Hello: I have a pair of Ev interface D III speakers but lost the equalizer in a flood. I bought an Interface A equalizer with hope of converting to an interface D spec. Do you know how this is done? Is there source of information to do this? I would be grateful for any help you can afford. Thank you very much. Ed DeLucca. Edelucca337@comcast.net. I am a member of Audiokarma.
