What is the Audio/Video EQ switch?
When placed in the video position, your amplified subwoofer system will automatically boost output in the very low frequency range. Experiment with this setting to achieve the most desirable effect for you. Fuse Should your amplified subwoofer system fail to operate, remove the fuse and check prior to calling for service. If blown, replace with a fuse of the same amperage rating. If you would like us to send you a fuse, contact Debbie Swinton in our service department.
