This ALLTEQ jack cable is used to extend an existing audio cable with a 3.5 mm audio connection. The cable transmits analog audio signals between devices such as smartphones, tablets, laptops, amplifiers, car radios, and speakers via an AUX connection. The cable features a 3.5 mm male jack connector and a 3.5 mm female jack connector, allowing an existing 3.5 mm audio cable to be easily extended so that audio equipment can be connected at a greater distance. The cable supports stereo audio, transmitting two audio signals via a single cable, for example, a left and right channel. The cable has a slimline design with a flexible cable jacket, making it easy to use with compact audio devices. The connectors are equipped with gold-plated contacts that ensure a stable electrical connection and protection against oxidation. Specifications Brand: ALLTEQ Cable type: Jack extension cable Audio type: Analog audio connection Connector 1: 3.5 mm jack male Connector 2: 3.5 mm jack female Connector type: TRS (3-pole) Mono / stereo: Stereo Contact material: Gold-plated Extra: Slimline design Warranty: 5 years 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, car radios, and various audio devices. Jack female connector: A female jack connection into which a male 3.5 mm jack plug can be inserted to extend an existing audio cable. TRS connector: A jack connector with three contacts (Tip, Ring, and Sleeve). This allows two audio signals to be transmitted, enabling stereo audio. Slimline cable: An extra-thin cable construction used when space is limited or when a flexible and lightweight cable is desired. Gold-plated contacts: A thin layer of gold on the contact surface of the connector that reduces oxidation and ensures a stable electrical connection. Applications • Extending an existing 3.5 mm audio cable • Connection between smartphone and audio system • Connecting tablet or laptop to speakers or amplifiers • Use with car radios with AUX connection 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. The tip transmits the audio signal, and the sleeve acts as ground. This configuration is used for mono audio signals. TRS (Tip-Ring-Sleeve): A jack configuration with three contact points. This allows two audio signals to be transmitted, for example, a left and right channel for stereo audio. TRRS (Tip-Ring-Ring-Sleeve): A jack configuration with four contact points. This type of connection allows both stereo audio and a microphone signal to be transmitted via the same connector. Explanation of audio signals Balanced audio: A method of audio transmission using two signal wires and a ground. Interference picked up along the way is cancelled out at the receiver, resulting in a more stable audio signal. Unbalanced audio: A form of audio transmission using one signal wire and one ground wire. This type of connection is commonly used in consumer electronics. Stereo audio: An audio system using two separate channels: a left and a right channel. Mono audio: An audio system using only one audio channel, sending the same signal to all speakers. Explanation of certifications CE: Indicates that the product complies with European directives for safety, health, and environmental protection. RoHS: European directive restricting the use of hazardous substances such as lead, mercury, and cadmium. REACH: European regulation for the registration and control of chemical substances in products. WEEE: Directive for the collection and recycling of electrical and electronic equipment.
