12. Temporarily turn down the level of your mixer or amplifier and turn off the power
to your transmitter, leaving the AR300 receiver on. Then restore the previously
set level of your mixer or amplifier. With the transmitter off, the receiver output
should be totally silent; if it is, skip ahead to the next step. If it isn’t (that is,
if you hear some noise), you may need to adjust the AR300 Squelch control.
When the Squelch control is at its minimum setting, the AirLine Synth system
always provides maximum range without dropout; however, depending upon
the particular environment your system is used in, you may need to reduce that
range somewhat in order to eliminate band noise when the AL300 transmitter is
turned off. To do so, use the provided screwdriver to rotate the Squelch control
completely counterclockwise (to the “Min” position), then slowly turn it clockwise
until the noise disappears. If no noise is present at any position, leave it at its fully
counterclockwise “Min” position (so as to have the greatest overall range available).
13. When first setting up your AirLine Synth system in a new environment, it’s always
a good idea to do a walkaround in order to make sure that coverage is provided
for your entire performance area. Accordingly, turn down the level of your audio
system and turn on both the transmitter and receiver. Then restore the level
of your audio system and while speaking at a normal performance level, walk
through the entire area that will need to be covered. As you do so, observe the
RF Meter on the AR300 receiver to make sure that it is close to reaching “75%”,
indicating that it is receiving sufficiently strong RF signal. Always try to minimize
the distance between transmitter and receiver as much as possible so that the
strongest possible signal is received from all planned transmission points. In
certain environments, it may be desirable to angle the AR300’s antennas differently
from the vertical position.
If you have followed all the steps above and are experiencing difficulties, contact your
local distributor or, if purchased in the United States, call Samson Technical Support (1-
