Everything is working well so far ◎ AC adapter is not included. Vestax DJ mixer PMC 15A, working condition. Effects unit (PHASER) is not included, but I was able to use an effects unit!

Output LINE OUT, REC OUT, both output confirmed ◎ Main mic, mic 1, both input and output ◎ That's all I checked. I am not a professional, but I have been using 8 channels to the fullest with 2 turntables, 2 CDJs, MD, DVD, CS tuner, and PC. I don't have a 9th channel = 3rd turntable, but when I plugged in the cables from the two turntables I have, the sound came out properly and I was able to use it without any problems. Crossfader: Slight sound leakage depending on the position. There was no scratchy sound from the volume controls when I checked. As this is a used item, there is no warranty. Please consider this before purchasing. No refunds will be given. Please consider carefully before purchasing! There are some scratches and rust stains, but the overall condition is good. Small lever missing. The left transformer button is missing, I covered it with black rubber. The transformer itself does not function left or right in the photo. I will take a video of the input/output confirmation again before packing.
