Section 8.1—Repair Procedures

Replacing an Open Resistor

The WATCH Center channel has a resistor that will protect the tweeter, in most cases,

if the speaker is over driven during normal operation. This is done so that the driver is not

damaged. Replace a blown resistor as follows:

1. Determine which driver is not playing music.

2. Remove the appropriate resistor access cover from the enclosure by remov-

ing each of the 10-32 button head machine screws (see Figure 18 for resistor
cover location).

3. Using the appropriate Allen head, unscrew the 4-40 Allen bolt that holds the

resistor to its heatsink.

4. Insert the leads of the new resistor through the binding post hole. Retighten

the binding post.

5. Attach the new resistor to its heatsink using the 4-40 Allen bolt.

6. Re-attach the resistor access cover to the enclosure, making sure not to over

tighten the screws.

Replacing a Bad Driver

If you believe that a driver is blown, make sure that you have tried replacing the pro-

tective resistor before you replace the driver. No sound coming from a driver is often a

blown resistor and not a bad driver. If you need to replace a driver, do so as follows:

1. Using the supplied Allen wrench, remove the machine screws holding the

driver in place.

2. Insert the Allen wrench into one of the driver screw holes 1/8 inch. Gently

lift out the driver, and place it onto the foam pad covering the front baffle.
