DM900EX

GUIDED TOUR OF FEATURES AND OPERATING INSTRUCTIONS...

If the D M 9 0 0 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 D M 9 0 0 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 D M 9 0 0 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.

N o t e : 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 C u e selector is used to route channel audio to the Monitor Section. The channel faders do not control the C u e 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 C u e 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.
