Mackie Onyx 1220 Owner's Manual page 20

Special insert cables are available, specially designed
for this kind of insert jack. They are wired as follows:
ring
(TRS plug)
tip
sleeve
this plug connects to one of the
mixer's Channel Insert jacks.
Tip = Send (output to effects device)
Ring = Return ( input from effects device)
Sleeve = Common ground (connect shield to all
three sleeves)
Besides being used for inserting external devices,
these jacks can also be used as channel direct outputs;
post-TRIM, post-LOW CUT, and pre-EQ. This is an
unbalanced direct out, in contrast to the RECORDING
OUTS on the rear panel, which are balanced direct
outputs, post-TRIM, pre-LOW CUT.
Here are three ways you use the INSERT jacks:
MONO PLUG
Direct out with no signal interruption to master.
Insert only to first "click."
MONO PLUG
Direct out with signal interruption to master.
Insert all the way in to the second "click."
STEREO
PLUG
For use as an effects loop.
(TIP = SEND to effect, RING = RETURN from effect)
These two DB-25 connectors provide balanced direct
outputs for channels 1-4 and 5-12, respectively. They are
designed to be connected directly to a recorder's analog
inputs, and use the TASCAM standard pinout for analog
signal connections (the same standard used on the ana-
log cards for the Mackie D8B and Hard Disk Recorder).

The signal at the RECORDING OUTS comes just after
the input GAIN control, and before the Low-Cut switch,
INSERT jacks, and EQ. This way you can EQ a channel,
connect a compressor or other dynamics processor to
the INSERT jack, and adjust the channel fader to suit
your live mix, but it has no effect on the signal going to
the recorder. This provides maximum fl exibility for the
mixdown stage.
See Appendix B for a wiring diagram of these connectors.
Okay, we saved the best for last. 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. You can install the optional Onyx FireWire
interface card in this slot, which provides three
FireWire connectors for transferring digital audio to and
from your laptop computer or digital audio workstation
(DAW) with absolute zero latency.
The FireWire interface provides the direct outputs
for all twelve channels and the Left/Right Mix. The
Left/Right Mix is pre-fader at the FireWire output, so its
level is independent of the MAIN MIX fader (important
for live gigs). Instead, it has a rotary level control that
provides a 10 dB boost or cut for the Left/Right mix,
to optimize the level for the recorder or DAW. Use the
FireWire interface to record a live performance directly
to your laptop, which you can mixdown to a stereo mix
later. Or you can use it to turn your Onyx mixer into a
high-quality computer audio interface for your DAW.
The card also provides a return for two channels
from a DAW or laptop, which can be routed through the
CONTROL ROOM/PHONES SOURCE matrix (20) via
the FIREWIRE button, to monitor the computer audio
through your control room speakers or headphones
(or through the main speakers if ASSIGN TO MAIN
MIX (21) is selected).
The FireWire interface works with both PC (ASIO
for Windows XP) and Mac (Core Audio for Mac OS 10.3
or higher). As an added bonus, we include a free copy
of Tracktion, our multitrack recording and sequencing
software application for PC or Mac.
