(as of Dec 29,2020 13:50:19 UTC – Details)
This professional RF modulator combines 4 RF modulators into one unit so it can convert and combine 4 composite RCA video/audio inputs to 4 user-defined TV channels at the same time for commercial or educational purpose.
Supports 4 composite RCA video inputs and 4 RCA audio inputs. Easy front panel push button control for easy channel selection. Each video/audio input can be individually set up for different TV channel output. Support RF output in cable channel range from CH58 to CH138 or UHF/VHF channel range from CH14 to CH83 Users can add more of these RF modulators at any time for more video sources to be modulated into more TV channels and combined in same coax cable run for distribution.
Transmitting audio/video over coax cable offers greater transmission range and much lower cost than the typical balun or Cat5 extender solution. Must-have A/V adapter for combining both RCA video/audio from device into RF type for long range video/audio distribution. Cost saving with source device sharing. All TVs connected through the same coax cable can share the same video source. Video and audio signals from CCTV surveillance camera can be presented on your TV channels.
Powerful 100db signal output sufficient for long cable runs up to 1200 meters. Multiple of these 4-input RF modulator units can be cascaded together to distribute more video feeds to more TVs in the same coax cable run. Last memory support for keeping user’s last-minute setting intact after being powered off manually or power outage event.
