AT3004

It is a cornerstone of ATI’s philosophy that one should only purchase as many amplification channels as one needs. The AT3004 has dual toroidal power transformers and 4 of ATI’s Pure Balance™ 300W RMS (8 ohms) modules. Should it be necessary in the future, additional modules may be added at the factory.

Designed by legendary amplifier engineer Morris Kessler, the AT3000 (and AT2000) series introduce ATI’s Pure Balance™ fully balanced, true differential circuit topology. This elegant design is basically two separate amplification circuits for each channel. One circuit amplifies the positive half of the audio signal while the other amplifies the negative half. They are combined at the output with tremendous benefits: any noise coming in from external sources, such as radio-frequency and electromagnetic interference is eliminated; amplifier noise is cut in half; the speed (slew rate) of the amplifier is doubled for better reproduction of high frequencies and better transient performance. In the AT3000 series, power output for each module is 300 Watts RMS/ channel into 8 Ohms from 20Hz to 20kHz with no more than 0.03% THD and I.M. distortion and 450 Watts RMS per channel into 4 ohms. The AT3000 is available in 2 to 7 channel configurations. Each model comes standard with 2 massive toroidal transformers and 36,000 microfards of power supply capacitance per channel. Other features making it installer-friendly are: a detachable IEC power cord, optically coupled protection circuits, soft-start circuit, 12-volt trigger, peak clipping indicator and convection cooling.

All ATI amplifiers are designed, engineered and assembled in the United States.
