Box 6928 Edison, NJ 08818-6928 732-738-9003 (Phone) 732-738-9006 (Fax) RadioFans.CN 收音机爱好者资料库 Page 2 17 18 21 20 19 21 12 3 54 45 6 87 78 9 1110 1011 12 13 14 16 15 RadioFans.CN 收音机爱好者资料库 Page 3 Connections 1. Make sure that the POWER (13) switch is in the off position. The POWER LED (14) will be off. This unit comes supplied with a 15 volt AC adaptor. Plug the adaptor into the rear panel power jack. Then plug the adaptor into a proper power source. 2. Use the 4 stereo PHONO/LINE (2, 5, 8, 11) inputs on the rear panel to connect to the output of your sources. The PH1/LN1 (12) switch enables you to set the CHANNEL 1 (11) input sensitivity to Phono or Line. The PH2/LN2 (9) switch enables you to set the CHANNEL 2 (8) input sensitivity to Phono or Line. The PH3/LN3 (6) switch enables you to 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 sensitivity to Phono or Line. Note: When using turntables, dont forget to connect the ground 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 you are using a turntable and have the input set to phono, the corresponding output must be connected to phono inputs on your mixer. If you have the input set to line, the corresponding output must be connected to line inputs on your mixer. Use the CHANNEL 1 OUTPUT (10) jacks to connect to the appropriate inputs on your mixer. Use the CHANNEL 2 OUTPUT (7) jacks to connect to the appropriate inputs on your mixer. Use the CHANNEL 3 OUTPUT (4) jacks to connect to the appropriate inputs on your mixer. Use the CHANNEL 4 OUTPUT (1) jacks to connect to the appropriate inputs on your mixer. Operation 1. POWER ON: Once you have made all the equipment connections, press POWER (13). The power will turn on and the POWER LED (14) will glow RED. When you turn on the BPM-1, the unit will run through an initialization period in which the BPM DISPLAYS (17, 19) and the BEAT OFFSET INDICATORS (18) will flash. When the flashing stops, the unit is ready for use. 2. The ASSIGN (16, 21) buttons allow you to select which channel will be displayed on each side of the BPM-1. Press the ASSIGN (16) button to select 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 be displayed on the right BPM DISPLAY (19). The ASSIGN LED (20) will indicate the channel you selected. 3. BPM DISPLAY: There are BPM DISPLAYS (17, 19) for each side of the BPM-1. They update approximately every 2.5 seconds and digitally display the Beats Per Minute allowing you to match the beats visually. BPM DISPLAY (17) reflects the Beats Per Minute of the channel assigned to the left side of the unit, and BPM DISPLAY (19) reflects the Beats Per Minute of the channel assigned to the right side of the unit. NONONONONOTETETETETE: A - - reading will appear on the BPM DISPLAY if the track has unclear beats. The - - reading will also appear if there is no signal present. 4. The BEAT OFFSET INDICATORS (18) light when the tracks of the two channels assigned to the crossfader are within 11 BPMs of each other and display how aligned the beats of the two channels are. When the RED LEDs light, the beats are not aligned. When the YELLOW LEDs light, the beats are almost aligned. When the GREEN LED lights, the beats are aligned perfectly. NONONONONOTETETETETE: If the difference between the two channels beats exceed 11 BPM, the BEAT OFFSET INDICATORS will not light. SUGGESTION: You can use the BPM DISPLAYS to determine which tracks have similar or the same Beats Per Minute. When mixing two tracks with similar Beats Per Minute, you can use one sources pitch control to align the Beats Per Minute with the other sources BPM. The BPM DISPLAYS and the BEAT OFFSET INDICATORS update every 2.5 seconds and will reflect the change in BPM and indicate when the beats are aligned. NONONONONOTETETETETE: Beat mixing is a skill that requires practice. Not every track has a strong beat, and beat mixing works best with tracks that have clear and strong beats.
