Ресиверы — ToneWinner AT-2180

The AT-2180 is a home theatre receiver with seven power amplifier channels, produced by the Chinese company Guangzhou Tonewinner Electronics. Its processor handles Dolby Atmos together with DTS:X, carries a multi-channel karaoke section and offers a wide selection of inputs and outputs, with app control alongside a remote and an English on-screen menu.

Key specs that matter

Tonewinner rates the amplifier at 130 W RMS per channel into 8 ohm at 1 percent THD and 210 W RMS into 4 ohm at 3 percent THD, per channel at 1 kHz. Nominal impedance is 8 ohm, with loads from 4 to 8 ohm accepted. Distortion is below 0.05 percent, the response covers 10 Hz to 20 kHz within 3 dB, gain is at least 40 dB and the analog direct input level is 1 V RMS. The unit weighs 12.4 kg net, measures 430 x 411 x 160 mm and runs on 220 V at 50 Hz. A 450 W toroidal transformer supplies the output stages.

Engineering and use context

Decoding extends to 7.3.4, so 14 line-level channels are available and the receiver can work as a pre-amplifier decoder with dedicated power amplifiers and three subwoofers. Supported speaker layouts are 2.0, 2.1, 5.1, 7.1, 5.1.2, 5.1.4, 7.1.2 and 7.3.4. Object decoding and sound field processing run on an Analog Devices ADSP-21573 fourth-generation SHARC floating-point DSP, paired with a Cirrus Logic CS42528 codec that handles tone and speaker response adjustment. Video goes through a Panasonic MN864788 chip supporting 3840 x 2160 at 60 Hz, RGB and YUV with full 4-4-4 sampling and an overlay menu, and HDR compatibility covers HLG, HDR10 and Dolby Vision. Connections include four HDMI inputs and two outputs with ARC, optical and coaxial digital inputs, USB, TF card and PC audio, wireless lossless transmission, a 5 V trigger, IR input and RS232. USB drives and TF cards up to 128 GB play APE, FLAC, WAV, MP3 and WMA. Karaoke functions include a multi-tap DSP reverb, preset effects and a nine-level feedback suppression circuit. The remote has one-touch keys for video and karaoke switching, factory reset and device lock.

Pairing

The receiver fits a set of 8 ohm surround speakers with one to three powered subwoofers. Its trigger output and RS232 port also make it practical in an installed system where a projector screen or external amplifier needs switching together with the receiver.

Alternatives

The Tonewinner AT-2300PRO is the step up, with 230 W into 8 ohm on the front three channels and six HDMI inputs.
