class A/de class B (selon le cas) prescrites dans le règlement sur le brouillage
radioélectrique édicté par les ministere des communications du Canada.
18 .
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 a
permanent hearing loss if exposure is in excess of the limits set forth here.

QUICK START
We know you can’t wait to
get the show on the road.
Who has time to read a
booooring manual? That’s
fine — the CFX Mixer is
designed to set up quickly and operate intuitively — but please, READ THIS PAGE!

MAKE THE CONNECTIONS:
1. Connect your amp’s outputs to your
speaker inputs (unless, of course, you have
powered monitors).
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, make connections from your mixer’s

amplification system’s line inputs.
4. Make connections from your microphones
and instruments to the mixer: Connect
balanced microphones to the mono channel

jacks. (For condenser microphones,
engage the

line-level instruments (synthesizers, guitar
effects, direct boxes) to the mono or stereo

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 Mixer is equipped with rugged, low
noise, phantom-powered microphone preamplifiers, providing up to 50 dB of crystal-clear
amplification. 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.
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
filters. 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.
These unbalanced jacks are configured thusly:
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 chan-
