Parameter Guide
8.1 RF Settings
8.1.1 Frequency
This sets the transmission frequency. The range for this parameter depends on the Band. For
normal Band II transmitters the range is 87.5 MHz to 108 MHz. The normal step size is 50 kHz.
Other frequency ranges and step sizes are also available on request. Please contact a sales
representative for more information.
8.1.2 Power
This sets the RF output level in watts. The range and the step size for this parameter depend
on the model of the transmitter. The following table lists all the ranges for the different models
in Watts:
Transmitter Model Minimum Power Maximum Power Step Size
TX5 0.05 5.05 0.05
TX30 5.4 30.15 0.45
TX50 5.4 50.4 0.45
TX300 30.8 310.8 2.8
TX600 60.5 610.5 5.5
TX1000 152 1102 9.5
TX1500 162 1512 13.5
TX2500 520.5 2550 20.5
Note that when setting the power, the unit will automatically adjust the power output to
reach the selected value. This may take a few seconds. During this time, the FWD power indi-
cator in the Status Box will flash to indicate that the unit is still adjusting to reach the selected
power.
8.1.3 MPX Source
This selects the source for the exciter. Options are Internal or External. Internal selects the in-
ternal generator, i.e. the output from the internal audio processor. This option must be se-
lected when the digital or analog inputs are used. External selects the MPX BNC input. This
option must be selected when the transmitter is used with an external audio processor con-
nected to the MPX BNC input.
