Hot Link Pro repeats everything from 18Khz to 120Khz. This means that the HDTV receivers and cable boxes that use 58Khz and 60Khz will work just as easily as all of the standard 38Khz and 40Khz AV gear. Hot Link Pro doubles the distance of IR computer mice and keyboards and PDA IR Remote Control Signals.
Hot Link Pro will not repeat only a handful of signals. Pioneer "Elite" receivers which use 1MGHz, some high-end Kenwood receivers and Sony ES receivers with a 2-way remote and Sony CDX series automotive CD players that use 455KHz. It is not designed to transfer IRDA standard IR pulses for PDAs.
