IMPORTANT INFORMATION...  
Please read this entire manual before connecting the DM1885X 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.  
• 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.  
• 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.  
• 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.  
• Use restraint when operating controls. Try to  
move them slowly. Rapid adjustments could  
damage speakers due to amplifier clipping.  
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.  
• Never attempt to make any adjustments or  
repairs other than those described in this  
manual. Take the DM1885X to your dealer or to  
an authorized Numark Service Center.  
A NOTE ON CABLES:  
Make the input and output connections  
with readily available low-capacitance  
stereo cables. Quality cable makes a  
big difference in audio fidelity and  
punch. Use balanced connections  
whenever possible. 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!

1. Channel Input Gain/Trim/Attenuation Controls.  
These control the sensitivity of the inputs for Channels 1-4.  
Use these whenever a particular source causes overload of  
the preamp inputs. Attenuation range is 0dB to -20dB. Use  
these with the PFL (pre-fader listen) monitor when cueing.  
5. DJ Mic Talkover Switchhen engaged this mutes your  
music sources from channels 1-4. Releasing it brings you  
immediately back to full source level. It is very useful for  
announcements.  
6. Channels 1 - 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.  
2. Treble, Middle and Bass Controls fine tune the tone  
of your music through the sound system. Note that these  
are also available on the DJ Mic.  
7.The Input Faders are low-noise, low-impedance, high-  
quality, smooth faders. These control individual source  
levels in the mix.  
3.Use the Pan Control to maximize the Left or Right side of  
your Source.  
4. Send button will send the individual channel signal to the  
onboard sampler and the send jack on the rear panel. This is  
used to route to an external effects unit. The signal comes  
back in from the effects unit through any line input channel  
you select and is then sent out to your amplifier through the  
Master Output jacks on the rear panel.  
8. Channel Cue Assign/PFL pushbuttons are used to  
route channel audio to the Monitor Section. The channel  
input faders do not control the Cue volume. When the Cue  
button is pushed you get Pre Fader Listen(PFL). In addition,  
when these buttons are depressed the third row of the LED  
meter (20) will display the signal level of that channel on a  
PFL basis. The level can be adjusted by using the Gain  
control (1).

is always active even when the crossfader is not. Try that for  
a neat effect, or mix one channel’s treble with another  
channel’s bass (by cutting the mid and bass on the first  
channel and the treble and mid on the other channel.)  
10. Crossfader/Kill Assign Switches lets you choose  
which input channel will be heard when the Crossfader is  
moved to the left or right and affected by the Kill function.  
16. Master Level. This controls overall output level. Note that  
you can select (18) whether you want stereo or mono.  
11.The replaceable Crossfader achieves clean segues  
between two selected input channels.  
17. The Zone Levels control speaker volume for other outputs  
such as control booth monitors, a tape deck, another  
amplifier, a sub-woofer, another mixer or a satellite speaker  
system. Note that you can select (18) whether you want  
stereo or mono.

In this example, Channel 1 is selected on the Left and  
Channel 3 is selected on the Right. With the Crossfader  
centered both assigned channels are live. Use the  
Crossfader for fast and seamless segues from one channel  
to the next.  
CONTRACTOR'S NOTE: Zone Level provides zone  
control in installations where there are two separate rooms  
(eg: a bar and a dance floor). The “Zone” volume should be  
controlled from the mixer not from the amplifier.  
18. The Stereo/Mono Toggle Switches allow you to select  
Note: the crossfader is user replaceable. Simply unscrew  
the two large screws which hold it in place, lift it out, and  
disconnect its cable. Reattach the new crossfader and  
screw it back onto the unit - you’re back in business!  
REPLACEMENT CROSSFADERS can be purchased from  
your local Numark Dealer, or by calling Numark Industries.  
either stereo or mono output.  
19. Stereo Auto Peak Hold Level Meter. The red LEDs for  
+3, +5 and +8dB hold program peaks for an instant.  
With peak metering, it's OK to be "in the red" as long as +5 or  
+8dB isn't constantly lit. Set crossover, equalizer and power  
amplifier inputs to avoid distortion at each step in the audio  
chain. Proper attention to the peak meters results in the  
punchiest possible sound without audible distortion.  
12.The Cue Crossfader controls what signal is being  
monitored through your headphones. Move the slide  
control to the left and you will hear your source music from  
the channel(s) selected with the cue/PFL switch. Move the  
control to the right and you will hear your program mix, or  
output. The slide control allows fast and frequent  
headphone monitoring.  
20. PFL Meter. When the Cue/PFL switches are depressed  
this meter tracks pre-fader listen (PFL) signal for the channel  
selected instead of the mixer’s output level.

DIGITAL SAMPLER SECTION  
TO RECORD A SAMPLE  
The Sampler uses dynamic RAM with a 16-bit  
microprocessor controller. The same digital signal  
processing components used in professional audio  
equipment deliver CD-quality samples.  
a - Press the Write button once to go into stand by  
mode. The red LED will go on.  
b - Select the bank (or multiple banks) into which you want to  
record. Any bank can be selected. Each bank contains 3  
seconds of recording time. If you want to record a longer  
sample select multiple banks (they must be adjoining). To  
playback a multi-bank sample you must reselect the same  
banks later. Note: To overwrite an existing sample,  
select that bank instead of an empty bank. Changing bank  
selection at this point in time is possible and will not destroy  
any previously recorded samples.  
25. The Mode Pushbuttons switch from effect to  
effect. The accompanying LEDs illuminate to show you  
which specific mode you are in at any time.  
Modes are:  
Repeat sets the unit to play back a sample and  
automatically repeat (loop) when it gets to the end of e - Hit the Start-Stop button to begin recording. It's red LED

will light.  
Single sets the unit to play back a sample once.  
f - Hit Start-Stop a second time to stop the sampling, or  
allow the memory banks to fill up, at which time sampling will  
stop automatically. Once your writing is complete the  
sampler will automatically switch to Single playback mode  
and light the Single LED. The sampler is now ready for  
playback.  
Edit sets the unit to sample edit. This activates the  
Intro and Outro editing controls as described in  
#26. Edit can be used at the same time as Single  
and Repeat so that editing of the sample can be  
done while your program output is playing on the  
dance floor.  
26. Intro and Outro editing controls are used when Edit  
mode is selected to fine tune the beginning (Intro) or  
ending (Outro) of your samples. These "trim" the  
Write sets the unit to sampler record ready.  
Depress the appropriate send button for the channel  
you wish to record. Selecting a bank to record to and  
hit the Start/Stop button (#30) to begin recording  
(it is safer to actually choose your bank before going  
to write mode so that you don't accidentally wipe out  
an existing sample). The LED will stay lit while you are  
in Write mode. After you are done writing your  
sample you should select a play mode (either Single  
or Loop) and listen to your sample - note that you  
must do this manually by hitting the correct Mode  
Pushbutton.  
unwanted sound while in Single or Repeat playback  
modes. Turn the controls inward to trim more - return them  
to their full outside position to return to your full sample.  
Once trimmed turn Edit off to lock-in your settings, now  
every time you select the sample it will be the perfect  
length. Note: Trimmed samples are not erased - they can  
be heard again by going back into Edit and undoing the  
trim. This powerful new feature allows you to start a sample  
early or end it late and still trim it to the perfect length  
without having to re-record. Since these controls can be  
active while the sample is "live", you can even fine tune  
samples on the fly. A way of efficiently trimming samples is  
by engaging the Stutter button and repeatedly hitting the  
Start-Stop button as you adjust the Intro knob.

27. The Speed Control plays samples faster or slower  
resulting in a pitch shift of the sample. In the center  
position, the sample is played at recorded speed. Moving  
the knob to the left will slow down playback by up to 50%;  
moving the knob to the right will speed up the playback by  
up to 200%. Positions near the center provide fine  
changes in playback speed. Positions further from the  
center detent provide more drastic changes in playback  
speed.  
• In Single or Repeat play with Trigger you are  
ready to "stab" samples. With the Trigger Out, the  
sample plays all the way through before you can play it  
again. With it In, you can stab or stutter a sample.  
When you shout "Rock it - rock the house!" and  
sample it, it can be played back as -  
R-R-R-R-R-R-R-Rock --  
Rock-Rock-Rock it - Rock it Rock it -  
Rock - - Rock it - rock the house!  
28. Effect Level Mix fader. This precisely sets the audible  
level of the sample in the mix.  
by simply "drumming" with your fingers.  
29. Memory Bank Select Pushbuttons A-D. Four  
banks are available for storing samples. To record a bank  
go to Write and then hit the bank button. You can record  
into any combination of banks by pressing multiple bank  
buttons.  
31. The Stutter Pushbutton lets you choose  
between two playback styles, Trigger and Non-  
Trigger, when in Single or Repeat modes.  
• When the Stutter is Out and the sampler is set to  
Single or Repeat mode, each time you tap the  
Start-Stop button the sample starts to play. The  
next tap stops sample playback. The next time play  
starts, the sample re-starts at the beginning.  
After sampling, you can either select the next bank and  
record it (remember Write is still on, just select the bank  
and hit Start/Stop) or you can manually select a playback  
mode.  
• When the Stutter is In and the sampler is set to  
Single or Repeat mode, each time you tap the Start-  
Stop button the sample re-triggers.  
You can play any combination of the Memory Banks from  
left to right (that is, Memory Bank B will always play before  
Memory Bank D - but you can play ABCD; BC; BD: ACD;  
only C; only D; etc.).  
ABOUT STUTTERING  
Expensive studio rack-mount samplers and sampling  
keyboards can re-trigger or stutter. This means  
"beginning at the start of the sample each time a key  
is pressed or a drum pad is struck".  
30. The large Start-Stop button controls sample recording  
and sample playback. The small red Effects Indicator LED  
glows when the sampler is "on". Here are the functions:  
Tap the button when in sampler Write mode to begin  
sampling (the LED will light). Tapping it again ends the  
sample and the LED goes out. (unless the sampler has run  
out of memory and shuts off automatically - Once the  
Effects Indicator LED goes out, the Write LED goes  
out and the Single LED turns on.  
Re-triggering creates the stuttering "rap" effect. The  
DM1685/1885 includes a manual stuttering  
feature. How fast can you tap? Try using two fingers  
for increased speed.  
32. Monitor Pushbutton. To hear the sample or  
effect in the headphones, press this button.  
Program Mix still works and you will be able to hear  
any other input channels with the Cue buttons  
activated.  
• In single or repeat play without Trigger, tap the button  
to play the sample and tap it again to stop the playback.  
Every time you play the sample, the music starts from the  
beginning of the sample.
