DM1635 GUIDED TOUR OF FEATURES AND OPERATING INSTRUCTIONS... If the D M 1 6 3 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 3 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 Send Out Jacks.
DM 1635 DJ MIC SECTION MASTER/BOOTH OUTPUT SECTION The D M 1 6 3 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.
DM1635 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.

SYNC LOCK BUTTONWhen an input is not yet set and scanning for the tempo tapping the Sync Lock button once will lock in the music as long as there is a BPM number displayed for the input. When an input is locked in tapping the Sync Lock button tells the Beatkeeper to start scanning for a new tempo again.
DM1635 BEATKEEPER OPERATION Channel Selection When your mixer is first turned on the channels selected will be 1 & 2 respectively. If you wish to track the beat of another channel, tap on the channel select button until the desired input is reached. NOTE: The Beatkeeper will track the source that is selected with the channel toggle switch. After syncing an audio input, try speeding up and slowing down the music.
DM 1635 2 Channel Mixing After you feel comfortable syncing up the Beatkeeper, you're ready to mix. Mixing with the Beatkeeper has three parts: syncing to the music (which you've done), aligning the tempos, and aligning the beats. Once these three things are done, you will have a perfect mix. No more guessing, tapping, or embarrassing fades. Choose another music selection and start it on your right channel. Sync up the first song as described in the last section.
DM1635 Multiple Channel Mixing Prepping For A Mix One exciting feature of your Beatkeeper built into your mixer is the option to visually beat mix more than 2 sources at the same time. Once you have synced a channel of the Beatkeeper the unit will continue to track it even if you should decide to change channels. Up to all four channels can be in sync simultaneously. By selecting different channels you can cross-compare the mix of any 2 channels instantly.
DM 1635 BEATKEEPER TROUBLESHOOTING T1 The BPM goes way off when using the search button on my high tech CD mixer. Some high tech CD mixers have a cueing feature which allows you to cue precisely to an exact spot in the music so you can slam mix. The only problem is that this mode repeats the first beat of the music at a rate which is unrelated to the actual BPM of the music. As a result, the BPM goes off track.
DM1635 T8 I hit the Sync Lock button, but the flashing red beat LED doesn't seem to follow the beat. This means you hit the Sync Lock button before the red beat LED actually started tracking the tempo. You can easily fix this by tapping the Beat Assist buttons as many times as necessary to resync to the beat of the music. T9 The beat tracking suddenly gets off track. This may happen if the music has several beats missing, or the rhythm suddenly becomes extremely complex or variable.
