Hot Link Pro completes your home theater system with a super slim-line infrared eye!The Hot Link patented system constantly monitors the ambient light and noise floor. In darker ambient light it becomes more sensitive to remote control pulses, making the eye the most sensitive it can be based on ambient light environment. When the eye is in a "hidden" location behind a speaker grill, tucked up in a toe-kick or in a door slot it compensates for the expected loss in distance by becoming more sensitive to the pulses emitted from remote controls. Get great remote control roaming freedom, and enhanced beauty of your home theater.
