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

Atoll's 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.

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.

OPTIONAL BOARDS AVAILABLE

1 Digital board (of your choice):

DA200
2 Coaxial inputs (24 bits/192 kHz)
2 Optical inputs (24 bits/192 kHz).
1 Bluetooth receiver.
1 USB-B input: PCM & DSD.
DA100
2 Coaxial inputs (24 bits/192 kHz).
2 Optical inputs (24 bits/192 kHz).

———————————

1 Phono board on the AUX input (of your choice):

P100 (configurable MM or MC).
P50 (MM).

Even if these boards can be installed by the user at any time, it is preferable to install them at the time of purchase by your authorised dealer.
