DIGITAL SAMPLING Guidelines for sampling • Connections: If you are using a microphone, make sure that it is connected to the MIC jack and not the LINE IN jack. Connecting a microphone to LINE IN will not damage the DJX; however, it will be impossible to get a recordable signal (the microphone level is too low). • Avoiding feedback: To avoid feedback, make sure that the microphone is pointed away from the speakers and is placed relatively distant from them. • Sample start points: Always record your sample as close to the intended start point as possible, since this cannot be changed later. For example, if you are sampling a four-beat rhythmic phrase from a CD, cue up the selection (and pause it) so that when you hit PLAY, the phrase plays from the top of the measure. The trigger level setting can help with this as well, since it effectively puts sample recording on standby until a strong enough signal (e.g., the first beat of phrase) arrives to start recording. (See "Trigger Level" below.) • Proper levels: In general, you'll want to record the signal as "hot" as possible - loud enough to record and be heard properly, but soft enough to avoid clipping and distortion. The level meter is a total of 8 bars in height; try to keep the input level at a maximum of 7 bars. Level meter at "7." Signal peaks that occasionally push the meter to "8" may still result in a clean recording. However, you should avoid letting the signal pin the meter to "8" (unless you want a deliberately distorted recording). Also, let your ears be the judge - if you hear distortion in the signal, bring the input level down. • Simultaneous MIC and LINE IN use: Both the MIC and LINE IN inputs can be used simultaneously for sampling. The key to mixing your voice with a line input is in having an output control on the line source (e.g., CD player) - in that way you can adjust the balance of the line source with your vocals, then use the INPUT LEVEL knob on the DJX to control the overall level. Trigger Level Actually, the DJX does not start sampling immediately when the START/STOP button is pressed (in step #5). Once the START/STOP button is pressed, the DJX waits for a signal of a suitable level (set by the trigger level). When it hears such a signal, it starts sampling. To set the trigger level, use the +/- buttons of the numeric keypad. Press the + button to raise the trigger level, and press the - button to lower it. 7 BWD 8 rest 0 velocity 9 3 FWD Trigger level meter The higher the trigger level, the louder the signal must be to start (trigger) sampling. You can instantly restore the default trigger level setting by pressing both +/- buttons simultaneously. 71
