Why is it recommended to use RCA cables provided by the customer when possible?

• A. They are always higher quality.
• B. They are tested and calibrated by the operator.
• C. Customer-supplied cables are sometimes of questionable quality.
• D. They come with warranties.

Answer: (C)

Quality of customer-supplied RCA cables can vary, so use them when they meet acceptable standards for the installation. RCA cables affect signal quality through shielding, conductor quality, and impedance matching, so poorer cables can introduce noise or signal loss. Because customer-supplied cables are sometimes of questionable quality, relying on them without verification can lead to degraded performance. If they’re in good condition and the length and connectors fit the setup, using them can save time; otherwise, substituting your own tested, high-quality cables helps ensure reliable service. Warranties or automatic testing aren’t guaranteed for customer-provided cables, and they aren’t inherently higher quality.
