CEDIA ESPA EST Practice Test

Answer - C - The upper limit of the threshold capacitance above which you should consider replacing the capacitance is 100 pF/ft.

Key Takeaway: Capacitance of an audio cable should be tested with a multimeter. Excessive cable capacitance is a common problem on audio lines that are more than 100 feet or 30 meters in length. A very high capacitance interferes with systems that have high impedance. If the capacitance is too high, you should consider replacing the cable with one that is rated at less than 100 picofarads per foot (pF/ft).
