AUTO BPM Counter 

The integrated auto BPM counter is an extremely useful feature. It ensures smooth transition from 

one track to the next. It can calculate the tempos of various tracks in BPM (beats per minute). Both 

BPM counter sections are identical and both show the BPM value of the two stereo channels routed to 

the crossfader. 

 

The tempo of the track assigned by using the ASSIGN AorASSIGN B keys is shown in the respective 

DISPLAY (31). Several tempo changes in one track would produce a constant display of various 

BPM values and thus lead to unnecessary confusion. That s why each beat counter section has a 

SYNCLOCK button 32 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 

manually with the BEATASSIST button (33). Push this button at least three times in sync with the song 

s tempo, and the tempo you tapped appears in the DISPLAY. The BEAT ASSIST and SYNC LOCK 

buttons are each equipped with a LED. 

 

To exit SYNC LOCK or BEAT ASSIST mode, simply press the SYNC LOCK key in both channels 

once again. 

 

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 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. 

2.9. 

Connections 

(34)These are the LINE and CD inputs respectively, used for connecting tape decks, CD or MD 

players etc. Unlike other channels, channels 4 and 5 feature two line inputs. 

 

(35)The PHONO inputs for channels 1 through 3 are intended for connecting turntables. Channels 

1 through 3 can be switched over to line level (see (36)). 

 

(36)Using the PHONO/ LINE switches, you can change the input sensitivity of the PHONO inputs 

on channels 1 through to line level (switch pressed). This way, you can even connect a tape 

deck or a CD player to the PHONO inputs. 

 

IMPORTANT : Always pay attention to the correct position of the PHONO/LINE switch when 

connecting a line level signal to a phono input. The switch must be in its pressed 

position (LINE)! Otherwise,overdriving may lead to permanent damage 

to the phono input.
