Studio C at Heiders, SF 1971
A UREI and Switchcraft based custom built solid state design with 24 inputs and 8 busses. This photo was taken before the mods. The Pan Pots were tied into the stereo busses (4 and 5) with big lever switches at the top of the monitor section. The 3M M56 remote is at my right. Before Auratones and NS-10s, small speakers were anything you could get.

The open rack in the back contained the Mcintosh valve amplifiers; 275's for the 4 Speakers, and 240's for the cues. On the left is the side of the console is the 8-channel cue mixers which could be ganged to monitor a 16 track machine. The originall tracking monitor was very basic, routing tracks 1 and 2 to the first speaker, 3 and 4 to the second, etc. In this shot you can see a mod to the monitor section on the right edge of the console that expanded it to 16. The EQ's on the right are the wonderful UREI passive shelving units that were normaled into the lines from the tape machine. A set of 24 API 550's (not shown) were also in the rack, normalled into the 24 channels. A mistake by the techs screwed up the gain structure, so I did a lot of patching around some parts of the console, that's the mess you see here. All in all, a very simple console, and not a lot of ways to get yourself in trouble.
