FAST SETUP PROCEDUREStep 1Choose a Location for the TransmitterIt’s usually most convenient to locate the T4 next to the public address equipment. Thelocation must have the audio feed and 120 VAC power available. Place the transmitter on alevel surface where there are no substantial metal or other electrically conductive objectsbetween the antenna and the listening area.After initial adjustments, there should be no need to access the unit.Step 2Choose a Location and Install the AntennaThe T4 is equipped with a with a short flexible antenna (ANT 021). The ANT 021 threadsonto a stud recessed in a hole on the top of the transmitter. Do not use excessive force totighten the antenna; it need only be finger tight.The T4 Transmitter can also be purchased with a with a coaxial antenna (ANT 005) or WallMount Dipole Antenna (ANT 024).See Remote Antenna Location Tips on page 11 for more detail.Step 3Choose a ChannelBoth the T4 Transmitter and R7 Receivers are set to 72.9 MHz at the factory, unlessotherwise specified. However, you may easily set the T4 to any of the 10 available channelsusing the FM Channel/FM Power Switch. You may wish to use a different channel if there isalready another hearing assistance system or operations by some other authorized radioservice operating on 72.9 MHz in your area.Receivers must also be set to the same frequency. See page 20 for receiver tuninginstructions.Step 4Choose and Connect an Audio SourcePlug the T4’s audio cable into either Line Out, Record Out, Tape Out or Auxiliary Out jackon your system amplifier. If these outputs are already in use, a simple Y–cord can be used tomake the connection. Plug the other end of the audio cable into the T4’s Audio Input Jack onthe rear panel. If all line level outputs are in use, the T4’s line out jack on the transmitter’srear panel can be used to feed other devices.IMPORTANT: If you choose to connect to 70 Volt Speaker line, be certain to set theAudio Config switch correctly. Severe damage will occur if you do not.4Williams Sound ®Helping People Hear
