Why does anyone need a surge suppressor? Most importantly, users need it to protect its valuable equipment investment against damage. Think of a surge suppressor as an "insurance policy". It is a small cost to pay for peace-of-mind, especially when it is compared to the high cost of replacing or repairing a damaged system. Additionally, when adding up the costs of a system, it is important to include not only the hardware costs, but the often overlooked costs of replacing lost data and recordings as well as making up for lost productivity or enjoyment. In addition to acting as an "insurance policy", surge suppressors also act as "power filters." Users expect the highest level of audio/video and processing performance from the equipment, regardless of the power environment it operates in. Surge suppressors remove disruptive line noise to help equipment perform at their peak.
