Nov 6, 2026
Guangzhou, Guangdong Province, China, November 6, 2026 -- ToneWinner, a long-established Chinese audio manufacturer known for its professional cinema and karaoke amplifiers, has introduced the AT-600, the flagship of its decoder series and the company's most ambitious home-cinema processor to date. The AT-600 delivers 8K video pass-through, 16-channel immersive decoding, and — most notably — a complete Dirac Live license included at no additional cost, making professional-grade room correction accessible to a far wider audience.

A Decoder Series for Every Home Cinema
The ToneWinner AT-600 is the culmination of a decoder lineup engineered to serve the full spectrum of home entertainment, from professional cinema and karaoke systems to flagship private theaters. The series has evolved steadily with industry standards, and today spans four models:
- AT-200: 7.2.4 decoding, 4K/60Hz, HDMI 2.0, HDCP 2.2, ARC, HDR10, with karaoke support.
- AT-300: 9.3.4 decoding, 4K/60Hz, HDMI 2.0, HDCP 2.2, eARC, HDR10.
- AT-500: fully balanced 7.1.6/9.1.4 (unbalanced up to 7.3.6/9.3.4), 8K/60Hz, HDMI 2.1, HDCP 2.3, eARC, HDR10+.
- AT-600: fully balanced 7.1.6/9.1.4 (unbalanced up to 7.3.6/9.3.4), 8K/60Hz, HDMI 2.1, HDCP 2.3, eARC, HDR10+, and full Dirac Live calibration.
Across the entire series, the AT-600 stands out with six defining advances.

Six Defining Features
1.Dual acoustic calibration systems. The AT-600 pairs ToneWinner's proprietary ETQ audio measurement system with Dirac Live's patented Room Correction, Bass Control, and Active Room Treatment (ART). ToneWinner has fully settled the Dirac patent licensing fees, so AT-600 owners enjoy lifetime, no-cost access to these premium calibration tools.
2.A major DAC upgrade. Four ESS ES9081 next-generation high-performance eight-channel chips drive the audio stage. The AT-600 supports 768 kHz sampling and DSD1024, handling high-specification lossless audio with ease. Working in concert, the four ES9081 chips deliver an exceptionally high signal-to-noise ratio and finely detailed restoration across all 16 channels.
3.Sixteen RCA outputs. With Dolby Atmos and DTS:X dual decoding and full backward compatibility with all Dolby and DTS formats, the AT-600 processes 16 channels independently, extends to height channels, and adds subwoofers for a maximum 9.3.4 or 7.3.6 layout.
4.Fourteen XLR balanced outputs. Fully balanced transmission resists interference, while three independent subwoofer outputs can be expanded in parallel to drive up to six subwoofers.
5.Lossless transmission and ultra-high-definition picture. The AT-600 offers 8K video output at 8K/60Hz, pass-through for Dolby Vision, HDR10+, and HLG full-format HDR, plus eARC audio return and HDCP 2.3.
6.Human-centric design. An overlay OSD menu, dual 2.8-inch displays, and a mobile app with visualized EQ adjustment make setup and tuning intuitive.
Key Specifications
- Signal-to-noise ratio: ≥110 dB (A-weighted, 1 kHz/1 Vrms, analog input, pure mode)
- Total harmonic distortion: ≤0.003% (A-weighted, pure mode, 1 kHz/1 Vrms, analog input)
- Frequency response: 10 Hz–65 kHz (+1/−3 dB, analog input, pure mode)
- Output level: 3 Vrms ±1 dB (THD 1%, analog input, analog pure)
- Channel separation: ≥90 dB (analog input, analog pure)
- Maximum power consumption: 30 W
- Net weight: 4.4 kg
What's New
