Introducing Stage Right by Monoprice STARQUAD XLR Microphone Cables. These are Pro-Grade, balanced microphone cables, commonly used to carry low-level signals. Microphones produce very low level signal feeds, which are easily susceptible to magnetic interference. Microphone outputs must be amplified and when a microphone feed is amplified, any interference will also be amplified. Stage Right STARQUAD XLR Microphone Cables' four cores are very tightly twisted with each other and rotate over a relatively short length, very similar to what is found in an Ethernet cable. This arrangement results in a greatly improved rejection of electromagnetic interference, compared to standard two-core balanced mic cables. Because of the nature of taking a performance on tour, the layout of the venue and the stage is widely unknown. Using Stage Right STARQUAD XLR Microphone Cables will ensure a noise-free performance, no matter where the road takes you. Backed by Monoprice. trust that you and your crew will enjoy many years' worth of noise free performance.
