This ALLTEQ jack cable is used for connecting audio equipment with different jack connections. The cable transmits analog audio signals between devices such as smartphones, tablets, audio equipment, amplifiers, and speakers with a 2.5 mm or 3.5 mm audio connection. The cable features a 2.5 mm male jack connector on one side and a 3.5 mm male jack connector on the other side. This allows audio equipment with different jack sizes to be connected to each other. The cable supports stereo audio, transmitting two audio signals via one cable, for example, a left and right channel. The flexible cable jacket protects the internal conductors and makes the cable suitable for daily use. The connectors are made of solid material and ensure a stable mechanical connection with the connected equipment. Specifications Brand: ALLTEQ Cable type: Jack audio cable Audio type: Analog audio connection Connector 1: 2.5 mm jack male Connector 2: 3.5 mm jack male Connector type: TRS Mono / stereo: Stereo Conductor material: Copper Color: Black Warranty: 5 years Certifications: CE, RoHS, REACH Explanation 2.5 mm jack: A compact audio connector used in headsets, communication equipment, and certain portable audio devices. This connection is used less frequently than 3.5 mm jack. 3.5 mm jack: A widely used audio connector for headphones, AUX connections, and portable audio devices such as smartphones, tablets, and laptops. TRS connector: A jack connector with three contacts (Tip, Ring, and Sleeve). This allows two audio signals to be transmitted, enabling stereo audio. Applications • Connection between devices with 2.5 mm and 3.5 mm audio connection • Connecting portable audio equipment to amplifiers or speakers • Use as an AUX cable with audio equipment • Connection between multimedia devices and audio systems 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. TRS can also be used for balanced audio signals in professional audio equipment. 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, for example, with headsets. 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 with less noise. Unbalanced audio: A form of audio transmission using one signal wire and one ground wire. This type of connection is commonly used in consumer equipment such as smartphones, laptops, and Hi-Fi systems. Stereo audio: An audio system using two separate channels: a left channel and a right channel. This creates a spatial sound image. Mono audio: An audio system using only one audio channel and sending the same signal to all speakers. Ask a product question
