TONEWINNER AT-600 Audio-Video Processor / Home Theater Preamplifier

The Tonewinner AT-600 is a 8K 16-channel home theater processor designed for processing immersive configurations up to 9.3.4, relying on a dual-core DSP combined with an ESS DAC to ensure precise multichannel stream management. It integrates an HDMI 2.1 interface compatible with 8K with an independent routing matrix, complemented by varied digital and analog inputs and 16-channel outputs in RCA and 14-channel outputs in XLR, allowing flexible integration with multiple subwoofers. The whole is completed by the integration of Dirac Live with advanced bass management, automatic calibration of distances, delays and levels, as well as a per-channel parametric equalizer, allowing precise adaptation of system behavior to the room and sources.

Tonewinner AT-600: Audio architecture and multichannel processing

The AT-600 relies on an ESS ES9081 DAC chip combined with a dual-core Analog Devices DSP, allowing processing of multichannel audio streams while maintaining high-resolution conversion accuracy. It supports Dolby Atmos, Dolby TrueHD as well as all backward-compatible Dolby formats, as well as DTS:X and DTS-HD Master Audio with their associated variants.

It allows configurations ranging from 2.0 up to 9.3.4, corresponding to 9 main channels, 3 subwoofers and 4 height channels. Analog outputs are available in 16-channel RCA (up to 9.3.4) and 14-channel balanced XLR (up to 7.1.6 or 9.1.4), allowing precise adaptation of connection type and number of subwoofers depending on the installation.

Tonewinner AT-600: Control and user interface

The AT-600 integrates an interface composed of two 2.8-inch screens allowing display of operating information, complemented by an OSD display in Chinese and English for on-screen navigation. Control can be performed via mobile application or remote control, allowing access to configuration and playback functions.

Audio playback is ensured via USB and TF card with file tree management and synchronized display of lists on screen and mobile application, allowing standalone use with FLAC, APE, WAV or MP3 formats. Adjustment of the audio delay up to 1000ms allows precise synchronization of sound with the image. An integrated wireless audio receiver allows reception of audio streams from a compatible source, expanding usage possibilities without wired connection.

Tonewinner AT-600: Measured performance and structure

The AT-600 features a signal-to-noise ratio greater than or equal to 110dB and a total harmonic distortion less than or equal to 0.004%, measured in pure analog mode, allowing maintenance of a low-noise signal with controlled distortion. The frequency response extends from 10Hz to 65kHz (+1/-3dB), while the output level reaches 4Vrms and channel separation ≥90dB.

The chassis is based on a metal structure, allowing limitation of interference and ensuring stable operation within a home theater integration.
