This is a BEHRINGER EUROPORT EPS500MP3 powered mixer. [Shipping] The items in the first image are all that will be sent. It will be carefully packed with air cushions, etc., and shipped. [Operation] There is a slight problem with the connection between the mixer and the speakers. Although very rare, the R channel sometimes doesn't output, but it's not consistent, suggesting a contact issue. There are no symptoms like the output stopping midway after starting. Please consider this as a junk item. Other than the above, it works without any problems. We plan to ship via Yu-Yu Mercari. Please consider. (No returns or cancellations)
