Custom Cables 3.5mm (1/8") TRS to Dual RCA Cable Made from Mogami W2947 & Premium Connectors

Custom Mogami W2947 3.5mm Stereo-to-Dual RCA Breakout Cable

Connect a compatible stereo headphone or analog audio output to a pair of RCA audio inputs while preserving left/right separation. Custom built to order by Performance Audio using Mogami W2947 dual coax cable and premium connectors, this assembly breaks a 3.5mm (1/8") TRS stereo connection out to two RCA mono connections. It is a practical way to bring playback from a suitably equipped laptop, phone, tablet, or other stereo source into compatible mixers, amplifiers, receivers, and playback systems.

Built for Your Connections

• Cable: Mogami W2947 dual coax cable.
• Connection format: One 3.5mm TRS stereo connection to two separate RCA unbalanced mono connections.
• Channel separation: The RCA branches carry left and right separately, not two copies of the same mono signal.
• Connectors: Premium connectors selected from the options available for this build.
• Custom build: Finished cable assembly made to order, not unterminated W2947 bulk cable.
• Identification and finishing: Custom labeling and finishing options available.
• Warranty: Lifetime warranty.

Stereo Breakout, Not Mono Summing

The 3.5mm TRS connection carries left audio on the tip, right audio on the ring, and a shared return on the sleeve. Each RCA branch carries one unbalanced mono channel. Connect the branches to the corresponding left and right analog audio inputs to preserve the stereo image.

This cable does not sum stereo to mono, duplicate a mono source, or provide balanced outputs. Do not join the RCA branches together to combine left and right or connect two active outputs directly together. If you need mono playback, use suitable mixing or summing equipment.

The TRS connector here carries stereo audio, not a balanced mono signal or an insert send/return pair. Confirm the equipment's signal format and wiring rather than relying on connector fit alone.

Check Your Source and Destination

Your source must provide compatible analog stereo audio through a 3.5mm connection. Phones, tablets, and laptops without an analog headphone jack require a compatible audio adapter or interface with analog output; this cable does not connect directly to USB-C or Lightning or convert digital audio. It does not carry a headset microphone signal or headset controls.

Use compatible RCA line-level inputs, such as suitable AUX, line, or playback inputs. Do not connect a headphone or line-level source to phono inputs intended for turntable cartridges. This cable does not provide phono preamplification, equalization, level conversion, or isolation. Start with the source volume and destination gain low, then adjust for a clean signal without clipping.

RCA connectors can also carry coaxial digital audio or video on other equipment. This assembly is for analog stereo audio and does not convert to S/PDIF or video. It is not a speaker cable and must not connect a power amplifier's speaker outputs to passive speakers.

Plan Your Length and Branch Reach

Measure the complete route from the stereo source to both RCA inputs, allowing room for bends, service slack, and connector access. Check how far apart the RCA sockets are and confirm the branch reach needed to connect them without strain. Discuss any special breakout-length requirements with our custom cable specialists before ordering.

Keep unbalanced runs as short as practical and route away from power supplies and AC cabling where possible to help reduce noise pickup. Check clearance around recessed headphone jacks, device cases, and closely spaced RCA sockets when selecting connectors.

Custom Labels and Handling

Ask about left/right labels, destination labels, and available connector color-coding or finishing options to make setup easier. Support the cable so the small 3.5mm socket does not carry its weight, and avoid pulling on the source device or straining the breakout. Disconnect by the connector body rather than the cable, and test both channels before putting the setup into service.

Customization Help

If the website's configuration options do not cover your needs, call or email Performance Audio's custom cable specialists. Provide your source and destination equipment models, required cable length, branch reach, connector-clearance needs, and any labeling, finishing, or wiring requests so we can confirm the build details. Confirm pricing and the build timeline before ordering if you have a deadline.
