(D) If
AutoConf
is selected, the stream will be automatically configured. To manually configure
the stream, deselect the
AutoConf
button. Tap in the gray boxes that appear to bring up a
virtual keyboard to enter the multicast address and port. The multicast address is computed
from the current IP address of the device as follows: 239.N.AAA.AAA, where N is the
stream number and AAA.AAA are the last two bytes of the device’s IP address. The port is
typically fixed to the default: 5004.

(E) Channel routing. Available AP25 channels may be routed to any of the stream channels.
Select a gray
Route From Chan
box above the stream channel you wish to route to, and
scroll to the AP25 channel desired.
(F) Select the
Sample Rate
from the dropdown menu. Choices are 48000 and 96000. Select
48000 when using the DDR-16/32.
(G)
Volume Control.
When
Local (Digital)
is selected from the dropdown menu, the Master
Fader will control the volume on the receiver DAC using digital processing on the H790 card.
The AES67 signal is attenuated before it is sent to the DAC. This selection will work with
any AES67 DAC.
(H) View SDP. Most receive devices will be able to detect the stream information being
transmitted. Selecting the View SDP button brings up info on the current stream that can be
pasted into a receive device that can’t auto detect the information.
