Mackie Onyx 1620 Owner's Manual - Page 20

ONYX 1620 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: 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 flexibility for the mixdown stage. See Appendix B for a wiring diagram of these connectors. 54. FIREWIRE I/O OPTION MONO PLUG Channel Insert jack Direct out with no signal interruption to master. Insert only to first "click." MONO PLUG Channel Insert jack Direct out with signal interruption to master. Insert all the way in to the second "click." STEREO PLUG Channel Insert jack For use as an effects loop. (TIP = SEND to effect, RING = RETURN from effect) 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 sixteen 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 10 dB of 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. 53. RECORDING OUTS These two DB-25 connectors provide balanced direct outputs for channels 1-8 and 9-16, 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 analog 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, The card also provides a return for two channels from the DAW, 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 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.
