RCA Y-Splitter Cable - 1 Female to 2 Male RCA Adapter (20cm)

Prototyping and Engineering Tips from Robogears

• Subwoofer Optimization: Many active subwoofers have "Left" and "Right" inputs but your receiver might only have one "Sub Out." Using this Y-splitter to feed both inputs can often increase the input sensitivity (gain) of the subwoofer by about 3dB.

• The "Mono-to-Stereo" Illusion: Note that this cable does not create a true stereo signal; it merely duplicates a mono signal into two identical paths. If you are using this to connect a mono source to a stereo system, both speakers will play the exact same audio.

• Avoid "Daisy-Chaining": Do not use multiple splitters in a row to feed four or eight devices from one source. Each split slightly reduces the signal voltage (amplitude), which can lead to a lower volume or increased background hiss (noise floor).

• Connector Care: When plugging or unplugging, always grip the molded plastic housing. Never pull on the 20cm wire itself, as this can strain the internal solder joints and lead to intermittent audio "popping."

Package Includes

• 1 x 1 RCA Female to 2 RCA Male Y-Splitter Cable (0.2m)

Disclaimer: This cable is designed for low-level analog audio signals. Do not use it for digital COAXIAL signals or high-power speaker-level outputs, as the impedance and shielding are not optimized for those specific applications.
