ATI AT6002 Power Amplifier: A Fully Symmetrical Class A/B Design

The ATI AT6002 amplifier utilizes a fully symmetrical Class A/B design, ensuring superior amplification quality. It features two toroidal transformers and independent secondary windings to provide separate power supplies for each channel. This design eliminates interference between channels and ensures accurate sound reproduction.

Dual Mono Amplifiers in the Signature Series

ATI’s Signature Series offers dual mono amplifiers that employ a symmetrical circuit configuration. Unlike asymmetrical designs, this approach retains the benefits of symmetrical designs while reducing noise by half. The Signature Series amplifiers use a single input stage with bi-differential output stages, allowing them to respond faster and faithfully reproduce high-quality music and film recordings.

ThermalTrak Technology for Optimal Performance

The Signature Series amplifiers incorporate ThermalTrak output devices that provide real-time temperature sensing with the output transistor. This technology optimizes bias performance and reduces DC offset at the output to insignificant levels. Combined with dual DC servos, it ensures exceptional sound quality and accurate reproduction of audio signals.

Exceptional Power and Performance

The AT6000 series amplifiers deliver a rated power of 300 W RMS from 20 Hz to 20 kHz with a maximum total harmonic distortion (THD) of 0.03% into 8 ohms, all channels driven. They are capable of delivering 450 W RMS into 4 Ω under the same conditions. ATI adheres to the FTC measurement standard, ensuring performance that meets the stated specifications. With a signal-to-noise ratio of -128 dB at full power, these amplifiers can reproduce the entire dynamic range of today’s high-definition recordings.

Built-in Protection and Soft Start

The AT6000 series is equipped with effective protection against overloads, DC faults, overvoltage, and overheating. You can use these amplifiers with peace of mind, knowing they are designed to prevent potential damage. Additionally, the proprietary soft-start circuit allows the amplifier to power up gradually, avoiding any power-on surges.

Convenient and Versatile Connectivity

The ATI AT6002 amplifier offers comprehensive connectivity to meet your needs. On the rear of the amplifier, you’ll find an unbalanced RCA input and a balanced XLR input, allowing you to choose the one that best suits your audio system. It also features an input selection switch and a pair of gold-plated speaker outputs for each channel. The back of the amplifier includes a trigger that automatically turns on the amplifier when your preamplifier is activated.

An Elegant and Functional Design

The AT6002 amplifier’s aesthetic is both understated and elegant. The front panel is minimalist, featuring only a single power switch. The soft-start circuit powers up the amplifier gradually, avoiding potential voltage spikes. Once the startup process is complete, the button fully illuminates, adding a pleasant visual touch to your audio setup.

Furthermore, if you wish to integrate the AT6002 amplifier into a standard 19-inch rack, ATI offers an optional rack kit that facilitates its installation.
