IMPORTANT INFORMATION...
Please read this entire manual before
connecting the DM1190 to your system.
For optimum performance:
SYSTEM PRECAUTIONS
• Use appropriate cables throughout your
system: Quality shielded audio cables and
terminated shielded video cables, low-
capacitance preferred. Speaker cables must be
14-gauge minimum; 12- or 10-gauge is better.
• Always make sure that AC power is OFF
while making any connections.
• Do not use excessively long cables (i.e. over
50ft/14m) Be sure plugs and jacks are tightly
mated. Loose connections can cause hum, noise
or intermittents that could easily damage your
speakers.
• Reliability will be enhanced through the use of
banana connectors on the speaker wires.
Observe correct speaker wire polarity. If in
doubt, consult your Numark dealer or a qualified
technician.
• Never use spray cleaners on the slide
controls. Residues cause excessive dirt build-
up and this will void your warranty. In normal
use slide controls can last for many years. If
they malfunction (usually because of a dirty or
dusty environment) consult a professional
technician.
• Take care to connect only one cable at a time.
Pay attention to the color-coded, labelled Input
and Output jacks.
• ALWAYS remember: “TURN AMPS ON
LAST AND OFF FIRST”. Begin with master
faders or volume controls on minimum and the
amplifier gain/input control(s) down. Wait 8 to 10
seconds before turning up the volume. This
prevents transients which may cause severe
speaker damage.
• Never attempt to make any adjustments or
repairs other than those described in this
manual. Take the DM1190 to your dealer or to
an authorized Numark Service Center.
• Use restraint when operating controls. Try to
move them slowly. Rapid adjustments could
damage speakers due to amplifier clipping.
A NOTE ON CABLES:
• Avoid amplifier “clipping” at all costs: this
occurs when the red LEDs (usually on the front
panel of most professional power amplifiers)
start flashing. “Clipping” is when the power
amplifier is distorting and working beyond it’s
limits. Amplifier distortion is THE major cause of
speaker failure.
Make the input and output connections
with readily available low-capacitance
stereo cables. Quality cable makes a
big difference in audio fidelity and
punch. See your Numark dealer or an
electronics or audio specialist store if
you are not sure which cables to get.
• To prevent fire or shock hazard, do not expose
the unit to rain or moisture. Never place cans
of beer, soda, glasses of water or anything
wet on top of the mixer!

GUIDED TOUR OF FEATURES AND OPERATING
INSTRUCTIONS...
If the DM1190 is your first mixer, please read this
entire manual before you begin operation.
CROSSFADER SECTION
If you are an experienced DJ simply replace your old
mixer. The DM1190 can be rack-mounted or used
as a free-standing unit (five 19" rack unit spaces).
4. The Crossfader Assign knob to the left of the
crossfader lets you choose which input channel will
be heard when the crossfader is in the far left
position.
INSTALLATION AND OPERATION
5. The Replaceable Crossfader achieves clean
segues between the two selected input channels.
Study the Connections Diagram on page 13.
First, connect all stereo input sources. Next connect
your microphone(s) and monitor headphones. Make
sure all faders are at "zero" and the unit is off. Finally,
connect the stereo outputs to the power amplifier(s)
and/or audio sources. Plug the DM1190 into AC
power. Now you are ready to switch it on.
Off1 2 3 4
Off1 2 3 4
"Hard left" selects the channel set up of the Assign
Left knob. In this example it is Channel 1. "Hard
right" selects the channel set up on the Assign
Right knob. In this example it is Channel 4. With the
crossfader centered both assigned channels are
live. Use the crossfader for fast and seamless
segues from one selected channel to the other. To
turn off the crossfader simply turn both knobs all the
way to the left.
The DM1190 is divided into five functional blocks:
Input, Crossfader, DJ Mic, Master/Zone Output, and
Equalizer. It is important to learn how each of these
work.
CHANNEL INPUTS/CONTROLS SECTION
1. Channels 1, 2, 3 & 4 Input Toggle
Switches select which source will be live to that
channel based on what you have connected to the
rear panel input section.
Note: The crossfader is user replaceable in case of
failure. Simply unscrew the two large screws which
hold it in place, lift it out and disconnect it’s cable.
Re-attach the new crossfader and screw the
mounting plate back onto the unit - you’re back in
business!
2. The Input Faders are low-noise, low-
impedance, high-quality, smooth Alps™ faders.
These control individual source levels in the mix.
3. Channel Cue Assign. The Cue pushbuttons
are used to route channel audio to the Monitor
Section. The channel faders do not control the
Cue send volume.
6. The Crossfader Assign knob to the right of
the crossfader lets you choose which input channel
will be heard when the crossfader is in the far right
position.

DJ MIC SECTION
MASTER/BOOTH OUTPUT SECTION
The DM1190 has an extremely flexible DJ Mic
channel. The Talkover function reduces the level of
the music while leaving the DJ Mic at normal volume.
12. The Stereo Master Fader controls the overall
output level.
13. Stereo/Mono toggle adjusts the Master
7. Neutrik™ “Combo” connector allows connection
of either a 1/4” jack or an XLR jack. This is ideal for
connecting an XLR gooseneck directly into the mixer.
output for the operation selected.
14. The Zone Level controls speaker volume for a
remote zone or booth monitors. If you do not use
booth monitors the output can feed a tape deck,
another amplifier, another mixer or a satellite speaker
system. Note: This can also be used to supply line
level audio to a lighting controller or to lights that are
sound activated.
8. Treble and Bass Controls fine tune the tone of
your voice on both mics through the sound system.
The controls are detented for setting tone "flat". For
best results, use a dynamic cardioid microphone.
9. The DJ Mic 1 Fader controls the DJ Mic volume
for the Neutrik™ “Combo” connector.
CONTRACTOR'S NOTE: Booth Level provides
zone control in installations where there are two
separate rooms, or a bar and dance floor, for example.
Remote zone volume should be controlled from the
DM1190.
10. The Mic 2 Fader controls the Mic volume for the
1/4” connector on the rear of the mixer.
11.Mic Off/On/Talkover Switch.
Off turns off Mic 1
15. Stereo Auto Peak Hold Level Indicator.
This fast, accurate stereo meter tracks the output level.
The red LEDs for +3dB, +5dB and +8dB hold program
peaks for a second or two. With peak metering, it's OK
to be "in the red" as long as +5dB or +8dB aren't
constantly lit. Set the crossover, equalizer and power
amp inputs to avoid distortion at each step in the audio
chain. Proper attention to the peak meter results in the
punchiest possible sound without audible distortion.
O n turns on Mic 1
Talkover turns down the input level of your music
sources from Channels 1-4.
Talkover is very useful for making announcements
without adjusting any levels.
Try using this feature for audience participation
when you want the music to temporarily cease
and the audience to be heard - “YEAH!”

EQUALIZER SECTION
GENERAL EQ HINTS
16. 6-Band Stereo Graphic Equalizer (EQ).
EQ compensates for differences in source material
sound quality. In ultra-compact mobile systems this EQ
can be used to tailor the sound to the acoustical
requirements of the room. Center frequencies are
42Hz, 152Hz, 480Hz, 1.5kHz, 4.8kHz and 15.4kHz.
Faders have a center detent for an accurate "flat”
response.
Below is a typical "house" EQ curve. Notice how the
knobs above "0" balance out the knobs below. Start
with this setting if you've never used a graphic EQ
before:
• Boost the 42Hz band for deep bass tones and solid
kick drum sound. Use sparingly because this
dramatically increases demand on power amplifiers and
could drive them into “clipping” (see page 6).
• Cut slightly at 152Hz and more at 460Hz for extra
clarity. Note: Cutting is preferable to boosting.
• Boost 15kHz for a little "sizzle".
• As a general rule, less equalization is
better!
17. Equalizer On/Off. This controls whether your
final output will be routed through the EQ or not.
MONITOR SECTION
18. The Monitor section includes the Program Mix
control, the Headphone Volume control and the
Headphone Jack. Connect headphones with a
standard 1/4" stereo plug. The Cue audio is sent to
the headphone amp using the Cue Assign
Below is an example of a poor EQ curve because it cuts
the output volume down by 6-10dB. You have to
compensate by running the Master output higher:
Pushbutton and the Pgm Mix control. The
Program Mix controls the amount of program audio in
the headphones so that beats can be matched exactly
and segues are smooth when a song is cued.
0
Below is the worst sort of curve to use because you are
using EQ to add volume. With exaggerated boost you
can easily run your power amplifiers into “clipping” (see
page 6) and damage your speakers.
19. 12V BNC Connector allows a 12 volt
gooseneck lamp to be connected directly to the mixer.
This light is readily available from your Numark dealer.
20. Power Switch and Power-On LED.

REAR PANEL: INPUTS AND OUTPUTS
(Please refer to diagram on page 7)
7. Channels 1-5 Line Inputs are unbalanced RCA
jacks. The Line Input is selected with the toggle
switch on the front panel.
1. AC Cord. See safety precautions on page 3 for
proper treatment of the power cord.
You can connect stereo audio from HiFi VCRs, cassette
and reel-to-reel tape decks, DAT machines, CD players,
laser discs, tuners, even synthesizers or other mixing
consoles.
2. GND is the grounding lug for turntables 1, 2 and 3
(phono inputs on Channels 1, 2 and 3). Always use this
connection (your turntable cable should have a
grounding wire).
NOTE: Plug mono audio sources into both Left and
Right inputs using a “Y” cable connector.
3. The Stereo Main Outputs are low-impedance
RCA connectors controlled by the Master fader.
8. Line/Phono Input switch. Use this to allow line
level equipment to be plugged into your phono inputs
giving you a total of 8 line input options.
4. The Stereo Zone Outputs are low-impedance
unbalanced RCA jacks controlled by the Zone Level
control.
9. Phono Inputs on Channels 1, 2 and 3 use
unbalanced RCA jacks. Your input signal is fed directly
to the DM1190's high-quality RIAA phono pre-
amplifiers so use this position only for moving magnet
cartridges. Line level sources will overload the sensitive
phono pre-amps and will sound very bad, so always be
sure to toggle the line/phono switch over to line before
connection of line sources.
5. The Tape Outputs are low-impedance
unbalanced RCA jacks which output the program mix
and allow you to connect any recording device.
6. Mic 2 is the mic input for Channel 4.
