AT1800 Series

The AT1800 shares key hallmarks with its larger siblings, the AT2000 and AT3000’s. The AT1800 is available in 6 configurations from the AT1802 2-channel model to the AT1807 7-channel version. Power is conservatively rated at 180 Watts RMS/channel into 8 Ohms from 20Hz to 20kHz with no more than 0.03% THD and I.M. distortion. Each model comes equipped with two toroidal transformers, a detachable IEC power cord, optically coupled protection circuits, soft-start circuit and convection cooling eliminating the need for fans. Units can even be upgraded at the factory to add additional channels (up to 7).

AT2000 Series

ATI’s "Pure Balance"® technology introduces a range of models that feature true differential design; balanced from input to output. This design allows the quietest and purest reproduction of the audio signal. In the AT2000 series, power output for each module is 200 Watts RMS/ channel into 8 Ohms from 20Hz to 20kHz with no more than 0.03% THD and I.M. distortion with 300W RMS/channel available at 4 Ohms.. The AT2000 series amps are available in 2 to 7 channel configurations. Each model in the series comes standard with 2 massive toroidal transformers and can be upgraded at the factory by changing power transformers, adding power modules and a new rear panel. The maximum is 7 channels.

ATI’s "Pure Balance"® technology introduces a range of models that feature true differential design; balanced from input to output. This design allows the quietest and purest reproduction of the audio signal. 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 into 4 ohms with the same conditions. Each model in the series comes standard with 2 massive toroidal transformers and can be upgraded at the factory by changing power transformers, adding power modules and a new rear panel. The maximum is 7 channels.
