Troubleshooting

The IR-TX2 Ch1 or Ch2 "Audio-level Indicator" is not lit:
- Make sure the IR-TX2 is plugged in.
- Make sure the audio input is connected properly. See page 23 - 24.
- Make sure an active audio signal with an adequate level is being sent
to the IR-TX2 transmitter.
- In combined mode: Check the "sync" connection ("sync out" port of
primary transmitter with "sync in" port of secondary transmitter).
No Sound Reproduction by Receivers:
- Make sure the receivers and transmitters are using the same frequency.
- If some of the receivers work but others don't, check for bad batteries or
earphones.
- If none of the receivers work, check to see if the power and audio input
cables are connected to the transmitter. Verify that the ch1 or ch2 audio-
level indicators blink every now and then.
- Check to see if the transmitter is connected properly to the audio sour-
ce. The audio-level indicators should flash on channels that have audio.
- Make certain the transmitter is not covered by objects which would
block infrared light.
Sound Through the Receivers is Weak and Noisy:
- Try adjusting the audio input level (see page 24). If the signal sounds
okay, you may need to reposition the transmitter beam or add an addi-
tional IR-TX2 secondary transmitter to the system.
Buzzing or Humming Noise in Sound System:
- Check for ground loops or noise on the input signal.
- Check if optical interferences are present (see page 19).
If these instructions do not address your problem or the issue persists,
please call Contacta / Contacta or your authorized dealer or representa-
tive.

Mounting Options

Use the included wall- and ceiling fixture set to mount the transmitter as
desired. The set consists of connecting rods, a bracket and a ball-head
clamp. The double-ended connecting rod (featuring ¼" bolts at both ends)
serves to mount two IR-TX2 on top of each other in combination. The IR-
TX2 can also be mounted on any camera tripod with a 1/4" threaded con-
nector.
