Step 1
Choose a Location for the Transmitter
It’s usually most convenient to locate the T4 next to the public address equipment. The
location must have the audio feed and 120 VAC power available. Place the transmitter on a
level surface where there are no substantial metal or other electrically conductive objects
between the antenna and the listening area.
After initial adjustments, there should be no need to access the unit.
Step 2
Choose a Location and Install the Antenna
The T4 is equipped with a short flexible antenna (ANT 021). The ANT 021 threads onto a
stud recessed in a hole on the top of the transmitter. Do not use excessive force to tighten the
antenna; it need only be finger tight.
The T4 Transmitter can also be purchased with a coaxial antenna (ANT 005) or Wall Mount
Dipole Antenna (ANT 024).
See
Remote Antenna Location Tips
on page 11 for more detail.
Step 3
Choose a Channel
Both the T4 Transmitter and R30 Receivers are set to 72.9 MHz at the factory, unless
otherwise specified. However, you may easily set the T4 to any of the 10 available channels
using the FM Channel/FM Power Switch. You may wish to use a different channel if there is
already another hearing assistance system or some other authorized radio service operating
on 72.9 MHz in your area.
Receivers must also be set to the same frequency as the transmitter. See page 22 for receiver
tuning instructions.
Step 4
Choose and Connect an Audio Source
Plug the T4’s audio cable into a Line Out, Record Out, Tape Out or Auxiliary Out jack on
your system amplifier. If these outputs are already in use, a simple Y–cord can be used to
make the connection. Plug the other end of the audio cable into the T4’s Audio Input Jack on
the rear panel. If all line level outputs are in use, the T4’s line out jack on the transmitter’s
rear panel can be used to feed other devices.
IMPORTANT: If you choose to connect to 70 Volt Speaker line, be certain to set the
Audio Config switch correctly. Transmitter damage will occur if you do not.
