Boosting signal strength in audio systems is primarily achieved through a distribution amplifier. This component is designed to take a single audio signal and amplify it before distributing that signal to multiple outputs, ensuring that the audio maintains clarity and strength over longer distances or when being fed to multiple devices. It effectively prevents signal loss that can occur in long cable runs or when splitting signals, thus maintaining sound quality.

The other components listed serve important roles but are not directly focused on boosting the strength of the audio signal itself. A microphone, for instance, is responsible for capturing sound and converting it into an electrical signal but does not amplify that signal. An equalizer modifies the audio frequencies for better tonal balance and clarity but does not increase the signal strength. A speaker converts electrical signals back into sound waves, but again, it does not boost the strength of the signal being sent to it. Hence, the distribution amplifier is essential for ensuring that audio signals are strong enough for effective transmission throughout an audio system.
