Sony PCM-R700
Sony's top-of-the-line non-timecode DAT deck: four heads, four direct-drive motors, and a $2,695 list price that put it squarely in the pro rack.
Overview
The PCM-R700 is a DAT recorder built for people who couldn't afford to babysit a tape. Sony positioned it as its top-of-the-line non-timecode DAT machine, and the feature list reads like a working engineer's wish list rather than a consumer deck's bullet points. The transport runs on four direct-drive motors, and the head assembly carries four heads rather than the usual two — which is what unlocks read-after-write and read-modify-write operation, the confidence-monitoring trick that lets you hear what just landed on tape while you're still recording it. For anyone who ever lost a take to a dirty head or a misaligned transport, that's not a spec-sheet flourish; it's insurance.
The list price tells you where this sat in the market. Sony's own dealer literature from the period listed the PCM-R700 at $2,695.00 manufacturer's list — a figure that puts it well above the scaled-down PCM-R500 at $1,875.00 and the budget PCM-R300 at $995.00 in the same catalog. That's the top of a three-rung ladder, and the R700 is the only one of the three that gets the four-head construction and the dual read-after-write/read-modify-write capability. The R500 shares the four-motor transport, the jog/shuttle dial, SBM, the 8-pin parallel remote port, and the same balanced XLR plus unbalanced RCA analog I/O with AES/EBU and coaxial digital connections — but not the four-head confidence monitoring. If that feature matters to how you work, the R700 is the model that has it.
Around the transport, the R700 is built for hands-on operation. There's a jog/shuttle dial for scrubbing and locating, fade-in/fade-out on both record and playback, independent left and right recording level controls, and a wireless remote. The rear panel carries an 8-pin parallel remote control port for wiring into a console or edit controller, alongside the balanced XLR and unbalanced RCA analog inputs and outputs and both AES/EBU and coaxial digital I/O. Sony also built in its Super Bit Mapping recording function, which the company credits for the deck's high signal-to-noise ratio — SBM being Sony's scheme for folding a higher-resolution A/D conversion down to standard 16-bit DAT without the usual low-level grit. The R300 in the same catalog spells out the mechanism: a 20-bit-resolution A/D converted down to 16-bit for recording to standard DAT. The R700 carries the same SBM recording function.
Period coverage places the machine in the professional and project-studio channel rather than the hi-fi shop. Studio Sound (July 1997, p.30) ran a hands-on investigation of the new PCM-R700, framing the challenge of DAT ownership as finding "a balance of functionality, reliability and cost" — which is a fair summary of what the R700 was chasing at its price. The same magazine's October 1997 issue (p.93) and Sound on Sound (October 1997, p.69; January 1998, p.101) carried the R700 in dealer listings alongside the PCM-R500, the CDP-L3 CD player, the DTC-A8 DAT recorder, and the DPS-V77 multi-effects processor, distributed in the UK through HHB Communications. That distribution picture — pro audio dealer networks, not consumer electronics chains — tells you who Sony expected to buy it.
What the R700 doesn't give you is timecode. It's explicitly a non-timecode machine, which is the whole reason it sits below Sony's timecode-capable DAT models in the professional lineup. If your workflow depends on SMPTE timecode striping for synchronization, this isn't the deck. If you're doing straight two-track mastering, location recording, or broadcast production where confidence monitoring and clean digital I/O matter more than timecode, the R700's feature set lines up almost exactly with the job. The 8-pin parallel port and the fader-start-friendly remote wiring are there for console integration, not for chasing picture.
Collectors and working studios chasing DAT today tend to care about three things on these machines: the transport's reliability, the head condition, and whether the digital I/O still handshakes with modern converters. The R700's four-motor direct-drive transport is the reassuring part of that equation — fewer belts and idlers to perish than a consumer deck. The four-head assembly is the part that needs attention, because confidence monitoring only works if all four heads are clean and aligned, and a worn head stack on a deck this age is a real service question rather than a hypothetical. Buyers should expect to verify that read-after-write actually functions before trusting a used unit, and should treat the absence of timecode as a feature decision rather than a defect. The $2,695 original list also means these were bought by professionals who used them hard — condition varies enormously, and the surviving examples that were rack-mounted and maintained tend to fare better than the ones that sat in a closet with a tape left threaded.
For what it is — a non-timecode, four-head, four-motor DAT recorder with balanced and unbalanced analog I/O, AES/EBU and coaxial digital, SBM, and console-friendly remote control — the PCM-R700 is one of the more complete DAT decks Sony built for the professional market. It's not the flagship of the whole DAT line, and it doesn't pretend to be. It's the top of the non-timecode branch, priced and specified for people who needed confidence monitoring and clean I/O without paying for timecode they'd never use. That's a narrow brief, and the R700 hits it squarely.
