Korg 880 A/D

An eight-channel converter built for Korg's modular SoundLink DRS system. It's useless without the rest of it.

Overview

The 880 A/D is not a standalone product in any meaningful sense. It is one piece of Korg's SoundLink DRS - Digital Recording Systems - a modular architecture the company pitched as an integrated digital recording environment rather than a single box. Studio Sound (April 1996) reported that SoundLink DRS comprised the 168RC recording console, the DRS 1212 PCI multichannel audio I/O, and the 880 A/D and 880 D/A converters. The converters were described as 8-channel units available to expand the 168 and 1212 via ADAT optical cables. That is the 880 A/D's whole job. It takes eight channels of analog and hands them to the rest of the chain over ADAT optical.

The rest of the system is worth understanding before anyone buys one. The 168RC was a 16:8:2 console with 18-bit conversion, two ADAT connections, and eight analog inputs, per Studio Sound (April 1996). The 1212 I/O card offered 12 ins and 12 outs - two analog I/Os, an S/PDIF I/O, and eight channels of ADAT optical I/O - and shipped with Deck II software. Korg's own advertising from 1996 made the pitch plainly: with the 1212 I/O and Deck II, full-function multichannel computer recording became affordable, and because the card conformed to PCI, the investment would "last longer than just a few months." The 880 A/D sits at the analog edge of that chain, converting signals that the 168RC or 1212 could then route and record.

Anyone chasing an 880 A/D today should know what they are getting. The unit converts, per the system documentation, but it does not work alone. The ADAT optical link is the entire output path, and without a 168RC, a 1212 I/O, or another ADAT-equipped device downstream, the converter has nothing to talk to. EQ (November 1996, p.76) described the system as deliberately modular, noting that a user could buy the components needed now and plan for expansion later. That was a sensible sales strategy in 1996. Three decades on, it's a compatibility headache for anyone buying a single piece.

The surviving documentation doesn't say what the 880 A/D sounds like, what converters it used, or how its clock behaved. It doesn't say whether it held up against competing converter boxes of the mid-nineties either. The period coverage treats it as a system component rather than a review subject, and no independent bench test of the 880 A/D alone appears in the available record. Owners report on the unit's practical reality rather than its measured performance, and the practical reality is that it is a brick without its siblings.

Korg's SoundLink DRS advertising leaned hard on the promise of a fully digital path. The 1212 I/O campaign copy promised that the devices would "interface with your existing analog equipment and form the basis for a completely digital system that will give you sound and creative control that simply isn't possible in the analog world." The 880 A/D was the analog-to-digital gateway in that story. For a buyer now, the gateway only opens onto a specific, discontinued digital ecosystem.
