HDMI to RF Modulator, HDM61 HDMI to NTSC Format Output CH3 CH4, 1080P PLL Control for Home TV Game Console

Description: Transform your modern HDMI sources into classic analog TV signals with the HDM61 HDMI to Coax RF Modulator. Designed for NTSC analog televisions with RF-only inputs, this converter lets you enjoy streaming sticks, DVD players, game consoles, and more on vintage screens without complicated setups. Simply plug in your HDMI device, select channel 3 or 4, and watch your content on any standard-definition TV via a standard coaxial cable. Equipped with dedicated RF input and output F-type connectors, the HDM61 goes beyond simple conversion. You can connect an external antenna and merge over-the-air broadcasts with the modulated HDMI signal, so your old TV maintains full access to local channels while you enjoy modern digital media. This makes it an ideal solution for retro gaming setups, hotel TV systems, school AV carts, or church multimedia displays. The modulator supports a wide range of input resolutions, including 1080P, 1080i, 720P, 576P, 576i, and 480P, and uses PLL frequency control to lock VHF channels accurately at 61.25MH z (CH3) or 67.25MH z (CH4). With an output level of 805dBuV and M-standard 4.5MH z audio, it provides stable, clear video and sound to any NTSC analog television.

The compact, durable ABS housing protects internal components for long-lasting reliability, while plug-and-play operation requires zero software or configuration.

User ManualQ&AQ: Why is there only video and no sound?
A: Regarding the HDM61 having video but no sound, the
following issues were found: 1. The customer is using Dolby audio, but our product solution 1836S does not support Dolby audio (because we haven't obtained Dolby's authorization), resulting in video but no sound; 2. The customer's HDMI signal contains signals with HDCP 2.0 or higher, while ours is HDCP 1.4. 2.0 is not backward compatible, so users are required to disable HDCP or downgrade to HDCP 1.4; otherwise, there will be no sound output; 3. Our product's digital DTS transmission supports audio sampling rates of 32K/ 44.1K /48K/ 88.2K /96K/ 176.4K /192K. Audio samples at sampling rates outside this range will also result in no sound output.
Q: Besides channels 3 and 4, do you have other channels?
A: This HDM61 only has channels 3 and 4.
