Please take a look at the photos. This is a compact, all-in-one PA system consisting of speakers and an amplifier (mixer) to adjust the sound. The amplifier (mixer) allows for the use of up to 4 wired microphones. The two high-quality 20cm speakers make it suitable for various locations and situations. It comes with a stand set, and using the stands to set up the speakers will further expand the sound. Recommended for small to medium-sized events, live performances, school festivals, sports days, lectures, demonstrations, workshops, conferences, concerts, and festivals. It has been stored indoors and used a few times for keyboard performances, but it has not been used for live performances or outdoors, so it is in relatively good condition. I have confirmed its operation with my keyboard, and it worked without any problems. One of the stands has been used for another purpose, and there are some dirt and scratches on it. This is a used item, so please understand this before purchasing.
