INTRODUCTION
• What’s all this “series II” stuff anyway?
The designation “series II” is an internal Mackie way of describing the new M1400 and
M1400i amplifiers built after June 1999. You will not see “series II” written on any of the
advertising, boxes or silkscreens. One clue is that the series II amps do not have handles.
The serial number prefix also indicates if the amplifier is a series I or II:
The M1400 Series I serial numbers start with a prefix “AH,” (use the other M1400 service manual)
The M1400 Series II serial numbers start with a prefix “DB” (use this manual)
M1400iSeriesI serialnumber prefixis “AM”(use the otherM1400 servicemanual)
M1400i Series II serial number prefix is “DA” (use this manual)
This manual contains basic service information. It is essential that you have a copy of the
user’s manual as this contains the complete operating instructions.

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-performance Panasonic FBA0824H1T fan that has 62 CFM
output. This improves the M1400/1400i’s cooling capacity by 20%, allowing them to run in
an environment 14°F hotter than previously without overheating.
2. Higher voltage tolerance – the four main filter capacitors have been increased in
voltage rating from 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 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 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– 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 and troubleshooting. This series II manual is just a basic guide to the new
schematics, pcbs, assembly drawings and parts lists.
8. Owner’s Manual– The owner’s manual was only mildly altered to reflect the new model,
so all details of the amplifier’s operation are correct.
9. Service bulletin– The ribbon modification still applies to the “series II” models. See the last
page of this service manual.

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 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 unit’s safety ground floating. Turn the unit on.
3. The meter reading should be less than 750mVAC (note: this is equivalent to 0.5mA of
leakagecurrent).
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 returning it to your customer.

FR series Amplifier ribbon replacement instructions (NEW! IMPROVED! July 2000)*
Models affected: FR series M1200, M1400, M1400i
M1200: All models. M1400i: Before Serial # DA20889 and all models with “AM” prefix.
M1400 and 230v versions: Before Serial # DB12700 and all models with “AH” prefix.
Add this as part of your normal repair procedures.
Note: This bulletin replaces all previous ribbon bulletins.
Symptom:
Ch.1 or 2 output signal intermittently fades out, or cuts out completely and/or the DC supply rail fuses blow.
Possible Cause:
The two ribbon cables from the input board may be defective
Solution:
*Replace the input ribbon cables with an improved type in all of the above models, (including any which
have had the previous ribbon bulletin completed).
Safety Warning:
Caution! These instructions are for use by qualified personnel only. To avoid electric shock, do not
perform any servicing unless you are qualified to do so. Refer all service to qualified personnel.
Tools Required:
Phillips screwdriver, Torx and Allen drivers, needle nose pliers, safety glasses.
Parts Required:
040-359-00 Ribbon cable, 28GA, 20 Pin, Length 4.25”, PLZD Quantity = 1
040-360-00 Ribbon cable, 28GA, 20 Pin, Length 18”, PLZD Quantity = 1
400-077-00 20 Pin Headers Quantity = 2
Procedure:
1. Remove all cords (including the power cable and speaker outputs) from the amplifier.
2. Take off the top cover and inspect the ribbon cables. If they are not marked 040-359-00 or
040-360-00 then proceed as follows:
Remove the input board:
3. Undo the XLR screws, TRS nuts, and pull out the four pot knobs.
4. Disconnect the short ribbon cable from the amp board, and the long cable from the front panel
display board. On later amplifiers, you will have to remove the front display board first.
5. Disconnect the black ground wire from the amp board.
6. Undo the four screws on the right side of the chassis. This will give enough room to pull out the input
board. Catch the two metal XLR plates before they fall inside (not present on later amplifiers).

Input board work:
If the two ribbon cables are soldered to the input board, follow steps 7 to 11. If not, then go to step 12.
7. Remove the metal shield plate and insulator sheet from the back of the input board.
8. Carefully unsolder the ribbon cable headers from J16 and J11.
Discard part# 040-033-03, 4 inch ribbon cable.
Discard part# 040-033-02, 18 inch ribbon cable.
9. Solder two new headers (#400-077-00) to the input board, with the cutout side pointing towards
the center of the input board (i.e. downwards).
10. Replace the metal shield plate and insulator sheet onto the back of the input board.
11. Add part# 040-359-00, 4.25 inch ribbon cable to J11.
Add part# 040-360-00, 18 inch ribbon cable to J16.
Align each cable’s color stripe with the header’s pin 1.
Make sure both ribbons are fully inserted, then proceed to step 15.
If the two ribbon cables are not soldered to the board, follow steps 12 to 14.
12. Discard part# 040-062-00, 4.25 inch ribbon cable.
Discard part# 040-062-02, 18 inch ribbon cable. You may have to undo the display board screws
in order to remove it from J1.
13. Add part# 040-359-00, 4.25 inch ribbon cable to J11.
Add part# 040-360-00, 18 inch ribbon cable to J16.
Align each cable’s color stripe with the header’s pin 1.
Make sure both ribbons are fully inserted.
14. Refit the display board, once the long ribbon cable is securely attached to J1.
Putting the input board back in:
15. Add the two metal XLR plates (where fitted) and carefully fit the input board back in place. Put
the four pot knobs back after the board is in place.
16. It can be difficult getting the knobs back on through the chassis holes, but you can make it easier
by snipping off a bit of the plastic center ridge, as shown in the little knob diagram below.
17. Add and tighten all the nuts and screws, and the four chassis screws (removed in step 6).
18. Make sure that all ribbon cables are secure and that all ends are fully inserted.
19. Reconnect the black wire from the input board to the amp board.
20. Replace the top cover.
21/ Perform a complete specification and safety test before returning the unit to the customer.
