Audio adapter plug-to-socket SpeaKa Professional SP-13808968 — 1× 3.5 mm jack to RCA

SpeaKa Professional SP-13808968 is an audio adapter that converts a single 3.5 mm stereo jack to a pair of RCA connectors. It enables devices with a 3.5 mm audio output—such as smartphones, laptops and portable music players—to be connected to amplifiers, powered speakers, AV receivers or other equipment with RCA inputs. The adapter is intended for short connection runs where a compact, reliable interface between a headphone-style output and RCA line-level inputs is required.

Advantages

The adapter provides a simple, low-effort solution for linking a 3.5 mm stereo source to RCA-equipped audio gear without the need for active electronics. Its compact form factor reduces cable clutter and is convenient for temporary setups, presentations or connecting portable devices. The direct passive conversion preserves the stereo signal path and is compatible with standard line-level outputs on consumer devices.

Suitable for

• Connecting smartphones, tablets or laptops to home stereo amplifiers
• Linking portable music players to powered speakers
• Feeding AV receivers or mixers from a 3.5 mm output
• Temporary audio connections in presentations and meetings

Key specifications

• Connector A: 1× 3.5 mm stereo jack (male)
• Connector B: 2× RCA sockets (female), left and right channels
• Signal type: Analog stereo line-level
• Cable/adapter type: Passive, no active electronics
• Typical usage: Short-distance interconnection between portable devices and RCA inputs

How to use

Insert the 3.5 mm male jack into the headphone or line-out socket of the source device. Connect the left and right RCA plugs from the receiving cable or equipment to the corresponding RCA sockets on the adapter, matching colors where applicable (white/black = left, red = right). Set source and destination volumes to a low level before playback and adjust to the desired listening level using the connected amplifier or speakers. Ensure secure connections to avoid intermittent signal loss.

Usage recommendations

Use the adapter for line-level connections only; it is not designed to convert mic-level signals or provide impedance matching. Avoid forcing connectors and prevent sharp bends near the connector ends to prolong service life. For permanent installations or long cable runs, consider using dedicated shielded RCA cables or a balanced connection where available.
