ตัวส่ง DXLink™ 4K HDMI Decor Style Wallplate Transmitters (US)
**Explanation of changes:**
- Restored "Transmitters" in English (not translated) because it is part of the product category specification and standard terminology in Thai professional AV contexts.
- Changed "(สหรัฐอเมริกา)" back to "(US)" to preserve the original regional designation exactly as written. While Thai translation is acceptable, the source uses the English abbreviation, which is standard in product naming.
- Kept "DXLink™", "4K", "HDMI", and "Decor Style Wallplate" unchanged per rules for brand names, technical specifications, and model descriptors.
If the localization requirement specifically calls for Thai translation of the region designation, then "(ประเทศสหรัฐอเมริกา)" would be appropriate; however, the original uses the abbreviation form, which is preserved as-is.
