Disengage. 16) Engage EQ Shift (S3), compare to Fig. 7. Disengage. CLEAN CHANNEL, PRESENCE, VCV, AND REVERB TEST 1)Disengage Channel Select switch- change oscillator to 46dBV. 2)Look at output, compare to Fig. 8. 3)One at a time, turn tone knobs to 0 and compare outputs (resetting to 10 when done): Bass to 0- Fig.9; Mid to 0- Fig. 10; Treble to 0- Fig. 11. 4)Presence to 10- Fig. 12. Reset. 5)Engage EQ shift (S5), compare to Fig. 13. Disengage. 6)Engage VCV (S6), compare to Fig. 14. Disengage. 7)Reverb knob to 10- Fig. 15. Reset. 8)Scope to 50mV/div. Line out (J5) looks like Fig. 14 (different scale). 9)Scope to 5V/div. Headphone outs look like Fig. 8. FOOTSWITCH TEST 1)With a stereo cord, connect RF2 to footswitch jack on front panel. 2)Engage Channel Switch and Lead 2 switch to the front panel. 3)If necessary, push footswitches so both LEDs are off. 4)Compare output to Fig. 8. 5)Engage Channel footswitch, LED on panel & footswitch light. Output goes up. 6)Engage Lead Channel footswitch, footswitch LED lights, output goes up. NOISE TEST 1)Remove oscillator input. 2)Connect speaker to output and listen to noise. It should be clean with no distortion or crackling on both channels. BACKLINE 100 INDENTED BILL OF MATERIALS 11/24/99-SW NOTE:Level 1 refers to main assembly/ combo parts.
