ADAT / Lightpipe Conversion Timeline — Mac OS 9 Use, Standalone Mode & Converter ICs — 1995–2026

Scope · Native ADAT-capable converters, interfaces, mixers and recorders usable as analog I/O for a Mac OS 9 rig through an OS9-compatible ADAT host, plus a separate format-bridge section for standalone converters whose native digital I/O can be translated to/from ADAT without another A/D or D/A stage. OS 9 host means the listed unit itself has direct Classic Mac OS computer/driver support; — does not mean the unit cannot be used with an OS9 ADAT host.

Jump · Format bridges · Bridged pre-ADAT converters · 1995–1999 · 2000–2004 · 2005–2009 · 2010–2014 · 2015–2019 · 2020–2026

Format-converter bridges — expanding the scope beyond native ADAT

These boxes do not add another analog conversion stage. They translate digital formats, so an otherwise non-ADAT standalone A/D or D/A converter can still be used through an OS9-compatible ADAT host. Native ADAT and bridged ADAT remain distinct: future bridged rows should say via AI-1, via FC-8, etc. rather than being presented as native Lightpipe products.

Eligibility rule · add a non-ADAT converter only when (1) standalone A/D or D/A operation is documented, (2) its digital I/O matches a documented bridge path below, and (3) channel count / sample rate / clocking for that path are known. The narrowest device in the chain sets the limit. A format bridge does not make a host-dependent computer interface standalone.

Year	Manufacturer	Model	Digital bridge	Channels	What this opens
1993	Alesis	AI-1	ADAT ↔ AES/EBU / S/PDIF	2 at a time	Stereo AES/EBU or S/PDIF A/D and D/A converters; selectable ADAT pair 1/2, 3/4, 5/6 or 7/8; real-time 44.1↔48 kHz SRC
1993	TASCAM	IF-88SD	TDIF-1 ↔ SDIF-2	8	Chain with FC-8 or IF-TAD = ADAT ↔ TDIF-1 ↔ SDIF-2; opens early SDIF-2 converters / DASH-era digital equipment
1994	TASCAM	IF-88AE	TDIF-1 ↔ AES/EBU; S/PDIF pair	8 AES / 2 S/PDIF	Chain with FC-8 or IF-TAD = full 8-channel ADAT ↔ TDIF-1 ↔ AES/EBU path
1996	Apogee	FC-8	ADAT ↔ TDIF-1	8	Full 8-channel access to TDIF converters, recorders and mixers; bidirectional; word-clock output for TDIF-side synchronization
1998	TASCAM	IF-TAD	ADAT ↔ TDIF-1	8	Full 8-channel TDIF bridge; can replace FC-8 in the AES and SDIF-2 bridge chains above
1999	RME	ADI-8 PRO	ADAT ↔ TDIF-1 + 8ch analog conversion	8	Already in the native timeline as an A/D-D/A converter, but also acts as a standalone 24-bit ADAT/TDIF format converter / distributor
1999	Lucid	ADA8824 (ADAT)	ADAT ↔ AES/EBU + 8ch analog conversion	8	Already in the native timeline; manual explicitly supports digital I/O ↔ ADAT optical operation, so it can also bridge external AES equipment
2001	RME	ADI-8 DD	AES/EBU ↔ ADAT ↔ TDIF-1	8	Universal multichannel bridge; 24-bit; ADAT/TDIF/AES routing and splitting; extends bridged AES and TDIF access without an analog stage

Bridge chains · AES/EBU stereo / S/PDIF ↔ AI-1 ↔ ADAT · TDIF-1 ↔ FC-8 / IF-TAD ↔ ADAT · AES/EBU 8ch ↔ IF-88AE ↔ TDIF-1 ↔ FC-8 / IF-TAD ↔ ADAT · SDIF-2 8ch ↔ IF-88SD ↔ TDIF-1 ↔ FC-8 / IF-TAD ↔ ADAT

Bridged converters — pre-ADAT era

These are not native ADAT products. They qualify because their standalone digital I/O can reach an OS9-compatible ADAT host through one of the format-converter paths above. The ADAT path column shows the required bridge explicitly; the narrowest stage in that chain sets channel count and sample-rate limits.

Year	Manufacturer	Model	Conversion	Native digital I/O	ADAT path	Converter / notes
1989	dCS	900	AD	AES/EBU · SDIF-2	AES/EBU → AI-1 → ADAT or SDIF-2 → IF-88SD → FC-8 / IF-TAD → ADAT	Standalone high-end A/D; bridged, not native ADAT
1991	Apogee	DA-1000E	DA	AES/EBU · S/PDIF	ADAT → AI-1 → AES/EBU / S/PDIF	Standalone D/A; AI-1 path is stereo / 2-channel at a time
1993	dCS	950	DA	AES/EBU · S/PDIF · SDIF-2	ADAT → AI-1 → AES/EBU / S/PDIF or ADAT → FC-8 / IF-TAD → IF-88SD → SDIF-2	Standalone high-end D/A; bridged, not native ADAT

Research rule · this section can expand backward beyond 1995 whenever a standalone converter has a documented AES/EBU, S/PDIF, TDIF-1 or SDIF-2 path that can be translated to ADAT without another analog conversion stage. Keep these entries separate from the native-ADAT chronology below.

8-channel Analog ↔ ADAT-capable processors / mixers

Struck-through = does not qualify: fewer than 8 analog I/O channels and/or no ADAT.

Alesis

• DEQ830 — 8 analog I/O ↔ 8-ch ADAT
• DEQ230D — 2 ch; S/PDIF only, no ADAT
• QuadraVerb 2 — 2 analog ch; ADAT optical present, but only 2 channels can be processed
• Q20 — 2 analog ch; ADAT optical present, but only 2 channels

Eventide

• H9000 — 8 analog I/O ↔ 8-ch ADAT
• H8000 / H8000FW — 4 analog I/O; ADAT present, but not 8 analog channels

Sony

• DPS-V55 — 4 analog ch; no ADAT

Yamaha

• 01V96 — built-in 8×8 ADAT + ≥8 analog I/O

Behringer

• X32 + X-ADAT — 32×32 ADAT via 4 optical I/O banks; X-ADAT replaces the USB expansion card

Ensoniq

• DP/Pro + DI-Pro — 4 ch; AES/EBU + S/PDIF option, no ADAT

Kurzweil

• KSP8 + Analog I/O option + ADAT I/O option — 8 analog I/O ↔ 8-ch ADAT
• ADAT option alone does not qualify: stock KSP8 has only 4 analog inputs + 4 analog outputs.

i have a similar opinion for personal use. which brings up the question if you can demux and recombine 2 4-channel optical signals?

yes. at 44.1/48k you can receive two ADAT streams and repack e.g. channels 1–4 from each into 1 new 8-channel ADAT stream, provided both sources are clock-synchronous. it requires an active ADAT matrix/router, not an optical splitter/combiner. old RME HDSP Digiface + TotalMix can do exactly that and can run in Disconnect Mode afterwards. at 88.2/96k it cannot reduce two 4-channel S/MUX streams to one optical port because one port only carries four audio channels at double speed.

i was just looking for one and only find MADI based Pro Gear starting from 4k.

the RME 4x4 ADAT Router would be great, but it requires you to connect to a PC everytime to start it because it does not store presets.

if you know about an affordable 4*2 or 4*4 router which can do a real standalone mode, let me know.

(using word clock for the sources is not enough btw, the optical signal always has to be reclocked.)

RME's Mathias Carstens in 2015: "Development on the ADAT Router has stopped, the product is cancelled."

Friend-Chip DMX16 + 4× MQA => standalone and remembers presets, but its ADAT decomposition is into four stereo pairs per Lightpipe, rather than arbitrary individual mono channels.

=> MOTU LP32 (Mar '17–by Jan '25) IF you can find one

[IIO]

=> MOTU LP32

yep, just learned about it.

for my budget it is not old enough though and it has an external PSU, but glad to see that it actually exists.

X32 with adat card is option #2 but a bit big.

so apparently digi 002 rack:

Undocumented: analog 1–8 → ADAT output without FireWire has been independently reported and demonstrated; apparently fixed at the 002R's 44.1-kHz boot state. Not documented by Digidesign/Avid.
