Audio cable BLOW 8621 — 3.5 mm stereo plug to 2× RCA sockets, 5 m

BLOW 8621 is a 5-metre audio cable with a 3.5 mm stereo plug (male) on one end and two RCA sockets (female) on the other. Designed to connect devices with a 3.5 mm output — such as smartphones, tablets, laptops or portable audio players — to audio systems that accept RCA inputs, this cable enables a wired, analog audio connection for home audio setups and basic signal routing. The length provides flexibility for placement of source devices and audio equipment while maintaining a simple, low-complexity signal path.

Advantages

The cable offers a straightforward analog connection without converters, ensuring compatibility with a wide range of consumer electronics that use 3.5 mm outputs and RCA inputs. With a 5 m length, it allows greater distance between the source device and the receiving audio equipment, reducing the need to reposition components. The two RCA sockets provide clear left and right channel separation for stereo playback.

Suitable for

• Connecting smartphones, tablets or laptops to amplifiers or receivers
• Linking portable audio players to powered speakers or stereo systems
• Temporary or semi-permanent home audio setups and basic signal routing
• Connecting a computer audio output to an external sound system

Key specifications

• Cable length: 5 metres
• Input connector: 3.5 mm stereo plug (male)
• Output connectors: 2 × RCA sockets (female) for left and right channels
• Signal type: analog stereo audio
• Intended use: consumer audio interconnection for home or portable devices

How to use

Insert the 3.5 mm stereo plug into the headphone or audio output jack of the source device. Plug the two RCA connectors into the corresponding left (usually white) and right (usually red) RCA inputs on the amplifier, receiver or speaker system. Ensure each connector is fully seated to maintain a secure connection. Adjust the source device and amplifier volume levels before playback to avoid sudden loud output. When disconnecting, pull the connectors straight out to avoid stressing the cable.

Usage recommendations

For best results, route the cable away from power cords and sources of electromagnetic interference. Use the full 5 m length only when necessary; coiling excess cable loosely can help prevent tangles but avoid tight bends near the connectors. Check connector polarity and seating if you experience channel imbalance or noise.
