Audio cable Unitek C19025BK01 — 2× RCA (Cinch) to 3.5 mm TRS jack, 15 m

The Unitek C19025BK01 is a 15 m audio cable that terminates in two RCA (Cinch) plugs and a single 3.5 mm TRS jack. It is intended to link stereo sources with RCA outputs — such as receivers, CD players or preamplifiers — to devices with a 3.5 mm stereo input like portable speakers, laptops or car auxiliary inputs. The cable's length provides flexibility for room-scale setups, AV furniture placement, and installations where the source and destination are separated by a significant distance.

Advantages

This Unitek audio cable combines standard stereo connectors for broad compatibility and a longer 15 m reach to avoid the need for multiple extension pieces. The two RCA plugs yield a clear left/right channel separation while the 3.5 mm TRS jack fits common mini-jack inputs without adapters. The cable is suitable for analog signal transfer without conversion, maintaining the source's native stereo signal for simple, low-latency audio connections.

Suitable for

• Connecting home AV receivers or CD players with RCA outputs to speakers or devices with a 3.5 mm input
• Wiring portable audio players, smartphones (via line-in), or tablets to stereo systems that accept RCA
• Car audio auxiliary connections when a long run is required between source and input
• Temporary or semi-permanent AV setups where a 15 m analog stereo cable is needed

When it may not be suitable

This cable carries unbalanced analog stereo signals and is not designed for professional balanced audio installations; it may pick up noise over long runs in electrically noisy environments. It does not provide digital conversion, microphone support, or channel mixing — only a direct stereo pass-through between RCA and a 3.5 mm TRS jack.

Key specifications

• Cable length: 15 metres
• Connector configuration: 2× RCA (Cinch) to 1× 3.5 mm TRS jack
• Signal type: Analog stereo (unbalanced)
• Typical use: Line-level audio connections

How to use

Plug the two RCA connectors into the left and right output jacks of the source device, matching colors where provided (usually red = right, white or black = left). Insert the 3.5 mm TRS jack into the stereo line-in or auxiliary input on the destination device. Route the cable to avoid tight bends and prolonged tension; if running near power cables or other sources of electromagnetic interference, maintain separation to reduce potential noise pickup. Test playback at low volume first and adjust source and destination levels to achieve the desired sound without clipping.

What to consider before purchase

• Confirm that the source uses unbalanced RCA outputs and the destination accepts a 3.5 mm stereo TRS input
• Assess whether a 15 m unbalanced analog run is appropriate for your environment (noise and signal loss potential)
• Check physical routing and strain relief needs for the intended installation

Usage recommendations

For best audio quality, keep the cable away from mains power lines and large transformers. Use at moderate volumes and verify source/destination line-level settings to avoid distortion; for long runs in noisy environments, consider balanced cabling or a short active line-level repeater.
