- Main Features:
- Cost-effective solution with essential features, and no compromises on reliability
- Adapted to legacy audio infrastructures and full-IP audio infrastructures
- EBU/ACIP compliance for interoperability with third-party codecs and any SIP infrastructure
- Multiple levels of redundancy for audio service continuity and failsafe operation: 2 power supply units, 4 network ports with stream redundancy, audio failovers, audio hardware by-pass, and 1+1 hot device redundancy
- Control and configuration via SNMP and Web services for easy integration with codec and network management/monitoring systems
- Specifications:
- I/Os and POWER:
- 2 balanced analog audio I/Os with 24 bit converters, and 1 stereo AES/EBU
- I/O with hardware sample rate converter, and 2 AES67 or Ravenna or Livewire I/Os
- 4 ethernet ports: 1x100Mbps + 3x1Gbps on RJ-45 connectors
- 1 RS232 port for serial data tunneling
- 8 GPI / 8 GPO on Sub-D25 connector
- 2 internal redundant PSUs 100-250VAC (Optional 100-250VAC / -48VDC) (Max 15W consumption)
- NETWORKING:
- RTP/UDP, Icecast/Shoutcast, HLS, SIP/SDP, STUN
- PTP, NTP
- DHCP, IGMPv2 and v3, QoS (VLAN tagging, DSCP)
- SNMP, HTTP
- ENCODING, DECODING AND STREAM PROTECTION:
- Audio encoding formats: PCM linear 16/20/24 bits, ISO MPEG-½ La yer II and Layer III, MPEG-4 AAC-LC, AAC-LD, HE-AACv1, HE-AACv2, AAC-ELD, Opus
- Selectable FECs for ACIP/RTP streams (from +10% to +100% IP bandwidth) Pro-MPEG CoP #3 FEC for MPEG-TS streams
- Dual port redundant streaming with spatial and time diversity
- Adaptive and resilient audio streaming (Fluid-IP)
- FUNCTIONS
- Multi-format encoding of the audio sources Network traffic separation (WAN, LAN, Management)
- Configuration and monitoring via intuitive Web GUI and via SNMP
- Optional: Simultaneous multi-protocol streaming
- Optional: Audio output synchronization of decoders based on NTP or PTP
- Available clock synchronization are internal, AES/EBU inputs, PTP, livewire clock
- Hardware by-pass of the audio inputs to the audio outputs (analog and AES/EBU)
- Unicast, multi-unicast, multicast, multi-multicast addressing
- 3 decoding priorities per output program with choice of the audio source on each priority: IP stream, playlists on SDHC card, or audio inputs.
- The switch between decoding priorities is automatic according to adjustable criteria
- Silence detection on the audio inputs and on the received IP audio streams
- Place calls from an address book or receive calls for live broadcasts (SIP, Direct SIP, Symmetric RTP)
- Auxiliary data tunneling of physical or IP serial data and GPIs (including RDS-UECP)
- Insertion of metadata to Icecast/Shoutcast streams (yellow pages and on-the-fly)
- Optional: AES transparency without the need of an external GPS synchronized clock
