sound of the hum or hiss, or eliminate it. A drop-out situation may
be either better or worse as the crowd fills and/or leaves the room,
or when the transmitter or receiver is operated in a different
location.
The UCR200D receiver offers a sophisticated diversity design
which overcomes drop-out problems in almost any imaginable
situation. In the event, however, that you do encounter a dropout
problem, first try moving the antenna at least 3 or 4 feet from
where it was. This may alleviate the drop-out problem on that
antenna. If drop-outs are still a problem, try moving the antenna to
an entirely different location in the room or moving the antennas in
closer to the transmitter location.
Lectrosonics transmitters radiate power very efficiently, and the
receivers are very sensitive. This reduces drop-outs to an insig-
nificant level. If, however, you do encounter drop-outs frequently,
call the factory or consult your dealer. There is probably a simple
solution.
There are two remote antenna assemblies included with this re-
ceiver. Position the antennas at least three or four feet apart and so
that they are not within 3 or 4 feet of large metal surfaces. If this is
not possible, try to position the antennas so that they are as far
away from the metal surface as is practical. It is also good to
position the receiver so that there is a direct “line of sight” be-
tween the transmitter and the receiver antenna. In situations where
the operating range is less than about 100 feet, the antenna posi-
tioning is much less critical. The antennas can also be configured
with one whip mounted directly onto the rear panel of the
UCR200D receiver, and the other one mounted remotely.
A wireless transmitter sends a radio signal out in all directions.
This signal will often bounce off nearby walls, ceilings, etc. and a
strong reflection can arrive at the receiver antenna along with the
direct signal. If the direct and reflected signals are out of phase
with each other a cancellation may occur. The result would be a
“drop-out.” A drop-out sounds like either audible noise (hiss), or
in severe cases, may result in a complete loss of the carrier and the
sound when the transmitter is positioned in certain locations in the
room. A drop-out normally sounds like “hiss” or a “swishing”
sound. Moving the transmitter even a few inches will change the
