This PROCAB jack cable is used to connect devices with a 3.5 mm audio jack to equipment that uses cinch (RCA) connectors. The cable transports analog audio signals between devices such as smartphones, tablets, MP3 players, amplifiers, and loudspeakers. The cable features two RCA male connectors and one 3.5 mm jack female connector. This allows a device with a 3.5 mm jack plug to be connected to audio equipment with RCA inputs. The cable supports stereo audio, transmitting two audio signals via a single connection, for example, a left and right channel. The internal conductors are made of OFC copper and are protected by a flexible cable jacket. Specifications Brand: PROCAB Cable type: jack to cinch adapter cable Audio type: analog audio connection Connector 1: 2 × RCA male Connector 2: 3.5 mm jack female Connector type: TRS to 2 × RCA Mono / stereo: stereo Conductor material: OFC copper Cable type: round cable Certifications: CE, RoHS, REACH, WEEE Explanation 3.5 mm jack: a commonly used audio connector for headphones, AUX connections, and portable audio equipment. This connection is used on smartphones, tablets, laptops, and various audio devices. Cinch (RCA) connector: an analog connector widely used for audio connections on amplifiers, receivers, and speaker systems. TRS connector: a jack connector with three contacts (Tip, Ring, and Sleeve) that allows two audio signals (left and right) to be transmitted via a single connection. OFC copper: oxygen-free copper with a high purity level that ensures low electrical resistance and stable signal transmission. Applications • Connecting a smartphone or MP3 player to an amplifier • Connection between portable audio equipment and loudspeakers • Use with audio equipment with RCA inputs • Transmission of analog stereo audio signals Types of jack connectors 6.3 mm jack: a larger jack connector primarily used with professional audio equipment, musical instruments, and studio installations. 3.5 mm jack: a smaller jack connector widely used in consumer electronics such as smartphones, laptops, tablets, and portable audio devices. 2.5 mm jack: a compact jack connector used in headsets, walkie-talkies, and specialized audio equipment. Explanation of jack configurations TS (Tip-Sleeve): a jack configuration with two contact points for mono audio signals. TRS (Tip-Ring-Sleeve): a jack configuration with three contact points for stereo audio signals. TRRS (Tip-Ring-Ring-Sleeve): a jack configuration with four contact points that can transmit a microphone signal in addition to stereo audio. Explanation of audio signals Stereo audio: an audio system that uses two separate channels: a left and a right channel. Mono audio: an audio system that uses only one audio channel.
