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 employé pour alerter les utilisateurs de la présence d'instructions importantes pour le fonctionnement et l'entretien (service) dans le livret d'instruction accompagnant l'appareil.

15.This apparatus shall not be exposed to dripping or splashing, and no object ﬁlled 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 connection (the third grounding prong).

17.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.

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 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.

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
1.5	102
1	105	Greg screaming at Troy about deadlines
0.5	110
0.25 or less	115	Loudest parts at a rock concert

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 ﬁre or electric shock, do not expose this appliance to rain or moisture.

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 MKII mixer is designed to set up

quickly and operate intuitively — but please,

READ THIS PAGE!

ZERO THE CONSOLE:

1.Turn everything off, including the mixer’s

POWER switch and PHANTOM POWER switch.

2.Channel strip GAIN, AUX, EFX, and Fader down.

3.STEREO GRAPHIC EQ sliders centered.

4.MASTER AUX and EFX SENDS, and EFX RETURNS down.

5.Channel strip EQ and PAN controls centered.

6.Channel strip ASSIGN 1-2 and MUTE switches down.

7.Channel strip LOW CUT, PRE FADER, and ASSIGN 3-4 switches up.

8.SUB 1 ASSIGN LEFT, SUB 2 ASSIGN RIGHT down; all other SUB ASSIGN switches up.

9.MAIN MIX and SUB Faders down.

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 MAIN OUTS to your powered speakers or amp’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 TRS jacks.

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

6.Turn up the MAIN MIX Fader to the

“–30” label, for now. We’ll crank it up later on.

7.Turn up SUB Faders 1 and 2 to unity gain (“U” label).

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 until the adjacent ZERO LEVEL starts 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.Repeat steps 1 through 5 for the remaining active channels.

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

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 Fader 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 EQ instead.

6.Using channel EFX 2 (INT) and the EMAC EFFECTS PROCESSOR, experiment with adding some effects.

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.

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 passive 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. The same is true for powered speakers.

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

•Save the shipping box and packing material! You may need them someday.

PATCHBAY FEATURES

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 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:

	ring		SEND to processor
tip		(TRS plug)	“tip”
	sleeve
This plug connects to one of the			“ring”
mixer’s Channel Insert jacks.
			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-GAIN, post-LOW CUT, and pre-EQ. Here are three ways you can use the channel INSERT jacks:

MONO PLUG

Channel Insert jack

Direct out with no signal interruption to master. Insert only to first “click”

MONO PLUG

Channel Insert jack

Direct out with signal interruption to master.

Insert all the way in to the second “click”

STEREO

PLUG

Channel Insert jack

For use as an effects loop.

(TIP= SEND to effect, RING = RETURN from effects)
