Sony - HT-A5000 5.1.2ch Dolby Atmos Soundbar, Chromecast built-in, AirPlay2, Bluetooth - Black - Open Box - Fair

Hi MeowWoof, Thanks for your inquiry. The HTA5000 supports HDMI 2.1 specifications with the exception of VRR and ALLM. It can pass through visual and audio content up to 4K120p / 8K. There are 2 specific features (Variable Refresh Rate and Auto-Low Latency Mode) that comes with HDMI 2.1. currently not available on Sony soundbars. You can't go wrong with the HT-A5000 soundbar. The HT-A5000 has 5.1.2 channels and X-Balanced speaker units minimize distortion while the up-firing speakers and beam tweeters fill the room to give an ultra-immersive listening experience. Built-in subwoofers provide an additional boost to low end frequencies. Vertical Surround Engine and S-Force Pro Front Surround creates immersive sound from all around, while Dolby Atmos® and DTS:X® lend a more realistic, multi-dimensional sound to your content. If you want to expand your audio system, please take a look at our optional subwoofer and rears accessories (SA-SW5,SA-SW3,SA-RS3S). Regards, -Ralph
