3. Select the audio source by checking either the HDMI or Analog box (see figure 53,
1
).
4. Ensure the Audio Status shows a valid audio source type (see figure 53,
2
). If it does
not, see Audio Input Selection on page 54.
5. Ensure that Compression is set to no compression (see figure 53,
3
).
6. If a reverse audio signal is required, select a source from the Reverse Audio Source
drop‑down list (see figure53,
4
).
NOTE: This menu is only populated when a program audio stream is enabled and
connected on the corresponding decoder, which must also have return audio
enabled.
7. Set the Analog program audio input level (see figure 53,
5
) and the return audio output
level (see figure 53,
6
) to obtain an undistorted signal with optimum signal to noise
(see Analog input level — program audio on page 54 and Analog output level —
return audio on page 55).
8. If RTP multicast source streaming is required, select Multicast Enable (see
figure53,
7
). If RTP unicast is required, ensure the box is deselected.
ATTENTION: Use the same transport type for all streams. Check that the
Multicast Enable setting on the data tab is the same as that on the video (see
step 14 on page 67).
