38、is sent to the ming part,There are four channels, and each channel has input fromtwo systems,The respective channels are matched to the connectedequipment, channell is CDILIN, chanel 2 is CDIPHONO,chanel 3 is LINHONO, chanel 4 is MIC (sub)IPHONO,and selection is made with the input selector switch.E

39、ach chanel is equippe with a 3-band equalzer permttigindependent control of trim for control of the input signallevel and fader volume for high, medium, and low range,(2) Channel Assign and Mixing SectionT()ignal from the chanel amplifier is selected with theC :)1: assign switch and is sent to both

40、ends of the cross-fader,The C,F.ldirect mixig switch is used to select mixing onlywith the source alott to the cross-fader or mig only withthe cross-fader,(3) Master Amplifier SectionThe signal afr ming is processed.The input signal passes balance adjustment and mai volumeadjustment and then is sent

41、 to the next stage,(4) Monitor Amplifier SectionThis is the source selection circuit for confirmation of thesignal of each chanel with headphones etc.The input signal can be selected from channels 1 to 4, mie,effector, and master. For channels 1 to 4, the signal beforeeach channel fader can be monit

42、ored, so that signalconfirmation is possible in case of trim adjustment andr ming, Also, and adjustable equalizer is installed forc pondence to cases where beat is diffcult to hear withheadphones,(5) MIC Amplifier SectionThere are two mike input systems, the phone type input(submie) at the rear pane

43、l and the Canon typ input (maimike) at the control panel, and the main mike input isequipped with an independent equalizer for high, medium,and low range in addition to volume adjustment.D.JM-500(6) BMP Detection SectionThe BMP (Beats Per Minute, a factor indicating the speed ofa title as the number

44、 of beats per minute) of the signalselected with the monitor select switch are detected, and theBMP value or the beat interval time is displayed.The synchronization of the input signal by frequencies isdetected, the BMP of the most stable signal ar selected, andthe data are processed by the microcom

45、puter part. Thedetection modes are real-time mode with data display inreal time and average mode with display of stableinormation for a cert tie, and the micromputer executesoutput accordig to the indication,The beat timing also can be indicated to the beat monitor ofthe selected chaneL.(7) Effector

46、 SectionDiverse effects ca be realized with the built-in DSP (DigitaSignal Processor),The DSP operation ca be selected with the effector fuctionselection switch from pitch shifter, delay/flanger, pan!reverberation/echo,The applicable channels are channels 1 to 4, mike, andmaster, For increased ease

47、of use in combination with anexternal equalizer a SENDIRETURN terminal which cancorrespond to each channel is provided, and input leveladjustment is possible,(8) CD Control SectionWlen a CDJ-50/CDJ-500(G) is connected to channell or 2,the CD player can be stared from this unit.In the same way, when

48、CDJ-500 II is connected, stop (backcue) is possible in addition to CD player start. This isexecuted using the relay start function of CDJ-50/CDJ-500(G) and CDJ-500 II, and interlocked operation withchannel fader and cross-fader also is possible.(9) Operation and Display SectionThe part in regard to

49、display and operation of the built-infader is executed by a microcomputer. BPM display and itsmode switching, control of effect parameters and built-infader, beat monitor, and level meter display, control, etc. areexecuted by an 8-bit microcomputer.8DJM-5004.
