RCA to 1/4 TRS AdaptersWhat is the RCA to 1⁄4 TRS Adapter?
RCA connections are meant to carry unbalanced, mono signals. In audio, these are usually paired as left and right. In some cases, one piece of gear will use RCA left and right pairs while others use a single Tip Ring Sleeve (TRS) plug where the tip contact is meant for the left signal and the ring contact for the right. This is when you would use a dual RCA to 1⁄4” TRS adapter like the Hosa GPR-484.
What is an RCA Cable?
RCA cables were designed in the 1930s and are commonly used for audio or video applications and utilize a phono connector type. They are inherently unbalanced, or mono, meaning a stereo transmission requires two cables carrying the left and right signals independently.
