- Shield the DC side wires with metal sheathing / copper foil /braiding: - Use coaxial shielded
cable for all antenna inputs (instead of 300 ohm twin leads) - Use high quality shielded
cables to attach audio and video devices to one another.
- Limit operation of other high power loads when operating audio/video equipment.
Buzzing Sound in audio Systems
Some inexpensive sound stereo systems and “Boom Boxes” may emit a buzzing sound
from their speakers when operated from this unit. This is likely to occur because the
power supply in the electronic device does not adequately filter higher frequency har-
monics generated by Modified Sine Wave produced by this unit. The solution is to use
higher quality sound system that incorporates higher quality of interference suppression
in its power supply.
