LA Home Studio RCA Guide

From Hollywood post-production suites to home studios in Silver Lake, audio quality is Los Angeles‘s obsession. RCA cables are the backbone of analog audio interconnections, but not all are created equal.

The debate between oxygen-free copper (OFC) and copper-clad aluminum (CCA) is relevant here. OFC offers lower resistance—about 40% less than CCA—resulting in better signal transfer, particularly for long cable runs. Shielding is crucial in LA‘s RF-dense environment; double-braided shielding offers maximum protection against hum and interference.

For subwoofers, use a dedicated subwoofer cable (often with heavier gauge and a single RCA plug) rather than a standard stereo interconnect. And don‘t confuse RCA with digital coaxial—while they look similar, digital coaxial cables are designed for 75-ohm impedance and shouldn‘t be used for analog audio. Trust your ears, but start with quality copper.
