IN400SE Black
Description
Stereo amplifier, power 160 W per channel (8 Ohms), 300 W per channel (4 Ohms). Frequency range 5 Hz - 100 kHz, sensitivity 100 mV, input impedance 220 kOhm. Balanced XLR input, USB connector. Remote control included.
The integrated stereo amplifier Atoll IN 400 is part of the Gamme series of High-End components. This unit features uncompromising quality construction and audiophile-grade sound.
The amplifier is manufactured on a 2 mm thick steel chassis, which provides reliable protection of the electronic circuit from external mechanical influences. The front panel of Atoll IN 400 is made of a 10 mm thick aluminum plate, and has an unusual shape, as well as its body. It is determined not only by following the general stylistic concept of the series, but also by the fact that it is capable of providing better resistance to the spread of vibrations. Radiators for cooling the output transistors have a special geometry for the most efficient heat removal and ensure reliable operation of the amplifier at any listening volume.
The Atoll IN 400 amplifier circuit is designed according to the dual mono principle, with complete separation of stereo channels. The amplifier has independent volume controls for each channel, as well as a dual star ground circuit. Only selected audiophile-grade components are installed in the audio path of the amplifier, and the toroidal transformer in the power supply has a power of 1015 VA. The total capacitance of the filter capacitors is 93400 μF. At the output of each amplifier, four high-current transistors are mounted (in each arm).
Atoll IN 400 develops 160 W per channel when connecting 8-ohm speakers, increasing this figure to 2 x 300 W when driving 4-ohm speakers. The device has four line inputs, an input/output for connecting a recording device, and a By-Pass input for working as part of a multi-channel surround sound system. There is also one balanced XLR input and a preamp output. High-quality gold-plated screw connectors are provided for connecting speaker systems. The Atoll IN 400 amplifier is also equipped with a USB input for connecting to a PC. Optionally, an MM/MC phono stage board can be installed in the device.
Atoll IN 400 is equipped with a full-featured remote control and is equipped with a display with a switchable light color that displays the main modes of its operation.
