Distribute one STB or DVD signal to a few rooms using your existing home wiring while maintaining global compatibility and reliable reception. Key benefits Share a single set box (STB) or DVD player with a few rooms without extra boxes or complex wiring, reducing equipment cost and clutter. Global TV format compatibility (PAL/NTSC) and adjustable Sound IF let the device work with receivers from different regions, so visitors or imported equipment will function correctly. Wide, selectable frequency range (471.25 MHz–885.25 MHz) with correspondence frequency display and builtin memory reduces the chance of interference and simplifies channel matching. Uses the existing circuit in a typical home, avoiding the need for cabling or structural changes and enabling fast, lowdisruption installation. Main functions and attributes Function: Transmits an audio/video signal from one STB or DVD source to multiple rooms. Compatibility: Supports PAL and NTSC video formats and adjustable Sound IF to match various TV/receiver standards. Frequency and performance: Operates across 471.25 MHz–885.25 MHz. Selectable transmitting frequency, an ondevice correspondence frequency display, and builtin memory help prevent and mitigate interference from other signals. Installation: Designed to work with the general household circuit; no specialized wiring required. Reliability: Builtin memory stores preferred settings, easing reuse and minimizing setup time while preserving interferencereduction settings. Practical use scenarios Home multiroom viewing: Send your livingroom STB signal to a bedroom and a guest room so two or three rooms can watch the same source without buying extra players. International equipment compatibility: Use with TVs or receivers from different regions by switching between PAL and NTSC and adjusting Sound IF for correct audio/video decoding. Shortterm setups or rentals: Quickly provide a single DVD or STB feed to several rooms in guest accommodations or temporary living spaces using the home's existing wiring. What it solves Eliminates the need for duplicate source devices in multiple rooms. Avoids expensive rewiring by using current home circuitry. Reduces signal conflicts through selectable frequencies, frequency display, and memorystored settings. Ensures playback compatibility for different international TV standards and audio IF requirements.
