These high-quality aeco ARP-4055 RCA connectors, sold in packs of 4, benefit from a rigorous design using top-of-the-range materials. The contacts are 99.9% pure silver, ensuring perfect conductivity. The insulation is made of glass-fibre reinforced nylon with a star shape for a firm connection, and the outer shell is made of brass for durability. The connectors have a short format with a reduced conductor size, limiting resistance, capacitance and inductance sensitivity during signal transmission. They also accept cables up to Ø10.5mm in diameter, which is held in place by a screw.
