8、wM1400 and M1400i power amps built after June 15, 1999 have some rather lovelyimprovements. These include:1.Higher output fan for increased cooling The old fan which has an output of 51 CFM hasbeen replaced with a new hi-performance Panasonic FBA0824H1T fan that has 62 CFMoutput. This improves the M

9、1400/1400is cooling capacity by 20%, allowing them to run inan environment 14F hotter than previously without overheating.2.Higher voltage tolerance the four main filter capacitors have been increased involtage rating from 80V to 82V. This improves the ability of the M1400/1400i to handleinstallatio

10、ns and gigs where the AC line voltage is higher than normal.3.Improved speaker protection circuitry Previously, under certain unusual conditions,(such as the SeaHawks winning an away game), the protection circuits could shut downthe amplifier. The circuit is redesigned so instead of shutting down, t

11、he amplifier willmute for two seconds and then begin operation again.4.Other improvements The new designs have improved reliability by changing the designsurrounding the driver transistors, specifying higher quality main 30A bridges, removing allsoldered-in multi-pin cable assemblies in favor of mor

12、e reliable (and more expensive)header to receptacle interconnections, increasing the robustness of the +/-16V powersupplies, and redesigning the baker clamp for improved high power operation.5.New circuit boards The new designs have new circuit boards.6.Handles Removed The new designs have no handle

13、s on the front panel. This is also aquick way of telling if the amplifier is a series II design or not.7.Service Manual The old service manual contains many details which still apply, such ascircuit theory and troubleshooting. This series II manual is just a basic guide to the newschematics, pcbs, a

14、ssembly drawings and parts lists.8.Owners Manual The owners manual was only mildly altered to reflect the new model,so all details of the amplifiers operation are correct.9.Service bulletin The ribbon modification still applies to the “series II” models. See the lastpage of this service manual.5You

15、must perform the following leakage test before returning the unit to your customer.Take every safety precaution to protect yourself while doing this test.1.Make a small loading RC circuit as shown in the diagram below, and connect the ACvolt meter between the AC power source ground and any exposed m

16、etal on the unitunder test.2.Connect the unit under test to an AC power source using a ground-lift adaptor, leavingthe units safety ground floating. Turn the unit on.3.The meter reading should be less than 750mVAC (note: this is equivalent to 0.5mA ofleakage current).4.Flip the plug over in the rece

17、ptical so the hot and neutral are swapped.Verify that the reading is still less then 750mVAC.5.If either reading is greater than 750mVAC, then you must investigate and repair the unitbefore returning it to your customer.Safety testA - 1M1400, M1400i series IIPART#DESCRIPTIONPAGES090-137-XXM1400 asse
