DM900EX
GUIDED TOUR OF FEATURES AND OPERATING INSTRUCTIONS...
If the DM900 is your first mixer, please read this entire
manual before you begin operation.
If you are an experienced DJ, simply replace your old
mixer. The DM900 can be rack-mounted or used as a
free-standing unit (four 6" rack unit spaces).
INSTALLATION AND OPERATION
Study the Connections Diagram on page 13. First,
connect all stereo input sources. Next connect your
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
DM900 into it’s power supply and plug this into power.
Now you are ready to switch it on.
1. Power Switch and Power-On LED.
The DM900 is divided into five functional blocks:
Input, Crossfader, Monitoring, and Master Output. It is
important to learn how each of these work.
CHANNEL INPUTS SECTION
2. Channels 1 & 2 Input Toggle Switches select
which source will be live to that channel based on what
you have connected to the rear panel input section.
3. The Input Faders are low-noise, low-impedance,
high-quality, smooth Alps™ faders. These control
individual source levels in the mix.
CROSSFADER SECTION
4. The Replaceable Crossfader achieves clean
segues between the two input channels.
"Hard left" selects Channel 1. "Hard right" selects
Channel 2. With the crossfader centered both assigned
channels are live. Use the crossfader for fast and
seamless segues from one selected channel to the
other.
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!
MONITOR SECTION
5. Channel Cue Assign. The Cue selector is used
to route channel audio to the Monitor Section. The
channel faders do not control the Cue volume.
6. Headphone Volume controls the output level to
the Headphone Jack located on the front panel of
the mixer. Connect headphones with a standard 1/4"
stereo plug. The Cue audio is sent to the headphone
amp using the Cue Assign Selector.
MASTER OUTPUT SECTION
7. The Stereo Master Fader controls the Master
output level.
8. The LED METER indicates the Master output level.
