The HTS400 features color-coded outlets and cord labels, so you won't accidentally unplug the wrong component like a VCR, for example, and are forced to reset the blinking clock. A generous eight-foot power cord allows easy reach to your electrical outlets. 24k gold contacts provide maximum power transfer and corrosion resistance. Monster's FlatProfile plug lets you push your furniture flush against the wall. Multiple SurgeGuard protects components from harmful surges and spikes. Harmful power surges and voltage spikes can travel up the AC power line and damage connected equipment. Lightning, automatic garage doors, power tools, refrigerators and fluorescent lights all cause power surges and voltage spikes that effect phone lines and coax cables. Monster's Surge-Guard detects harmful power surges and voltage spikes before they reach components. This HTS400 also features special surge protection for coax cables used for DSS and cable TV connections. Other surge protectors can result in as much as 20 to 30 dB of signal loss, which ultimately affects the output performance of coax connections. Monster's ultra-low loss RF circuitry provides virtually no signal loss to maintain peak performance. Best of all, an audible surge alarm and visual surge indicator warn you of harmful surges and let you know you're getting the most advanced protection available.
