Krystal 18 AWG Installation Microphone Cable – Powerful & Reliable Audio Solution The Krystal 18 AWG Installation Microphone Cable (MIC-INS-18-ATC) is built for high-performance fixed audio installations where strong signal transmission and durability are essential. With its thicker 18 AWG annealed tinned copper (ATC) conductors and high-density braid shielding, this cable delivers clear, stable, and interference-free sound even over long distances. Ideal for auditoriums, conference halls, schools, offices, and commercial audio systems, this cable ensures consistent performance and long-lasting reliability in every installation. Frequently Asked Questions (FAQs) 1. Where can this cable be used?A-1 It is ideal for fixed installations such as auditoriums, offices, schools, conference rooms, and PA systems. 2. Why choose 18 AWG cable?A-2 18 AWG is thicker than 20 or 24 AWG, offering better signal strength and improved performance over longer distances. 3. Does it prevent noise and interference?A-3 Yes, the high braid shielding (85% coverage) minimizes electromagnetic interference for clean audio. 4. Is this cable suitable for outdoor use?A-4 It is mainly designed for indoor installations but can be used in protected outdoor environments. 5. Is the cable durable for long-term use?A-5 Yes, with a strong PVC jacket, moisture-resistant layer, and high tensile strength, it is built for long-lasting performance.
