2-Male to 1-Female RCA Y-Adapter

The Monoprice 138079 Onix Series adapter splits a single line-level RCA audio signal into two channels for left and right speakers or a dual-channel LFE subwoofer. It connects a CD player, record player or analog media device to an AV receiver or amplifier using gold-plated connectors. The one-foot cable uses 97 percent pure oxygen-free copper conductor for signal transmission.

Shielded construction for sustained signal integrity

Double shielding with copper braiding protects the RG-6/U conductor from EMI and RFI interference during continuous use. The braided nylon jacket resists nicks and cuts without reducing flexibility, maintaining performance across long installations. A CL2-rated jacket complies with fire safety regulations for in-wall residential runs.

Check connector gender

Ensure your source device provides a female RCA output and your destination equipment accepts two male RCA plugs for a stereo or LFE split. This adapter handles analog line-level audio only; it does not carry digital coax, video or powered speaker signals. Verify that a one-foot reach suits the distance between your components.

Questions about this item

Does the 1 ft Onix Series Y-adapter add any audible noise or heat when used continuously?

The adapter is a passive copper cable with gold-plated RCA connectors and double copper-braid shielding, so it draws no power and generates no heat or noise during all-day use.

What equipment must I already have to use the 138079 Y-adapter?

You need a source device with a single female RCA output (such as a CD player, turntable or AV receiver subwoofer output) and two male RCA cables to connect the adapter's female end to your amplifier or powered speakers.

Will the 0.3048 m Onix Series cable work reliably with older RCA gear that uses standard unshielded leads?

Yes, the 97 % oxygen-free copper conductor and double shielding maintain signal integrity when bridging legacy unshielded RCA equipment to modern components.
