Setup
1. Mount a tuned coaxial antenna to the DA40
front-panel antenna IN A input by inserting
it into the BNC connector (this connector
is keyed, so that you may have to rotate the
antenna to fully seat it on the connector).
Then twist the outer ring of the antenna
clockwise until it clicks into place. Repeat
the same procedure to mount the other
antenna into the front-panel antenna IN B
input. Note that both antenna inputs are
phantom powered; take care not
to short them.
2. Make connections between
the rear-panel antenna outputs
(A1–A4) to the Antenna A
input connectors on the
wireless receivers. Then make
the connections between the
rear-panel antenna outputs
(B1–B4) to the Antenna B input
connectors on the wireless
receivers.
3. If you are powering the
connected receivers from
the DA40, use the supplied
barrel-to-barrel DC cables to
connect the DC Out jacks on
the DA40 to the DC inputs of
the receivers.
4. Connect the supplied DC adapter to the DA40 rear panel POWER IN jack and plug the
adapter into a AC socket. Press and hold the front power POWER switch to turn the unit
on. The power indicator 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. If you do find that any new dead spots result,
try changing the angle of the DA40 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.
