Marantz SR-6000
A model number that turns up in the archives attached to two entirely different machines — and the paper trail only supports one of them.
Overview
This entry exists mostly as a warning about how model numbers get recycled across the audio world. The "Marantz SR-6000" as catalogued here has no supporting documentation behind it — the research file is empty, with no confirmed production years, no price, no power rating, no dimensions, and no owner reports, though period audio coverage of the era does include the SR-6000 among receivers reviewed in HiFI-Stereo (September 1979, p.75). What the period sources in the archive do describe under the SR-6000 designation is a professional mixing console from TAC, the Total Audio Concepts arm of Amek, shown at trade exhibitions in the early 1990s. That is a very different animal from a Marantz home receiver, and collectors should treat any "Marantz SR-6000" listing with suspicion until a serial plate or service document settles the question.
The TAC SR6000, as the contemporary trade press covered it, was introduced at the NSCA show and offered in 24-, 32-, or 40-channel frame sizes. Its channel strip carried 4-band semi-parametric EQ, and the desk provided eight subgroups, eight VCA/mute groups, and four stereo effects returns. The unusual feature was a split auxiliary bus system: each channel had eight aux sends, but the split aux masters let any or all of those buses be divided between the left and right halves of the console, effectively creating up to 16 separate aux buses. Recording-Engineer reported a 40-channel list price of $59,500 at launch. The same coverage identifies the SR6500 as a companion foldback console sharing only the frame with the SR6000, offering 18 discrete monitor mix outputs, eight VCA-mute groups, and a choice of 24, 32, or 40 mono inputs.
None of this is a Marantz product. The name collision is the whole story here. A hobbyist searching for a Marantz SR-6000 receiver will instead surface trade-show coverage of a British-designed live-sound desk, and the reverse is true for a studio tech hunting TAC documentation. Until a genuine Marantz document — an owner's manual, a service sheet, a catalog page — turns up naming an SR-6000 receiver, the archive treats the Marantz attribution as unverified. The TAC console is the only SR-6000 the period record actually documents.
