Pro Audio Streamers Introduction 1
1. Pro Audio Streamer Introduction
The Pro Audio Streamers are a range of three IP to audio and audio to IP
streamers which have professional analogue and digital inputs and outputs.
They allow audio to be streamed around a building, wan or lan using IP
audio and CAT5 cabling infrastructure. Typical applications include:
• As a backup STL (studio to transmitter link).
• For audio confidence monitoring in remote locations, such as at a radio
transmitter site.
• For distribution of audio and music around a building, such as for passing
audio to speakers in a conference room.
• As an internet-based IP music distribution system.
• As a tannoy, paging or IP based public address system.
• For in-house audio applications and distribution.
• For streaming internet radio in bars and clubs.
• For radio and music channels in hotel rooms distributed via an IP
network.
• For playing audio from a PC, a jukebox application, or from a USB stick.
There are three products in the range providing encoding/decoding and
streaming:
The PS-SEND converts an audio input to an IP stream.
The PS-PLAY reads an IP stream and outputs to balanced and unbalanced
audio line levels.
The PS-AMP reads an IP stream and outputs audio to stereo speakers.
There are versions of the product which are rackmountable in a 1U high
chassis: PS-SENDS, PS-PLAYS and PS-AMPS respectively. The functionality of
the products is the same as the non-rackmount versions.

2. PS-SEND Audio to IP Streaming Encoder
Introduction
SONICIP technology, if selected. Remote level monitoring is also possible
using SNMP traps.
Two red and green front panel LEDs indicate what state the unit is currently
in, be it normal operational mode or bootstrap mode, and also indicates
the current network connection status. A blue LED denotes power to the
unit. The input being routed to the IP stream can be monitored on the front
panel ¼” (6.35mm) stereo jack socket in combination with a headphone
volume knob.
The rear panel has 2 x RJ45 connectors, one for the 10/100Mbit Ethernet
interface and one for GPI connections. The PS-SEND has 6 x GPIs which can
be used to trigger the sending of the audio stream and which can also be
used to trigger remote events using an output relay on the PS-PLAY and
PS-AMP. There is a 9 way D-type RS232 serial connection for control of the
unit by automation systems and firmware updates. The unit can be remote
controlled via serial connection, TCP or UDP.
Power to the unit is via a universal supply 85V - 264V fused IEC mains
socket.
The PS-SEND is a freestanding audio to IP converter which is also available
in a 1U rack-mount as the PS-SENDS. It receives audio from a number of
user selectable external stereo sources including balanced and unbalanced
analogue audio, AES/EBU, S/PDIF & TOSlink digital audio. Once an audio
source is selected, the unit encodes the audio in real time and sends it to
the network as an encoded stream. The audio stream can be distributed
over an IP-based network to one or more PS-PLAY or PS-AMP units or other
proprietary servers such as those for Icecast or Shoutcast.
All the configuration settings for the unit are accessed via a local web-
server built into it. The type of encoding and the transport mechanism
are defined by selecting the connection from a pre-defined list. The
PS-SEND encodes an audio source into an MP3 (from analogue or digital
inputs), G.711 or PCM (from analogue inputs only) audio stream using
HTTP, RTP, raw UDP or raw TCP protocols, including multicast support and
the following encoder types are available: Mpeg1 & 2 Layer3, PM3 VBR
(variable bit-rate), PCM linear and A-law, U-law, with 8kHz-48kHz sample
rates . The unit can configure its own IP address using DHCP/BOOTP, IPzator
or AutoIP. A readout of the set IP address can be heard on every reset using

in a 1U rack-mount as the PS-PLAYS. It takes an IP audio feed and converts
it to a number of simultaneous stereo outputs: balanced and unbalanced
analogue audio, AES/EBU, S/PDIF & TOSlink digital audio outputs.
As for the PS-SEND, all the configuration settings for the unit are accessed
via a local web-server built into it. The unit can decode one of a number
of audio streams, such as those generated by the PS-SEND (MP3, G.711
and PCM) and including Ogg Vorbis and WMA audio files from external
USB as well as from sources such as Shoutcast, Icecast (Internet radio),
VLC and from RTP servers. The unit can receive streams from HTTP (TCP/
IP) and RTP (UDP) protocols, as well as raw TCP and UDP packets. The unit
can also configure its own IP address using DHCP/BOOTP, IPzator or AutoIP.
A readout of the set IP address can be heard on every reset using SONICIP
technology, if selected.
Two red and green front panel LEDs indicate what state the unit is currently
in, be it normal operational mode or bootstrap mode, and also indicates
the current network connection status. A blue LED denotes power to the
unit. The audio output can be monitored on the front panel ¼” (6.35mm)

stereo jack socket in combination with a headphone volume knob. The
analogue audio outputs can be switched to be either a fixed level output or
to be controlled by the front panel volume knob. The volume can also be
adjusted, as well as many other features, using an infra-red remote control
(available separately).
The PS-PLAY can be configured with up to 3 sources. The sources are
prioritized in number order. If one has failed, the next one will attempt to
play. If all fail, an external USB drive will be used as a back-up source. The
external USB plugs into the USB socket on the front of the unit. This enables
the PS-PLAY to act as a USB audio player, playing any of the audio formats
previously mentioned.
The rear panel has 2 x RJ45 connectors, one for the 10/100Mbit Ethernet
interface and one for GPIO connections. The PS-PLAY has 2 output relay
contacts which can be triggered remotely over IP from a connected
PS-SEND unit. There is a 9 way D-type RS232 serial connection for control
of the unit by automation systems and for firmware updates. The unit
can be remote controlled via serial connection, TCP or UDP and remote
management of the unit is also possible using SNMP traps.
