engages directly proportionally to the fader’s incremental movement. When set to logarithmic, the fader’s movement yields higher volume increases as the fader moves farther along its range of motion.

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).

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. When you have limited the tempo of the tracks on both channels with the SYNC LOCK or BEAT ASSIST buttons, the difference in tempo from both channels is illustrated in the form of a nine-character message on the TEMPO DIFFERENCE-LED [24]. The extent of the difference in tempo is indicated by a corresponding swing to the right (signal A is slower) or to the left (signal B is slower). When the middle LED lights up, the tempi are the same. The TIME OFFSET LED [23] below that displays the signal A and B synchronisation. Should the middle LED light up, the tracks are synchronised. Should the display move to the left or right, the channels are not synchronised. The TEMPO DIFFERENCE and TIME OFFSET displays are only active if the tempi of both channels have been fixed in one of the ways described.

◊When no signal is present (or when the signal level is too low), the BPM display shows only dashes. When the signal is present but can not be identified, the display shows

160 BPM and then shows the said dashes. The beat counter then attempts to get another readout. Therefore, “160” BPM is no usable value; rather, it is simply an error message when the signal can not be analyzed.

To exit the SYNC LOCK or BEAT ASSIST modes, simply push the SYNC LOCK button once more on both channels.
