Apogee Electronics,
manufacturer of digital audio conversion systems, is now shipping an updated 96 kHz
AES/EBU interface card for users of its Trak2 2-channel mic pre/conversion system.
The AES8+ "high density" card is the latest in the series of AMBus (Apogee Multimedia
Bus) cards that add almost any digital audio interface to the company's AD-8000 series
and Trak2 external conversion systems. The AD-8000 features four slots and the Trak2
two, and format conversion can also be carried out between any installed interfaces in
real time.
The AES8+ I/O card provides eight channels of AES/EBU-compatible signals in and out in
"single-wire" format or four channels in "double-wire", in addition to the on-board single-
wire AES/EBU capability built into the converters, providing both "double-wire" and
"single-wire" operation at high sample rates (88.2 and 96 kHz) for use with the Trak2.
When used with recorders such as the Sony PCM-800 or other multi-channel recorders
with AES interfacing, the card also allows "bit-splitting" formats which spread high resolution
signals across multiple 16-bit tracks.
The AES8+ card supports eight channels of "single-wire" AES/EBU, up to 24 bits at up to
96 kHz sample rate; four channels of 24-bit Double-Wire AES I/O at 88.2/96 kHz sampling;
four channels of 24 bits each bit-split on to an 8-track 16-bit recorder at 44.1 or 48
kHz sampling (utilizing Rane's PaqRat format, which is available on other Apogee converters
from the AD-1000 onwards); and two channels of 24-bit, 88.2/96 kHz audio bitsplit
on to an 8-track 16-bit recorder at 44.1 or 48 kHz sampling, in Apogee's ABS96 format,
as used on the Rosetta and PSX-100.
The AES8+ card is available now, with a US MSRP of $795 and replaces the existing AES8
card at the same price.
