The present invention provides an infrared remote control receiver with increased suppression of unwanted light, signals, or interference, specifically suppression of interference from plasma television displays and fluorescent light. The infrared remote control receiver may be used in remot e control applications whereby it is connected between at least one remote control unit and at least one device or component that is intended to be operated. The receiver also contains status and infrared activity indicators , which indicate whether the individual components of the system are powered a nd whether the receiver is receiving an infrared signal. The receiver eliminate s or reduces interference received by the receiver using a method of processin g signals that changes the voltage reference level if the signal is determined to be noise and maintains the noise level at an established limit.
