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. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. [. . . ] 1-8) The high-mid EQ provides up to 15 dB of boost or cut at 2. 5 kHz, anditisflatatthedetent. 0 MidrangeEQisoftenthought of as the most dynamic because the frequencies that define any particular sound are almost always found within this range.

This determines the center frequency for the EQ filter, and allows you to zero in on the precise narrow band of frequencies you want to have affected by the low-mid EQ [28].

AUX SENDS 1-4 These controls allow you to set up to four independent mixes, typically for running stage monitors or external effects processors. The controls are off when turned fully down, deliver unity gain at the center, and can provide up to 15 dB ofgainturnedfullyup. Chancesarethatyouwillnever need this extra gain, but it's nice to know that it's there if you do. Aux Sends 1-4 [6] are line-level outputs, and are used if you want to connect external processors, powered stage monitors, or external power amps with passive stage monitors. Aux Returns 1-4 [7] are line-level inputs, typically used to return the output from external processors back to the main mix. For example, if you are running stage monitors, and someone wants "more me, and less them, " adjust these carefully. The aux sends can either be pre or post fader, depending on the position of the aux pre/post switches [46]. For stage monitor work, use pre, so the stage monitors do not increase in volume when the channel level is adjusted. In this way, the feed to external processors will vary with the channel level, keeping them in the same ratio (wet/dry). 33. MUTE switch and ALT 3­4 Thedual-purposemute/alt3-4switchisaMackie signature. When Greg was designing our first product, hehadtoincludeamuteswitchforeachchannel. Mute switches do just what they sound like they do. "Why not have the mute button route the signal somewhere else useful, like a separate stereo bus?" So mute/alt 3-4 really serves two functions--muting (often used during mixdown or live shows), and signal routing (for multitrack and live work) where it acts as an extra stereo bus. To use this as a mute switch, all you have to do is not use the alt 3-4 outputs [14]. Then, whenever you assign a channel to these unused outputs, you'll also be disconnecting it from the main mix, effectively muting the channel. The mute switch also disconnects the channel from the post-fader aux send bus. [. . . ] The Onyx 1620i will only work with the 2. 0 driver, so if you have an OS before 10. 4. 11, you will need to check your system for updates from the nice folks at Apple. Go to the applications folder, open the utilities folder, anddouble-click"AudioMIDISetup. " 8. In your audio software applications, select and activate the inputs from the mixer and outputs to the mixer. 4. ClicktheAudioDevicestab, andselect Onyx i in the "Properties For" drop-down box. 5.
