If there is current sound between amp and speaker, or speaker itself, install this between amp and speaker. If a laptop is connected to projector and power amp, there may be noise. Use power adapter or battery for laptop; disconnecting the power amp or projector can remove noise. Then connect computer headphone jack and power amp with a common ground isolator to remove noise. Unable to noise problems: Noise from non-common ground (electromagnetic interference) cannot be filtered by this model. Confirm noise source before purchase. Isolation effect varies by user perception. This product is an audio common ground isolator, effective for noise from common ground of audio source and receiving equipment.
