ThePOWER LED (14) will be off. This unit comes supplied with a 15 voltAC adaptor. Plug the adaptor into the rear panel power jack

3、. Then plugthe adaptor into a proper power source.2. Use the 4 stereo PHONO/LINE (2, 5, 8, 11) inputs on the rear panel toconnect to the output of your sources. The PH1/LN1 (12) switchenables you to set the CHANNEL 1 (11) input sensitivity to Phono orLine. The PH2/LN2 (9) switch enables you to set t

4、he CHANNEL 2 (8)input sensitivity to Phono or Line. The PH3/LN3 (6) switch enables youto set the CHANNEL 3 (5) input sensitivity to Phono or Line. The PH4/LN4 (3) switch enables you to set the CHANNEL 4 (2) input sensitivityto Phono or Line. Note: When using turntables, dont forget to connectthe gro

5、und wire from your tuntable to the ground screw of your mixer.3. The BPM-1 is supplied with 4 sets of OUTPUT (1, 4, 7, 10) jacks. If youare using a turntable and have the input set to phono, thecorresponding output must be connected to phono inputs on yourmixer. If you have the input set to line, th

6、e corresponding output mustbe connected to line inputs on your mixer. Use the CHANNEL 1OUTPUT (10) jacks to connect to the appropriate inputs on your mixer.Use the CHANNEL 2 OUTPUT (7) jacks to connect to the appropriateinputs on your mixer. Use the CHANNEL 3 OUTPUT (4) jacks toconnect to the approp

7、riate inputs on your mixer. Use the CHANNEL 4OUTPUT (1) jacks to connect to the appropriate inputs on your mixer.Operation1. POWER ON: Once you have made all the equipment connections, pressPOWER (13). The power will turn on and the POWER LED (14) willglow RED. When you turn on the BPM-1, the unit w

8、ill run through aninitialization period in which the BPM DISPLAYS (17, 19) and the BEATOFFSET INDICATORS (18) will flash. When the flashing stops, the unitis ready for use.2. The ASSIGN (16, 21) buttons allow you to select which channel will bedisplayed on each side of the BPM-1. Press the ASSIGN (1

9、6) button toselect channel 1, 2, 3 or 4 to be displayed on the left BPM DISPLAY(17). The ASSIGN LED (15) will indicate the channel you selected.Press the ASSIGN (21) button to select channel 1, 2, 3 or 4 to bedisplayed on the right BPM DISPLAY (19). The ASSIGN LED (20) willindicate the channel you s

10、elected.3. BPM DISPLAY: There are BPM DISPLAYS (17, 19) for each side of theBPM-1. They update approximately every 2.5 seconds and digitallydisplay the Beats Per Minute allowing you to match the beats visually.BPM DISPLAY (17) reflects the Beats Per Minute of the channelassigned to the left side of

11、the unit, and BPM DISPLAY (19) reflectsthe Beats Per Minute of the channel assigned to the right side of theunit.NONONONONOTETETETETE: A - - reading will appear on the BPM DISPLAY if thetrack has unclear beats. The - - reading will also appear ifthere is no signal present.4. The BEAT OFFSET INDICATO

12、RS (18) light when the tracks of the twochannels assigned to the crossfader are within 11 BPMs of each otherand display how aligned the beats of the two channels are. When theRED LEDs light, the beats are not aligned. When the YELLOW LEDslight, the beats are almost aligned. When the GREEN LED lights

13、, thebeats are aligned perfectly.NONONONONOTETETETETE: If the difference between the two channels beatsexceed 11 BPM, the BEAT OFFSET INDICATORS will notlight.SUGGESTION: You can use the BPM DISPLAYS to determine whichtracks have similar or the same Beats Per Minute. When mixing two trackswith simil

14、ar Beats Per Minute, you can use one sources pitch control toalign the Beats Per Minute with the other sources BPM. The BPMDISPLAYS and the BEAT OFFSET INDICATORS update every 2.5seconds and will reflect the change in BPM and indicate when the beatsare aligned.NONONONONOTETETETETE: Beat mixing is a

15、skill that requires practice. Notevery track has a strong beat, and beat mixing works bestwith tracks that have clear and strong beats.SpecificationsINPUTS:Phono.3 mV 3 MOhmLine.150 mV 3 MOhmOUTPUTS:Input/Output Resistance.0.1 OhmGENERAL:BPM Range.60 - 180 BPMPower Adapter.115V/15V AC 500 mA230V/15V
