• Example #2—If there is hum coming out of powered speakers that are 
connected to a mixer: Plug the mixer outputs into the inputs of the Humbuster, 
and the outputs of the Humbuster into the inputs of powered speakers.
• Example #3—If you experience hum and noise when connecting the 
unbalanced output of a computer sound card to a mixer: Plug the outputs 
of the sound card into the inputs of the Humbuster, and the outputs of the 
Humbuster to the inputs of the mixer.
• Also great for live sound and recording studios, long runs of unbalanced 
cables across a stage, DJ mixers, home theaters, and broadcast and video 
studios.
IMPORTANT: Do not use the Humbuster between an amplier and speakers. 
Doing so can damage the equipment. Use the Humbuster only on non-powered, 
line-level signals.
