Trouble Shooting

TX9 Indicator Light Is Not On.

•  Make sure the transformer is plugged into the emitter and any remote power switch is on.
•  Make sure the electrical outlet is on.
•  Make sure the 24 VAC power supply is working.

Only TX9’s Power Indicator LED Comes On.

•  Make sure the MOD 232 is on.
•  Make sure the baseband cable is connected properly. See page 5, Figures 3 & 4.
•  Check to see if the carrier light on the MOD 232 is on.
•  Make sure an audio signal is being sent to the MOD 232.

No Sound Through Receivers.

•  If some of the receivers work but others don’t, check for bad batteries or earphones on the receivers that aren’t 

working.

•  If none of the receivers work, check to see if the power and baseband cable are connected to the emitter and that 

the TX9 Power and Baseband Present Indicator lights are ON.

•  Check to see if the modulator is connected properly to the sound system. The Frequency Indicator should be lit and 

there should be activity on the MOD 232 Level Indicators.

•  Make sure the “eye” is not covered up on the receiver. There must be clear line of sight between the receiver eye 

and the emitter panel.

Sound Through The Receivers Is Weak And Noisy.

•  Make sure each channel is set to a different frequency on the MOD 232 modulator. Listen to the audio signal through 

the Phones jack of the MOD 232 modulator. You can also hold a receiver in front of the Infrared Test LED on the front 

of the MOD 232 modulator and listen to the audio signal. If the signal is weak and noisy here, check the Input Level 

switch and Input Level Control settings. Increase the input signal level from the sound system by turning up the mixer 

control. If the signal sounds okay, you may need to re-position the emitter panels or add additional panels. 

NOTE: Make sure the powerline voltage does not fall below 94V, or system performance will be greatly reduced!

Buzzing Or Humming Noise In Sound System.

•  Check for ground loops or noise on the input signal. Call your Authorized Williams Sound dealer or representative.
