This is a 7.1ch AV amplifier compatible with 4K, Dolby Atmos, and DTS-X. It supports Spotify, Bluetooth, etc., allowing for easy high-quality music playback! I was using it until recently, so I believe it is in good working order. The included accessories are the remote control, YPAO microphone, power cable, and instruction manual, as shown in the photos. I will also include the Belden speaker cable shown in photo 6. It is a very clean product, but it is a used item, so please understand this before purchasing. * There may be some signs of use associated with used items, but it is in generally good condition. * There may be scratches or scuffs that are difficult to see in the photos. * Please refrain from purchasing if you are sensitive to imperfections or are looking for a perfect item. * Everything in the photos is included. #YAMAHAAVamplifier #HomeTheater #DolbyAtmos #DTS-X #YAMAHA
