AV Processor / Home-Theater Preamplifier Dolby Atmos 16 Channels 9.3.4 / 7.3.6
The Tonewinner AT-300 is a 16 channel audio/video processor and preamplifier, ideal for home theater integration in 9.3.4 or 7.3.6 configurations. It supports all current audio formats such as Dolby Atmos, Dolby True HD, DTS:X and DTS Master. Similarly, the AT-300 accepts video streams up to 4K UHD 60Hz and is compatible with HDR, HDR10 and Dolby Vision technologies. It allows you to enjoy the latest and greatest formats available for the most immersive audio and visual experience possible.
Advanced video processing
The video processing section for the AT-300's HDMI inputs and outputs uses a Panasonic MN864788 controller. It supports 32bit streams, resolutions up to 4K (3840*2460px) 60Hz and is compatible with RGB/YUV 4:4:4 color spaces.
A powerful audio section
The audio part of the AT-300 relies largely on two Cirrus Logic CS42528 chips, ensuring at the same time the functions of DAC, ADC and SPDIF receiver. These ensure a quality sound reproduction thanks to a wide dynamic range and a very low level of distortion and noise.
SHARC DSP
Combined with these chips, an Analog Devices ADSP-21573 SHARC floating point DSP takes care of decoding Dolby Atmos and DTS:X audio formats to create a truly immersive and consistent sound experience with excellent channel separation.
Precise volume control
Quite rare on this type of device, the volume control is here with resistance switching. Such integration allows a precise and non-destructive adjustment of the sound level.
A breathtaking image
The Tonewinner AT-300 supports all current video technologies and formats. With 18Gbps of bandwidth and HDCP 2.2 compliant HDMI 2.1 connectivity, it easily decodes 4K UHD 60Hz video streams. It also supports HLG, HDR10 and Dolby Vision technologies, bringing an incredible level of brightness and contrast for an exceptional image quality.
Automatic audio calibration
With the ETM-2 measurement microphone (sold separately), the AT-300 is able to automatically calibrate and correct your audio system. The microphone captures the sound information emitted by your speakers and applies automatic equalization to each channel, depending on your listening position.
To go further in the equalization...
In addition to the automatic calibration, it is possible to adjust the equalization manually. Indeed, the Tonewinner AT-300 provides an 11-band parametric equalizer for the left, right and center channels and a 5-band equalizer for the surround, top and bass channels. This equalization can be done directly from the graphical interface of the device.
One memory for each group of inputs
Each group of inputs has an equalizer and independent effects. These different parameters are stored by the device and automatically selected according to the selected input.
Multiple configurations
The Tonewinner AT-300, in order to adapt to different environments, can be used in several configurations: 2.0, 2.1, 5.1, 5.1.2, 5.1.4, 7.1, 7.1.2, 7.1.4, 7.3.6, 9.3.4... So no matter what room you use it in, the AT-300 will fit right in and let you enjoy your audio and video content.
Storage of volume levels
For each channel, the AT-300 allows you to apply a volume level setting and limitations that can be saved and applied as soon as the unit is turned on.
Bluetooth
In addition to a particularly extensive connectivity, the AT-300 integrates a Bluetooth receiver. This one allows a wireless audio broadcast, from a smartphone or a tablet for example. The control of the playback is then done directly from your mobile device for a simple, fast and convenient use.
