Compact UHF signal amplifier and RF modulator that converts three RCA CVBS inputs into a coaxial RF output for use with legacy televisions. It accepts line-level composite video and analog stereo audio, making it ideal for devices such as ROKU TV Stick, satellite set-top / cable boxes, PS3, PS4, PS5, Xbox 360/One, Nintendo Switch, DVD/Blu-ray players, VCR, STB, cameras and other A/V sources. The unit can output 3 different TV channels at the same time and features adjustable audio volume and video brightness. Compatible with NTSC TV formats, this modulator covers UHF operating frequencies up to 136 channels (full band) and provides 4 modulated TV channels selectable via a digital channel display and switch. Plug-and-play operation requires no drivers or extra adapters — simple setup saves you from costly local CATV changes. Hardware includes one F-type female coax input for connecting a TV tuner or satellite set-top / cable box, plus a separate RF coaxial output to feed a TV or an RF splitter for distribution to additional sets. The built-in channel switch is designed not to interfere with existing players such as VCRs; channels are programmed with pushbutton digital controls. Also compatible with da-8200 and da-550 Series distribution modulators.
