Install in accordance with the manufacturer's instructions. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. [. . . ] Trouble is, adding low EQ also boosts stage rumble, mic handling clunks and breath pops from way-down low. Applying low-cut removes all those problems, so you can add low EQ without blowing your subwoofers. 16 Onyx 1620i 20. 1­8 only) Mostmodernprofessionalcondensermicsrequire 48V phantom power, which lets the mixer send lowcurrentDCvoltagetothemic'selectronicsthroughthe same wires that carry audio. (Semi-pro condenser mics often have batteries to accomplish the same thing. ) "Phantom" owes its name to an ability to be "unseen" bydynamicmics(ShureSM57/SM58, forinstance), which don't need external power and aren't affected by it anyway. Press this switch in if your microphone requires phantom power. (Always check the position of this switch before connecting microphones. ) Never plug single-ended (unbalanced) microphones, or ribbon mics into the mic input jacks if phantom power is on. Do not plug instrument outputs into the mic XLR input jacks with phantom power on, unless you know for certain it is safe to do so. Be sure the main level [55] is turned down when connecting microphones to the mic inputs when phantom power is turned on, to prevent pops from getting through to the speakers. 22. SEND FIREWIRE PRE/POST Each channel of the mixer can send a FireWire output to your computer or DAW. The FireWire output from each channel can be tapped before (pre) or after (post) the channel EQ. If you want the mixer EQ to affect the FireWire recording, then set this switch to post. This is useful in recording channels in a studio (where the recording includes the beneficial effect of our Perkins EQ). If you would rather record the straight signals from a live performance, and EQ them later in your DAW, then set this switch to pre. This is good for live work, where you may have added EQ to adjust for the room, and yet not want this added to your recording. 23. INPUT (LINE or FW 1-2) Channel15and16caneitherbefedfromthe1/4" line level inputs, or by two outputs from a computer via FireWire. This switch lets you choose which to use. Either way, the channels receive line-level analog audio signals just prior to the gain control, so channel setup, gain adjustment and EQ adjustment are the same for line or FireWire. This is useful for virtual instruments that want to be "just another channel" among hardware instruments. 21. GAIN CONTROL If you haven't already, please read the level-setting procedure on page 3. The gain knobs adjust the input sensitivity of the mic and line inputs. This allows signals from the outside world to be adjusted to run through each channel at optimal internal operating levels. If the signal originates through the mic XLR jack, there will be 0 dB of gain with the knob fully down, ramping to 60 dB of gain fully up.

ClicktheAudioDevicestab, andselect Onyx i in the "Properties For" drop-down box. 5. Here you can see the settings for the mixer. You can also choose it as your default input or output, as well as designate it to be used for system sound output. [. . . ]
