BLOCK DIAGRAM EXPLANATIONS (1) Channel Amplifier Section The input signal of each channel is sent to the ming part, There are four channels, and each channel has input from two systems, The respective channels are matched to the connected equipment, 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. Each chanel is equippe with a 3-band equalzer permttig independent control of trim for control of the input signal level and fader volume for high, medium, and low range, (2) Channel Assign and Mixing Section T()ignal from the chanel amplifier is selected with the C :)1: assign switch and is sent to both ends of the cross-fader, The C,F.ldirect mixig switch is used to select mixing only with the source alott to the cross-fader or mig only with the cross-fader, (3) Master Amplifier Section The signal afr ming is processed. The input signal passes balance adjustment and mai volume adjustment and then is sent to the next stage, (4) Monitor Amplifier Section This is the source selection circuit for confirmation of the signal 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 before each channel fader can be monitored, so that signal confirmation is possible in case of trim adjustment and r ming, Also, and adjustable equalizer is installed for c pondence to cases where beat is diffcult to hear with headphones, (5) MIC Amplifier Section There are two mike input systems, the phone type input (submie) at the rear panel and the Canon typ input (mai mike) at the control panel, and the main mike input is equipped with an independent equalizer for high, medium, and low range in addition to volume adjustment. D.JM-500 (6) BMP Detection Section The BMP (Beats Per Minute, a factor indicating the speed of a title as the number of beats per minute) of the signal selected with the monitor select switch are detected, and the BMP value or the beat interval time is displayed. The synchronization of the input signal by frequencies is detected, the BMP of the most stable signal ar selected, and the data are processed by the microcomputer part. The detection modes are real-time mode with data display in real time and average mode with display of stable inormation for a cert tie, and the micromputer executes output accordig to the indication, The beat timing also can be indicated to the beat monitor of the selected chaneL. (7) Effector Section Diverse effects ca be realized with the built-in DSP (Digita Signal Processor), The DSP operation ca be selected with the effector fuction selection switch from pitch shifter, delay/flanger, pan! reverberation/echo, The applicable channels are channels 1 to 4, mike, and master, For increased ease of use in combination with an external equalizer a SENDIRETURN terminal which can correspond to each channel is provided, and input level adjustment is possible, (8) CD Control Section Wlen 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 CDJ-500 II is connected, stop (back cue) is possible in addition to CD player start. This is executed using the relay start function of CDJ-50/CDJ- 500(G) and CDJ-500 II, and interlocked operation with channel fader and cross-fader also is possible. (9) Operation and Display Section The part in regard to display and operation of the built-in fader is executed by a microcomputer. BPM display and its mode switching, control of effect parameters and built-in fader, beat monitor, and level meter display, control, etc. are executed by an 8-bit microcomputer. 8 RadioFans.CN 收音机爱 好者资料库 DJM-500 4.
