The multi-functional new GefenTV 2.1 Digital Audio Amplifier w/Volume Stabilizer supports the connection of three different audio inputs using digital (TOSlink; S/PDIF) and analog (L/R) audio formats. The selected input is delivered as L/R analog audio to a pair of speakers using standard binding posts with 50 watts per channel amplification. A powered subwoofer can also be connected to a line level RCA output. When a digital audio input is selected, the GefenTV 2.1 Digital Audio Amplifier automatically down mixes it to 2.1 channels. The audio output includes Dolby Volume Technology that automatically evens the volume between different audio sources. Dolby Volume Technology performs a seamless audio leveling that in no way interferes with the natural highs and lows of an audio program such as a movie. It can also be bypassed, if desired.
