one of the secrets of the musicality that ATOLL amplifiers enjoy.

Highlights

8 mm brushed aluminium front panel, micro-blasted and anodised, with high-precision engraving.
2 x 150 Wrms / 8Ω.
1.5mm thick steel chassis.
Two 440 VA toroidal transformers for the audio stages plus 10 VA for the digital stages.
Soft start stage to avoid power surges.
High-end ABSOLUE CREATIONS internal wiring on the power supply side.
Filter capacitors: 12 x 6800 μF high-quality capacitors with a low ESR specifically designed for ATOLL.
High-quality, shielded MKP coupling capacitors.
Bipolar transistor and LED current sources to ensure perfect voltage stability.
Triple push-pull MOS-FET power stage.
Polarisation of the output stages in class A/B.
Possibility of choosing standby mode: Low consumption or preheating.
2 volume attenuators: 1 per channel to maintain the dual mono architecture.
Possibility to manage balance and memorise it.
Possibility to rename the inputs.
High contrast OLED display (on or off mode after 5 seconds of inactivity).
Double-sided printed circuits with nickel/gold finish.
ATOLL global remote control supplied as standard.
The IN300 EVO can receive the following optional boards: – DAC boards: DA100 and DA200. – PHONO boards: P50 and P100 (can be combined with DAC boards).

Features

DETAILED TECHNICAL CHARACTERISTICS
OUTPUT STAGES: Double mono stages with 2 toroidal transformers of 440 VA. Specific low-consumption power supply (5VA) for managing the display and logic circuits. High-quality, low-ESR filter capacitors are made to ATOLL specifications. Output stages with very little feedback provide a lot of dynamics and a very natural sound. Specific stages to avoid current peaks on ignition. High-end specific internal power wiring. INPUT STAGES: MKP Mundorf shielded capacitors. Volume by double attenuator: 1 per channel. Bipolar symmetric stages with discrete components.
