Aphex 109

Audio Proz Inv #: 40249

Parametric EQ w/tube essence, 2ch each with Gain, EQ, Freq, Bandwidth, Stereo or mono setup - Like New condition with box, packing, manual, etc. Decent design but the typical trouble which occurs is the controls age out badly, etc. They get loose and scratchy. I can fix this issue. I only sell low use things for this reason. Oddly not a lot of tube color in this design, the Aphex mic pre had more. I often refurbish old certain ADC, Sony, Radio Shack EQ, because of "cap and coil" design does effect vintage thickness (also because of single ended class A transistor design is like a tube character thing). If you need the best tube EQ, quality of controls, headroom etc., it's the ART Pro Channel (I own a few). 90db noise floor and it is really capable of wide or super sharp filters. It uses full size parts and pieces like old Yamaha and Tascam products. I can do a mod on this which allows honest variable tube harmonic level and phase. You can truly dial it in. See our ART Pro MPA Mic Preamp (has similar features).

ART Dual Tube EQ

Audio Proz Inv #: 40817

2 channel parametric tube EQ xlr 1/4 inch out. New item. I bought as many as I could get, not made now. Truly one of the best tube eq’s ever done. People don’t appreciate ART. People buy names, seldom truly excellent engineered products. I kid you not the new ART preamp and processor are better than the fanciest names. Compare schematics, open the units, listen honestly…
