Please contact Mackie Tech Support (1-800-898-3211) to receive a Service Request Number and Order Number for parts needed for this restoration.
3 Led PCB replacement: 3 Carefully begin to remove the grill. Do not fully remove the grill as the cable is still fi rmly attached to the led PCB assembly. 2 Keep the six screws in a safe place. 4 Carefully remove the cable attached to the led PCB assembly.
4 6 Carefully remove the led PCB assembly from the back side of the grill. Led PCB replacement continued: 7 The hard part is done, the rest is easy! Place the new led PCB assembly (part #0007334) where the old one was. Follow the same steps as above, but backwards 6 to 1.
5 Woofer replacement: 1 Follow steps 1-4 of the led PCB replacement instructions, as the grill will need to be removed in order to access the woofer. 2 Eight screws and washers need to be removed from the woofer using the 4mm allen wrench. 3 Keep the eight screws and fl at washers in a safe place.
6 Woofer replacement continued: 6 Remove the cables from their terminals simply by pushing down on the terminal and pulling out the cable. 7 This is what it looks like with the grill and woofer removed. Place the new woofer (part #0013918) where the old one was.
7 High Frequency Driver replacement: 1 Follow steps 1-4 of the led PCB replacement instructions, as the grill will need to be removed in order to access the high frequency driver. 2 Eight screws and washers need to be removed from the horn using the phillips head screwdriver.
8 High Frequency Driver replacement continued: 5 The positive (solid blue) and negative (blue and black) cables are still attached to the high frequency driver terminals. Remove the cables from their terminals simply by pushing down on the terminal and pulling out the cable.
9 High Frequency Driver replacement continued: 9 The high frequency driver should easily lift right off of the horn assembly. Holding down the horn assembly with one hand while lifting up on the driver with the other hand may help. 8 Keep the four headless screws in a safe place, as well.
10 3 The horn is shown above with the high frequency driver circled. Four screws need to be removed from the driver using the 3mm allen wrench. 4 Keep the four screws in a safe place. 5 The diaphragm and plate adapter are easily removed from the horn assembly.

13 7 Place the new ampli fi er assembly (part #0013838-00) where the old one was. Follow the same steps as above, but backwards 6 to 1. Remove the serial number from the faulty ampli fi er assembly (as shown in picture above) and place on the new ampli fi er assembly.
