17. POWER CONNECTION
This is a standard 3-prong IEC power connector.
Connect the detachable linecord (included in the box
with your interface) to the power receptacle, and plug
the other end of the linecord into an AC outlet. The
Onyx Blackbird has a universal power supply that can
accept any AC voltage ranging from 100 VAC to 240
VAC. No need for voltage select switches. It will work
virtually anywhere in the world. That's why we call it
a "Planet-Earth" power supply! It is less susceptible to
voltage sags or spikes, compared to conventional power
supplies, and provides greater electromagnetic isolation
and better protection against AC line noise.
Disconnecting the plug's ground pin is
dangerous. Don't do it.
18. FIREWIRE
FireWire (aka IEEE 1394) is a high-speed serial I/O
interface for connecting digital devices, with several
times the bandwidth of USB. There are two FireWire
connections so you can install the Onyx Blackbird in a
daisy-chain fashion consisting of, for example, the host
computer, the Onyx Blackbird, an external FireWire
hard drive, etc.
The FireWire interface provides 16 individual streams
of digital audio into your DAW at up to 96 kHz. These
originate from the physical inputs of the device:
the 8 x Onyx preamps and 8 x ADAT (S/MUX II) digital
inputs of the product itself.
Similarly, 16 streams of digital audio are routed back
into the device at up to 96 kHz, and made available
via its outputs. In the analog domain, those are main,
monitor, alternate and headphone 1-2 outputs. In
digital, those are the 8x ADAT (S/MUX II) digital
outputs on the rear panel of the device.
The FireWire interface works with both PC and Mac.
However, it requires installation of the Blackbird Con-
trol software (see the Quick Start section on page 3). As
an added bonus, we include a free copy of Tracktion 3,
our multitrack recording and sequencing software
application for PC and Mac.

19. WORD CLOCK IN/OUT
These BNC connectors send and receive word clock
signals. Use the word clock IN connector to slave the
Onyx Blackbird to an external master word clock.
Use the word clock OUT connector to make the Onyx
Blackbird the master word clock in a system of digital
devices.
Use 75 Ω coaxial cable when connecting a word clock
to the word clock in jack. If there is more than one
device to connect to the word clock, either use a master
word clock distribution box (preferred), which
distributes the master word clock to multiple devices
simultaneously, or use the word clock out to feed the
signal on to the next device in the chain.
The word clock out jack produces the word clock
signal for the selected clock source at the selected
sample rate.
The last device in a word clock chain must be
terminated. If the last device is not self-terminating
(for example, the word clock in connector on the Onyx
Blackbird has a built-in 75 Ω termination), you may
purchase a BNC 75 Ω terminator for this purpose.
Chaining the word clock out introduces delay
down the line. The more devices you have on
the chain, the more delay from the first to the
last device. It can work in some cases, but you really
want all of the devices to receive a clock edge at the
same time.
