Monoprice 138080 1-Male to 2-Female RCA Y-Adapter 0.3048m Black Onix Series

Monoprice 138080 RCA Y-Adapter

The Monoprice 138080 is a one-foot RCA Y-adapter that splits a single male RCA output into two female RCA inputs. It is built for stereo audio signals from sources such as CD players, turntables or analogue media devices feeding an amplifier, AV receiver or dual-channel LFE subwoofer. Gold-plated connectors and 97 percent pure oxygen-free copper conductors aim to preserve signal quality. The CL2-rated jacket is cleared for in-wall residential installation.

Splitter limits and shielding

This adapter is designed only to divide a line-level signal; it cannot combine two sources into one input without risking impedance mismatch or signal loss. Double copper braid shielding protects the 0.3048-metre run from EMI and RFI interference that can degrade audio fidelity. The braided nylon outer sleeve adds abrasion resistance while keeping the cable flexible for tight routing behind equipment racks or through wall cavities.

Check your connections before ordering

Verify that your source device provides a single female RCA jack and that each destination device accepts a male RCA plug. Confirm the required cable reach; the fixed 0.3048-metre length offers no slack for widely spaced components. Ensure you need a splitter rather than a combiner, as this unit does not sum stereo channels to mono or merge two outputs into one.
