To minimize interference when running cables for microphones and power, what is MOST important when creating the bill of materials?

• A. Specify twisted pair cabling.
• B. Terminate their ground connections together.
• C. Specify a conduit with sufficient capacity.
• D. Create as much space between them as possible.

Answer: (A)

Selecting twisted pair cabling is the best choice for minimizing interference when running microphone and power cables. Twisted pair cables are specifically designed to reduce electromagnetic interference (EMI) by having pairs of wires twisted together. This design helps to cancel out noise from external sources and also reduces crosstalk between adjacent cables. Utilizing twisted pair cabling can significantly improve the clarity and quality of audio signals transmitted from the microphones, making it a fundamental consideration in the bill of materials. While other options may address certain aspects of cable installation—such as grounding practices, conduit capacity, or physical spacing—the inherent properties of twisted pair cabling provide a more effective solution to mitigate interference in the first place. This is particularly important in environments where audio quality is critical, ensuring that the microphones function optimally without the detrimental effects of electrical noise.
