Audio extension cable SpeaKa professional SP-7870384 — 2x RCA plug to 2x RCA socket, 2.50 m

The SpeaKa professional SP-7870384 audio extension cable provides a 2.50 m analog extension for stereo RCA connections. Featuring two RCA male plugs on one end and two RCA female sockets on the other, this cable maintains left and right channel continuity while allowing audio components to be positioned farther apart. The cable is intended for basic line-level audio signals and is compatible with common consumer and professional equipment that use RCA phono connectors.

Advantages

This extension cable preserves stereo signal paths without requiring signal conversion or additional adapters. Its 2.50 m length offers added flexibility for arranging audio components in home stereo systems, AV racks, or small studio setups. The straightforward two-plug to two-socket configuration makes it easy to extend connections between CD/DVD players, receivers, amplifiers, mixers and powered speakers. The cable supports standard unbalanced analog connections and is suitable for everyday audio routing where signal integrity over short distances is required.

Suitable for

• Extending stereo RCA connections between players and amplifiers
• Relocating audio equipment within a home entertainment system
• Temporary patching in rehearsal rooms or small recording setups
• Connecting line-level outputs to inputs in AV setups

Key specifications

• Connector configuration: 2x RCA male to 2x RCA female
• Cable length: 2.50 m
• Signal type: unbalanced analog stereo (left and right channels)
• Compatibility: standard RCA/phono-equipped audio devices
• Application: line-level audio extension for consumer and light professional use

How to use

Plug the two RCA male connectors into the source device’s line-level output (color-coded left/right). Connect the two RCA female sockets to the input cables or device that requires extension. Ensure left and right channels remain matched by color or labeling. Avoid routing the cable near large power transformers or mains cables to reduce potential interference. For best results, confirm secure seating of connectors and test audio levels after connection.

Usage recommendations

Use this cable for short to moderate analog extensions; keep total unbalanced cable runs as short as practical to minimise noise. If longer distances or balanced connections are required, consider using balanced XLR or TRS cabling or a line-level audio transformer instead.
