32、NUMBER Preparing for TEST MODE Equipment: Oscilloscope, Noise Meter, Stabilized PowerSupply, Amplifier, Speaker, Headphone, FS-5U *Following procedures are not necessary when you just want to identify the version number. Just plug in the PSA Adaptor to the adaptor jack of the unit. 1. Connect Amplif

33、ier, Speaker, Oscilloscope, and Noise Meter to the LINE OUT jacks (L/R) of the unit. 2. Connect the MIDI IN and MIDI OUT jacks with a single MIDI cable. 3. Connect the FS-5U to the FOOT SWITCH jack. 4. Turn the POWER Switch OFF and connect the power supply (+9.0V) to the ADAPTOR jack. IDENTIFYING VE

34、RSION NUMBER/ENTERING TEST MODE 1. Turn the power ON while holding down REC and START button. The version number will be shown on the display as in Fig.1. If Fig.2 shows up on the display, keep on holding REC and START button down, and press ENTERbutton. The FACTORY RESET will then be executed and t

35、he display will change to Fig.1. After a few seconds, the sign on the display will disappear, entering the TEST MODE. Notice that all the LEDs of MUTE, ROLL, BASS, REC, START are lit at this time. 1) LCD CONTRAST CHECK 1. After the Version Number sign disappears, all the dots on the LCD show up. Not

36、ice that the display gradually turns dark. 2) SWITCH CHECK 1. After the LCD display becomes most dark, Fig.3 will appear. Turn the VOLUME knob to MAX. 2. Press the pads in the following order. As you press the pad, you will hear a snare drum sound, while the name of the pad to be pressed next will b

37、e shown on the display. Also, make sure that the LED turns off when pressing MUTE, ROLL, BASS, REC, and START. For FOOT SW, press FS-5U connected to the unit. 3) VOLUME CHECK 1. When the Switch Check ends normally, Fig.4 appears on the display. 2. Turn the volume knobs from MIN to MAX in the order l

38、isted below. When each knobs value is checked from MIN to MAX, Fig.5 appears on the display, followed by Fig.4 showing which knob to be checked next after a few seconds. If the volume pot is at MIN or MAX position before checking, turn it to the center first, then to both MIN and MAX. It doesnt matt

39、er whether you start from MIN or MAX. 4) ENCODER CHECK 1. When the Volume Check ends normally, the upper part of Fig.6 will be shown on the display. 2. The lower part of Fig.6 will appear by turning the Encoder. Notice that the direction you turn and the number of clicks match the sign on the displa

40、y. The check ends when you turn the dial 5 clicks or more clockwise and both counter-clockwise. 5) SOUND CHECK 1. When the Encoder Check ends normally, Fig.7 appears on the display with a sine wave output. 2. The test mode end. Turn the power off. DR-202 Dr.Groove Version 1.00 System Error ! Push EN

Turn the power ON, and set the stabilized power supplys voltage to +5.5V. When Fig.8 appears on the display, it means that the unit is normal.

43、If not, please check IC23 and the circuit around it. After you have checked Fig.8 on the display, turn off the units power. Then set the Stabilized power supplys voltage back to +9.0V. MUTE AND OUTPUT WAVEFORM CHECK 1. Turn the VOLUME knob to the MAX position. Turn ON the power while pressing down b

44、oth KICK2 and SNARE2 button. Fig.7 will appear on the display. 2. If any sound over -80 dBm in JIS-A (IHF) mode on noise meter comes out immediately after the power ON, it is No Good. Please check the circuit around muting. 3. Notice that the volume level gradually increases. 4. Make sure that no wa

45、ve form appears on the oscilloscope, when the VOLUME knob is at the MIN position. 5. Turn the VOLUME knob to the MAX position, the LOW knob to the FLAT, and see if the proper sine wave (-26.0(1.5) dBm, 130(2) Hz) appears in JIS-A (IHF) mode on noise meter and oscilloscope. 6. Turn the VOLUME knob to

46、 the MAX position, the LOW knob to the CUT, and see if the proper sine wave (-32.0(1.5) dBm, 130(2) Hz) appears in JIS-A (IHF) mode on noise meter and oscilloscope. 7. Turn the VOLUME knob to the MAX position, the LOW knob to the BOOST, and see if the proper sine wave (-20.0(1.5) dBm, 130(2) Hz) app

47、ears in JIS-A (IHF) mode on noise meter and oscilloscope. 8. Turn OFF the power. RESIDUAL NOISE AND PLAYING CHECK 1. Turn the power ON without pressing any pads. After a few moments, Fig.9 appears on the display. 2. Turn the VOLUME knob to the MIN position, the LOW knob to the FLAT, and measure the

48、residual noise without pressing any pad. The noise level should be under -78.0 dBm for both LINE OUT L and R, measured with noise meter in JIS-A (IHF) mode. 3. PLAYING CHECK Connect the headphones and press the START button, when Fig.9 is on the display. 4. Turn the VOLUME knob to the MAX position. Make sure that the sound from the headphones or the monitor speakers is not distorted. Also make sure that you dont hear any noise from the both
