The exclamation point within the equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying this appliance. 6. Heat - Avoid placing this product too close to any high heat sources such as radiators. [. . . ] If the Beatkeeper is having trouble matching the beat to the flashing red Beat LED, or if you need to sync up Immediately, tap the Beat Assist button 2-8 times as you hear the beat, the same way you would tap your feet to the music. Pressing the Beat Assist Button more than once aligns the Beatkeeper to your taps. Notice that the Sync Lock LED automatically illuminates, signifying that the Beatkeeper is now locked in with the beat. Simply put, if the Beatkeeper isn't on track, or you're in a real hurry, you need to press a button twice instead of once. If the Beatkeeper is synced to the correct BPM but is aligned to the music's offbeat, tap the Beat Assist button with the beat of the music just once and you will have brought the Beatkeeper back in sync. Numark - The Proven Leader in DJ Technology ©1997 Numark Industries 11 http://www. numark. com DM 1835X 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. With the first selection synced (Sync Lock LED illuminated), sync up the right channel the same way you set up the left. As the second Sync Lock LED illuminates, a new dimension of DJing begins: V I S U A L MIXING. The bar graphs on the top of the Beatkeeper have now been activated and are updating automatically. NOTE: In order to perform a mix which is tracked by the Beatkeeper, both channels MUST be synced. This is indicated by the yellow Sync Lock LED being lit for both inputs. In order to create the perfect mix, your goal is to keep both bar graphs as close to centered (green or yellow) as possible. If they are exactly the same tempo, the green LED in the middle will light up. If one song is faster than the other, the bar graph will shift towards the faster song. If the Tempo Difference graph is not centered, adjust the speed of one of the inputs using the pitch control. For example, if the Tempo Difference graph has a red LED illuminated closer to the right channel of the Beatkeeper, the right channel is faster than the left channel, either slow down the right channel, or speed up the left channel. If the opposite is true, the Tempo Difference Graph has a red LED illuminated on the left channel, indicating the song on the left channel is faster than that the right channel, either slow down the left channel, or speed up the right channel. The second step involves the bottom graph, the Beat Offset Graph. If the beats of one input are earlier than beats of the other input, the Beat Offset Graph will shift toward the song with the earlier beats. To align the Beat Offset Graph when using CD Players, adjust the appropriate pitch bend. If you are using turntables, hold or apply pressure to the record/turntable and then release to "shift" the beat. If the Beat Offset graph is shifted toward the right channel either use the minus ("-") pitch bend for the right channel CD player (with vinyl, apply pressure to slow the turntable) or use the plus ("+") pitch bend for the left channel CD player (with vinyl push the turntable ahead). Intuitively, if either bar graph is shifted towards a channel, this indicates that the song on that channel is "ahead" of the other one. [. . . ] N O T E : Plug mono audio sources into both Left and Right inputs using a "Y" cable connector. 8. Use this to allow line level equipment to be plugged into your phono inputs giving you a total of 8 line input options. Your input signal is fed directly to the D M 1 8 3 5 X'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. [. . . ]
