Amplifier ATI AT1805

ATI name is an abbreviation of Amplifier Technologies Inc. Indeed, the company narrowly specialized in electronic components for home theater, and, except for amplifiers, produces only AV-processor. But the range of its amplification technology is very wide, and you can easily find the necessary components to equip the cinema of any size and complexity. All products are designed not only to ATI, but also produced in Los Angeles, that in our time has become a rarity. A series of multi-channel power amplifiers 180x includes six devices with different number of channels of amplification - from two to seven, which is reflected in the last digit of the index on the model. For obvious reasons, we chose to test the five-channel option. Corps uniform for all the family of amplifiers, which explains the impressive size of our sample. On the front panel of the black aluminum located close company logo, rocker power switch and three LEDs - Standby, On, and Peak. The housing is closed with a metal lid plurality of ventilation holes not only on, but also on the sidewalls. In directly behind the facade mounted two huge toroidal transformer. One feeds three channels of amplification and the other respectively, two. No special measures for screening these giants are not provided. Left along the side wall has a small board machine power management component, and the rest is given an inner space monoblocks amplifiers. Each is equipped with its own power supply, which minimizes the effect of the amplifiers at each other. The entire surface of the board is closed finned heat sink output stages performed on twelve transistors Toshiba. If you fill all available space inside the case, then there will just seven of the amplifier modules, and in our case, two slots are free. The abundance of the vents in the lid and bottom, as well as a large area of the radiator cooling eliminates the need for mechanical ventilation. The design of the model produces so fundamental impression that resembles military technology, designed for a direct hit by an artillery shell. To connect with AV-processor or receiver has only connectors RCA - a balanced switching firm saved up for amplifiers of the older series. However, the connectors themselves are very high quality, everything is as it should be - secure attachment, gilding contact surfaces. Acoustic same terminals quite ordinary plastic. Pay attention to the non-standard power outlet mounted on the body, - the earth pin in it is not vertically as two adjacent and horizontally. Included with the unit is a good power cord, so that any problems should not be, but who want to experiment with network cables this feature you need to consider.

The first impression of solidity and impressiveness not deceived - accompanying movie shows the hurricane power head and a huge reserve of power. Soundscape drawn large confident strokes, but also the small details in this maelstrom is not lost. With the creation of the illusion of presence, so necessary in a home theater, ATI AT1805 handles great - during the shootings and then have to bend down to around whistling bullets, and gnashing and crashing crushes in car accidents iron sneaks up to the livers. In the performance of musical compositions unit retains its solid sound handwriting, especially well succeed his extensive work. However, the chamber material sometimes there is some simplification of the sound image.
