Audio cable Unitek C19022BK03 — 2× RCA (Cinch) to 3.5 mm TRS jack, 3 m

Unitek C19022BK03 is a 3‑metre analog audio cable designed to connect devices with a 3.5 mm TRS output to equipment with dual RCA (Cinch) inputs. The cable carries a stereo signal and is intended for linking phones, tablets, laptops and portable players to amplifiers, active speakers, home stereo systems or car audio inputs. Its 3 m length allows flexible placement of source devices relative to playback equipment without the need for adapters.

Advantages

The cable provides straightforward stereo interconnection between consumer devices and audio equipment using standard 3.5 mm and RCA connectors. With a 3‑metre length it reduces the need for extensions and allows convenient routing in home and vehicle installations. The cable is compatible with most devices that use an unbalanced stereo TRS output and accepts standard RCA inputs on amplifiers and speakers.

Suitable for

• Connecting smartphones, tablets or laptops to home amplifiers or powered speakers
• Linking portable music players to stereo systems or car auxiliary inputs
• Temporary or permanent audio feeds in multimedia setups and presentations

When it may not be suitable

This cable carries an unbalanced stereo signal and is not intended for professional balanced audio connections or microphone-level signals. It may not be suitable where balanced XLR or TRS connections, digital audio interfaces, or very long cable runs with strict noise rejection are required.

Key specifications

• Connector A: 3.5 mm TRS (stereo jack, male)
• Connector B: 2 × RCA (Cinch, male)
• Length: 3 metres
• Signal type: Analog stereo (unbalanced)

How to use

Insert the 3.5 mm TRS jack into the headphone or line‑out socket of the source device. Plug the two RCA connectors into the corresponding left (white) and right (red) inputs on the amplifier, speaker or car stereo. Ensure the source device volume is set at a moderate level before playback and adjust the receiving device’s input level to achieve the desired listening volume. When unplugging, grasp the connector body rather than pulling the cable.

What to consider before purchase

• Confirm that your source uses a stereo 3.5 mm TRS output and the target device accepts RCA inputs
• Check that a 3 m cable length suits your installation and routing needs
• Consider whether a balanced cable or a digital connection is required for noise-sensitive or professional setups

Usage recommendations

For best performance, route the cable away from power cords and large transformers to minimise hum and interference. Use firm but gentle insertion and removal of connectors and avoid sharp bends near the ends to prolong cable life.
