Intercom Base Station
IBS
The IBS is SVP Aerospace´s intercom base station. Installed in the OB Van, it allows the TV producer to run a live show and communicate with the different technicians that take part on it.
The intercom base station has an integrated duplexer. It can work in full-duplex mode allowing the technicians and operators to communicate with the TV producer. It has 25 W output power and can work in continuous cycle without limit in time. It works in the UHF band and a very wide coverage is achieved.
Main features:
• Frequency band: 440 to 470 MHz (UHF)
• Duplex channel number: 16
• Output power: 25 W (100% duty cycle)
• Integrated duplexer
• Power supply: 13.2 VDC
• PTT switch (for continuous operation)
