VQP HDMI to RF Modulator — HDMI/CVBS to Coax Converter

The VQP HDM69 HDMI to RF Modulator converts HDMI or CVBS RCA signals into VHF/UHF coaxial RF output compatible with PAL and NTSC televisions.

This compact VQP converter takes digital or analog AV sources and produces an RF signal across 47–868 MHz so legacy TVs, distribution amplifiers, or coax runs can receive content without an HDMI input. It accepts HDMI (up to 1080p) and CVBS RCA inputs, outputs via F-type female connectors, supports multiple broadcast bandwidths (6/7/8 MHz), and includes simple AV level adjustment — all in a small ABS/metal chassis powered by AC 90–240V.

How will this device let me send HDMI content to older TVs?

The HDM69 modulates a modern HDMI or composite source into standard RF channels in either PAL or NTSC format, so televisions with only coaxial inputs can display the signal. It handles common resolutions up to 1080p and maps audio into the chosen RF sound system.

• Accepts HDMI and CVBS RCA inputs for flexible sources
• Outputs as RF via female F-type connector for coax feeds
• Supports PAL and NTSC TV formats and multiple audio standards
• Resolutions supported: 1080P/1080i/720P/576P/576i/480p

Which frequencies, bandwidths, and standards does it support?

The unit covers a wide frequency range (47–868 MHz), suitable for both VHF and UHF channel assignments, and offers selectable bandwidths to match regional broadcast spacing. Sound subcarrier offsets are available for common broadcast systems to ensure sync with receiver expectations.

• Frequency response: 47–868 MHz (VHF and UHF)
• Bandwidth options: 6 MHz, 7 MHz, 8 MHz for regional compatibility
• Sound system settings: M, B/G, I, D/K to match TV expectations
• Output level: 90 dBuV minimum, with AV output level adjustment

What connections, controls, and physical details should I expect?

The HDM69 provides HDMI and RCA inputs plus F-type female RF in/out, housed in a small, durable enclosure. It requires no driver installation and runs from an AC 90–240V supply; typical operating temperatures keep it stable in home or commercial AV settings.

• Inputs: HDMI (1.3, HDCP 1.3) and CVBS RCA composite
• RF connectors: F-type female for coaxial in/out
• Power: AC 90–240V; operating temp 0°C–40°C
• Size and weight: 6.1 x 4.1 x 2.1 in; 0.71 lb — compact and portable

How do I set it up and what can I adjust?

Setup is straightforward: connect your HDMI or RCA source, attach coax to the F female RF output, plug in AC power, and choose the TV format plus desired channel/bandwidth. Use the AV output level control to match downstream equipment sensitivity and reduce noise.

• Plug HDMI or RCA source into corresponding input
• Attach coax to RF female output and tune TV to the selected channel
• Select PAL or NTSC and adjust bandwidth/sound system as needed
• Use AV output level to optimize signal strength for receiving equipment

Who is this for: The VQP HDM69 is ideal for installers, retrofitting setups, and homeowners who need to feed modern media players, set-top boxes, or cameras into older TVs or coax distribution networks. It suits small businesses, educators, and AV hobbyists requiring a reliable, no-driver RF conversion solution for PAL/NTSC environments.
