Otari MTR-9011
A twenty-four-track workhorse that studios bought by the pair and rented out by the hour.
Overview
The MTR-9011 turns up in the trade press in odd places. It's not in the lead photo of a brochure. It's in the fine print of a studio's gear list, wedged between a Sound Workshop console and a Lexicon 224XL. Working rooms bought this multitrack. It showed up in the equipment inventory of a Northern California studio alongside a Sound Workshop console and a rack of UREI limiters. Otari built it as a 24-track analogue multitrack, and the trade-show listings of the period put it at the center of the company's professional line. The Studio Sound (March 1987) show roundup placed the MTR-9011 24-track right between the MX-80 and the BTR-5 broadcast machine in Otari's stand.
Collectors care less about any single headline number than about how the machine was deployed. Studios didn't buy one - they bought two. A European facility listing in Studio Sound (October 1993) advertises a pair of MTR-9011 24-tracks with locator and remote. That's the standard configuration for a room that needed to bounce between machines or keep a backup aligned and ready. Engineers trusted the thing enough to build a workflow around two of them.
By the late 1980s a new MTR-9011 was listed at $26,500 and $29,900 in a Mix (September 1989, p.192) dealer column. Those two figures likely reflect configuration differences, since the machine was sold in variants. Three years later the used market had softened to roughly $25,500 for a 24-track example. That's a shallow depreciation curve for a piece of analogue iron. Buyers kept paying near-new money for used ones because the alternative, a digital multitrack, was still a gamble in that era.
Mix (December 1989) carried a dealer listing for an MTR-9011 at $30,000 and, in the same column, a 16-track MTR-9011 variant. That's worth pausing on: the 9011 was offered in both 24-track and 16-track form, and the model number alone doesn't tell you which one you're looking at. Anyone shopping a used example today should confirm the track count before anything else, because the two configurations shared a name and a chassis family. A 1995 Studio Sound used-gear column still had an MTR-9011 sitting in stock alongside the bigger MTR90 MkII and the MX80, which is a fair snapshot of where the model landed in the hierarchy — below the flagship MTR90, but still worth listing by name a decade after introduction.
The detail that comes up most often in period documentation is the modular construction. Otari's own dealer copy from Studio Sound (January 1984, p.7) made a point of the "totally modular design," arguing that servicing and alignment would be simple enough that a studio could evaluate the machine on its own bench. That's marketing, but it's aimed at the engineer who has to keep a 24-track aligned at 2 a.m. before a session. Modular channel electronics and a transport built for routine maintenance are what kept these machines in service while lesser decks got parted out.
The surviving documentation is thin on hard figures for the sound and the numbers - the wow and flutter, the frequency response, the head configuration - and this archive won't invent them. What the record does show is a machine that professional rooms specified by name, priced like a serious investment, and kept in pairs.
