The preamp stage has been carefully modeled after the preamps in the famous Wally Heider Recording Studio 4 console custom built by Frank DeMedio circa 1972. The original pre's were stock 312 cards modified by DeMedio. Frank removed the AP2622 input transformer and replaced it with a custom wound Ed Reichenbach RE-0887. The RE-0887 has a very special tonal quality with some of the most buttery smooth mids you will ever encounter! CineMag owns Reichenbach Engineering and continues to manufacture all of the original designs to original specifications. CineMag has done a fantastic job with the current RE-0887's, working straight off of Ed Reichenbach's original notes and winding data from 1972. For those who don't know, Ed Reichenbach's son Tom went on to form CineMag in 1979 after working with his father for some 25 plus years.

In remaining true to the Heider circuit, all AC coupling capacitors have been removed from the audio path. I don't think coupling caps are evil, they are just not needed in this particular circuit. This fader booster stage has 12dB of gain 'in hand', exactly like a real console. This allows for many different gain combinations.
