A grounding-type plug has two blades and a third grounding prong.
The wide blade or the third prong are provided for your safety. If the
provided plug does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.
10. Do not overload wall outlets and extension cords as this can result in a
risk of fire or electric shock.
11. Protect the power cord from being walked on or pinched particularly at
plugs, convenience receptacles, and the point where they exit from the
apparatus.
12. Only use attachments/accessories specified by the manufacturer.
13. Use only with a cart, stand, tripod, bracket, or
table specified by the manufacturer, or sold with
the apparatus. When a cart is used, use caution
when moving the cart/apparatus combination to
avoid injury from tip-over.
14. Unplug this apparatus during lightning storms or
when unused for long periods of time.
15. Refer all servicing to qualified service personnel. Servicing is required
when the apparatus has been damaged in any way, such as power-
supply cord or plug is damaged, liquid has been spilled or objects have
fallen into the apparatus, the apparatus has been exposed to rain or
moisture, does not operate normally, or has been dropped.
16. This apparatus shall not be exposed to dripping or splashing, and no
object filled with liquids, such as vases or beer glasses, shall be placed
on the apparatus.
17. This apparatus has been designed with Class-I construction and must
be connected to a mains socket outlet with a protective earthing
connection (the third grounding prong).
18. This apparatus has been equipped with a rocker-style AC mains power
switch. This switch is located on the rear panel and should remain
readily accessible to the user.
19. The MAINS plug or an appliance coupler is used as the disconnect
device, so the disconnect device shall remain readily operable.
20.NOTE: This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is
no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorientorrelocatethereceivingantenna.
• Increasetheseparationbetweentheequipmentandthe
receiver.
• Connecttheequipmentintoanoutletonacircuitdifferentfrom
that to which the receiver is connected.
• Consultthedealeroranexperiencedradio/TVtechnicianfor
help.
CAUTION: Changes or modifications to this device not expressly
approved by LOUD Technologies Inc. could void the user's authority to
operate the equipment under FCC rules.
21. This apparatus does not exceed the Class A/Class B (whichever is
applicable) limits for radio noise emissions from digital apparatus as
set out in the radio interference regulations of the Canadian Department
of Communications.
ATTENTION — Le présent appareil numérique n’émet pas de bruits
radioélectriques dépassant las limites applicables aux appareils
numériques de class A/de class B (selon le cas) prescrites dans le
réglement sur le brouillage radioélectrique édicté par les ministere des
communications du Canada.
22. Exposure to extremely high noise levels may cause permanent hearing
loss. Individuals vary considerably in susceptibility to noise-induced
hearing loss, but nearly everyone will lose some hearing if exposed to
sufficiently intense noise for a period of time. The U.S. Government’s
Occupational Safety and Health Administration (OSHA) has specified
the permissible noise level exposures shown in the following chart.
According to OSHA, any exposure in excess of these permissible limits
could result in some hearing loss. To ensure against potentially
dangerous exposure to high sound pressure levels, it is recommended
that all persons exposed to equipment capable of producing high
sound pressure levels use hearing protectors while the equipment
is in operation. Ear plugs or protectors in the ear canals or over the
ears must be worn when operating the equipment in order to prevent
permanent hearing loss if exposure is in excess of the limits set forth
here:

carefully turn up the channel fader and
headphones level a little.
4. The mono channel gain affects the mic and the
line inputs. The stereo channel gain adjusts the
stereo line inputs. Adjust as desired, and make
sure that the OL LED does not come on during
the loudest passages.
Note: there are two hybrid channels [9/10 and
11/12 on the ProFX16 and 15/16 and 17/18 on
the ProFX22] that have both mono mic and
stereo line inputs. In these channels, the gain
control affects only the mic gain.
5. Repeat steps 1 to 4 for the other channels.
Instant Mixing
1. To get sound out of the speakers and into a
waiting world, engage a channel's L-R assign
switch, turn up that channel’s fader to the “U”
(unity gain) position,
and slowly bring up the
main fader
to a comfortable listening level.
2. Sing and play. You’re a star!
3. Bring in other channels as mentioned above.
USB
The USB connection allows you to play two channels
of audio from your computer, and to record the main
mix to your computer. This feature is explained more
thoroughly on pages 4, 9-10, 16 and 23.
Notes
For optimum sonic performance, the channel faders
and main fader should be set near the “U” (unity gain)
markings.
Turn down all faders before making connections to
and from your ProFX mixer.
When shutting down the system, turn off amplifiers or
powered speakers first. When powering up, turn them
on last. This will prevent the possibility of turn-on and
turn-off thumps heard in your speakers.
Save the shipping box and receipt! You may need
them someday.

You probably want to try out your new
mixer right away. Before you do, please
read the safety instructions on page 2,
then read this page, and the rest later.
Zero the Mixer
1. Turn down all knobs except the channel EQ and
pan knobs, and set all the faders fully down.
2. Set all channel EQ knobs, pan knobs, and the
graphic EQ sliders at their center detent.
3. Set all buttons to the “out” position.
4. Whistle a popular show tune.
Connections
If you already know how you want to connect the
mixer, go ahead and connect the inputs and outputs
the way you want them. If you just want to get sound
through the mixer, follow these steps:
1.
Plug signal sources into the mixer, such as:
• Microphonespluggedintothemicinputs.
Engage phantom power if your mics need
it. Check the mic's user manual to be sure.
• Line-levelsourcessuchaskeyboards,drum
machines, or CD players plugged into the
line-level inputs.
2 . Connect cords from the main outs to your
powered speakers or amplifier.
3. Plug in the mixer’s power cord to a live AC
outlet and turn on the mixer.
4. If you have powered speakers, turn them on.
Otherwise, hook up your passive speakers to
your amp with speaker cables, and turn it on.
Adjust your powered speaker or amplifier level
controls to however the
manufacturer
recommends. (This is usually all the way up.)
Set the Gain
1. Plug something into an input. This could be an
instrument, you singing or speaking, or a line
level source such as a keyboard or CD player.
2. Engage the channel's PFL Solo switch to view
the input level via the main meters.

Introduction
Awesomely unheard of features
Powerful on-board FX engine and four
individual compressors
InpursuitoftheultimateMackie“do-it-all”live
sound mixer, we threw in the kitchen sink and packed
this bad boy with a full set of processors allowing you to
travel “rack free” while still making professional
sounding mixes.
Forstarters,weaddedourpatentedRunningManFX
processors(RMFX™) featuring 16 “gig-ready” effects
right into the board. This does not include useless
effects such as “the warbler” or the “insanity delay”, but
rather a suite of quickly accessible and useable reverbs,
choruses and delays that make enhancing your mix a
breeze.
The ProFX16 and ProFX22 also have four single knob
compressors to stop the dynamic signals from poking
out of the mix. They are located on the last four mono
mic inputs so that the most critical signals (such as
vocals, snare drum, the occasional jaw harp or
mountain goats) may be addressed.
Bottomline?YouhaveanawesomemixerwithMackie
sound quality, “built-like-a-tank” build quality and a
recording and processing feature set that is
unparalleled. Congratulations... and happy mixing!
USB Recording and Playback
TheProFXSeriesMixersfeaturea2x2USBrecording
and playback function. This means two signals may be
recorded simultaneously and a stereo mix returned to
the mixer for playback.
There is a switch in the master section labeled USB
OUT that allows for some powerful and flexible routing.
The default switch configuration allows the L-R mix to
be recorded for convenient stereo mixes of the show.
Or it routes subgroups 1-2 over the USB connection to
your favorite DAW software for an alternate 2-track
recording when the USB OUT switch is engaged.
For playback, there is a switch in the master section
labeled 2-TRACK RETURN. This switch changes the
standard dual RCA inputs to main (tape, switch
disengaged) to stereo USB to main (USB, switch
engaged).This is an extremely convenient function for
playing music over the main mix from a computer. We
prefertojamsomeJohnny'TheManinBlack'Cashin
between bands at the local rock clubs. But feel free to
play whatever you want, unless it's... ah, never mind, we
won't go there!
Another cool feature of the ProFX is routing the
stereo USB return to the last stereo channel of the
mixer. This is a mighty fine tool for a number of live and
recording uses. For example, playback through the
stereo channel allows the EQ to be utilized to sweeten
the sounds. It may also be used for overdubbing by
sending music to the musicians' headphones through
the auxes.
