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,

).

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,

). 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).
