DAB/DAB+/T-DMB Transmitter- ADRIA
OVERVIEW
ECRESO offers a full range of transmitters dedicated to the distribution of DAB, DAB+ and T-DMB digital broadcasting. These products
operate in VHF (Band III). They comply with the DAB standard as required by ETSI TS 102 428 and ETSI ETS 300 799 for ETI, including video
content. The available power ranges are from 150W to 2.4kW for Band III, and 100W to 800W for L-Band.
FEATURES
• High quality modulator
• Excellent MER, Digital precorrection, very
low phase noise
• Excellent stability
• MFN / SFN functions with multiple
synchronization capabilities (ETI, GPS, …)
• Two ETI inputs (switch-over without
interruption)
• NI or NA input, with autodetect of the type
of signal
• option: dual power supply + UPS
• option: adaptive precorrection
BENEFITS
• 3 years warranty upgradable to 5 years
• Monitoring functions integrated inside the
modulator
• Remote control functions integrated inside
the modulator
• Redundancy
• IP and SNMP standard for excellent network
functionality
• Powerful automation software included to
easily create and manage a dual drive system,
1+1 or N+1
• Integration of monitoring with our Broadcast
Manager server to optimize your monitoring
strategy.
APPLICATIONS
• Used by broadcasters, to transmit or
retransmit DAB, DAB+ or T-DMB on SFN or MFN
networks
