The JH-400 holds a unique place in console history: it was the first console ever built with an in-line configuration, integrating both the recording and tape-return paths on a single channel strip. The idea came from audio engineer and dealer Dave Harrison, who commissioned MCI to build a console capable of switching between recording and mixing workflows without the engineer having to physically reconfigure the desk. Every in-line console that followed — Neve, SSL, Harrison's own company — owes its architecture to this moment. The JH-400B refinement brought automation capability (JH-50 automation package), improved EQ, and lower distortion.
