Multi-channel Filter Amplifier: Johansson PROFINO Revolution 6711 (FM-DAB/VHF-2xUHF, digitally programmed)

The PROFINO Revolution 6711 programmable amplifier is designed for shared DVB-T/T2 antenna installations (S/MATV systems) in multi-family residential buildings, residences, hotels, guest houses, holiday homes, schools, hospitals, etc.

The amplifier is dedicated for antenna systems in places with difficult reception conditions, especially where terrestrial TV signals received by antennas come from different directions and have very varied levels. The device has two programmable inputs for signals in UHF band (470-862 MHz), one input for DAB/VHF (174-240 MHz) band and one FM input (88-108 MHz), and can process 30 channels. The use of the filter amplifier allows for selective amplification of the various channels in order to equalize them. The automatic gain control (AGC) implemented in the device can balance the output signals levels despite major differences at the inputs (on the condition that the parameters of each channel are above the minimum values). The installer can freely configure the DAB/VHF and UHF inputs and optimize individual channel levels just on site, in order to provide high quality images on TV screens. PROFINO Revolution 6711 can be used as a standalone device in MATV and SMATV systems (e.g. based on multiswitches) or as a component of headends.

The device can provide power for antenna preamplifiers via its VHF/UHF inputs (12 or 24 VDC, max load of all inputs 100 mA).

LTE filter options ensure resistance to interference from LTE networks operating in 4G (>790 MHz) and 5G (>694 MHz) technology.

The amplifier can only be installed indoors.
