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. 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.

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 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. 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 green LED 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. 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. Either the tempo is faster (top graph), or the beats come sooner (bottom graph).

When both bar graphs are in the green you are ready to perform your mix!

Don’t forget you can always resync to the beat, if it ever shifts off, by tapping the Beat Assist button.

If the beats start to drift, you'll be able to easily adjust the music before your audience can hear it. No other beat counter or automatic mixer can give you the power to make a more accurate mix!

NOTE: The Beat Offset bar graph either indicates beat- to-beat offset, or beat-to-halfbeat offset, whichever is closer. This allows the DJ the option of mixing on the beat or on the half beat.
