Apogee AD-8000SE
A converter that turned up in the racks of the engineers whose names are on the records you already own.
Overview
The AD-8000SE is the Special Edition of Apogee's AD-8000 converter, and the best way to describe it is by the company it kept. Mix (January 2001, p.53) put Chick Corea on the page with an AD-8000SE and a MOTU 2408 in his Mad Hatter facility. The copy says the sound of 30 IPS two-inch tape had always been warmer and more attractive to him, and that with the AD-8000SE in line with a digital rig he could get that character back. That's an artist's endorsement in an Apogee ad, not a lab measurement. But it tells you what the box was sold to do.
A separate campaign, in EQ (June 2001, p.99), carried a second testimonial from songwriter Steve Kipner, photographed in his hillside studio with the AD-8000SE and a Trak2. Kipner's quote is the working-stiff version of the pitch: plug in, it sounds incredible, hardly any EQ needed. Again, advertising. Two different famous users in two different magazines over six months is a fair signal of how Apogee positioned the Special Edition at the turn of the millennium.
The AD-8000SE earned its reputation in rooms where conversion had to survive a full record. Bob Clearmountain's setup is the documented case. He ran six AD-8000SE units fitted with SDIF-2 cards, dedicated to A/D and D/A conversion for a Sony 3348HR, plus a seventh as the front end for his Pro Tools rig. The AMBus - Apogee's Multimedia Bus, which format-converts between digital audio protocols - let him bridge Pro Tools and the 3348HR with a Digi 8+ card in the control-room unit, four AES pairs running to the tape machine, and a Digidesign Universal Slave Driver handling timecode. Under normal tracking and mixing the 3348HR was clock master, leaning on the AD-8000's low-jitter clock. When transferring out of Pro Tools, the control-room AD-8000 supplied word sync over the AES pairs, so the signal path and the clock path stayed identical in length.
The Soft Limit circuit is the other half of the AD-8000SE story. In a mastering writeup, tracks were transferred into Pro Tools through an SSL G384 compressor and then an AD-8000SE. The songs that had already been mixed through an SSL skipped the compressor and were digitized through the AD-8000SE using Soft Limit instead. That's the feature doing the job it was designed for: catching peaks so a hot transfer doesn't have to be babied. Clearmountain's vocal chain on a Jonatha Brooke session ran a CAD Equitek E-300 or one side of an AKG C24 into an Avalon M5, out to a line input on the SSL, then to an AD-8000SE whose digital output fed the PCM-3348HR. At times a modified UREI LA3A sat in the path, padded at the output so the input could be driven harder for a better signal-to-noise ratio without overloading the output stage.
Apogee's own advertising in EQ (January 2002, p.11) called the Special Edition the "best-sounding converter in the industry" and ran a trade-in promotion: send in a qualifying converter, take thousands off a new AD-8000SE. That's marketing copy and should be weighed as such. The trade-in program does show Apogee working to move existing converter owners onto the Special Edition.
The documented record doesn't include a tidy spec sheet for the AD-8000SE. The available material is almost entirely about how it was used - which formats it bridged, which rooms it sat in, whose records went through it - rather than resolution figures, dynamic range, or pricing. Collectors chasing a number will have to look elsewhere. What the record does establish is a converter bought in quantity by people who could have bought anything, deployed as the glue between Pro Tools and digital tape, and trusted with the transfer stage of finished masters.
