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.
Any standard composite RCA video audio feeds from devices such as satellite receivers, cable box, DVD player or surveillance camera can be modulated by this device into a new private TV channel of user’s choice for distribution or merged with existing CATV system.
After finishing the cable hookup, simply use the push buttons on the front panel to choose an unused or unwanted TV channel number for CATV system or UHF/VHF system use.
Next use TV remote to tune into the new TV channel and shall see your DVD or camera video on TV screen.
4 RCA Video/Audio Inputs
This RF modulator supports total of 4 composite RCA video inputs and 4 audio input. Each video/audio input can be individually set up for different TV channel output.
Air/CATV Frequency Support
Support RF output in cable channel range from CH58 to CH138 or UHF/VHF channel range from CH14 to CH83.
This 4-input RF modulator allows user to create up to 4 private TV channels for school, community, church or conference room.
3 of these modulators can create total of 12 private TV channels.
Video Audio Extension Over Coax Cable
This RF modulator can also be combined with our RFDM2 or RFDM250 TV tuner as a video/audio over coax cable extender kit.
100db Output For Long Range Transmission
This RF modulator has a powerful 100dB output, sufficient for long cable transmission up to 1200 meters with no loss.
Professional-grade audio/video to RF modulator for broadband A/V distribution for all NTSC TV system setup. Converts up to 4 composite RCA video/audio inputs to 4 user-defined CATV or UHF channels in one cable run to all TVs. Cost-saving solution for building private MATV or closed-circuit TV system. A great analog TV channel modulator for distributing up to 4 live video from SD sources such as cable box, DVD player, signage player, etc, and broadcast the modulated videos on a new or existing ca
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.
