Page 9: Introducing Prostream
ProSTREAM encodes the processed audio and muxes the companion real-time program meta data into a compressed web stream. ProSTREAM then connects to a streaming relay server instance or streaming service provider to deliver a rock solid packet stream for Internet clients. -
Page 10: Quick Start
| Section 1 Quick Start In order to quick start a ProSTREAM web stream, a streaming relay server instance can be used to test ProSTREAM functionality. This example uses SHOUTcast DNAS 1.9.8 (Current Stable Version) freely available for major computational platforms from http://www.SHOUTcast.com/broadcast-tools. -
Page 11: Prostream Settings
The output, or encoded audio can be heard by connecting to ProSTREAM with a client audio application. Use a program like VLC or WinAMP to open the network stream connection to port 8000 at ProSTREAM’s IP address[I.E. 192.168.0.10:8000] or open the internal web configuration page. The main configuration page will include playlist links to connect to ProSTREAM’s internal mini-server. - Page 12 | Section 1 The stream can now be heard with a streaming player by connecting to the SHOUTcast base URL or by clicking on the Listen link.

Page 13: Controls And Connections
Controls and Connections Overview The Telos ProSTREAM is very simple to set up and use, having a minimal amount of controls and easy, intuitive interface. Here, we’ll take a look at the front and rear panels of your ProSTREAM. Here’s what you’ll find inside your packing box: Telos Systems ProSTREAM unit ♦... -
Page 14: Connections
The LAN network jack is a 10/100 RJ45 jack and can be used on a Livewire network for source audio and post-process audio monitoring. The LAN network can also be used to access ProSTREAM’s internal web configuration pages. The LAN network may also be used for connection to the stream- ing server instance. -
Page 15: Prostream Controls
ProSTREAM Controls ProSTREAM can be configured via its internal web interface accessible via both the LAN and WAN net- works, as well as via the front panel controls. The web interface can be reached by pointing a web browser to the IP address of either LAN or WAN network. - Page 16 The Audio Output Level affects the signal level for the ProSTREAM’s rear outputs and Livewire returns. [The internal audio bridge from the processor to the encoder is unaffected by the Audio Output Level setting.] The default setting of 0.0 dB will direct the full level of the processed audio to the ProSTREAM outputs. Livewire Input Channel: If you’ve chosen the Livewire interface, you’ll be given fields to assign input and output channels.

Page 17: Network Menu
PROSTREAM CONTROLS | Network Menu The ProSTREAM is equipped with two RJ45 gigabit network ports marked LAN [Local Area Network] and WAN [Wide Area Network]. The networking settings of the ProSTREAM are of IPv4 conventions and must be assigned an IP address before the ProSTREAM will communicate with any other devices. -
Page 18: Status
The status display of the ProSTREAM is the default device display interface and provides a visual representa- tion of the aural states of the ProSTREAM. The status display as shown in the display photo above shows real-time bar graphs representing the metered audio level for each the left and right inputs and post-process outputs. -

“freeze” indicating the processor in the hold mode of the algorithm. This can occur when there is dry vocal audio in the signal. ProSTREAM’s processor is capable of performing many different processing functions at different times. The processing display bar graphs indicate different kinds of operation with different audio sources. This is primarily based on dynamic range differences in source audio. -
Page 20: Limit
Omnia Processing The dynamics processing algorithms in use in the ProSTREAM are based upon Omnia Audio’s highly successful Omnia.3net, which is a hardware-based DSP audio processor. ProSTREAM performs internal calculations on the source audio with precision sufficient to guarantee 24-bit dynamic range. -
Page 21: Getting The Sound You Want
Spreading the adjustment period over a number of days is recommended. Getting the Sound You Want ProSTREAM is designed to minimize the impact of the quality vs. loudness trade-off. If the desire is to process aggressively, here are some suggestions that should help achieve that goal. It’s recommend that be- fore tuning the processor for raw loudness, decide what sonic characteristics are lacking in the final sound. - Page 22 ProSTREAM can change that. The Omnia processing is designed to look at the incoming audio and make the final mix consistently loud without the artifacts or grunge created by older processors. ProSTREAM makes loudness an effortless exercise.

PROSTREAM CONTROLS | density can cause greater listener fatigue. While ProSTREAM’s Omnia processing is designed to minimize fatigue, it is capable of generating large amounts of density that could eventually lead to fatigue. Adding More Detail: When Loudness Isn’t the Last Word The previous examples demonstrate how to heavily process the incoming audio. -
Page 24: Equalization Changes
| Section 3 Equalization Changes Use the following steps to tailor the shape of the overall audio spectrum: Adjust the relative drive settings in the multiband AGC menu. These controls set the drive levels of the multiband AGC sections. Adjust the settings of the multiband mixer controls. Adjust the mixer. -

PROSTREAM CONTROLS | Thunder Bass If your source material has it, ProSTREAM will put it in the mix, and with muscle! Making changes to this characteristic is done using the following parameters, and for maximum effectiveness, in the order listed: In the enhance menu, increase the amount of deep bass boost. -
Page 26: Compression Codec
[http://www.iis.fraunhofer.de/en/bf/amm/produkte/audiocodec/] and includes the codecs as a source component of ProSTREAM. Lossless encoding, like a ZIP or DMG file on a computer allow an end user to un-compress the data and restore all of the original information. In order to gain much greater compression ratios, audio compression employs lossy compression or encoding by making certain assumptions about human hearing. -
Page 27: Channels
Choose from mono or stereo encoding. Bitrate The full spectrum of ProSTREAM encoding can be anywhere from 14-320 kbps for the output data stream bitrate. The output bitrate constraints will differ depending on which codec is selected and whether the encode is set to mono or stereo. -
Page 28: Metadata
Most automation systems will provide an option for submitting metadata to a streaming server. Metadata connections are made to ProSTREAM via TCP or UDP connections to port 9000. If no automated data stream is available, a manual entry form is included in ProSTREAM to allow manual entry of playlist information. -
Page 29: Streams
The SHOUTcast server address should be set to the source URL for the streaming server software. Once set, the ProSTREAM will attempt to open a connection to this network location. Once the connection pipeline is established, the ProSTREAM will push the encoded audio muxed together with the streaming metadata. -
Page 30: System
“Update Software” button will bring up a file browser where the new firmware image file can be updated to the software bank. Once uploaded, ProSTREAM can be rebooted to the new software bank. All existing configuration options will remain intact. -
Page 31: Streaming Servers
HTTP Streaming: ProSTREAM has a built-in mini server on TCP port 8000. This server can accept only a few connections and should not be used as the main streaming server. It is intended to be used for stream monitoring with a player or to have another media server pull the stream from ProSTREAM allowing monitoring of the encoded stream. -
Page 32: Stream Server Service Providers
The streaming service provider will provide the stream configurations for ProSTREAM and return to the client any number of services including stream link URL’s to provide to listeners. A streaming service can also provide failover and optional configurations should a connection be lost. -
