Sony PCM-3348HR
A 24-bit, 48-track DASH recorder that showed up on Peter Gabriel's Up and in every rental house that could get one.
Overview
The PCM-3348HR is the high-resolution member of Sony's DASH multitrack family. It's a 48-track digital reel-to-reel built around 24-bit conversion. Sony pitched it as the heart of a complete 24-bit production system alongside the OXF-R3 console and the PCM-9000 master disc recorder. Sony's own system literature calls the package "a production platform that offers dramatically increased dynamic range," and the 3348HR is the recorder at the center of that claim. It's a studio machine through and through: a DASH-format recorder built to sit in a machine room, chase word clock, and take orders from a console.
The difference between the HR and the standard PCM-3348 is bit depth. The OXF-R3 console's multitrack busses can be dithered to 16, 20, or 24 bits "depending on the resolution of the recorder," per Sony's documentation. The HR is the machine you'd pair with the 24-bit setting. It's the 24-bit option in a line that otherwise topped out lower.
The record is thin on hard numbers. No frequency response, no THD figure, no weight, no original price survives in the documentation the Archive has been able to assemble. What does survive is a paper trail of who used it and how.
In the Studio
The most detailed account of the 3348HR in action comes from the sessions for Peter Gabriel's Up. Engineer Ben Findlay, who worked the early Real World sessions, told EQ (December 2001, p.87) that the group recordings were captured on a Sony PCM-3348HR — the magazine describes it plainly as "a 24-bit, 48 track digital recorder" — while running simultaneously to analog: Quantegy 456 at 15 ips with Dolby SR. That parallel digital/analog capture is the kind of workflow the HR was built for, and it's a useful window into how seriously engineers treated the format in the late '90s. The digital machine wasn't replacing the tape; it was running alongside it.
The 3348HR also turns up in the rack of Bob Clearmountain, who described his vocal chain for Jonatha Brooke's sessions to EQ (December 2001, p.87): a CAD Equitek E-300 or one side of an AKG C24 into an Avalon M5 preamp, patched to an SSL, then through an Apogee AD8000SE converter whose digital output fed his Sony PCM-3348HR multitrack. That's a 24-bit machine being fed by a high-end outboard converter — the HR as the final digital destination in a signal path that had already been carefully curated upstream.
Sony's own advertising in the period press positioned the 3348HR as part of the OXF-R3 ecosystem. Mix (November 1997, p.9) ran the pitch - "closer to the sound than ever before" - and framed the 3348HR with DASH PLUS as the multitrack half of a 24-bit recording system that also included the PCM-9000 master disc recorder. The same ad copy appeared again in Mix (October 1998, p.63) and Mix (June 1998, p.115), so Sony was pushing the system hard through the late '90s. Marketing copy is not a verdict, but it does establish the intended pairing: the HR was sold as the recorder you bought when you'd already committed to the Oxford console.
Interfacing and the DASH Ecosystem
The 3348HR depends on its connections, and Sony built the ecosystem around it on purpose. The OXF-R3 supports "a powerful interface to Sony DASH/DASH PLUS machines, including the PCM-3348 and PCM-3348HR 48-track recorders," and can be referenced to an external word clock supplied directly from a DASH machine. It stays locked even if the reference is varispeeded.
Sony also built MADI into the story. A forthcoming MADI card for the DMX-R100 mixer was announced to support 48 input and 48 output channels, "providing an ideal method of directly interfacing the console with MADI-capable recorders such as the Sony PCM-3348HR DASH recorder," per the period documentation. The card could also cascade dual mixers. In practice, that meant the 3348HR could be tied to a console over a single thin cable rather than a wall of AES runs.
Who Was Using It
The 3348HR's client list covers a lot of late-'90s high-end production. Dreamhire, one of the largest pro audio rental houses, bought a second PCM-3348HR to base in Nashville. VP/GM Chris Dunn told the period press the unit was "a popular request" and that no rental unit was available in the area at the time. Dreamhire's New York unit, he said, was "always busy - mostly for music recording projects, but also for occasional post-production jobs," and had a high-profile repeat customer specifically because of "its 24-bit high-resolution recording capability." Dreamhire's client roster at the time included David Bowie, Bjork, Christina Aguilera, Electric Lady Studios, Virgin Records, ABC TV, and Coca-Cola.
That rental-house demand is the most honest collectibility signal in the record. A machine that a major rental operation buys twice, and that stays booked, is a machine that was doing real work. The 3348HR wasn't a curiosity — it was infrastructure.
The 24-Bit Question
The standard PCM-3348 and the HR share the same 48-track DASH format and the same console integration. The HR's distinction is the 24-bit resolution, which is the reason Dreamhire's repeat customer kept coming back. In a market where 16-bit was still the working standard for a lot of digital multitrack, 24-bit capture was the differentiator that justified the HR badge and the premium that came with it.
The documentation doesn't give a price, a production run, or a service history, and the Archive won't invent one. What it does give is a machine that sat at the center of a deliberate Sony system - console, recorder, master disc - and that shows up in the credits of records people still argue about.
