For a talkback session you must configure the DEC-3
00™ decoder and the ENC-300™ encoder.
To start the talkback session you must configure the DEC-3
00™ webpage. Please open the DEC-300™ webpage,
3
00™ webpage, select in the main menu ‘DECODER’ and click in the submenu ‘AUDIO’. See
Figure 10 on page 22.
Enter in the ‘Talkback IP’ field the IP-address of the encoder with which the DEC-300™ should start
the talkback session. For example: A DEC-3
00™ should start a talkback session with an ENC-300™.
The encoder has the IP-address 172.16.20.100. So you must enter in the
‘Talkback IP’ field of the
DEC-3
00™ webpage the IP-address of the encoder, in this case 172.16.20.100.
Next, the talkback port number must be entered in the ‘Talkback Port’ field. The decoder and the
encoder must always have the same talkback port number. So please enter in the ‘Talkback Port’ field
of the DEC-300
™ your desired port number for the talkback session. This talkback port number must
also be set in the ENC-300
™ webpage.
Now, you must select in the field ‘Talkback Rate’ your desired sample rate, which should be used from
the decoder. The decoder and the encoder must always use the same sample rate. So, the set
talkback rate must also be set in the ENC-300
™ webpage.
Furthermore, please select in the drop-down-
field ‘Input’ the corresponding audio input for the talkback
function. If you supply the DEC-300
™ with the audio signal from a microphone, you must select in the
drop-down-
field ‘Input’ the parameter ‘MIC’. If you supply the DEC-300™ with a line level signal (e. g.:
the audio signal from a DVD-Player), you must select in the drop-down-
field ‘Input’ the parameter
‘LINE’.
You can also set the gain in the fields ‘LineIn Gain’ and ‘MicIn Gain’ for the corresponding audio input,
which you have set in the 'Input' drop-down-field.
The DEC-300
™ is totally configured for a talkback session now. As next you must configure the ENC-
300
™ webpage. Therefor please open the ENC-300™ webpage, select in the main menu ‘ENCODER’
and click in the submenu ‘AUDIO’. Here you must enter the talkback port number in the ‘Talkback
Port’ field. The port number which you enter must be the same port number which you have entered
on the decoder side. Furthermore you must select
in the field ‘Talkback Rate’ the sample rate, which
you have selected on the decoder side. If you have an stereo audio signal, you can enable the
‘Talkback Stereo’ check-box. You can also set the output gain level in the ‘Output Gain’ field and you
can mu
te the audio of the talkback session by enabling the ‘Output Mute’ check-box.
