IN300 Black

The ATOLL IN300 is an analog amplifier in its purest form.

Made up of two separate mono power amplifiers, each with six MOS FET's transistors in combination with a total of two heavy toroidal transformers together form the basis of this very solid stereo amplifier.
No rocket science but purely how an analog amplifier should be built, in a class of its own, stable at any power demand, defined in its sound, makes this IN300 a pleasure to listen to.

ATOLL IN300 High End stereo amplifier with D / A converter and Bluetooth.

The ATOLL IN300 is very solidly built, with 15 kg of mass it is certainly not a light amplifier, with its width of 440 mm the IN300 looks very large.
The front is made of solid brushed aluminum, mechanically processed and then anodised in black or silver.
The beautiful OLED display comes out straight, subtle and clear.

The High End speaker connections on the left and right are of an extremely high quality.
ATOLL has certainly not cut back on this and that makes the user very happy.

ATOLL has of course also thought of the analog user who would like to make tape recordings;
A Tape input and output to which you can connect your cassette deck or tape recorder without any problems.
Plus 4 extra analog inputs of which 1 input can be upgraded to an MM or MM / MC turntable input;

Record player P100 MM / MC board € 115.00 extra

In the digital field, the ATOLL IN300 of course does not lack anything, including D / A converter 2 x coaxial, 2 x optical, USB, Bluetooth 


– converter: AK4490: S/N: 120 dB dynamic 120dB.
– DSD: 2.8MHz and 5,6MHz.
– PCM from 16 bits to 32bits up to 384 kHz on USB (asynchronous).
– Up to 24Bits 192kHz on optical and coaxial.
– USB converter XMOS: XUF208 with specific program for PCM and DSD specially developed for ATOLL.
