Audio cable Unitek C19026BK01 — 2× RCA (CINCH) to 3.5 mm TRS jack, 20 m

The Unitek C19026BK01 is a 20-metre audio cable that provides a stereo connection from two RCA (CINCH) outputs to a single 3.5 mm TRS jack. It is intended for transmitting analog line-level stereo signals over long distances and is suitable for linking CD players, mixers, audio interfaces and other consumer or pro-audio sources to speakers, amplifiers, monitors or portable devices with a 3.5 mm input.

Advantages

This 2× RCA to 3.5 mm TRS cable offers a long 20 m length to accommodate installations where sources and inputs are far apart. The cable supports standard stereo line-level signals and simplifies connectivity by combining left and right RCA channels into a single 3.5 mm TRS plug. Its construction is aimed at maintaining a consistent analog signal across the run, reducing the need for additional adapters or converters.

Suitable for

• Connecting CD players, media players or audio interfaces to devices with a 3.5 mm stereo input
• Linking mixers or DJ equipment to portable recorders or consumer amplifiers
• Home audio setups that require a long analog stereo cable run
• Temporary or semi-permanent audio installations in small venues, rehearsal rooms or classrooms

When it may not be suitable

This cable is intended for analog line-level stereo signals and is not suitable for balanced microphone-level connections or professional balanced TRS runs. It does not provide digital audio transmission, nor does it convert signal levels or impedance; using it with incompatible equipment may result in low volume, noise, or channel imbalance.

Key specifications

• Cable type: 2× RCA (CINCH) to 3.5 mm TRS stereo
• Length: 20 metres
• Signal: Analog stereo line-level
• Connectors: Dual RCA plugs (left/right) and 3.5 mm TRS male plug
• Intended use: Unbalanced stereo connections for consumer and pro-audio equipment

How to use

Connect the left and right RCA plugs to the corresponding output jacks on the source device, observing left (white) and right (red) channel assignment. Insert the 3.5 mm TRS plug into the stereo input of the target device. Keep cable runs away from mains power cables and sources of electromagnetic interference where possible, and avoid tight bends or kinks to preserve signal integrity. For best results, ensure both source and destination operate at compatible line-level output and input settings.

What to consider before purchase

• Ensure your source device provides unbalanced RCA line-level outputs and the target device accepts a 3.5 mm stereo TRS input
• Verify that a 20 m cable length suits your installation and that run routing can avoid excessive interference
• Confirm that an unbalanced analog cable meets your noise and performance requirements; consider balanced or digital alternatives if needed

Usage recommendations

For reliable results, route the cable away from mains wiring and fluorescent lighting, secure it along surfaces to prevent strain, and check connections for proper channel orientation. If you encounter hum or noise on long runs, test with shorter cables or consider a dedicated balanced cable or direct box to improve noise rejection.
