APOGEE AMBUS-SDIF EXPANSION CARD

Multimedia Bus expansion card for the Apogee AD- 8000 8-channel
24-bit digital audio conversion system

THE SDIF-2 AMBUS CARD is an optional Apogee Multimedia Bus expansion card
for the Apogee AD- 8000 8-channel 24-bit digital audio conversion system and other
AMBus-equipped systems, enabling eight channels of audio data to be transferred
between the AD-8000 and a digital system, such as DASH open-reel digital recorders,
that supports the Sony SDIF-2 interface format.
Owners of DASH-format open-reel digital multitrack machines such as the Sony 3324,
3348 and 3348HR can now enjoy the benefits of enhanced Apogee quality digital audio
conversion, thanks to the AMBus SDIF-II card and associated wiring harness.
The Sony 3348HR, for example, can be purchased without converters at a substantial
cost saving, making the AD-8000 particularly attractive for potential purchasers ? especially
as the regular Sony converters offer only 20-bit operation. Purchasing AD-8000 units with
the SDIF card, on the other hand, delivers full 24-bit resolution.
The SDIF card has an associated wiring harness that enables up to six AD-8000 converter
systems to be interfaced with a multitrack recorder.
The SDIF card also supports Apogee Bit-Splitting, which uses multiple 16-bit tracks to
store high-resolution data. This means that existing 3324 and 3348 owners can enjoy 20-
or 24-bit resolution: the 3324 can record 12 tracks of 24-bit or 18 tracks of 20-bit, while
3348 owners can handle 24 tracks of 24-bit or 36 tracks of 20-bit.
Utilizing Apogee?s AMBus structure built into the AD- 8000, you can easily interface the
AD-8000 to the vast majority of industry standard interfaces such as ADAT, TDIF, ProTools,
and many others, performing multiple format conversions between installed interfaces and
distributing signals to several different types of device simultaneously.
Apogee Bit-Splitting (ABS)

The SDIF-2 card includes two ?bit-splitting? formats which split high resolution signals among
multiple 16-bit data paths. Thus the SDIF-2 card supports the following digital audio formats:
1. 8 channels of 24 bit data (16 or 20 bits with UV22, and bit-splitting OFF)
2. 4 channels of 24 bits each (ABS ?4/24?, Rane?s PaqRat format) formatted as eight 16-bit
data paths
3. 6 channels of 20 bits each (ABS ?6/20? format) formatted as eight 16-bit data path.
Full PaqRat capability is provided in 4/24 mode, enabling you to create or replay recordings that
are completely compatible with Rane?s PaqRat equipment or with the PaqRat-compatible mode
of the enhanced ?Platinum Edition? Apogee AD-1000.
The 4/24 mode (four channels of 24 bits on eight 16-bit data paths) delivers the first 16 bits of a
24-bit signal on the first 16-bit path, and the remaining bits on a subsequent path along with a
marker tone.
An additional feature of the 4/24 mode is the ability to transfer eight simultaneous 24-bit channels
by using two 8-channel 16-bit paths (and thus two SDIF-2 cards).
The 6/20 mode allows six channels of 20-bit data to be sent via eight 16-bit paths ? ideal for 5.1
mixing for DVDVideo release, where the 20/48 format is very common.

The Tascam LA-40 MKIII has been primarily designed to provide matching capabilities between professional equipment and semi-professional or consumer equipment. It consists of four RCA inputs and outputs (–10 dBV, unbalanced) as well as four XLR inputs and outputs (+4 dBu/–20 dBu, balanced) which enable the user to connect for instance four tracks of a multitrack recorder (ins and outs) to a balanced mixer ensuring optimum level and impedance matching. Also, a switch matrix allows channels to be linked, utilizing the converter as a distribution amplifier for splitting signals to multiple recorders, or for multizone sound routing applications.

Switches on the bottom panel allow to select a nominal level of +4 dBu or –20 dBu for each channel and ±12 dB trim pots on the front panel make perfect level matching easy. LEDs on the front panel indicate signal presence for each channel. The LA-40 MKIII has also ground lift switches for each channel and a combined master switch to avoid ground loops.
