TURNING OFF DC MICROPHONE POWER

The T17 is designed to supply positive DC voltage to the plug tip of 2-wire, “barefoot”

electret (power condenser) microphones. If you will be using the T17 with a non-Williams

Sound, Lo-Z (dynamic) microphone, this DC power should be turned off. (See Figure 4.) If

you use both the Microphone input and the Audio Input on the T17, the signals will be mixed

together.

Step 1: Unplug the power cord from the T17 and remove its antenna.

Step 2: Use a phillips-type screwdriver to loosen the two screws on the rear of the

Transmitter. Remove the cover. Slide the circuit board out of the case.

Step 3: Use the diagram to locate the HD4 Jumper. This black jumper is also labeled on the

T17 circuit board.

Step 4:

Pull the HD4 Jumper off the two pins it connects. DO NOT MAKE ANY OTHER

ADJUSTMENTS! For handy storage, simply turn the jumper sideways and place it on just

one of the two pins.

Step 5: Re-assemble the Transmitter.
