Williams Sound T45 Manuel D’Utilisation

36

• Make sure the transformer (TFP 048) is plugged into the transmitter and any remote power switch is on.

• Make sure the electrical outlet is on.

• Make sure the power button on the front of the T45 is pressed to the “on” position.

• Make sure the 24 VDC power supply is working.

• Make sure the RF output is not set to “OFF.” 

• Check to see if there is a signal coming from your audio source. Check and correct your audio source if necessary.

• Check to see if the Headphone Volume Level has been turned all the way down. If so, increase it.

• Check to see if there is an incorrect or defective connection from your audio source. See page 7 for detailed connection 

instructions.

• Check to see if there is noise in the audio source. To find out, disconnect the audio cable. If the noise disappears your noise 

problem is in the source. Correct or repair your audio source.

• Perhaps the Audio Source control is not set to match your audio source input device. See page 15 to properly configure the Audio 

Source control menu.

• Check to see if the Audio Input level is set too high. If the “input overload” is illuminated, then the audio level needs to be adjusted. 

See page 10.

• Check for ground loops or noise on the input signal. See page 9 for more information. Call your Authorized Williams Sound dealer 

or representative.

• The Audio Level Control may be set too high. You’re probably also seeing the +6 level indicator lighting all the time. To correct, 

adjust the Audio Level control on the front of the T45. See page 10.

• It could be that the T45 Audio Processor is set for Normal Compression, which may be inappropriate for the type of program 

being transmitted. Reset the Compressor Gain control to off. See page 17.

• It could be that the T45 Compressor Slope ratio is set to 2:1, which may be inappropriate for the type of program being 

transmitted. Reset the Compression Slope control to 1:1. See page 16.

NOTE: Be sure to listen to the audio transmission on the T45 phone jack prior to checking the receiver reception.

• Check to see if the antenna on the T45 has been disconnected. If so, attach the antenna correctly.

• Check to see if the RF output power on the T45 is set to “OFF.” If so, reset the RF Output control to FULL, MEDIUM or LOW 

power. See page 18.

• Make sure the FM receiver is ON. Make sure the batteries are properly installed (observing proper polarity). If the batteries are 

rechargeable, it may be necessary to charge the batteries overnight.

• Make sure the FM receiver is operating on the same frequency as the T45. Make sure the receiver is operating on the same 

bandwidth as the T45: Wideband or Narrowband. Follow tuning instruction for the receiver and adjust accordingly.
