Remote zone volume should be controlled from the DM1190. 15. Stereo Auto Peak Hold Level Indicator. This fast, accurate stereo meter tracks the output level. The red LEDs for +3dB, +5dB and +8dB hold program peaks for a second or two. With peak metering, it's OK to be "in the red" as long as +5dB or +8dB aren't constantly lit. Set the crossover, equalizer and power amp inputs to avoid distortion at each step in the audio chain. Proper attention to the peak meter results in the punchiest possible sound without audible distortion.

EQ compensates for differences in source material sound quality. In ultra-compact mobile systems this EQ can be used to tailor the sound to the acoustical requirements of the room. Center frequencies are 42Hz, 152Hz, 480Hz, 1.5kHz, 4.8kHz and 15.4kHz. Faders have a center detent for an accurate "flat” response. Below is a typical "house" EQ curve. Notice how the knobs above "0" balance out the knobs below. Start with this setting if you've never used a graphic EQ before: 0 Below is an example of a poor EQ curve because it cuts the output volume down by 6-10dB. You have to compensate by running the Master output higher: 0 Below is the worst sort of curve to use because you are using EQ to add volume. With exaggerated boost you can easily run your power amplifiers into “clipping” (see page 6) and damage your speakers. 0 GENERAL EQ HINTS • Boost the 42Hz band for deep bass tones and solid kick drum sound. Use sparingly because this dramatically increases demand on power amplifiers and could drive them into “clipping” (see page 6). • Cut slightly at 152Hz and more at 460Hz for extra clarity. Note: Cutting is preferable to boosting. • Boost 15kHz for a little "sizzle". • As a general rule, less equalization is better! 17. Equalizer On/Off. This controls whether your final output will be routed through the EQ or not. MONITOR SECTION 18. The Monitor section includes the Program Mix control, the Headphone Volume control and the Headphone Jack. Connect headphones with a standard 1/4" stereo plug. The Cue audio is sent to the headphone amp using the Cue Assign Pushbutton and the Pgm Mix control. The Program Mix controls the amount of program audio in the headphones so that beats can be matched exactly and segues are smooth when a song is cued. 19. 12V BNC Connector allows a 12 volt gooseneck lamp to be connected directly to the mixer. This light is readily available from your Numark dealer. 20. Power Switch and Power-On LED. Numark - The Proven Leader in DJ Technology ©1997 Numark Industries 10 DM1190 REAR PANEL: INPUTS AND OUTPUTS (Please refer to diagram on page 7) 1. AC Cord. See safety precautions on page 3 for proper treatment of the power cord. 2. 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). 3. The Stereo Main Outputs are low-impedance RCA connectors controlled by the Master fader. 4. The Stereo Zone Outputs are low-impedance unbalanced RCA jacks controlled by the Zone Level control. 5. The Tape Outputs are low-impedance unbalanced RCA jacks which output the program mix and allow you to connect any recording device. 6. Mic 2 is the mic input for 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 DM1190's high-quality RIAA phono preamplifiers so use this position only for moving magnet cartridges. Line level sources will overload the sensitive phono pre-amps and will sound very bad, so always be sure to toggle the line/phono switch over to line before connection of line sources.
