The twelve mic/line inputs, two S/PDIF or AES inputs,
eight digital A, and eight digital B inputs are routed
directly to the software application via the FireWire con-
nection. These streams are not affected by the DSP Mixer
in the Onyx 1200F Console (see the Figure on page 9).
The FireWire interface also provides a return from the
DAW for the eight analog outputs, two S/PDIF or AES
digital outputs, eight digital A (ADAT) outputs, eight
digital B (ADAT) outputs, and four stereo headphone
outputs, which can be routed back to their respective
outputs. You can use the control room outputs to moni-
tor the stereo mix from the DAW application through
your control room monitor speakers.
The FireWire interface works with both PC and Mac.
As an added bonus, we include a free copy of Tracktion,
our multitrack recording and sequencing software ap-
plication for PC and Mac.
Tip:
If your laptop or desktop computer does not have
a FireWire connection, you can purchase a PCI or
PCMCIA FireWire card (or FireWire ExpressCard) and
install it in your computer easily and inexpensively.
27. AES/EBU IN/OUT
These are XLR connectors that send and receive two
channels of digital audio in the AES/EBU professional
digital format.
AES/EBU OUT transmits two-channels of digital
audio, which appear as outputs 33 and 34 in the DAW
software application.
AES/EBU IN receives two-channels of digital audio,
and appears as DAW inputs 29 and 30 in the Onyx 1200F
Console.
The AES/EBU I/O on the Onyx 1200F supports sample
rates up to 192 kHz.
Note:
The AES/EBU or S/PDIF inputs are selected in
the Console’s Settings window. Only one of these inputs
can be selected at a time.
The AES/EBU and S/PDIF outputs mirror each other
and are always active.
28. S/PDIF IN/OUT
These are RCA connectors that send and receive two
channels of digital audio in the S/PDIF (

The S/PDIF inputs share the same
two digital streams with the AES/EBU
inputs. You can select which input to
use in the Settings tab in the Onyx
1200F Console (Digital Input: S/PDIF
coaxial or AES/EBU XLR). The S/PDIF
and AES/EBU outputs are always active and carry the
same stereo signal.
S/PDIF OUT transmits two-channels of digital audio,
which appear as outputs 33 and 34 in the DAW software
application.
S/PDIF IN receives two-channels of digital audio, and
appears as DAW inputs 29 and 30 in the Onyx 1200F
Console.
The S/PDIF I/O on the Onyx 1200F supports sample
rates up to 192 kHz.
Note:
Transferring digital audio over a cable generates
EMI (electromagnetic interference) around the cable.
Use high-quality 75-ohm coaxial cable for the S/PDIF
connections to minimize the EMI noise radiated around
the cable.
Tip:
A 75-ohm composite video cable can be used for a
S/PDIF connection.
In general, the shorter the cable length, the less
effect it has on the quality of the signal. The maximum
recommended length for a S/PDIF cable is limited to
10 meters (about 32 feet).
Note:
Strictly speaking, S/PDIF is
limited to 20-bits because four bits
are reserved for “user bits.” However,
in the Onyx 1200F, the four user bits
are used for digital audio and 24-bits
are transmitted (this is an accepted
optional implementation of S/PDIF).
