MCI JH-618
A broadcast-configured console from the Sony-era MCI years, sold as the centerpiece of turnkey studio packages rather than as a bare board.
Overview
The JH-618 is one of those MCI products that surfaces less often in collector conversations than the tape machines, yet it sat at the heart of plenty of working rooms. MCI built it in at least two configurations, and the distinction matters: a broadcast version with 10 mic inputs and five stereo line inputs, and a larger production version that shows up in the field with 18 input channels. MCI's own advertising, placed in the trade press during the Sony Broadcast era, positioned the JH-618 as the studio-side counterpart to the compact JH-800 — the JH-800 for the road, the JH-618 for creative production back at the facility. Mix (1984, p.42) carried the same "Inside. Outside. Or both." campaign, which framed the pair as a deliberate two-console strategy rather than one board trying to do everything.
What makes the JH-618 interesting to anyone tracing MCI's arc is that it belongs to the period after Sony Broadcast absorbed the brand. The advertising of the early 1980s carries Sony Broadcast's name alongside MCI's, complete with regional sales offices in New York, Chicago, Los Angeles, Atlanta, and Dallas. Collectors note that this corporate overlap is part of the story — the JH-618 is a Sony-era MCI console, and the marketing reflects it plainly. Recording Engineer (December 1983, p.10) carried the same JH-618/JH-800 pairing, reinforcing that this was a coordinated product push across multiple trade titles rather than a one-off placement.
The 18-input production variant turns up in real facilities. One documented installation describes a station production room built around a JH-618 with 18 inputs, stereo and mono mix outputs, and a built-in patch bay — the kind of self-contained architecture that made these boards attractive to broadcast production departments that needed to move fast without patching out to a separate jack field. That same room ran MCI JH-110B tape machines alongside the console, which is the typical MCI ecosystem: the board and the decks sold and lived together.
Then there's the package angle, which is arguably the most revealing thing about how the JH-618 actually reached customers. Studio Sound (October 1980, p.55) documented an MCI bundle built around the JH-618 18-input console — listed with 18 + 2 + 6 outputs — paired with a JH-110A-8 eight-track one-inch machine and a JH-110B-2-VP stereo deck, all for under £22,000. The pitch was explicitly aimed at smaller studios that assumed MCI was beyond their budget. That framing says a lot: the JH-618 was the entry point into MCI ownership, the console that made the rest of the ecosystem reachable.
A separate trade-show report describes an MCI studio package priced at $46,000 that included a JH-618 console with an HC, JH-110B-2 reel-to-reel decks, and studio cabinetry, set up to accept an eight-track ATR, two microphones, and cart decks, with an Autolocator III for cue dubbing. Whether the "HC" denotes a specific option or configuration isn't clear from the surviving documentation, and owners looking to match a used board against original spec should treat that designation with some caution. What the package pricing does confirm is that MCI sold the JH-618 as part of a system, not as an isolated purchase — the console came with furniture, decks, and the expectation that you were buying into a workflow.
For anyone considering one today, the practical reality is that the JH-618 is a broadcast and production console, and it should be evaluated as such. It's not a recording-studio flagship in the way some of MCI's larger frames were; it's a working tool built for facilities that needed clean routing, flexible input counts, and the kind of built-in patch architecture that kept a production room running. Original pricing exists in at least two currencies and two package configurations, so any figure quoted for a bare console should be treated as approximate at best.
The honest caveat is that documentation on the JH-618 is thin compared to MCI's tape machines. The surviving primary material is largely advertising and trade-show coverage, which tells you how MCI positioned the board but not how it aged in service. Collectors report that MCI consoles of this era reward careful inspection of the input modules and patch bay, but specific known failure points for the JH-618 aren't documented in the sources available here, and it would be irresponsible to invent them. What can be said with confidence is that the JH-618 was a real, shipped, working product — not a prototype or a catalog ghost — and that it anchored production rooms in both the UK and the US.
