Audio cable Unitek C19024BK01 — 2× RCA (Cinch) to 3.5mm TRS jack, 10 m

Unitek C19024BK01 is a 10‑metre audio cable that converts a stereo pair of RCA (Cinch) connectors to a 3.5 mm TRS jack. It is intended for analog audio connections where a long reach is required, such as linking stereo outputs with RCA sockets to devices that accept a 3.5 mm headphone‑style input. The cable provides a simple solution for home audio systems, portable players, laptops and recording setups that need a single stereo lead instead of multiple adapters.

Advantages

The cable offers a 10 m length that allows flexible device placement without the need to relocate equipment. Its dual RCA to 3.5 mm TRS configuration supports standard stereo connections and enables direct transfer of left and right channels. The product’s design emphasises straightforward, passive signal transmission with familiar connector types that are widely compatible across consumer audio devices.

Suitable for

• Connecting stereo RCA outputs from amplifiers, CD players or receivers to a 3.5 mm input on laptops, portable recorders or soundcards
• Temporary or semi‑permanent home audio installations where a long analog cable run is needed
• Desktop recording or playback setups that require a single stereo connection between devices

When it may not be suitable

This cable carries an unbalanced analog signal and is not intended for professional multi‑channel installations that require balanced connections or XLR/TS cabling. For long runs in electrically noisy environments, unbalanced RCA/3.5 mm wiring can be more susceptible to interference compared with balanced alternatives.

Key specifications

• Cable length: 10 metres
• Connector types: 2× RCA (Cinch) to 3.5 mm TRS jack
• Signal type: Analog stereo (unbalanced)
• Intended use: Line‑level audio connections between consumer devices

How to use

Connect the two RCA plugs to the left and right output jacks of the source device, matching colours or channel labels where present. Insert the 3.5 mm TRS plug into the line‑in or headphone‑style input of the destination device. Set source and destination volume levels to a low or moderate setting before playback, then adjust levels to the desired listening or recording volume. Unplug by gripping the connector bodies rather than pulling the cable to avoid strain on the terminations.

What to consider before purchase

• Verify that the destination device accepts a 3.5 mm TRS stereo input (not a microphone‑only CTIA/OMTP headset jack with combined functions)
• Confirm that an unbalanced analog connection is suitable for your environment and signal‑quality requirements
• Ensure 10 m is an appropriate length for your setup to avoid excess cable slack or signal loss concerns

Usage recommendations

For best results, route the cable away from mains power lines and large transformers to reduce hum and interference. Use secure connector seating at both ends and avoid tight bends to preserve signal integrity over the full 10 m length.
