SKU CH-B1N9-4T3C2

Passive RCA switch box routes three stereo inputs to one output or one input to three outputs with gold-plated terminals and a shielded aluminium case

  • Reversible 3-in-1-out or 1-in-3-out routing
  • Gold-plated RCA terminals for clean signal transfer
  • Passive operation requires no external power supply
  • Shielded aluminium chassis blocks external interference

WUQ U31 Passive RCA Switch

The WUQ U31 is a passive RCA switch box offering three inputs and one output, reversible to one input and three outputs. It routes stereo signals without an external power supply. Gold-plated terminals and a solid aluminium chassis provide durable connections and shielding against interference.

Three-Input Selector for One Zone

The single specification that decides fit is the 3-in-1-out topology, which selects one source at a time for a single amplifier or active speaker. It does not drive three zones simultaneously, so buyers needing multi-room distribution must look elsewhere.

Questions about this item

How does the 3-in-1-out switching work when I connect three sources to one amplifier?

The rotary switch selects one of the three RCA inputs and routes it to the single output, so only the chosen source plays through the connected amplifier at any time.

Does the passive design limit the signal quality or cable length I can use?

Because it requires no power and uses gold-plated RCA terminals with a shielded aluminium case, the switch adds no active noise and preserves the original signal level for typical home-audio cable runs.
