[. . . ] 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. 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: VISUAL 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. ©1998 Numark - The Leader in DJ Technology Industries 11 http://www. numark. com DM1200/DM1235/DM1285 In order to create the perfect mix, your goal is to keep both bar graphs as close to centered (Greenor Yellow) as possible. First, align the top graph, the Tempo Difference Graph. This graph indicates how close the two BPMs are to each other. If they are exactly the same tempo, the GreenLED 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 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. This graph indicates how close the individual beats are. Both BPMs may be the same but the beats may not be in sync. This is often described as the "ping-pong" effect. If the beats are matched, the GreenLED in the middle lights up. 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. [. . . ] 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. 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. [. . . ]
