Una opción para cables RCA: Instrument and microphone cable
Instrument and microphone cable must provide a very good shielding to block noise and radio frequencies (RF) and it is designed to deliver a wide frequency band. This makes a lot of sense as instrument cables are used with guitars, microphones and studio equipment. Why should this not work for interconnects? That was the quest(ion).
