Audio to IP Streaming Encoder
The PS-SEND-SD is a freestanding audio to IP converter which is also available in a 1U rack-mount as the PS-SENDS-SD. 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-SD has a versatile range of functions. It can encode audio from various sources, whether they are analog or digital inputs. Specifically, it supports MP3 encoding, which is available for both analog and digital inputs. Additionally, it can handle G.711 or PCM encoding, but please note that this option is for analog inputs only.
When it comes to transmitting the encoded audio streams, the PS-SEND-SD offers multiple protocol options. You can choose between HTTP, RTP, raw UDP, or raw TCP protocols, making it adaptable to various network setups. Moreover, it includes multicast support, enhancing its flexibility for broadcasting purposes.
The PS-SEND-SD doesn’t just offer encoding versatility; it also provides a range of encoder types to suit your specific needs. These include Mpeg1 & 2 Layer3, MP3 CBR (constant bit-rate), PCM linear, A-law, and U-law. You can configure these encoder types to achieve the desired audio output.
Lastly, the PS-SEND-SD supports a wide range of sample rates, from 8kHz to 48kHz. This flexibility in sample rates ensures compatibility with different audio sources and applications, allowing you to tailor the device’s settings to your exact requirements.
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 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” (6.35 mm) 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-SD 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.
