ATI AT6005 Power Amplifier: The Ultimate Power for an Exceptional Audio Experience

The ATI AT6005 power amplifier is an audiophile gem designed for discerning music lovers seeking an extraordinary listening experience. With its innovative design, superior performance, and impressive power, this amplifier is destined to outclass the competition on all fronts.

Symmetrical Design for Unparalleled Audio Quality

The ATI AT6005 power amplifier utilizes a fully symmetrical Class A/B design, offering perfect symmetry and optimal balance of audio signals. By using two toroidal transformers and independent secondary windings, each channel benefits from separate power supplies, ensuring accurate and faithful sound reproduction.

ATI Signature Series: A Step Towards Excellence

The dual mono amplifiers in ATI’s Signature Series are renowned for their exceptional quality. They employ a symmetrical circuit configuration, combining a single input stage with bi-differential output stages. This innovative approach retains the advantages of symmetrical designs while reducing noise by half. The result is cleaner and more dynamic audio reproduction.

Ultra-Fast Response for Total Immersion

The Signature Series amplifiers use current feedback instead of voltage feedback, giving them an ultra-fast response and virtually unlimited slew rate. This characteristic enables them to accurately reproduce the subtleties of today’s music and film recordings. You can fully enjoy every note, every nuance, and immerse yourself in an immersive audio experience.

ThermalTrak: Cutting-Edge Technology for Optimal Performance

The Signature Series amplifiers incorporate ThermalTrak output devices, which provide real-time temperature sensing with the output transistor. This advanced technology enables precise and stable bias performance. Combined with dual DC servos, it reduces DC offset at the output to insignificant levels. You can enjoy exceptional audio quality without undesirable distortion.

Raw Power for a Dynamic Audio Experience

The 6000 series amplifiers deliver a 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 also deliver 450 W RMS into 4 Ω under the same conditions. ATI stands out by adhering to the FTC measurement standard, ensuring reliable performance that meets specifications. With a signal-to-noise ratio of -128 dB at full power, these amplifiers can reproduce the entire dynamic range available on today’s high-definition recordings.

Built-in Protection for Peace of Mind

The AT6000 series amplifiers feature comprehensive protection against overloads, DC faults, overvoltage, and overheating. You can use your amplifier with complete peace of mind, without fear of damaging your speakers or audio equipment. Additionally, the proprietary soft-start circuit prevents any power-on surges, preserving the longevity of your amplifier.

Elegant and Functional Design

The design of the ATI AT6005 power amplifier combines elegance and functionality. Its sleek front panel features a single power switch. The soft-start circuit gradually powers on the amplifier, avoiding voltage spikes. Once the startup process is complete, the button fully illuminates, adding an aesthetic touch to your audio system.

Comprehensive Connectivity for Optimal Integration

On the rear of the ATI AT6005 amplifier, you’ll find a full range of connections to meet all your needs. It includes an unbalanced RCA input and a balanced XLR input, providing the flexibility to connect your preamplifier or preferred audio source. Additionally, an input selector switch allows you to easily toggle between different sources. Each channel is equipped with a pair of gold-plated speaker outputs, ensuring a solid and reliable connection. The amplifier’s rear panel also features a trigger to automatically power on your amplifier when triggered by your preamplifier, as well as a gold-plated chassis ground lug, fuse holder, and an AC inlet for the detachable power cord.
