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.

Web Server Port

The port on which the web server is accessed. Default is 0, which in this 
case means port 80.

HTTP Proxy URL

A proxy server can be set up between the web browser and the HTTP server 
to act as a  
go-between. The main reason for this it can provide content filtering and 
can cache responses, meaning subsequent requests for the same content 
can be sent directly. The PS-PLAY and PS-AMP can connect to the internet 
through a proxy server for http functionality.

User Agent

When connecting to a HTTP/IceCast/Shoutcast server a user agent string is 
sent.

Streaming Settings

Stream Check Period

The duration of time that a higher priority stream has to return, before 
it resumes the output from a lower priority stream. To prevent frequent 
switching from an intermittent network, the value is  multiplied by 4 on 
every subsequent drop out. Note that files being played from USB behave 
differently.

Check Period Limit

The highest value that the stream check period can reach.

RTP Delay

This is the processing delay between the decoder input and output. The 
delay should be set large enough to cover any network problems. For MP3 a 
value of 600ms is recommended. Other common values are:

MP3  

600ms

uLaw/ALaw 8kHz mono  

444ms

PCM 8kHz mono  

444ms

uLaw/ALaw 12kHz mono  

316ms

PCM 12kHz mono  

316ms

uLaw/ALaw 24kHz mono  

188ms

PCM 24kHz mono  

188ms

uLaw/ALaw 32kHz mono  

156ms

PCM 32kHz mono  

152ms

PCM 44.1kHz mono  

110ms

PCM 44.1kHz stereo  

79ms

PCM 48kHz stereo  

72ms

Maximum delay is determined by the bit rate of the audio stream & the 
buffer size (64kB).

USB Backup

This option allows you to choose whether a track is interrupted or allowed 
to finish when swapping back to a higher priority stream from the USB 
backup stream. Select ‘play complete file’ to allow the current track to 
finish.

URL Behaviour

Refresh

The stream target is usually scanned once before playing. If ‘periodic’ is 
chosen, the PS-PLAY/PS-AMP will scan throughout the playout too. This 
is useful if the stream is from a server-based play list which is dynamic, 
meaning the content could change. Please note, use ‘Once’ if there is 
limited bandwidth or the server is restricted to one connection per client.
