Portable Audio Codec for IP, 3G/3.5G and ISDN with 4 audio inputs.

AUDIO

•Inbuilt channel mixer for both input and output sources

◦4 Mic/Line inputs with phantom power.

◦1 Line input (International Sound Input).

◦4 headphone outputs & 2 auxiliary line outputs.

•Compressor/limiter for Program Channel.

•Remote control of levels and signals (I/O matrix).

•Supports Mpeg1/2 LayerII/III, AAC, apt-X, G711/G722 and PCM.

•The various signals to monitor on the headphone and the auxiliary outputs can be set by web-interface.




COMMUNICATIONS

•IP, 3G/3.5G (optional), PSTN and ISDN communications.

•Nomada IP W offers fully TCP/UDP/IP connectivity via an Ethernet port.

•IP Multicast, Unicast and Multi-Unicast audio streaming transmission/reception.

•Buit-in ISDN terminal adaptor with S/T and U interfaces.

•Dual operation over IP and ISDN: Program and Talkback lines.

•BackUp System: ISDN as a secondary link for IP.

•IP Compatibility: SIP/SAP/SDP/RTP/STUN protocols are supported according to the standard defined by the N/ACIP project within the EBU group.

•Prodys NAT Traversal Streaming Protocol permits router firewall pass-through with zero configuration.

•FEC (Forward Error Correction). Up to 24 different schemes are available, to fit to the desired delay and available bandwidth.

•Error Concealment mechanisms on Mpeg audio modes are supported to reduce the impact of packet losses.

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

•Streaming advance features:
- Automatic Jitter buffer. This adjustable buffer avoids audio dropouts compensating for up to 10 seconds of jitter in the IP connection.
- Automatic synchronization adjustment with the transmitter site rate, to give a constant delay in IP communications.
- User configurable frame size, to give full flexibility when adjusting the delay and bandwidth use.
- Test tools 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. Factory software upgrades can be downloaded.


OPERATION

•The unit can be controlled locally from its front panel, or remotely from its Web Page or from ProdysControl.

•Automatic detection of the encoding mode used by the remote unit.

•Independent encoding/decoding operation.

•Call facilities: Auto-redial, call scheduler and log systems.

•User Access Control to define different access restrictions in a per user basis.

•Configuration presets to define different configurations for all or some specific parameters.

•Alarms: Real Time alarms management through SNMP traps, GPO and e-mails

•Serial port to transmit/receive ancillary data along with the audio.

•GPIO port: 2 inputs/outputs. User configurable with multiple functions such as remote contact closures.

•Optional battery with charge and status indications. It can be charged on system.
