Onix Series 3.5 mm to Dual RCA Adapter

The Monoprice 138081 cable connects a 3.5 mm stereo source to two gold-plated RCA male plugs. It uses 97 percent pure oxygen-free copper conductors and double copper-braid shielding to reject EMI and RFI. A braided nylon jacket protects the CL2-rated cable for in-wall residential runs.

Suits portable audio and line-level hookups

This adapter serves phones, tablets, portable mixers or computer sound cards that output line-level stereo through a 3.5 mm TRS jack. It is not for speaker-level amplifier outputs, balanced professional interconnects or digital coaxial signals such as S/PDIF.

Verify source jack and cable route

Confirm your device provides a standard 3.5 mm TRS line-level output rather than a headphone-only or proprietary connector. Check that the 0.9144 metre length reaches between your gear without strain and that CL2 rating meets any local building-code requirements for in-wall installation.

Questions about this item

What source device needs a 3.5 mm TRS output to use this cable?

Any device with a 3.5 mm TRS jack — phone, laptop, portable mixer or computer sound card — can feed line-level audio into the two RCA plugs.

Will the gold-plated RCA ends mate reliably with older RCA inputs on a vintage amplifier?

Yes, the gold-plated RCA male connectors fit standard RCA sockets and resist oxidation, so they work with older gear without signal loss.

How can I verify the cable is passing audio correctly after connecting it?

Play a known track; clear, balanced sound from both channels with no hum or crackle confirms the 97 % oxygen-free copper conductors and double copper braid shielding are working.
