Otari MKIII-8
A half-inch eight-track with a professional pedigree for project studios. Period advertising said it came at a "non-ultimate price."
Period advertising billed the MkIII-8 as "the only truly professional 2" 8-track," built on the well-proven 5050 transport with a microprocessor-controlled transport (Studio-Sound, December 1983, p.56).
Overview
The MKIII-8 is Otari's half-inch eight-track open-reel multitrack. Period advertising described it as a "fully professional compact 8 track recorder" built to the same standard as the company's larger machines, and pitched it "at a non-ultimate price." The idea was simple. Take the facilities and build quality normally reserved for one-inch machines and put them on half-inch tape for the budget-conscious studio.
The transport is the foundation. Otari based the MKIII-8 on its well-proven 5050 transport, a deck with a long service record behind it, and the machine is microprocessor-controlled (Studio-Sound, December 1983, p.56). Period advertising described the MkIII-8 as the only truly professional 2" 8-track, built around that same 5050 transport (Studio-Sound, December 1983, p.56). Tape speeds are 15 and 7½ ips via a DC servo, direct-drive capstan. The tacho output and servo capstan are what made the MKIII-8 suitable for audio/video locking work. Otari explicitly marketed the deck for interfacing to video synchronizers for "audio sweetening," which means syncing tape to picture for post-production houses. A synchronizer interface came as standard, and an autolocator was offered as an option.
Inside, the MKIII-8 uses a single card per channel, and the electronics are externally accessible for adjustment. That helps when a machine lives in a working studio and gets recalibrated for different tape stocks. There's a built-in 1kHz/10kHz test oscillator, an LED tape timer, and a peak indicator. Otari's own literature says the audio control section carries the same functions as the 2-inch MTR90 series, and that all audio and transport functions are repeated on the optional full-function remote.
Pricing in the period press put the recorder in an Otari/ITAM "ultimate compact 8 track studio" bundle. The MKIII-8 was paired with the new Itam 12-4-8 professional multitrack mixer, which could continuously monitor all eight tracks while recording and normaled the eight tape returns into the line inputs of eight of its twelve channels. One 1983 listing quoted the complete system at £6,350, subject to stock. On the used market the numbers fell fast: a 1988 dealer listing had an MKIII-8 at $3,700, and a 1989 list at $4,700.
Otari's own advertising billed the MKIII-8 as "the only truly professional ½-inch 8-track," and the company leaned hard on the 5050-transport heritage and a synchronizer interface as standard. That's marketing copy, not an independent verdict.
