“1972 was the year when we started building our first “production” console series, JH-400’s. This design evolved from some of Dave Harrison’s ideas. I had known Dave from the days when he had worked at Criteria, and he also played in Wayne Cochran’s band in Miami. Then he did studio maintenance for Sid Nathan at King Records, and worked his way up to become studio engineer and manager. Sid also owned part of a recording operation in Nashville and transferred Dave there. When Sid died, the studio was wound down and went out of business, leaving Dave to start his own company, The Studio Supply Company.

“At this time our dealer in Nashville was Dan Flickinger, but we dissolved our relationship after his accident. I then made Harrison’s Studio Supply Company the Nashville dealer for MCI tape machines and he did quite well at it. Shortly thereafter Dave approached me about designing a new kind of console. He had some ideas, and I told him that if he design it, MCI would build it. Dave came down to Florida and started drawing and laying tape, and we built a run of six consoles. These boards were quite unusual for their time – the track assigns were in-line with the monitor and main channel fader. The console was similar to Flickinger’s earlier concept except that his boards had the track assignments off to the right of the channel area. After the first run of six, I decided to do some additional work on the design – changing some of the metal work and adding other circuitry. We also incorporated the Harris 911 IC op-amps which lowered costs and made the product more manufacturable. All in all, I think we built about two hundred of those ‘Series 400’ consoles between 1972 and 1977” Jeep Harned from this interview
