23. TALKBACK MIC

This is where you plug in your talkback microphone,
which you can use to communicate with the talent
through the headphone outputs. This female XLR con-
nector has +48 VDC phantom power always applied, so
you can use dynamic or condenser microphones.
Note: Almost all dynamic microphones can be used with
phantom power, but you might want to check the docu-
mentation that came with your microphone to be sure.

24. CONTROL RM MONITORS A/B

These 1/4" TRS jacks provide a balanced line-level
signal that can be used to provide a monitor mix to a
pair of powered studio monitors, or an additional head-
phone mix to a headphone amplifier. The A and B stereo
outputs are identical, but they can only be used one at
a time (switched with the MONITOR A/B Select Switch
[19] or the MON A/B Footswitch [32]). This is useful
for comparing two different pairs of monitor speakers.
The signal at the CONTROL RM MONITORS output
is the same as the BALANCED LINE-LEVEL OUTPUTs
1 and 2 by default. You can use the monitor outputs for
the DAW's main stereo mix, while keeping outputs 3-8
free for other uses, such as sending to a personalized
monitoring system (when preferred over the built-in
headphone amp system).
Note: You can select any odd/even pair of analog out-
puts, any stereo headphone out, or the stereo S/PDIF_
AES/EBU output as the source for the Control Room
Monitors in the Console "Settings" window.

25. MIDI IN/OUT (1 and 2)

These are standard 5-pin DIN MIDI connectors for
sending and receiving MIDI commands. When a MIDI
controller is connected to the 1200F, it appears as a MIDI
device in the DAW software application. They can be used
for a MIDI fader controller, a MIDI keyboard or drum
pad, or any other computer-related MIDI equipment.

The screenshot below shows how the Onyx 1200F ap-
pears in the Settings/MIDI Devices tab in Tracktion as a
MIDI device.
On a Mac, it appears in the Audio MIDI Setup utility,
found in the Applications/Utilities folder.
26. FIREWIRE
FireWire (a.k.a. IEEE 1394) is a high-speed serial
I/O interface for connecting digital devices, with more
than 30 times the bandwidth of USB 1.1. There are two
FireWire connections, so you can install the Onyx 1200F
in a daisy-chain fashion consisting of, for example, the
host computer, the Onyx 1200F, an external FireWire
hard drive, etc.
The FireWire interface provides up to 64 individual
streams of digital audio I/O at 48 kHz to your DAW soft-
ware application.
30 in/34 out digital streams at 48 kHz
16 in/16 out digital streams at 96 kHz
8 in/8 out digital streams at 192 kHz
