DM1685 GUIDED TOUR OF FEATURES AND OPERATING INSTRUCTIONS... If the D M 1 6 8 5 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 1 6 8 5 can be rack-mounted or used as a free-standing unit (five 19" rack unit spaces). 4. Effect Send (Channels 1-4). Depress these buttons when you want the signal from any input channel to be routed to the Sampler and the Send Out Jacks on the rear panel.
DM 1685 DJ MIC SECTION MASTER/BOOTH OUTPUT SECTION The D M 1 6 8 5 has an extremely flexible DJ Mic channel. The Talkover function reduces the level of the music while leaving the DJ Mic at normal volume. 13. The Stereo Master Fader controls the overall output level. 8. Neutrik™ “Combo” connector allows connection of either a 1/4” jack or an XLR jack. This is ideal for connecting an XLR gooseneck directly into the mixer. 9.
DM1685 EQUALIZER SECTION 17. 6-Band Stereo Graphic Equalizer ( E Q ) . 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.
DM 1685 DIGITAL SAMPLER SECTION 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. 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: • R e p e a t sets the unit to play back a sample and automatically repeat (loop) when it gets to the end of the sample.
DM1685 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. 28. Effect Level Mix fader.
