Microphones - Mackie Onyx 1640i Quick Start Manual

Microphones

Connect your microphones to the female XLR
connectors on channels 1-16. The microphone preamps
feature our Onyx design, with super high fi delity and
headroom. Professional ribbon, dynamic, and condenser
mics all sound excellent through these inputs.
Microphone-level signals are passed through these
splendid microphone preamplifi ers 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.
Never plug single-ended (unbalanced) micro phones,
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.
LOW CUT
All 16 channels have a low-cut switch that cuts bass
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 fi ltering it out makes the low
stuff you do want much more crisp and tasty.
Not only that, but the low-cut fi lter can help
reduce the possibility of feedback in live
situations and it helps conserve amplifi er
power.
Another way to use the low-cut fi lter is in
combination with the low EQ on vocals during
live performances. Many times, bass shelving
EQ can really benefi t 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.
EQUALIZATION
All 16 channels have a 4-band EQ, with
shelving-high, shelving-low, and peaking-high-
mid and low-mid. The frequency of the low-mid
can be adjusted from 100 Hz to 2 kHz, and the high-mid
from 400 Hz to 8 kHz.
EQ IN/OUT
This is a true hardware bypass of the Perkins EQ cir-
cuitry 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 specifi ed fre-
quency. 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.
INSERTS
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 benefi t from having
an external vocal compressor. Use standard 1/4" TRS
"insert" connectors, where tip=send, ring=return, and
sleeve=ground.
