The Stereo Main Outputs are low-impedance RCA connectors controlled by the Master fader. 3. The Tape Outputs are low-impedance unbalanced RCA jacks which output the program mix and allow you to connect any recording device. 4. The Stereo Zone Outputs are low-impedance unbalanced RCA jacks controlled by the Zone Level controls. 5. The Send can be attached to an external effects processor such as a sampler. 6. Mic is the mic input for the Mic Channel and Channel 4. 7. Channels 1-5 Line Inputs are unbalanced RCA jacks. The Line Input is selected with the toggle switch on the front panel. 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. NOTE: Plug mono audio sources into both Left and Right inputs using a “Y” cable connector. 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. 9. Phono Inputs on Channels 1, 2 and 3 use unbalanced RCA jacks. Your input signal is fed directly to the DM1820X's high-quality RIAA phono preamplifiers so use this position only for moving magnet cartridges. Line level sources will overload the sensitive phono preamps and will sound very bad, so always be sure to toggle the line/phono switch over to line before connection of line sources. 10. AC Cord. See safety precautions on page 3 for proper treatment of the power cord. 11. Voltage Selector. Set this for the appropriate voltage in your area 12. 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).

All connections should be made before the unit is turned on. Always remember “Turn Amps on last and off first!” 2. Use appropriate cables throughout your system: quality shielded audio cables, low capacitance preferred. Speaker cable must be 14-gauge minimum; 12- or 10-gauge is better. 3. Connect your music sources on the rear of the unit. Up to 3 phono and 8 line sources (CD players, cassette decks, tuners, etc.) can be connected. When connecting to an input with a phono/line option switch remember to set the switch accordingly. 4. Connect the ground wire from your turntables (and any other sources that come with a ground) to the ground post on the rear panel. This will eliminate most common hum and feedback problems. 5. Connect your DJ mic on the front left side of the unit (23) or on the back of the unit at Mic 1. Connect your second mic at Mic 2 on the back of the unit. 6. Connect your headphones on the front right side of the unit at (14). 7. The OUTPUT MASTER jacks on the rear of the unit are for connecting to the amplifier. Use the balanced outputs if possible. Make sure you correctly attach the right and left cables to avoid phasing problems. Numark - The Proven Leader in DJ Technology ©1997 Numark Industries 12 DM1820X DM1820X CONNECTION DIAGRAM...
