Setting Up and Using the DA-5H
If necessary, longer runs of standard low-capacitance (50-ohm) coaxial
cabling with BNC connectors can be substituted for the supplied cables.
Note that, even though the DA-5H allows receiver antenna inputs to
be shared, each receiver (and accompanying transmitter) in your
system must still be tuned to a discrete channel for multi-user
operation.
4. Connect the supplied 3-pin “EEC”
plug to the rear panel AC connector and
plug the other end into any grounded AC
socket (see the “DA-5H Grounding
Techniques” section on page 31).
Then depress the front-panel power
switch to turn the unit on. The “Power”
LED will light up.
5. Turn on the power first to all connected wireless components and
then to your audio system. Now we recommend you do a walkaround in
order to make sure that coverage is provided for your entire performance
area. With all transmitters unmuted, and the level of your audio system
set as before, have an assistant walk through the entire area that will
need to be covered while speaking, singing, or playing into each trans-
mitter at a normal performance level. The presence of the DA-5H
should serve to increase the effective transmission range within your
system—if you do find that any new “dead spots” result instead, try
changing the angle of the DA-5H antennas. The basic rule of thumb for
all wireless audio systems is to always try to minimize the distance
between transmitter and receiver as much as possible and also to try to
maintain “line of sight” between the two (that is, the person using the
transmitter should be able to see the receiver antennas). The idea is to
ensure that the strongest possible signal is received from all planned
transmission points. In fixed installations such as A/V or corporate
conference rooms or for extended range applications (where the
transmitters and receivers are more than 150 feet apart), it may be
desirable to remote the DA-5H antennas altogether by using standard
BNC connectors and 50 ohm coaxial cabling that is suitable for up to
1 gigaHertz bandwidth usage.

culties, call Samson Technical Support (1-800-372-6766) between 9 AM
