ToneWinner AT500 8K Dolby Atmos AV Processor

8K Dolby Atmos AV Processor with 16-Channel Decoding

The ToneWinner AT500 is designed for serious home theatre systems where precision, clarity and immersion matter. As an 8K-ready Dolby Atmos AV processor, it serves as the central hub of your cinema, decoding multi-channel audio formats and routing them with confidence to your amplification stage.

Built for both movies and music, it supports Dolby Atmos (with Dolby Atmos upmixing) and DTS:X, with 16 channels of decoding for layouts up to 7.3.6 or 9.3.4, and independent control of up to three subwoofers. Clean channel separation, natural soundstage placement and accurate timing make every effect land where it should.

Six HDMI 2.1 inputs and two HDMI outputs meet real-world setups, and HDMI 1 to 3 support native 8K pass-through and upscaling. HDR support covers HDR10, HDR10+, Dolby Vision, HLG and Dynamic HDR, and eARC carries Dolby Atmos back from your display.

ToneWinner's Easy Test EQ measures your room automatically (using the ETM-3 test microphone) and applies parametric EQ, while a mobile app, on-screen menu, RS232, IR and CEC control keep the processor easy to live with.

Best suited for:
High-end home theatres, custom AV installations, and systems where fidelity, scalability, and format support are essential.
