QUICK STA RT UP
If you’re like most new owners, you’re probably in a hurry to plug your DX mixer
in and use it. Here are some brief instructions to get you going quickly. With the
mixer unplugged, turn the unit off and complete the following procedures:
CONNECTING AC POWER TO YOUR MIXER (Non-Powered Models Only)
Check and change if necessary the
AC Line Voltage to the proper voltage. The AC Line Voltage is listed
on the fuse holder in the AC connect
receptacle. To change the AC operating voltage remove and rotate the
fuse holder so that the desired volt-

age reads right side up. Use only a grounded (3 prong) power outlet to prevent a
shock hazard. This gives the quietest grounding for your mixer. Powered mod -
els do not offer 120/240 voltage switching. They must be ordered for the
appropriate line voltage.
CONNECTING INPUTS TO YOUR MIXER
For low level balanced devices such as microphones, plug into the
balanced MIC XLR input. Use a 3 conductor shielded mic cable. For
high output level devices such as Tape Recorders, CD’s, Keyboards
and Wireless mic receivers, plug into the LINE 1/4” input jacks. Use a
2 conductor shielded cable.
CONNECTING OUTPUTS FROM YOUR MIXER
Connect the L E F T / 3 and R I G H T / 4 balanced XLR outputs
to the balanced XLR inputs on your power amp. If your
power amp can not accommodate balanced XLR connections, there are unbalanced 1/4” phone jacks on the rear of
your D X Series mixer (except powered models).

TURNING YOUR MIXER ON
Adjust all faders and gain controls of your mixer to the off position. Adjust
all EQ tone controls—Hi, MID and LOW and the 9 Band Graphic EQ to
their center positions. Adjust all the Channel P A N Assign controls to
their center positions. Turn the mixer’s power switch to the on position
and check that the power indicator LED illuminates. Your mixer is now on
and ready to operate.
SETTING YOUR CHANNEL LEVELS
Bring up the level of the LINE MIC gain control until the channel peak
indicator LED PK illuminates, then back off this control by one number. It
is normal for the peak indicator to occasionally flash during use. Set the
L - R / 1 - 2 switch to the L-R STEREO MASTERS. Bring up the channel
fader level to a nominal setting of “0”, this is Unity Gain for the channel
fader.
SETTING YOUR MASTER LEVELS
Bring up the STEREO MASTER faders to the desired volume level, and
monitor the levels by depressing the L / R button in the M E T E R S s e l e c t
block.

1. LINE INPUT JACK - This 1/4” phone jack is designed
to accept unbalanced line or low level signals. This input
will accept both high and low impedance input signals. It
1
is sensitive enough to directly accept the output of a guitar or similar instrument with out the need for external
direct input boxes or preamplifiers, yet will also accept
line level signals such as pre amp outputs from ampli-
2
fiers or keyboard systems.
2. XLR MIC INPUT - The XLR input is designed for balanced low impedance (microphone) input signals. This
allows for long microphone cable runs without significant
3
signal or high frequency loss. The input channel consists of a balanced differential amplifier which works to cancel externally generated noise. The XLR connector is wired as per the industry standard, pin one is
ground, pin two is high (positive signal) and pin three is low (negative signal).
Phantom power is available on every XLR microphone input. This will allow you
to run condenser microphones directly off of your DX Series mixer. A switch
located in the master section will allow you to engage the phantom power.
NOTE: Make sure the phantom power is switched off before connecting or disconnecting microphones to your mixer. It is recommended that you allow the
phantom power to discharge for about 10 seconds before making any microphone connections.
3. DIRECT/INSERT JACK - The channel patch jack allows you access to that
channel for inserting different effects or signal processing equipment. Usually
this jack is used with such signal processing equipment as compressors,
limiters, delays, EQ’s, etc. These
devices can help with many problem
situations requiring special attention.

For instance, if you have a vocal input
requiring a very precise equalization (tone shaping) you may wish to “patch in” a
more elaborate equalizer than the standard tone controls found on the channels. This would allow you the ability to affect that particular channel without
affecting adjacent channels.
And, you achieve your objective of fine tuning that particular vocal. The jack is configured: Tip to return and Ring to
send.
To use the D I R / P A T C H for a
direct channel output, insert
the plug only halfway into the
jack.
Carvin offers the A P 1 cable which is a 6” adapter which plugs into the
DIR/PATCH giving a 1/4” jack for the “Send” and a 1/4” jack for the “Receive”
portions of the Patch feature.
4. GAIN CONTROL - The best way to use this control
is to start by rotating the gain control fully counterclockwise. Then while source material is active, bring up the
4
gain control until the peak indicator illuminates and then
back off until the peak PK indicator just stops flashing.
This provides the maximum usable gain for the input. If
5
the signal is too strong the red LED peak PK indicator
will light. Rotate the LINE / MIC gain control counterclockwise until the PK light just goes out. Setting the
input gain controls just below the peak threshold will set
6
the input gain to deliver just the right level to the channel. It is alright if the peak indicator occasionally flash-
1
es during use, as it is set to come on at -6dB below
clipping. Rotating the LINE / MIC gain control exces-
7
sively counterclockwise beyond the point at which the
PK light goes out will drop the signal too much and you

may not have enough gain, or the noise floor (hiss)

may become audible. Once this adjustment has been made you should not
need to adjust this control again unless the signal changes at the source.
5-8 CHANNEL EQ - The Channel Equalizer is a very precise set of tone controls. The H I or “Treble” control is at the top of the Channel Equalizer controls.
The M I D and MID sweep controls are in the center. And, the L O W or bass
control is at the bottom of this array. Use these
knobs to modify the tone of the signal feeding
this particular channel. It is most important that
you know that the flat (or neutral) setting for
each EQ control is “0” or (center detent). If you
have any doubt about how to set the them then
always set the channel EQ controls flat (i.e.
“ 0 ” ) .
How a tone control works is basically similar to
a volume control. The difference being that a
tone control literally controls the volume of a

shelf and therefore can be used to either
emphasize or quiet the low range of an input
signal. The M I D has a variable frequency
range from 300Hz to 5KHz this allows you to
fine tune the mid-range frequencies. This is
especially useful as the mid-range is usually
the most critical “problem range”. The EQ
controls allow you to adjust the volume ±12dB
at their center frequencies. Direct connection
of electric guitars usually sound best with full
MID cut (-12dB) at 500Hz, and full treble “H I”
boost (+12dB). Experimentation is in order.
Usually these controls are used as a means of compensating for the imperfect
response of various microphones in order to achieve the most natural sounding

9-12 MONITOR and EFFECTS BUS SENDS - The input channel’s monitor and effects
send controls are simply volume controls for setting up four “side mixes” which are independent of the main mix. They are used to set up mixes for stage monitors and various
effects units. Each channel has two monitor send controls (MON 1& MON 2). These
control the volume of that channel’s signal in the MON 1& MON 2 monitor mixes. The
monitor level control on each channel adjusts the relative volume of that channel in the
overall monitor mix. So, it is possible that you could set up a monitor mix that is entirely
different from the main mix. For instance, you might have a vocal “out front”, or louder,
in the MON 1 mix to allow a singer to concentrate on their vocals while feeding a relatively low level of that same vocal to the main mix. Since stage monitors are typically
right next to the microphones, they are usually the mix most susceptible to feedback during a performance. Because of this we recommended that you use caution when
adjusting monitor levels during a live performance. It takes a certain amount of “feel” to
set up a good monitor mix without getting ringing or outright feedback. However, with
experimentation and practice you will soon be able to get consistently good monitor
mixes. The MON 1& MON 2 signals are taken “pre fader” so that the channel fader has
no effect on the signal level sent to the monitor mixes.
The EFF 1 a n dEFF 2 controls send the channel signal to two more “side mixes” for use
in feeding effects devices such as the internal DSP unit or
outboard effects. The “Effects Send” signals are taken “post
fader”. This means that when the channel fader is reduced,
so is the effects signal. The EFF 2control feeds the internal
DSP system. By raising this control, you will send the channel’s signal to the internal Digital Reverb unit. However, the
DSP effect will not be heard until the DSP return control
(effects return RTN A) is raised (see the System Master
Section). The internal DSP return is automatically defeated
when an outboard processor is plugged in the RTN A j a c k .
13. PAN CONTROL - The P A N control allows you to set
the relative volume level of each channels send to the L / 3
and R / 4 master stereo outputs or to the Sub 1 and Sub 2
Sub Mixes, depending on the position of the L - R / 1 - 2s e l e c t o r
switch. Panning the channel all the way left will send the
signal only to the L / 3 stereo master or the SUB 1 m a s t e r ;
panning hard right will send signal only to the R / 4 s t e r e o
master or the SUB 2m a s t e r .

14. PEAK INDICATOR - Use the channel peak P K indicator to find the best setting
for the LINE/MIC gain control. The P K warning light will flash whenever a signal
exceeds a level of +12dBv anywhere within the channel. This light is used to warn
the operator whenever signal levels are so high that there is risk of distortion.
Whenever you see the P E A K LED flashing you should
reduce the setting of the LINE / MIC gain control, until
the LED just stops flashing. It is just as important to be
sure not to set the G A I N control too low. Setting the
channel gain too low will prevent you from achieving the
excellent signal-to-noise performance that the mixer is
capable of delivering. Note that the P E A K i n d i c a t o r
responds to overloading at the mic and line preamps, the
channel EQ, and the channel fader amp. Use this indi-
cator to set the GAIN controls on all of the channels as
your first step whenever setting up a mix. Careful use of
these controls will assure you of a distortion, free mix
with the lowest possible noise.
15. THE PFL CONTROL - The channel P F L (“pre fader
listen”) switch allows you to solo audition each channel or
group of channels to the control room monitors (or
phones) without affecting the main mix. The P F L s w i t c h
lets you to hear only the channel (or channels) selected,
even though you may be sending many signals through
the mixer to the main mix. This is an extremely useful
mixing feature that will help you to fine tune the EQ on
individual sources, even during a performance. You can
also combine solos. This means that you can depress
one or more P F L switches in order to listen to combina-
tions instruments to be sure their levels are good and
that they are blending well. Whenever you depress a
P F L switch the Peak LED will come on to indicate
that that channel is soloed. Also, whenever any chan-
nel or sub group is soloed, another master LED will light up in the System Master
Section to indicate that you are in a solo mode and that the normal control room feed
has been interrupted by the solo system.

16. CHANNEL ASSIGN SWITCH - This switch gives you the option of assigning a
channel to a sub mix or directly to the two-track output. Depressing this switch will
assign the channels output to the Sub Mixmaster faders, thus giving you the option
of grouping various channels as a side mix to the two-track.
17. THE MUTE SWITCH - When the channel M U T E switch is depressed the channels signal is totally removed from the system, including the monitor and effects side
mixes. The only control that is not muted is the P F L, thus allowing you to audition a
channel before folding it into the any of the active mixes.
18. THE CHANNEL FADER - The Channel Fader controls the volume of each
channel. It is accurately calibrated and adjusts the level of each channel as it is sent
to the sub mix, two-track, and effects mixes. A “normal” setting for the channel
faders would be between about -10 and +5 on the fader markings. This means that
usually you will be operating your channel faders relatively high compared to your
2 T R A C K faders. Keeping the channel faders high will help assure the most quiet
performance and best overall sound from your console.
