What does "bypass AC current capacity" refer to?

The term "bypass AC current capacity" specifically refers to the total AC current that an amplifier can pass to other devices in a system. This is crucial in understanding how amplifiers function within a circuit, particularly in audio and signal processing applications.

When an amplifier is designed, its specifications include how much current it can handle without impacting performance. Bypassing means allowing a direct path for AC current to pass through to achieve better signal quality and to ensure that the amplifier can deliver sufficient power to the connected devices. This capacity is vital to maintain signal integrity and prevent distortion during operation, especially in high-demand scenarios such as when driving speakers or other audio components.

Thus, the notion encapsulated in the correct answer highlights the amplifier's ability to facilitate the flow of current, ensuring that other components in the system receive the appropriate power levels for optimal performance.
