MATCHING TEMPOS & BEATS
You can match your tracks' tempos by monitoring the music of both PLAYER 1 and PLAYER 2 by ear and adjusting the pitch.
If the tempo of the music on one CD player is slower the other, move the slider to the ( + ) side to match the tempo. If it is
faster, move the pitch slider to the ( - ) side. The following instructions give an example of how to do this.
1. Press PLAY/PAUSE to start PLAYER 1. PLAYER 1 will begin playback.
2. Press PLAY/PAUSE to start PLAYER 2. Now, both decks should be playing.
3. Listen to PLAYER 2 in your headphones. If its tempo (in the headphones) is faster
than that of PLAYER 1, slow down PLAYER 2's tempo using the pitch control.
If PLAYER 2' tempo (in the headphones) is faster than that of PLAYER 1, speed up
PLAYER 2's tempo using the pitch control.
BEAT MATCHING USING PITCH BEND
Once you have matched the tracks' tempos, you may still need to match their downbeats to create a smooth mix. You can do
this by temporarily changing the pitch with the PITCH BEND/JOG WHEEL.
After matching the tempos adjust the pitch temporarily as follows:
When a track is ahead, rotate the jog wheel counterclockwise to temporarily slow it down.
When a track is behind, rotate the jog wheel clockwise to temporarily speed it up.
The pitch will change while the PITCH BEND/JOG WHEEL is rotated. (The faster you rotate the wheel the
greater the shift in pitch.) Release the wheel when the downbeats are aligned the way you want them and the
track will return to its original tempo/pitch.
EXAMPLE OF MIXING USING BOTH PLAYERS OF YOUR CD PLAYER
While playing a disc on PLAYER 1, load a disc into PLAYER 2 and select your next track, match its pitch to the track playing on
PLAYER1 and when you are ready use the crossfader on your mixer to fade from PLAYER 1 to PLAYER 2.
