Device configuration

Requires very good internet connection. Could experience issues if connection not optimal
Generates too high bitrates, which are not be supported by the device

The maximum bitrate a SAS220 can handle is limited to a value around the 200kbps.
For Ogg Vorbis a nominal bitrate of 200kbps, could produce higher bitrate values for
difficult audio. When serving to more than one host, the SAS220 needs to process
more date (twice as much for two connections). When network issues would be en-
countered, the SAS220 might need longer more time to transmit the data. All these
need to be considered when deciding what quality to use. The maximum bitrate
limitation also applies to MP3 format.

Device configuration

There are three ways to configure your SAS220 device.

From the web-interface (Streamit device portal)

Via a telnet client

Using the Streamit Terminal Program

The recommended configuration interface for the SAS220 device is the web-interface; implemented as
part of the Streamit device portal. In this document, Streamit device portal and web-interface will be
used interchangeably. By default, all Streamit SAS220 devices will get their configurations from the
Streamit device portal.

Streamit device portal the web-interface for SAS220 devices

The Streamit device portal (

https://devices.streamit.eu

is a free web-service that helps users to

configure and monitor their SAS audio streamer devices, straight out of the box.

The figure below shows how the Streamit device portal is used in combination with SAS220 devices.
