At this point, output should be at full power =20Vrms. 14)Current limiter test. Change to a 2 ohm load. Output should be a clean sine wave without clipping and = 12Vrms (+or
2、-) .5Vrms. 15)Turn master up and down to check if it works properly. 16)Set the following: volume and master on 10, no load. 17)Check direct out (J5) pins 2 and 3 = 550mVrms (1.5Vp-p). 18)Check balance out left ( J8) and right (J9). Both should = 5.5Vrms in stereo and mono mode at pins 2 and 3. 19)C
3、heck send (J7). 1.7Vp-p, clean sine wave. Probe at R229. 20)Check headphone jack (J3). Tip = 3.4Vrms / Ring = 3.4Vrms or 13Vp-p clipped. 21)Test return. A) Plug input into return (6). (400Hz 50mVrms sine) 26.0 dB. Output = 4Vrms. B) Line out (J10)= 80mVrms. 22)Change to square signal at input (400Hz
4、 26.0dB). 23)Test tones and filters and compare figures. 24)Chorus test. Note: Trigger is on the channel, the scope probe is on, and connect to D.0 (J5) 1V/div. This will make it possible to make measurements without having trigger problems. An external trigger could also be used. A) Volume at 9 ocl
5、ock B) Master at 10. C) Tones on 5. D) Engage chorus. E) Rate 0/ Depth 0. Deviation = 1.3 sec. / Rate = 1.5 sec. F) Rate 0/ Depth 10. Deviation = 5.0 sec. G) Rate 10/ Depth 10. Rate = .25 sec. H) Disengage chorus. 25)Balance out test. Sine input (400Hz 50mVrms) 26.0dB. A) Volume on 5. B) Master on 1
6、0. C) Tones on 5. Balance out left pins 2 and 3 and balance out right pins should look different. Left should swell up and down to a min. and max. value. Right should do the same, however oscillate right and left. D) Engage chorus. E) Stereo switch out. F) Push in stereo switch (mono mode). Signal o
7、n left and right should look similar, swelling up and down. G) Chorus off. 26)Check speaker cut-off switch. 27)Disconnect input. 28)Proceed with noise and tap test. A) Controls on 10, switch out = noise 60mVrms. B) Controls on 10, contour in = noise 80mVrms. C) Controls on 10, comp. in, sustain 0 =
8、noise 50mVrms. D) Controls on 10, comp. in, sustain 10 = noise 250mVrms. E) Controls on 10, comp. in, sustain 10 = noise 300mVrms. F) Contour in, chorus in = noise 40mVrms. G) Contour in, master on 0= noise 2.5mVrms. Noise should be clean without popping or cracking. SW- Rev. 8/27/99200MB INDENTED B
