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.  
0
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.
