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. This allows an existing 3.5 mm audio cable to be easily extended without any noticeable change in audio quality. The connectors are equipped with gold-plated contacts that ensure a stable electrical connection and protection against oxidation. The flexible cable construction makes the cable suitable for daily use with various audio devices. Specifications Brand: ALLTEQ Cable type: jack extension cable Audio type: analog audio connection Connector 1: 3.5 mm male jack Connector 2: 3.5 mm female jack Connector type: TRS (3-pole) Mono / stereo: stereo Contact material: gold-plated 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. Female jack 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. 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 carries 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 a microphone signal to be transmitted via the same connector in addition to stereo audio. Explanation of audio signals Balanced audio: an audio transmission method using two signal wires and a ground. Interference picked up along the way is canceled out at the receiver, creating 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 widely used in consumer electronics. 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 and sends 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 that restricts 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.
