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.

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

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.

About this manual:

This manual covers both the DFX•6 and DFX•12 mixers. They share the same design and
operate in the same way, except that the DFX•12 has 2 more mono channels than the DFX•6,
and it has 2 stereo line-only channels.

Absolutely most important pages:

Before connecting and using your mixer, please read the Safety Instructions
on page 2. Before you start mixing, please read the Quick Start section starting
on page 4. It’s a list of steps that will familiarize you with the mixer and help you

set up a basic performance.

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 DFX Mixer is designed to set up quickly
and operate intuitively — but please, read the Safety Instructions on page 2,
and then read these two pages!

First you will zero the console, then make the connections, set the levels and
tweak the mix.

1. ZERO THE CONSOLE:

1. Turn everything off, including the mixer’s
POWER switch and PHANTOM POWER
switch.

2. Turn down the channel strip GAIN, AUX 1
and AUX 2 knobs, and faders.

3. Center the channel strip EQ and PAN
controls.

4. Push the channel strip MUTE switches down.

5. Set the channel strip LOW CUT switches up.

6. Center the STEREO GRAPHIC EQ sliders.

7. Turn down the MASTER AUX SEND knobs,
and the AUX RETURN faders.

8. Turn down the MAIN MIX faders.

9. Now you are ready to make the
connections, see the next page.

2. MAKE THE CONNECTIONS:

4. TWEAK THE MIX:

1. Connect your amplifier’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 1/4" TRS cables, make
connections from your mixer’s MAIN OUT
to your amplification system’s line inputs.

4. Make connections from your microphones
and instruments to the mixer: Connect
balanced microphones to the mono channel
MIC jacks. (For condenser microphones,
engage the PHANTOM POWER switch,
located just above the meters). Connect
line-level instruments (synthesizers, guitar
effects, direct boxes) to the mono or stereo
channel LINE IN 1/4" TRS jacks.

5. ZERO THE CONSOLE as shown on the
previous page.

6. Turn all the power switches on, leaving the
amplifier’s switch for last.

7. Turn up the MAIN MIX faders to the
“–30” label, for now. We’ll crank it later on.

8. Now you are ready to set the levels:

3. SET THE LEVELS:

1. Choose one of the microphones or instru­ments you connected. Make some noise. If
it’s a microphone, sing at your normal
singing volume. If it’s a synthesizer, play it
at its normal output level.

2. While making noise, turn up that channel’s
GAIN control until the adjacent LEVEL
SET LED starts a-blinking.

3. Disengage (up) that channel’s MUTE.

4. Raise that channel’s fader to unity gain
(“U” label). You should be hearing your
noise now.

5. If necessary, apply channel EQ changes.
(You may need to compensate for level
changes with the channel fader.)

6. Check that the channel’s OL LED does not
come on. If it does, reset the GAIN and
adjust the EQ if required.

7. Repeat steps 1 through 6 for the remaining
active channels.

8. Stop making noise. Everyone: start making
music.

9. Now you are ready to tweak the mix:

1. Engage MUTE on all channels except your
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.

4. Now that you have a rough mix going, turn
up the MAIN MIX faders to a comfortable
listening level.

5. If the overall mix has an equalization
problem, make adjustments to the STEREO
GRAPHIC EQ. If an individual channel is
the problem, use its channel EQ instead.

6. Use the channel AUX 2/EFX knobs to send
signals to the EMAC internal effects
processor (and to any external effects
processor you might have). Then adjust the
AUX 2/EFX RETURN fader and experiment
with adding some effects to your main mix.

7. If you are playing into the CD/TAPE input,
try using the VOCAL ELIMINATOR to hear
its effect on centered vocals and start up a
bit of audience mass-Karaoke.

8. Depending on how much time you’ve got,
keep tweaking. Walk the room to see how it
sounds away from your mixer.
Keep tweaking.

KNOW THESE THINGS:

• Never listen to loud
music for prolonged
periods. Please see “Safety
Instructions” on page 2 for
information on hearing
protection.

• Never plug amplifier outputs into anything
except speakers.

• Never use guitar cables to connect amplifi­ers to speakers.

• Before making connections to an external
amp or reconfiguring 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.

• When you shut down your equipment, turn
off any external amplifiers first. When
powering up, turn on the amplifiers last.

• Change your engine oil every 3,000 miles
and rotate your tires for even wear. Dad
would be proud of you.

• Save the shipping box and packing material!
You may need them someday, and you probably
don’t want to have to pay for that again.

The DFX Mixer is equipped with rugged, low
noise, phantom-powered microphone pream­plifiers, providing up to 50 dB of pounding
crystal-clear amplification. Their balanced cir­cuitry rejects all manner of extraneous
interference. Professional condenser, dynamic,
and ribbon mics 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.

2. LINE IN (FOR MONO CHANNELS)

These inputs can accept 1/4" TRS balanced
and 1/4" TS unbalanced plugs from any line­level instrument, effects device, or tape player.
The line inputs share circuitry (but not phan­tom power) with the mic preamps, and can be
driven by virtually any line-level signal.

The DFX Mixers provide +48 VDC phantom
powering on pins 2 and 3 of all the mono chan­nels’ XLR MIC inputs (not the stereo channels).
This can be turned on or off using the PHANTOM
POWER (31) switch on the right side of the mixer.

DO NOT connect a line­level device to a MIC input
with the phantom power
switched on. This could
damage the device. Use the
LINE IN (2, 3) jacks instead.

3. LINE IN (FOR STEREO CHANNELS)

These inputs can accept 1/4" TRS balanced
and 1/4" TS unbalanced plugs from any line­level instrument, effects device, or tape player.

When connecting a stereo device (two
cords), use both the left (mono) input and the
right input.

When connecting a mono device (just one
cord), always use the left (mono) input and
plug nothing into the right input. A trick called
“jack normalling” causes the signal to appear
on both sides.
