Compact 4-Port Audio Switch

The Cubilux bidirectional selector routes stereo signals between four 3.5 mm ports and a single 3.5 mm port, or the reverse, with a simple rotary knob. No drivers or external power are required, and the aluminium enclosure shields the signal from electrical interference. Non-slip silicone feet keep the unit stable on a desk.

Suited for multi-device stereo setups

Users who want to compare headphones, swap between speakers, or share one source across several outputs will find the four-channel switching convenient. The device handles only line-level stereo audio, so anyone needing microphone pass-through, mono summing, or digital audio formats should consider a different solution.

Four stereo ports on 3.5 mm jacks

The selector provides four female 3.5 mm connections on one side and one female 3.5 mm connection on the other, enabling 1-in/4-out or 4-in/1-out operation. All switching is passive and bidirectional, preserving the analogue signal without conversion or amplification.

Questions about this item

Should I pick the 3.5 mm or 6.35 mm ports for my headphones?

Use the 3.5 mm female ports for standard headphones or earphones; the 6.35 mm female ports are for larger studio-style plugs. Both sets are available on the same switch.

Does the knob introduce any audible noise or signal loss?

The aluminium alloy housing isolates interference and the passive design transmits the stereo signal without added static or ground noise.

What does the bidirectional 3.5 mm switch actually let me do?

You can route one source to any of four outputs, or select one of four sources to a single output, all with a single twist and no driver or power supply needed.
