6 PRO MIXER DJX900USB User Manual 2. Microphone Channel (7) The MIC IN connector is the balanced XLR input for your dynamic microphone. (8) Set the volume of the microphone signal with the GAIN control in the MIC section. (9) There is a 3-band equalizer (HI, MID and LOW, no kill characteristic) in the microphone section. This allows you to fine-tune your voice to adapt perfectly to your sound. (10) Activate the microphone channel using the MIC ON switch. The channel is active when the corresponding LED is lit. (11) The DJX900USB is equipped with a talkover function, which works very simply: if you speak into the microphone while a track is running, the volume of the music is automatically reduced, so that your voice is always "in front". The TALK control allows you to determine how much the music volume is lowered (max. -24 dB). This function can come in handy when your own voice needs to be prominently heard, as in when making an announcement etc. 3. Monitor Section The MONITOR signal is your headphones signal, allowing you to listen to music without affecting the MASTER output signal. (12) When the MODE switch is in the "Split" position, channel PFL is located on the left side of the headphones, while the MASTER signal is on the right side. In this case, the MIX control (see below) serves no function. While in "Stereo" mode, you can use the MIX control to alternate between MASTER signal and PFL. (13) When in "Stereo" mode, the MIX control lets you determine which signal can be heard via the headphones. When the control is turned to its left-most position (CUE), you hear the PFL signal only; when the control is turned to its right-most position, you hear the MASTER signal only. Alternating the MIX control between the two end positions lets you determine the relative ratio between the two signals in your headphones. (14) The LEVEL control determines the volume of the headphones signal. (15) Connect your headphones using the PHONES OUT stereo connector. Your headphones should have a minimum impedance of 32 Ohms. (16) To select the PFL signal for the headphones, use the MONITOR CUE keys (CH-1 to CH-4, MASTER, FX). You can also select multiple signal sources and listen to them simultaneously. LEDs on corresponding keys are lit when a channel is routed to the headphones. 4. Master Section (17) The LEVEL METER displays the level of the MASTER signal. (18) The MASTER fader allows you to adjust the output volume at the MASTER output (see (44)). (19) The MASTER BALANCE control for the MASTER output is for setting the stereo image. (20) The BOOTH LEVEL control adjusts the output level of the BOOTH output (see (45)). 5. Crossfader Section (21) ASSIGN A and ASSIGN B selectors let you determine which input signals are routed to CROSSFADER sides A and B. You can also alternate between these two signals by using the CROSSFADER (see below). (22) The CROSSFADER is used to fade between the channels you have selected (see (21)). (23) The TIME OFFSET LED indicates the synchronization of tracks (see chapter 2.7). (24) The TEMPO DIFFERENCE LED displays tempo differences between the tracks (see chapter 2.7). (25) A 3-band kill switch is available for use with both the left and the right side of the crossfader (KILL A and KILL B respectively). Kill switches are used to lower three separate frequency ranges (LOW, MID and HIGH) up to -32 dB. When using the kill switch, the equalizer of ordinary DJ mixers usually loses its functionality. Not the case with the DJX900USB: the EQs can be used to achieve an even more pronounced lowering of a particular frequency range. (26) The CF CURVE control lets you alter the control characteristic of the crossfader between a smooth blend to a steep cut in an infinite number of steps. When set to smooth blend (far left), one source fades in gradually while the other fades out at the same rate. When set to steep cut (far right), the sources quickly fade in and out at the far edges of the crossfader's range. For example, with the CF CURVE knob set to the far right and the crossfader set to the far left, only source A is audible. As the crossfader moves to the right, source B quickly fades to full volume. Both sources remain at full volume for most of the middle range until source A quickly fades out just before the crossfader reaches its far right position. 6. XPQ 3D Surround Effect The XPQ 3D surround function is a built-in effect that puts the finishing touch to your music and turns every gig into a real experience. The widening of the stereo base makes for a livelier, more transparent sound. You can determine the intensity of the effect by using the SURROUND control (27), while the XPQ ON switch (28) turns the XPQ effect on (the respective LED is lit). 7. Auto BPM Counter The integrated auto BPM counter is an extremely useful feature. It ensures smooth transition from one track to the next, taking a lot of the guesswork out. It can calculate the various tempos of tracks in bpm (beats per minute). Both BPM counter sections are identical and both show the BPM value of the two signals routed to the crossfader. The LEDs located above the DISPLAYs 1 - 4 (29) indicate which of the four input channels are routed to the respective BPM counter. The tempo of the track assigned by using the ASSIGN A or ASSIGN B keys is shown in the respective Display (30). Several tempo changes in one track would produce a constant display of various BPM values and thus lead to unnecessary confusion. That's why the beat counter sections each have a SYNC LOCK button (31) that can be used during the song to limit the range of possible tempo values. This makes sense if the counter has already calculated a realistic value. You can do the same thing manually with the BEAT ASSIST button (32). Pushing this button at least three times in sync with the song's tempo results in the calculated tempo appearing in the DISPLAY. The Beat Assist and SYNC LOCK buttons are each equipped with a LED.
