This is a dbx graphic equalizer 215s. I am selling it as I no longer use it and am clearing out my equipment. I haven't checked all the functions, but it worked normally when I connected it and tested the sound. The white part of the equalizer knobs is missing in four places. There are some minor scratches from use. Please understand that this is a used item before purchasing. The manual is included, but the power cable is not. Please note that shipping may be delayed due to business trips.
