ATI AT6006 Power Amplifier: Ultimate Power for an Exceptional Sound Experience

The AT6006 amplifier uses a fully balanced Class A/B design, providing the perfect balance between efficiency and sound quality. To ensure a stable and clean power supply, this amplifier features two toroidal transformers and independent secondary windings, offering separate power supplies for each channel. This eliminates unwanted interference between channels, ensuring clear and accurate sound reproduction.

Signature Series: Excellence and Optimal Performance

ATI’s Signature Series dual mono amplifiers stand out with their balanced circuit configuration. This design approach maintains the benefits of balanced designs while reducing noise by half. Additionally, these amplifiers use a single input stage with bi-differential output stages, enabling faster response and virtually unlimited slew rate. As a result, they can faithfully reproduce the most demanding musical and cinematic recordings.

Optimized Performance with ThermalTrak Output Devices

Signature Series amplifiers incorporate ThermalTrak output devices, providing real-time temperature sensing with the output transistor. This technology enables precise bias performance, reducing DC offset to insignificant levels thanks to dual DC servos. You can enjoy exceptional sound quality without distortion or unwanted interference.

Raw Power and FTC Compliance

The 6000 series amplifiers deliver an impressive rated power of 300 W RMS from 20 Hz to 20 kHz, with a maximum THD of only 0.03% into 8 ohms, all channels driven. They even deliver 450 W RMS into 4 Ω under the same conditions. By adhering to the strict FTC measurement standard, ATI ensures reliable and realistic performance. 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.

Protection and Reliability

The AT6000 series amplifiers feature comprehensive protection against overload, DC faults, overvoltage, and overheating. Your amplifier is safeguarded from potential damage, ensuring long-term durability. Additionally, the proprietary soft-start circuit prevents power-on surges, ensuring a smooth startup of your audio system.

Sleek and Functional Design

The aesthetics of the ATI AT6006 amplifier are both understated and elegant. The front panel is minimalist, with a single power switch. The soft-start circuit gradually powers up the amplifier to prevent any surges. Once the startup process is complete, the button fully illuminates, adding a pleasing visual touch to your audio system.

Complete Connectivity

On the back of the AT6006 amplifier, you will find a wide range of connections. These include an unbalanced RCA input, a balanced XLR input, an input selector switch, and a pair of gold-plated speaker outputs for each channel. Additionally, the amplifier is equipped with a trigger, allowing it to automatically turn on when your preamplifier is powered on. You also have a gold-plated chassis ground terminal, a fuse holder, and a power socket for the detachable power cord.

Rack Mounting

If you wish to integrate the AT6006 amplifier into a standard 19-inch rack, ATI offers an optional rack kit for convenient and secure installation. This allows you to optimize the space for your audio equipment while benefiting from the exceptional performance of this amplifier.
