ProFX6v3+ 6-channel Mixer with Effects and USB

This mixer came already with some problem on the frequency, at the beginning I was confused and think that the sound so bright was normal, but after now 10 months that I have it I saw big problem, all instruments that I plug on it become bright sound, and I have to close all right frequency and it still with this problem, now I can not use it for work, because in addition to the super high-pitched sound, there are also sound noises as if there was some interference, I'm going to send it for assistance because it's still under warranty, but I don't think it can be fixed, in short, I WILL NEVER BUY MAKIE PRODUCTS AGAIN, going back to YAMAHA

i recieved the old item, the box is old.. without power adaptor and no styrofoam to protect my item. very old. prepared to return and refund

الجهاز رائع فيه عيب واحد فقط ان واير الكهرباء قصير لكن كل شىء عدى ذلك ممتاز
