IMPORTANT SAFETY INSTRUCTIONS
15.
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
This apparatus shall not be exposed to dripping or splashing, and no
object fi lled with liquids, such as vases, shall be placed on the apparatus.
16. This apparatus has been designed with Class-I construction and
must be connected to a mains socket outlet with a protective earthing

10. Protect the power cord from being walked on or pinched particularly
at plugs, convenience receptacles, and the point where they exit from
the apparatus.
11. Only use attachments/accessories specifi ed by the manufacturer.
12. Use only with a cart, stand, tripod, bracket, or
PORTABLE CART
WARNING
table specifi ed by the manufacturer, or sold with the
apparatus. When a cart is used, use caution when
moving the cart/apparatus combination to avoid

power switch. This switch is located on the rear panel and should remain
readily accessible to the user.
18. 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.
19. The MAINS plug or an appliance coupler is used as the disconnect
device, so the disconnect device shall remain readily operable.
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.
20.
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
suffi ciently intense noise for a period of time. The U.S. Government’s
Occupational Safety and Health Administration (OSHA) has specifi ed the
permissible noise level exposures shown in the following chart.
Duration Per Day Sound Level dBA, Typical
In Hours Slow Response Example
8 90 Duo in small club
6 92
4 95 Subway Train
3 97
2 100 Very loud classical music

AVIS: POUR EVITER LES RISQUES D'INCENDIE OU
D'ELECTROCUTION, N'EXPOSEZ PAS CET ARTICLE
The lightning flash with arrowhead symbol within an equilateral
triangle is intended to alert the user to the presence of uninsulated
"dangerous voltage" within the product's enclosure that may be
of sufficient magnitude to constitute a risk of electric shock to persons.
Le symbole éclair avec point de flèche à l'intérieur d'un triangle
équilatéral est utilisé pour alerter l'utilisateur de la présence à
l'intérieur du coffret de "voltage dangereux" non isolé d'ampleur
suffisante pour constituer un risque d'éléctrocution.
The exclamation point within an equilateral triangle is intended to
alert the user of the presence of important operating and maintenance
(servicing) instructions in the literature accompanying the appliance.
Le point d'exclamation à l'intérieur d'un triangle équilatéral est

A LA PLUIE OU A L'HUMIDITE
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.
WARNING — To reduce the risk of fi re or electric shock, do
not expose this appliance to rain or moisture.

MAKE THE CONNECTIONS:
1. Connect your amp’s outputs to your
speaker inputs (unless, of course, you have
powered loudspeakers).
2. Plug all the sound system components into
suitable AC outlets, properly grounded and
capable of delivering adequate current.
3. Using XLR or TRS cables, connect your
mixer’s

4. Make connections from your microphones
and instruments to the mixer: Connect
balanced microphones to the mono channel

engage the

TWEAK THE MIX:
KNOW THESE THINGS:
1. Engage

rhythm section (drums & bass).
2. Adjust the rhythm section’s channel faders
to get a good balance of levels.
3. Un-mute the other active channels and
adjust their faders.

up the

7. Depending on how much time you’ve got,
keep tweaking. Walk the room to see how it
sounds away from your mixer. Keep tweaking.
• Never listen to loud music for prolonged
periods. Please see “Safety Instructions” on
page 2 for information on hearing protection.
• Never plug amplifi er outputs into anything
except passive speakers.
• Never use guitar cables to connect amplifi ers to speakers.
• Before making connections to an external
amp or reconfi guring an amp’s routing, turn
the amp’s level (gain) controls down, turn
the power off, make the changes, turn the
power back on, and then turn the level controls back up. The same is true for powered
speakers.
• When you shut down your equipment, turn
off any external amplifi ers and/or powered
speakers fi rst. When powering up, turn on
the amplifi ers and/or speakers last.
• Save the shipping box and packing material! You may need them someday.

XLR BALANCED WIRING
At the risk of stating the obvious, this is
where you plug everything in: microphones,
line-level instruments, effects, headphones
and the ultimate destination for your sound:
PA system, tape recorder, etc.
MIC
The CFX MKII mixer is equipped with rugged,
low noise, phantom-powered microphone preamplifi ers, providing up to 50 dB of crystal-clear
amplifi cation. Their balanced circuitry rejects all
manner of extraneous interference. Professional
condenser, dynamic, and ribbon mics will all
sound excellent through these XLR inputs.
You can plug in almost any kind of balanced
mic that has a standard XLR-type male mic
connector.
These unbalanced jacks are confi gured thusly:

This plug connects to one of the
mixer’s Channel Insert jacks.

(TRS plug)
SEND to processor
RETURN from processor
Tip = Send (to effects device input)
Ring = Return (from effects device output)
Sleeve = Common ground (connect shield
to all three sleeves)
Specialty “Y” cables, developed just for these
jacks, are widely available.
Besides being used for inserting external devices, these jacks can also be used as channel
direct outputs; post-

LINE IN
The line inputs share circuitry (but not
phantom power) with the mic preamps, and
can be driven by balanced or unbalanced
sources at almost any level. You can use these
TRS inputs for virtually any signal you’ll come
across, from –25 dBu up to +38 dBu.
INSERT
This is where you connect serial effects
such as compressors, equalizers, de-essers or
fi lters. The send is low-impedance (150 ohms),
capable of driving any line-level device. The
return is high-impedance (10k ohms) and can
be driven by almost any device.
