Redukce na rozdíl od prodlužovacích kabelů nejenom zvyšují dosah kabelů, ale umožňují také převod informací mezi různými druhy konektorů. Redukce můžete použít pro vzájemné propojení odlišných video, audio a USB kabelů. S výběrem té správné vám rádi poradíme.

Redukce, nebo převodník?

Pro převod signálu mezi jednotlivými analogovými nebo digitálními rozhraními si vystačíte se základní pasivní redukcí. Pokud ale chcete převést analogový signál na digitální a naopak, budete k tomu potřebovat aktivní převodníky. Jejich nevýhodou ale je vyšší náchylnost na rušení, což může zhoršit kvalitu přenosu.

Audio redukce

Audio redukce slouží pro převod zvukových signálů mezi různými audio konektory. Mezi nejčastěji používané audio rozhraní patří 3.5mm a 2.5mm Jack, Cinch a optické kabely.

i

U telefonů iPhone 7 a vyšších vám přijde vhod i redukce Lightning na Jack, jelikož tyto telefony již samostatným Jack výstupem nedisponují.

Video redukce

Video redukce nejvíce využijete pro propojení televize s různými druhy video přehrávačů. Kromě obrazu mohou přenášet i zvukovou stopu. Nejběžnějšími konektory v této kategorii jsou HDMI, VGA, DisplayPort, DVI a Scart.

Následující rozhraní lze vzájemně propojit i bez potřeby redukce:

  • Různé verze HDMI – například HDMI v1.3 a HDMI v1.4.
  • DisplayPort a Thunderbolt.
  • DVI-A, DVI-D a DVI-I.

USB redukce

USB redukce se používají pro převod dat mezi USB, micro USB a USB-C konektory. Mnohdy obsahují více výstupních konektorů, případně mohou mít i HDMI rozhraní nebo RJ-45 konektor pro síťové připojení.

Bez redukce se obejdete, pokud chcete propojit následující rozhraní:

  • USB 2.0 a USB 3.2 (dříve USB 3.1)
  • USB-C a Thunderbolt.
