The Johansson 6712 Profino Revolution SAT is a light-version digital programmable filter amplifier and signal combiner for antenna head-end installations. It accepts five signal inputs simultaneously — one satellite (950–2400 MHz), one FM (88–108 MHz), one DAB/VHF (174–240 MHz) and two UHF (470–862 MHz) — and processes up to 20 terrestrial and satellite channels. Adjacent-channel selectivity is 50 dB, among the sharpest filters available, ensuring neighbouring channels do not cause interference. Channel conversion is not possible in this model.

Each individual multiplex receives real-time AGC, so output levels are automatically stabilised regardless of input variations. The Flex matrix allows filters from any input to be assigned freely across the output, giving complete flexibility in channel planning. The unit is made in Europe and features automatic LTE protection with selectable cut-off at 694 MHz, 790 MHz or OFF. A –30 dB test output is provided for level monitoring. Remote powering at 12 V or 24 V is available on the VHF/UHF inputs.

Key Features

• 5 inputs: 1 SAT + 1 FM + 1 DAB/VHF + 2 UHF
• Processes up to 20 channels (terrestrial and satellite)
• Adjacent-channel selectivity: 50 dB — sharpest filters on the market
• Channel conversion: not available in this model
• Real-time AGC on all individual multiplexes
• Flex matrix: complete flexibility in assigning filters from any input to the output
• Automatic LTE protection: selectable at 694 MHz, 790 MHz or OFF
• 1 main output (SAT-FM-DAB-VHF-UHF) + 1 test port (–30 dB)
• Remote power on VHF/UHF inputs: 12 V or 24 V (100 mA total for 3 inputs)
• ESD protection on all inputs
• Made in Europe

Product Benefits

• 50 dB adjacent-channel selectivity suppresses interference from neighbouring channels, enabling use of adjacent frequencies that weaker filters cannot separate
• Real-time AGC keeps output levels stable automatically, eliminating the need to readjust after seasonal signal-level changes
• The Flex matrix makes it straightforward to remap channel assignments from any input to the combined output without rewiring
• LTE protection at three selectable points (694/790 MHz or OFF) adapts to local spectrum refarming without hardware changes
• The –30 dB test port allows level monitoring during commissioning without disturbing the main output
