WEEE & RoHS Directives - Sonifex Statement

The Waste Electrical and Electronic Equipment (WEEE) Directive was agreed on 13 February 2003, along with the related Directive 2002/95/EC on Restrictions of the use of certain Hazardous Substances in electrical and electronic equipment (RoHS).

The Waste Electrical and Electronic Equipment Directive (WEEE) aims to minimise the impacts of electrical and electronic equipment on the environment during their life times and when they become waste. It applies to a huge spectrum of products. It encourages and sets criteria for the collection, treatment, recycling and recovery of waste electrical and electronic equipment. All products manufactured by Sonifex Ltd have the WEEE directive label placed on the case. It gives a contact for individuals who are unsure about the correct procedure when the product has reached its “end of use”.

Sonifex Ltd will be happy to give you information about local organisations that can reprocess the products, or alternatively all products that have reached “end of use” can be returned to Sonifex and will be reprocessed correctly free of charge.

Sonifex Ltd has phased out the use of certain hazardous substances identied in the European Union’s Restriction of Hazardous Substances (RoHS) directive. The RoHS directive limits the use of certain hazardous substances currently used in EEE manufacture, including lead, mercury, cadmium, hexavalent chromium, and halide-containing compounds PBB (polybrominated biphenyl) and PBDE (polybrominated diphenyl ether). Elimination of these substances will result in more environmentally friendly recycling of electronic equipment. For the products which Sonifex manufacture, the main area where products were aected was in the use of lead for manufacturing and assembling electronics circuit boards.

Sonifex Ltd practices lead-free (LF) manufacturing processes. LF solder is used on the surface-mount PCB manufacturing processes and for hand soldering. The printed circuit boards (PCBs) used are either gold plated, or immersion tin plated, both of which use no lead. Historically the PCBs were hot air solder levelled (HASL) PCBs which used tin/lead based solder.

The manufacturing processes include the assembly of purchased components from various sources. Product is oered as RoHS compliant, or LF, only after sucient evidence is received from the component manufacturers that their components are RoHS compliant. Sonifex Ltd relies solely on the distributor, or manufacturer, of the components for identication of RoHS compliance. Thus whilst every eort is made to ensure compliance, Sonifex Ltd makes no warranty, or certication, or declaration of compliance concerning said components.

Sonifex Ltd denes “Lead Free” as pertaining to any product, which has been manufactured by Sonifex Ltd using components which have been declared by the manufacturers as “Lead Free”. All statements by Sonifex Ltd of RoHS compliance are based on component manufacturer documentation.

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.

Pro Audio Streamers User Handbook

PSSEND AUDIO TO IP STREAMER

PS-SEND Audio to IP Streaming Encoder

Introduction

The PS-SEND is a freestanding audio to IP converter which is also available in a 1U rackmount 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 conguration settings for the unit are accessed via a local web-server built into it. The type of encoding and the transport mechanism are dened by selecting the connection from a pre-dened 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 congure 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. Remote level monitoring is also possible using SNMP traps.

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 rmware 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.

PSPLAY IP TO AUDIO STREAMER

PS-PLAY IP to Audio Streaming Decoder

Introduction

The PS-PLAY is a freestanding IP to audio converter which is also available 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 conguration 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 AAC+V2, Ogg Vorbis and WMA audio les 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 congure 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 xed 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 congured 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 rmware 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.

How To Use Your Pro Audio Streamers

This section of the manual outlines some applications and the webpage settings for them.

Point To Point Audio Send

When used in conjunction with a PS-PLAY or PS-AMP, the PS-SEND can be used to transfer audio from one place to another. The PS-SEND encodes the audio and sends it directly to the PS-PLAY or PS-AMP, which decodes the signal back into audio.

The following guide will show you how to congure your units to stream 44.1kHz mp3 audio to one another when connected on the same local network (LAN):

1. Connect to the webpage of the PS-SEND.

Under the AUDIO SETTINGS header:

2. Select the appropriate input by clicking on the radio button.

3. In the Encoding and Frequency boxes, select MPEG1/ 44.1kHz(MP3).

4. In the MPEG Encoding quality box, select a minimum of ‘5’ for audio.

Under the STREAM DESTINATION header:

5. In the connection type box, select ‘Internet radio’.

6. In the port box, type ‘80’.

7. Press Submit.

The unit will now reset, with the new settings stored.

8. Connect to the PS-PLAY or PS-AMP webpage.

Under the STREAMING header

9. Type http://x.x.x.x:80/pssend , where x.x.x.x is the IP address of the PS-SEND unit.

10. Press Apply.

The unit will now reset and the stream should begin playing.

The following guide will show you how to set up your units to stream 44.1kHz mp3 from one unit to the other when connected to external networks. This is suitable for scenarios such as a Studio Transmitter Link:

Pro Audio Streamers User Handbook

HOW TO USE YOUR PRO AUDIO STREAMER

How To Congure an STL Stream of 44.1kHz mp3 From PS-SEND To PS-PLAY Or PS-AMP

1. Set the PS-SEND up as previously given.

2. Connect to the IP address of the router and congure port forwarding so that:

The router should now allow communication on that port number from the outside world.

Now at the PS-PLAY or PS-AMP site:

3. Connect to the PS-PLAY or PS-AMP webpage.

Under the STREAMING header:

4. Type http://x.x.x.x:80/xstream, where x.x.x.x is the IP address of the router where the PS-SEND is.

5. Press Apply.

Using the PS-PLAY or PS-AMP as a USB Playout System

One of the great features of the PS-PLAY and PS-AMP is that they can be used to play directly from the USB stick plugged into them. This is really useful if a local audio source is needed as a backup for an internet stream or if you simply want to switch to a local playlist. The unit can play AAC+, WMA, MP3 and ogg vorbis les directly from the drive, as well as other streams.

1. Connect the USB stick with a correctly formatted playlist le. There are many free applications available on the internet which will create a .m3u playlist le for you.

2. In the data section there are 3 URL boxes. Choose any URL and type le://x.m3u , where x should be replaced by the name of the playlist.

3. Press Apply.

4. If you chose URL1, the unit will play directly from USB. If you chose URL3, the unit will attempt to play URL1 and URL2, before playing URL3. Thus the USB can be used as a backup for if URL1 and URL2 fail.

5. It is a useful idea to make a playlist of all the streams that are intended to be used, store it on the USB stick and then set URL one to read from the USB playlist. You can then cycle through the dierent streams at your leisure with the remote control. URL2 can be set to play another playlist, which contains local tracks as a backup.

ADVANCED

Advanced

This section of the handbook deals with advanced webpage settings and also contains information found in the Help section of the webpage for reference.

Boot Modes

The unit can congure its own IP address via several methods: DHCP/BOOTP, IPzator or AutoIP.

BOOTP/DHCP – These are methods are used for automatic assignment of an IP address. BOOTP is older and DHCP is more widely used. BOOTP sets the IP address and the gateway address, while DHCP will set IP address, netmask, gateway and DNS servers.

If there is no DHCP/BOOTP server available:

IPZator – This method listens on the attached network and tries to nd the network address. The netmask is assumed from the network address. It also listens for a free IP address on the network. The gateway address and DNS address are left intact. Please note that it is possible with this method, for the unit to get the same IP address as a piece of equipment that is not active or o. If this occurs, as soon as the other piece of equipment becomes active, the unit will display a network collision error and go o-line.

AutoIP – Automatically assigns a free IP address in the network 169.254.0.0/16. It sets the IP address and the netmask. Gateway address and DNS address are left intact.

The four mentioned methods are cycled through in this order:

t #0051 t %)$1 t *1;BUPS t "VUP*1

Each of the above methods can be disabled by setting a bit in the third eld of the IP address:

“0.0.1.0” to disable AutoIP.

“0.0.2.0” to disable DHCP.

“0.0.4.0” to disable BootP.

“0.0.8.0” to disable IPZator.

Please note that if all bits are set, the unit will no longer discover a network address. To correct this problem, perform a factory reset by pressing the reset button for 10 seconds.

Once connected, the unit can be congured to have a static address by lling in the network parameters on the network page. The parameters are:

Sonic IP – Once the unit has acquired an IP Address, the unit can be congured to read it out over the headphone socket. This is useful if you have a dynamically set IP address as this can change frequently. The IP address is read out every time the unit is reset. This option is enabled as default but can be disabled via the web page.

Advanced Section

While setting up the unit can be a simple process, there are also times when you will have to set up the more advanced features of the products. In this section, we will attempt to demystify the process of setting up the unit and give tips on how to take advantage of all the features. This section assumes a small amount of network and audio knowledge.

PS-SEND

Unit Status

The unit status is available on all pages and contains the following information:

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 Audio 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.

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.

Encoding

Choose one of the pre-selected encoding methods. Then select a sample rate from ‘sample rate’ drop box. Please note that G.711 and PCM have set bit rates while MPEG is variable. The quality drop box only aects MPEG encoding and determines the overall bit rate. If using the digital inputs, MPEG-1 will be used and the sample rate will be detected. The input sample rate is restricted to 32kHz, 44.1 kHz or 48kHz.

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.

Choose how and where the audio data will be sent. Fill in the following details:

Pro Audio Streamers User Handbook

ADVANCED

Connection Type – Select which transmission protocol will be used:

Internet Radio – HTTP single client server. Set IP to 0.0.0.0 to have the server act as a TCP

listener. In this mode port 0 = 80, the default http port. When using this method, a radio path should also be set. More information on the radio path can be found on page 30.

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 specic 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.

SIP – Select SIP for an asterisk SIP server destination. The IP must be set to the SIP server IP. SIP only works when the encoding id set to u or a law 8kHz. See also the SIP user section on page 30. In this mode port 0 = 5060.

Raw UDP – Select raw UDP for a UDP destination. Set IP to 0.0.0.0 to broadcast to the subnet or enter a specic 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.

Port – Fill in the port number which is being used. If this number is set to 0, the default port

number is used.

Advanced Section

The advanced section is spit into six pages which can all be selected via the drop down menu.

Network Settings

IP Address

Enter the IP address as four x three digit numbers 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 rst three numbers are common to all devices, use 255.255.255.0.

Pro Audio Streamers User Handbook

Select which GPI controls the send operation.

Active Open/Closed

Select whether an open or closed state on the selected GPI is used to activate the send operation.

Send Contact Closure Information

If sending using GPI/O and using the RTP transport protocol, the closure of the selected GPI on the PS-SEND can be sent to the receiving PS-PLAY or PS-AMP unit, and the relay contacts on that unit are closed.

Pro Audio Streamers User Handbook

ADVANCED

Trigger Level

When sending using a trigger level, this is the level which will trigger the send.

Pre-trigger Start

Send a stream from an earlier point than that detected by the trigger. Dene an amount of time in msecs.

Post-trigger Play

Send a stream from a later point than the detected trigger. Dene an amount of time in msecs.

Buer Under Run Mode

This denes what happens when a TCP stream is slower than the real stream from the encoder. Once the buer 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 denes 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 lled 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/ SIP User

The Icy-URL is taken into account for shoutcast only. Enter the URL of the web radio station.

SIP user is the user name that will be called on the target SIP device.

Icy-Genre

Genre of the streamed music. Used only on Shoutcast source stream.

Shoutcast Stream

Select if the stream is private or public. Used only on shoutcast source stream.

Type Of Service/DSCP

Implemented in Ipv4, the TOS eld exists in the header and determines how the datagrams are handled. The eld 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

Pro Audio Streamers User Handbook

ADVANCED

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 or Dierentiated Service Code Point is another method for classifying and managing network trac on IP networks. This is also six bits and is a newer alternative to the TOS bits. Diserv aware routers use Per-Hop Behaviours which dene the packet forwarding properties associated with each class of trac. The Per-Hop Behaviour is determined by the DS eld in Ipv4 or Ipv6 header. The behaviour can be either:

Default – Typically best-eort trac. Set to 000000.

Expedited Forwarding – dedicated to low-loss, low-latency. Set to 101110.

Assured Forwarding – Assured delivery under prescribed conditions:

Class 1 Class 2 Class 3 Class 4

Low Drop AF11 (DSCP 10) AF21 (DSCP 18) AF31 (DSCP 26) AF41 (DSCP 34)

Med Drop AF12 (DSCP 12) AF22 (DSCP 20) AF32 (DSCP 28) AF42 (DSCP 36)

The device can save up to three les on the USB drive. If shue is turned on, then a le called “shue.txt” will be saved on to the device. If this le ID is present on the disk, the content will always shue.

Pro Audio Streamers User Handbook

ADVANCED

If there is no play list present or the wrong name is specied in the URL, and the unit has autoplay congured, the device will add an __extr.m3u le and a shue.txt le. The play list will contain a list of all suitable les on the drive and will be played.

The current position in a play list will also be stored in a le called plist.id. The device also stores the USB serial ID in memory. If the device is restarted, the serial ID of the currently inserted USB will be checked against the stored one, and the plist.id will be used if it matches. If the id doesn’t match, the play list will start from the beginning again. If the device is restarted without a USB drive, the stored serial ID is wiped.

Other Play List Types

To use the content from other play lists, such as .asx or .pls simply open them with notepad, cut the http URL and paste them into the URL boxes.

For example, a .pls le may read:

[play list]

numberofentries=4

File1=http://host.com:8068/

File2=http://host1.com:8068/

File3=http://host2.com:8068/

File4=http://host3.com:8068/

In this scenario you could cut http://host.com:8068 into URL1, http://host1.com:8068 into URL2 and so on.

A .asx le may read:

<ENTRY>

</ENTRY>

</ASX>

In this scenario again, just cut the http:/host.com:15634 into a URL on the PS-PLAY web page.

Some radio websites provide a winamp stream le which will typically be in the form of a .pls le. Download the le and edit as necessary.

Http://URL Syntax

To play an mp3 or wma le using the HTTP protocol:

“http://host.com/path/song.ext”

Authentication is also supported. In this case:

“http://user:password@host.com:port/path/song.ext”

RTP:// and BRTP://URL syntax

Theses protocols support mp3 streams in the form:

“rtp://host.com:port”

“brtp://host.com:port”

BRTP is similar to the RTP protocol but modied so that listening to streams is possible from behind a rewall or NAT. With BRTP there is no need to recongure the rewall or device.

In RTP, the address eld can be used in two ways:

Enter 0.0.0.0 to be able to receive a stream from any other IP on the same port.

Enter a specic address to be able to receive streams only from that address.

File:// URL syntax

To play audio from the USB device, use paths and song titles:

“le://folder/song.ext”

The protocol can be omitted for this however, as if there is no protocol in the URL eld. File:// is assumed.

File names and directory names can be up to 255 characters long and must only be of the Western European character set.

Volume

Use this drop down box to alter the volume. The volume is set in 5% increments.

Bass

Alter the amount of bass in a stream. Set between 10 and -10.

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 rst 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 nd out the DNS address. An alternative is needed just in case the rst 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 eld is empty a name will be generated based on the mac address. This enables the devices IP to be identied 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 ltering and can cache responses, meaning subsequent requests for the same content can be sent directly. The PSPLAY 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 les being played from USB behave dierently.

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 buer size (64kB).

USB Backup

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

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 serverbased 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.

On Reconnect Play the...

Choose whether the play list starts from the same song or the next song after an interruption.

Play List Fails

If playing from a play list, the URL can be set to fail if one item in the list fails or if the all the items in the play list fail.
