Designed around a 7-channel amplification architecture and a wide preamplification section (configuration up to 5.1.2), it incorporates amplification capable of delivering up to 120W into 8 ohms, based on a robust power supply and Hi-Fi circuits ensuring stability and dynamics. Compatible with 3D Dolby Atmos, Dolby TrueHD, DTS:X and DTS-HD audio formats, it also supports recent video standards such as 4K, HDR10, Dolby Vision, HLG and 3D, with full HDMI signal management (HDMI 2.1, ARC, CEC, HDCP2.2).
Designed as a true audiovisual hub, the AT-2700 offers numerous functions: audio playback via USB, TF card, Bluetooth, mobile app control, automatic calibration with room EQ, as well as advanced DSP audio processing. Its complete connectivity includes 4 HDMI inputs and 2 HDMI outputs, optical, coaxial and analog inputs, as well as dual subwoofer outputs. It integrates equally well into a home theater system or an advanced Hi-Fi or multimedia installation.
The Tonewinner AT-2700 relies on internal amplification capable of directly powering a complete immersive installation. With 7 amplified channels and an output power of 120W RMS into 8 ohms, it offers substantial power reserves to drive demanding speakers, even in large rooms.
This power is combined with a carefully engineered design featuring controlled distortion (≤0.05%) and a high signal-to-noise ratio (≈90dB), ensuring clear, dynamic and controlled sound reproduction for both cinema use and music listening.

The AT-2700 supports the most advanced immersive audio formats, including Dolby Atmos and DTS:X, allowing the creation of an enveloping three-dimensional soundstage. It can handle complete configurations up to 5.1.2, with precise positioning of effects in space.
It also remains compatible with previous formats (Dolby TrueHD, DTS-HD, etc.), ensuring full compatibility with current content, whether Blu-ray, streaming or local files.


A true central hub of a home theater system, the AT-2700 ensures complete management of high-definition video streams. It supports 4K, HDR10, Dolby Vision, HLG and 3D formats, with high bandwidth allowing passthrough of 4K/60Hz RGB 4:4:4 signals.
Thanks to its HDMI 2.1 inputs/outputs, it allows easy connection of all modern sources (Blu-ray player, console, TV box), while ensuring optimal transmission to a television or projector.
The Tonewinner AT-2700 integrates complete digital signal processing with DSP, allowing sound reproduction to be optimized according to the listening environment. It offers:
These functions make it possible to achieve coherent and balanced sound reproduction, even in complex rooms.

The Tonewinner AT-2700 relies on a dedicated mobile application allowing easy control of the device and access to its multimedia functions. This app provides remote control of audio parameters, sources, volume and certain advanced settings, with an interface adapted according to the type of device connected via Bluetooth.
On the streaming side, the AT-2700 offers great flexibility of use. Thanks to its built-in Bluetooth receiver, it allows wireless music streaming from a smartphone, tablet or computer, with a stable and fast connection. It also supports direct playback of audio files stored on a USB drive or micro SD card, including high-resolution formats.
