Thank you for viewing. This is a YAMAHA 3.1ch home theater package, the "YHT-S400". My movie-enthusiast younger brother purchased it new and used it for a while, after which it was stored for a long time. I am selling it to organize things. The main unit and speakers are in good condition, with no major scratches or stains. According to my brother, it was fully functional when stored. I also checked the operation, and it seems to be working normally as far as I can see. There is no original box, but the main unit, speakers, accessories, and instruction manual are included. Please check the photos. Also, there are no pets or smoking in my brother's house. If you want to enjoy movies with good sound but find setting up 5.1ch or 6.1ch systems troublesome, how about this? Please note that this item has been stored at home for a long time without use, and is a used item that has aged over time. Therefore, please refrain from purchasing if you are looking for a perfect product or are overly concerned about condition. Shipping will be done by wrapping it in cushioning material and placing it in a recycled cardboard box. 【Overview】 ・Unique slim body for easy installation in front of the TV ・Newly developed center unit that fits compactly in a TV rack ・Clear dialogue. 3.1ch system with center speaker ・Enjoy immersive virtual 7.1ch playback with the proprietary "AIR SURROUND XTREME" technology. ・Equipped with 3 HDMI input terminals.
