MCI JH-538
A big automated console that turns up in studio classifieds more often than in spec sheets. That says something about who owned one.
Overview
The JH-538 is an MCI console that serious rooms bought, worked hard, and then sold off through the classified pages a few years later. The paper trail is thin and mostly secondhand, but what survives is consistent. This was a large-format automated desk, and it sat at the center of working facilities, not in collector display cases.
The clearest evidence of what the JH-538 was built to do comes from the studios that ran it. A 1985 equipment listing for Howard Schwartz Recording Studios in DB-Magazine (July 1985, p.41) gives the console complement as MCI JH-538 and JH-556 desks, fully automated with Spectra-View and twelve echo returns. So the JH-538 shows up next to the JH-556 in a room running a matched MCI front end, not one odd console. The same listing names the monitoring chain (UREI 813s, Auratones, JBL 4311s among others) and a broad amplifier selection. That puts the JH-538 in a conventional large-studio signal path, not a specialty or broadcast-only one.
The classified market tells a similar story about scale. A 1980 Mix (May 1980) equipment-for-sale notice offers an "MCI JH 538-38, 38x38, 60 options, plasma LED, 46 function JH-50 1979 less than 100 hrs". That description only makes sense for a full-frame automated desk with a big option load. The "38x38" framing and the option count suggest a console configured well beyond a basic tracking frame, and the JH-50 with 46 functions points to automation hardware bundled with the desk, not added later. The same notice lists the JH-538 with a pile of other MCI gear (a JH-114 transport, a JH-416 24x24, a JH-16-24 pair). That is how these consoles moved in the early '80s, as part of a studio's wholesale turnover.
The JH-538 keeps showing up in for-sale columns, and that is itself a fact about the model. In Recording-Engineer (April 1980, p.180) and again in the August 1980 issue (p.119), the same Paramount Sound classified ad runs. It offers an "MCI JH-538 Automated Console" together with MCI 2-, 4-, 8-, 16-, and 24-track machines and JH-45 synchronizers, all described as having less than 150 hours of use. A console a facility is trying to move with under 150 hours on it was bought, installed, and then either underused or displaced by a change in plans. It was not ridden into the ground. Collectors note that the "automated" descriptor is attached to the JH-538 in essentially every period mention. It is the most reliable thing the record supports about the model.
The surviving documentation does not give a clean spec sheet. There is no published input count, no bus architecture, no EQ topology, and no module complement that can be stated with confidence here. The "38x38" figure from the 1980 classified describes one specific console's configuration. It is not a factory rating for the model. Reportedly it was a 38-input, 38-output arrangement on that particular desk, with a 60-option load and a JH-50 automation package. Nothing in the record establishes whether every JH-538 left the factory similarly equipped. Owners report the desks were configurable and that option counts varied widely between installations, which fits the classified language but cannot be pinned to a standard build.
Automation runs through all of it. The JH-50 reference in the 1980 Mix listing and the "fully automated with Spectra-View" description in the 1985 DB-Magazine studio profile both point to the JH-538 being sold and used as an automated console first and a summing frame second. For anyone considering one today, the automation package is the part that defines the desk. It is also the part most likely to have been serviced, modified, or abandoned over the decades. The Howard Schwartz listing even notes the studio was replacing and upgrading older equipment at the time of writing, which is the usual fate of a large automated MCI desk: displaced by a newer console and sold on.
On collectibility, the JH-538 is a working console, not a trophy. The period record shows them changing hands as part of studio liquidations, often bundled with tape machines and synchronizers, and the descriptions stress condition and low hours rather than provenance. There is no documented collector market, no established price guide, and no restoration literature specific to the model in the sources here. Anyone chasing one should expect to evaluate the automation and the module complement on the specific desk in front of them, because model-level documentation does not exist in the material available.
