Technical Questions about AFS Cables (Audio and Signal Frequency)

Question 1: What does the acronym AFS mean in this context? Resposta: Although it varies in the market, in the context of specialty cables, AFS generally refers to Audio, Frequency and SignalThese cables are designed to carry low currents (signals) with high fidelity, unlike power cables which are made to carry power (Amperes). They prioritize waveform integrity and noise protection.

Question 2: Can I use an AFS cable to connect power equipment (110/220V)? Resposta: No. AFS cables have insulation and cross-section (gauge) designed for low voltage and low current signals. Connecting them directly to the power grid can cause overheating, short circuits, and fire hazards, as the insulation is not prepared for the grid voltage and the conductor cannot withstand the amperage.

Question 3: What is the difference between spiral shielding and braided shielding for AFS cables? Resposta: The armor in spiral (Copper wires wound in one direction) offers very high flexibility, making it ideal for microphone and instrument cables that are constantly moved on stage. Shielding, on the other hand, is... braid (cross mesh) It offers more robust mechanical coverage and better protection at higher frequencies, making it preferable for fixed or industrial installations where the cable will not be moved frequently.
