ONYX 1200F
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 (see illustrations below).
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 1200F has a built-in 75-ohm
termination), you can purchase a BNC 75-ohm terminator
for this purpose.
Note: 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 the devices to receive
a clock edge at the same time.
9. ADAT IN/OUT (A/B)
These four Toslink connectors provide optical digital
inputs and outputs using the ADAT lightpipe format. At
higher sample rates, the signal is multiplexed using the
S/MUX format.
At 44.1 kHz, and 48 kHz sample rates: Sixteen channels
of inputs and outputs are provided (eight channels on
digital A and eight channels on digital B).
TIP: If you are recording a live show, you can use the
second ADAT OUT to make a backup recording to a
separate, independent recorder, “just in case.”
At 88.2 kHz and 96 kHz sample rates: Four channels
are provided on the A connectors, and four channels are
provided on the B connectors, as specified by the S/MUX
II protocol for doubled sample rates.
At 176.4 kHz and 192 kHz sample rates: The ADAT I/O
is disabled at these higher sample rates.
If you want to use the 88.2/96 kHz
sample rates, check your recording
device’s owner’s manual to make sure
the optical inputs support the S/MUX
format.
0. EXTERNAL WORD CLOCK IN/OUT
These BNC connectors send and receive word clock
signals.
This WORD CLOCK IN connector receives word clock
from another device when the CLOCK SOURCE selector
on the front panel is set to WORD. Use this connector
when you want to slave the 1200F to an external master
word clock.
