PS-SEND
Unit Status
The unit status is available on all pages and contains the following
information:
Sending Status
The last recorded status of the unit and it shows either SENDING or
INACTIVE.
Analogue Peak Input Values
The last recorded peak input value displayed in dBs for both channels.
GPI Status
The last recorded GPI input status. Grey box means currently open contact.
Green box means currently closed contact.
Basic Audio Settings
Input Source
Select the input source that will be used by clicking on the appropriate
radio box. Only one can be selected at a time.
Channel Mode
Select whether the source is Stereo or Mono. If mono is selected, both left
and right channels of the network stream contain left channel data. The
stream becomes dual-mono.
Encoding
Choose one of the encoding methods. Then select a sample rate from
‘sample rate’ drop box. Please note that all encoding methods use contant
bit rates. The digital inputs support the following sample rates (all in kHz):
32, 44.1, 48, 88.2, 96, 176.4, 192.
To work out the bit rate for G.711 and PCM, simply multiply the number of
bits (8 for G.711, 16 for PCM) by the sample rate. For example, 8kHz G.711
= 8 * 8000 = 64kBit/s.
MPEG Bit Rate
Select the constant bit rate when MP3 or MPEG2 encoding is selected.
Streaming Mode
Decide when the audio is streamed. The audio can be streamed when:
Send Always
– The audio is always streamed.
Send On Level
– The audio is only sent when the level is above the ‘Trigger
Level’. See Advanced Audio Settings page for more details on the ‘Trigger’
Level.
Send on I/O
– Send when an input is detected and used in conjunction with
Active open/closed and Control GPI.
Stream Destination
Choose how and where the audio data will be sent. Fill in the following
details:
Connection Type
– Select which transmission protocol will be used:
Internet Radio
– HTTP single client server. Set IP to 0.0.0.0 to have the
server act as a TCP listener. In this mode port 0 = 80, the default http port.
When using this method, a radio path should also be set. More information
on the radio path can be found on page 30.
RTP
– RTP or Real Time Protocol connection, based on UDP. Set IP to 0.0.0.0
to broadcast to the subnet or enter a specific IP address.
BRTP
– BRTP or Barix real time protocol, based on RTP for a server up to 32
clients. Set IP to 0.0.0.0 and it will act as a listener waiting for clients on a
selected port.
