Status block
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 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.
Encoding
Choose one of the encoding methods and sample rates. Please note that all encoding methods use a constant bit rate. If using the digital inputs, MPEG-1 will be used and the sample rate will be detected. The input sample rate can be 32kHz,44.1kHz,48kHz,88.2kHz,96kHz 176.4kHz or 192kHz.
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.
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.
MPEG bit rate
Select the constant bit rate when MP3 or MPEG2 encoding is selected
Stream Destination
Choose how and where the audio data will be sent. Fill in the following details:
Streaming Mode
Choose whether the stream is sent automatically or when an input level is detected on the currently selected input.
Select connection
Choose the stream which you would like to edit.
Connection Type
Select which transmission protocol will be used:
HTTP. Set IP Address to destination address. To stream to more than one destination, enable the other streams in HTTP mode also. For example, if two destinations are required set stream 1 and another to HTTP. In this mode port 0 = 80, the default http port. When using this a radio path should also be set. More information on the radio path can be found on the 'streaming settings' page.
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.
Raw UDP - Select raw UDP for a UDP destination. Set IP to 0.0.0.0 to broadcast to the subnet or enter a specific IP address. In this mode port 0 = 3030
Raw TCP - Select raw TCP for a single TCP client. Set IP to 0.0.0.0 to have server act as a TCP listener. In this mode port 0 = 2020
Icecast source - Set this type to connect to an icecast server and act as an icecast source. Enter the IP and port of the icecast server for the device to act as an icecast source.
Shoutcast source - Set this type to connect to a single shoutcast server. Enter IP and port of the shoutcast server for the device to act as a shoutcast source.
IP Address
Enter the values of the receiver or enter a broadcast address. For the first 4 streams, the IP address can be a URL. For example if HTTP is the connection type, write http://X.X.X.X, where X.X.X.X is the IP Address. For RTP, always use the IP Address only.
Port
Fill in the port number which is being used. If this number is set to 0, the default port number is used.
Network Settings
IP Address
Enter a four digit number to give the unit a unique ID on the network. Remember to ping the address before assigning it to see if it is free otherwise the unit will wait for the address to become free. Alternatively, set the IP to 0.0.0.0 to enable DHCP.
Netmask
Use a netmask to mask the network IP numbers which are common to all devices on the subnet e.g. for a class c network where the first three numbers are common to all devices, use 255.255.255.0.
Gateway IP address
The gateway allows access to the internet and computers outside the LAN. Enter the 4 values into the boxes.
Primary and alternative DNS
A DNS is needed to relate IP addresses to their URLs. Speak to the network administrator to find out the DNS address. An alternative is needed just in case the first one is unreachable.
Please note that if the IP is set to 0.0.0.0 then it is likely that the netmask, gateway and DNS server values will have been automatically set. These can be left as 0.0.0.0 also in this case.
DHCP host name
This name is sent in the DHCP request. If the field is empty a name will be generated based on the mac address. This enables the devices IP to be identified from the DHCP server list.
Audio Settings
A/D amplifier gain
choose the desired amplifier gain from the drop down list.
MP3 Frame CRC
Set to enable to include the crc 16 in each MP3 frame
MP3 Bitresevoir mode
Use this to compensate the difference between frame sizes. Leave the setting empty if you require a low latency or are streaming in RTP mode.
MP3 Channel Mode Extension
Enable or disable MS-Stereo Encoding. When disabled only mono will be encoded. Use this option if you need to preserve bandwidth.
MP3 copyright extension
Enable the copyright protection bit in the MP3 stream
MP3 stream type
Sets the bit to indicate whether the stream is an original or a copy.
MP3 emphasis
Select between emphasis none,50/15us or CCITTj.17

Streaming Settings
Own Name
This is an identification string for the unit so that it maybe identified on the network.
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.
Control GPI
Select which GPI controls the send operation.
Active open/closed
Select whether the an open or closed state on the selected GPI is used to activate the send operation.
Send Contact Closure Information
If sending on I/O and using the RTP transport protocol, the closure of the selected GPI can be sent to the receiving Play or Amp unit, and the relay contacts on that unit are closed.
Trigger Level
When sending from level, this is the level which will trigger the send.
Pre-trigger start
Send a stream from an earlier point than the detected by the trigger. Define an amount of time in ms.
Post-trigger play
Send a stream from a later point than the detected trigger. Define an amount of time in ms.
Buffer under run mode
This defines what happens when a TCP stream is slower than the real stream from he encoder. Once the buffer is under run it can either disconnect the TCP connection or it can skip the stream without disconnecting from TCP.
Stream packet strategy
The streaming strategy defines how a packet is built and sent. On lowest latency the encoded data will be sent directly after the encoding. On optimal strategy the packet will filled before sending.
Radio path
The path is used to identify the stream that is coming from this device, if using the internet radio setting. So to connect to the internet radio stream use the URL, http://x.x.x.x/p where x.x.x.x is the Send's IP address and p is the radio path.
Icy-URL
The Icy-URL is taken into account for shoutcast only. Enter the URL of the web radio station.
Icy-genre
Genre of the streamed music. Used only on Shoutcast source stream.
Shoutcast stream
Select if the stream is private of public. Used only on shoutcast source stream.
Type of service/DSCP
Implemented in Ipv4, the TOS field exists in the header and determines how the datagrams are handled. The field comprises of eight bits, two of which are unused. This leaves 6 bits of data which is divided as follows:
bit 7-5 – Precedence
Set the precedence of the datagram using the following values:
- 000(0) – Routine
- 001(1) – Priority
- 010(2) – Immediate
- 011(3) – Flash
- 100(4) – Flash Override
- 101(5) – Critical
- 110(6) – Internetwork Control
- 111(7) – Network Control
bit 4 – Delay
when set to1 the packet requests a low delay.
bit 3 – Throughput
when set to 1 the packet requests high throughput
bit 2 – Reliability
when set to 1 the packet requests high reliability
bit 1-0 – Unused
DSCP
DSCP or Differentiated Service Code Point is another method for classifying and managing network traffic on IP networks. This is also six bits and is a newer alternative to the TOS bits. Diffserv aware routers use Per-Hop Behaviours which define the packet forwarding properties associated with each class of traffic. The Per-Hop Behaviour is determined by the DS field in Ipv4 or Ipv6 header. The behaviour can be either:
Default – Typically best-effort traffic. Set to 000000.
Expedited Forwarding – dedicated to low-loss, low-latency. Set to 101110.
Assured Forwarding – Assured delivery,see manual for more details
SNMP Settings
Traps can be configured to monitor audio input levels on the PS-Send. The traps are triggered by a level of audio either below or above the set trigger levels. This feature only works on the analogue inputs.
Trap Target IP Address
Enter the IP address of trap target destination
Low Audio Level
The lower limit of the audio, before a trap is triggered.
High Audio Level
The higher limit of the audio, before a trap is triggered.
Trap Repeat
Repeat the trap after this amount of time if the audio remains out of range.
Silence Timeout
The amount of time that the low limit has to be breached before sending a trap.
Control Settings
