AUDIO

   · 4 XLR balanced mic inputs (switchable for mic,line and 48V. phantom power) each with independent level control.
   · 5th line level input called ‘international sound’, which can be routed to any of the monitoring outputs.
   · Remote control of line/mic level inputs.
   · Channel assignament (main or talkback) buttons for each input.
   · Input level indicator for program channel.
   · Limiter after program mixer input.
   · Tree 6.35mm jack headphone outputs with independent channel (local/return) and level controls. The headphone mix      funtion let users monitor local, return audio or a mix of the two for both, the main program and the talkback program.
   · Two XLR male, electronically balanced outputs, as auxiliary outputs. These outputs are totally configurable, so that      each one can be assigned to monitor send, receive audio or a mix of them, for both the main and the talkback      program.
   · The various monitoring signals on headphone and auxiliary outputs can be set by web-interface.
   · Configuration presets: The whole audio output configuration can be stored in different presets.


ENCODING

   · Many industry-standard compression modes: G711, G722, MPEG 1/2 Layer II/III, MPEG AAC LC/LD & HE,      Apt-X standard and enhanced, and PCM (uncompressed linear audio) for IP networks of sufficient bandwidth.


COMMUNICATIONS

   · Built-in 1-BRI ISDN terminal adapter. S/T and U interfaces. Protocols: EISDN, DMS100, NAT1 and AT5ESS.

   · Ethernet 10/100BaseTX interface: Full industry-standard TCP/UDP/IP connectivity. No special      networking required. The following protocols are provided:

           · DNS: Domain Name Server.
           · DHCP: IP address auto configuration.
           · RIP2: Internal/Alias IP addresses can be assigned.
           · SNTP: Clock synchronization.
           · SNMP: Remote monitoring over SNMP protocol.
           · HTTP: An embedded Web server allows the user to monitor/configure the unit from a Web Browser. An ActiveX              dynamic Web Page offers full real time monitoring.
           · IGMP: This protocol deals with Multicast traffic.
           · ICMP: IP control protocol.
           · SMTP: Simple Mail Transfer Protocol.
           · IP Compatibility: SIP/SDP/RTP accoding to the standard for IP compatibility defined by the N/ACIP project within              the EBU group.

Portanet supports Uunicast, Multicast and Multi-Unicast IP audio streaming connections.

   · Prodys Real time Network Analyzer to monitor critical network parameters in real time during the connection.

   · FEC (Forward Error Correction) is supported as per the RFC 2733 standard.

   · Prodys NAT Traversal Streaming Protocol (v3) permits router firewall pass-through with zero coniguration.

   · Streaming advance features:

     · Jitter correction buffer. This adjustable buffer avoids audio dropouts compensating for up to 10 seconds of jitter       in the IP connection.

     · The unit automatically adjusts in synchronisation with the transmitter site rate, to give a constant delay in IP       communications.

     · The frame size is user configurable, to give full flexibility when adjusting the delay and bandwidth use.

     · The codec provides a test tool which allows the user to check the bandwidth, delay and jitter in the IP      connection. This information can be used to adjust the streaming parameters and so, to obtain the best-quality in the      real-time audio reception.

     · Local or remotely (TCP/IP) upgrading of one or several units at once using the same utility, which is      also compatible with ProntoNet units. Factory sofware updates can be downloaded


AUXILIARY DATA

· One RS232 Ancillaty Data port, for data transmission, such as RDS.


GPIO

· 2-GPIOs gives the possibility to connect to automation systems: Remote contact closure to send control signal with the   compressed bit stream.


ALARMS

· Real Time alarms management through SNMP traps and e-mails.
  The alarms are saved in non-volatile memory. It is possible to have an historical log of events even if the unit was   disconnected from the network.


BACKUP

· Integral backup feature to assure program continuity, in the event of a failure of the main line. ISDN   can   be used as a back line line in the event of a failure of the IP line.
