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

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.
