Professional UHF AV to RF Modulator

A professional-grade UHF RF modulator engineered for reliable AV-to-RF conversion in commercial installations. Built with ABS casing for durability, it accepts PAL or NTSC composite video and stereo audio via RCA female inputs and outputs a clean RF signal via F-type female connector (75Ω impedance). Frequency range spans 471.25–885.25 MHz (UHF Ch 21–69), with precise 85±5 dBuV output level. Audio carrier options include M (4.5 MHz), B/G (5.5 MHz), I (6.0 MHz), and D/K (6.5 MHz), accommodating diverse regional TV standards. DC power (9 VDC/100 mA) is delivered through the RF output port, simplifying wiring. Default setting is Channel 21, PAL-B/G, 38 kHz. User controls include independent adjustment of video and audio output levels, manual frequency tuning with on-device display, and memory storage for frequently used configurations. Designed for seamless integration with TV Link, SLX, and third-party set-top boxes. Ideal for fixed AV distribution in multi-screen venues requiring plug-and-play compatibility with existing coaxial infrastructure. Commonly deployed in hospitality (hotels, B&Bs), food & beverage (pubs, restaurants, sports bars), retail (supermarkets, convenience stores), and leisure (gym lounges, waiting areas) where cost-effective, low-maintenance RF signal distribution is essential.
