I'm modifying the YABER Y60 so it can be connected to speakers. You can switch between the built-in speaker and external speakers using the switch on the back. You can enjoy movies with good sound quality by connecting speaker cables directly to the speakers without an amplifier. A screen cloth is also included as a bonus. I believe it's 100 inches, but it might be 120 inches. Rest assured, it's at least 100 inches. The screen is just a bonus, and as with the main unit, I cannot accept complaints about the screen, so please purchase only if you understand. Also, since I'm selling it at a bargain price, please refrain from purchasing if you are particular about minor details. There will be an unusual noise from the fan when it starts up, but it will settle down and stabilize after a while. I think a projector with the specification to drive speakers without an amplifier doesn't exist, so I think this is a very rare custom modification. Thank you. Compact black projector with focus adjustment function. - Color: Black - Connection terminals: HDMI, RCA, USB - Control panel: Operation buttons on top - Lens adjustment: Focus adjustment dial Thank you for viewing. I will only sell to those who can use Eco Mercari delivery.
