PART NAME AND FUNCTIONS
34. BPM (beats per minute) display for PFL bus. Automatically displays the rhythmic speed of the
music assigned by (20) to the PFL bus. Please note that for accurate function, only one signal
shall be assigned to the PFL bus by means of switches (20) as otherwise no clear rhythmic
structure can be determined. A manual mode for BPM counting is available, see (36). The BPM
display will show " - - - . – " if the music signal has not enough sensible rhythmic content to
automatically determine a BPM value. In such case, wait unit the enough rhythmic content
becomes available, or use the manual tap mode as described in (36).
35. BPM (beats per minute) display for the main output signal. Function as described in (34), but for
he main output signal.
36. Tap button for the PFL-signal BPM counter. If the music signal has a rhythmic structure too
complex or not determined by percussive sounds, the automatic BPM counter may no be able to
derive a sensible result and will display " - - - . – " on (41). In this case, you can use the Tap
button to tap along the music; after 4 taps, the display (34) will show the average speed of your
tapping in BPM. The longer you tap, the more precise the result will get due to build-in averaging.
Once you stop tapping, the last result remains displayed on (34). If you wish to switch back to
automatic mode, just press the Tap button once. Whether in automatic or manual mode, the tap
buttons will flash with the speed of the displayed value in (34).
37. Tap button for main-signal BPM counter. Function as described in (36), but for the main output
signal.
38. Kill switches. Two sets of switches, one set assigned to the left side of the crossfader, the other set
assigned to the right side of the crossfader. Each set contains of three switches which allow to
infinitely attenuate ("kill") the respective low, mid or high frequency band signal content.
39. Effects on/off switch. Activates the effect which is chosen and defined by controls (40), (42), (43)
and (44). Once the effect is active, this switch is backlit.
40. Effects source selector. This rotary control allows to choose which stereo channel (or the main
output) are used as the source for the effects generator.
41. Effects PFL switch. Allows to pre-listen the generated effect without the effect being activated by
(39).
42. FX Mix control. Determines the level of the effect signal sent to the master output once (39) is
active.
43. FX scaler control. Any effect chosen by the effects selector (42) works on a time base that is
derived from main BPM value (35). This allows the effect to be time-aligned with the speed of the
main output signal. In some cases, it is desirable to however make the effects speed a fraction or
multiplier of the base speed. The FX scaler control allows to set the time base of the effect to
either 1/16, 1/8, 1/4, 1/2, 1, 2, 4 or 8 times the speed of the main BPM counter.
44. FX selector. This control allows to select the desired effect from 8 truly different and DJ-relevant
