8、N 收音机爱 好者资料库 Click on any item to open that page ALL BOARDS 4 Overview M1400 and M1400i power amps built after June 15, 1999 have some rather lovely improvements. These include: 1.Higher output fan for increased cooling The old fan which has an output of 51 CFM has been replaced with a new hi-perfor

9、mance Panasonic FBA0824H1T fan that has 62 CFM output. This improves the M1400/1400is cooling capacity by 20%, allowing them to run in an environment 14F hotter than previously without overheating. 2.Higher voltage tolerance the four main filter capacitors have been increased in voltage rating from

10、80V to 82V. This improves the ability of the M1400/1400i to handle installations 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

11、shut down the amplifier. The circuit is redesigned so instead of shutting down, the amplifier will mute for two seconds and then begin operation again. 4.Other improvements The new designs have improved reliability by changing the design surrounding the driver transistors, specifying higher quality

12、main 30A bridges, removing all soldered-in multi-pin cable assemblies in favor of more reliable (and more expensive) header to receptacle interconnections, increasing the robustness of the +/-16V power supplies, and redesigning the baker clamp for improved high power operation. 5.New circuit boards

13、The new designs have new circuit boards. 6.Handles Removed The new designs have no handles on the front panel. This is also a quick 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 as circuit theory an

14、d troubleshooting. This series II manual is just a basic guide to the new schematics, pcbs, assembly 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 mod

15、ification still applies to the “series II” models. See the last page of this service manual. 5 You 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

16、 the diagram below, and connect the AC volt meter between the AC power source ground and any exposed metal on the unit under test. 2.Connect the unit under test to an AC power source using a ground-lift adaptor, leaving the units safety ground floating. Turn the unit on. 3.The meter reading should b

17、e less than 750mVAC (note: this is equivalent to 0.5mA of leakage current). 4.Flip the plug over in the receptical 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 unit before

18、 returning it to your customer.
