Offered is an AudioControl Model D-10 10 Octave Equalizer with Subsonic Filter, Made in USA, unit SN F12556. Condition is used - unit is clean and fully functional. Wood sides are nice, no visible scratches, the four rubber feet on the bottom have shifted some but are still stuck to the unit. From a family member so I know the history - smoke free home, stored for a while in a closet in the house that was climate controlled. I have been using this in a system for about a year, everything works as it should - see video. I do like the bands split out between bass, midrange and treble right where you can see them...As a precaution, before using, I did clean the controls with DeoxIT Fader F5. There is no cracking when adjusting the sliders Just a note - this does not have a power on/off button so once you plug it in it is on. It would be best used with another vintage component that has a rear switched outlet or a master power conditioner that turns everything on/off at the same time. Vintage EQ from AudioControl, Made in the USA! Please view all images as this is the exact item you will receive.
