No. 4355 102011 (MPP) 112011 (MDC) 122011 (MGR) 112011 (MJJ) Integrated Amplifier MODEL A-9070(B)/(S) Black and Silver models B MPP 230V AC, 50Hz, 290W S MPP 230V AC, 50Hz, 290W B MDC 120V AC, 60Hz, 3.3A S MJJ 100V AC, 50/60Hz, 250W S MGR 220-230V AC, 50/60Hz, 290W A-9000R/9070 Service Procedures 1.Operation check 1) Speaker relays The relay shall be ON about 5 seconds after POWER is ON and shall be OFF immediately after POWER is OFF. 2) Voltage-detection protectors The speaker relay is OFF immediately after D.C. 3V is put at MAIN IN INPUT terminal to check SP:B(L/R). The same as above when D.C. -3v is put at each place. TEST:4-02. 3) Current-detection protectors a) The relay shall be ON when 3 ohm load is connected to each channel under the conditions of peak-to-zero 35V output for L,Rchannels and no load by using the INTEGRA ampifier series designated circuit with 200Hz square wave.Use TEST:2-17 MAIN IN mode input MAIN IN. b) The relay shall be OFF when 1.5 ohm load is connected to each channel under the conditions of peak-to-zero 35V output for L,R channels and no load by using the the INTEGRA ampifier series designated circuit with 200Hz square wave. White LED If a relay goes out, Disconnect input signal immediately. Model Don't continue to do this check 3 seconds or more. 4) FL tube test (All lighting check) A-9000R A-9070 Please confirm the all FL display lights by TEST MODE 'TEST-1-00'. Normal 5) Buttons Dimmer Please confirm by TEST MODE 'TEST-1-01'. 6) DIMMER FL OFF Please push DIMMER button of Remote controller and confirm the brightness of FL display changes and the white LED lights(A-9000R only). 7) Firmware version. Set the test mode "0-01". Please check the Firmware version. 8) Adjustment and Confirmation of Destination a) Please confirm the R1293 on the BADG-0998. Destination When destination is MJJ or MDC or MGR,It is nothing on the PWB. MPP etc When destination is MPP, It exist on the PWB. R1293 b) Set the test mode "0-02".
