Mackie CR3 CR4 L/R Speaker Selector Bypass

Description: These speakers provide really good sound for...

Steps:

1. Turn off your powered speaker, unplug it, and remove the 10 short Phillips head screws on the back that line the perimeter.
2. Once removed, give it a little wiggle, and you can pull out the electronics from the casing pretty easily. A little care is required, as there is cabling connecting it to the speaker front, but there is enough slack that you don't need to worry about disconnecting for this fix.

3. Arrange things so you have easy access to the underside of the circuit board, and the back panel to the right.
4. The contact points we need to work on are the bottom 4 pins in the cluster of 6 pins, directly left of the switch, on the back of the circuit board.
5. For the Powered speaker on the RIGHT, connect the top and bottom connections in that group of 4. Two parallel lines. ||
6. For the Powered speaker on the LEFT, cross the top and bottom connections in that group of 4. Two intersecting lines. X

7. Solder two short insulated wires to bridge the connections to hard wire your powered speaker to either Right or Left as desired. Finished result should look like the photo, (Right powered speaker selection) only cleaner, with no hastily added electrical tape shielding, because you are better at soldering than I am.
8. Do make sure your wires lay pretty flat to the board so it won't get in the way when you slide it back in to the speaker casing.
9. Optional Method: As a few users noted, placing the bare wire from an insulated wire on the pins and soldering them down ALSO WORKS. This method lays more flat, but really only works when doing the right speaker formation since they are parallel lines.
