Mackie Onyx 1640i Quick Start Guide - Page 9

Microphones Connect your microphones to the female XLR connectors on channels 1-16. The microphone preamps feature our Onyx design, with super high fidelity and headroom. Professional ribbon, dynamic, and condenser mics all sound excellent through these inputs. Microphone-level signals are passed through these splendid microphone preamplifiers to become line-level signals. 48V PHANTOM POWER Press the 48V phantom power switch if your microphones need it. An LED lights just above the button to indicate that phantom power is active on that channel. Most modern professional condenser mics require 48 V phantom power, which lets the mixer send low-current DC voltage to the mic's electronics through the same wires that carry audio. EQ IN/OUT This is a true hardware bypass of the Perkins EQ circuitry to insure that there is no coloration of the signal if the EQ is not needed. When this button is out, the EQ controls have no effect on the signal. You may use this switch to make an A/B comparison between the EQ'd signal and the signal without EQ. The 4-band equalization has low shelving at 80 Hz, low mid peaking, sweepable from 100 Hz to 2 kHz, high mid peaking, sweepable from 400 Hz to 8 kHz, and high shelving at 12 kHz. "Shelving" means that the circuitry boosts or cuts all frequencies past the specified frequency. For example, rotating the low EQ knob 15 dB to the right boosts bass frequencies starting at 80 Hz and continuing on down to the lowest note you have ever heard. "Peaking" means that the frequencies around the center frequency are less affected by the EQ the further away they are. Never plug single-ended (unbalanced) microphones, INSERTS 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 are certain it is safe to do so. All 16 channels have insert jacks on the rear panel. These allow you to send the mic and line signals out to an external device, and back in again on the same connector. For example, vocals benefit from having LOW CUT an external vocal compressor. Use standard 1/4" TRS "insert" connectors, where tip=send, ring=return, and All 16 channels have a low-cut switch that cuts bass sleeve=ground. frequencies below 75 Hz of the mic and line inputs. This will reduce any thumps and bangs due to stage noise and rumble, and mic handling. We recommend that you use low-cut on every microphone application except kick drum, bass guitar, or bassy synth patches. These aside, there isn't much down there that you want to hear, and filtering it out makes the low XLR Mic Inputs 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 INSERT INSERT INSERT INSERT INSERT INSERT INSERT INSERT INSERT INSERT INSERT INSERT INSERT INSERT INSERT INSERT LINE BAL/UNBAL ONYX MIC PRE LINE BAL/UNBAL ONYX MIC PRE LINE BAL/UNBAL ONYX MIC PRE LINE BAL/UNBAL ONYX MIC PRE LINE BAL/UNBAL ONYX MIC PRE LINE BAL/UNBAL ONYX MIC PRE LINE BAL/UNBAL ONYX MIC PRE LINE BAL/UNBAL ONYX MIC PRE LINE BAL/UNBAL ONYX MIC PRE LINE BAL/UNBAL ONYX MIC PRE LINE BAL/UNBAL ONYX MIC PRE LINE BAL/UNBAL ONYX MIC PRE LINE BAL/UNBAL ONYX MIC PRE LINE BAL/UNBAL ONYX MIC PRE HI-Z BAL/UNBAL ONYX MIC PRE HI-Z BAL/UNBAL ONYX MIC PRE Inserts TALKBACK MIC +48v BALANCED R L MAIN OUT BAL /UNBAL L MONO MAIN INSERT (TIP=SEND RING=RTN) L TAPE IN OUT L CTRL-RM OUT BAL /UNBAL L SUB OUT BAL/UNBAL 3 1 AUX RETURN BAL/UNBAL 4 3 2 L L L 1 L AUX SEND BAL/UNBAL 5 3 1 (MONO) (MONO) (MONO) (MONO) 4 2 6 4 2 MAIN OUTPUT LEVEL +4dB MIC POWER ON R R R R +6 OO FIREWIRE R R R R 9-16 RECORDING OUTS POST GAIN PRE INSERT BALANCED 1- 8 stuff you do want much more crisp and tasty. Not only that, but the low-cut filter can help reduce the possibility of feedback in live situations and it helps conserve amplifier power. Another way to use the low-cut filter is in combination with the low EQ on vocals during live performances. Many times, bass shelving EQ can really benefit voices. Trouble is, adding low EQ also boosts stage rumble, mic handling clunks, and breath pops. Low-cut removes all of those problems so you can add low EQ without blowing your subwoofers.
