The Series 4 Portable Electronics Y Adapter cables facilitate connecting your PC's sound card or a portable audio device, like an iPod, with a 1/8" mini stereo plug, to your home stereo system with left/right RCA audio inputs. These 4YP adapter cables commence with ultra-pure, highly conductive oxygen-free copper (HC-OFC) designed for audio applications. Tributaries' Twin-Axial cable design is ideal for unbalanced analog audio systems, featuring dedicated conductors with equal impedance for positive and negative signals. The signal conductors are encased in dual shielding to prevent noise interference. Conductors are solid gauge to avoid distortion from stranded wire. The Series 4 Portable Electronics Y Adapter cable delivers high-performance audio that's as pleasing to the eye as it is to the ear.
