Get the most out of your home theater system with this HDMI Audio Converter from Monoprice! The Monoprice HD Audio Converter taps into the incoming HDMI signal to produce Digital Optical, Digital Coaxial, and Analog 3.5mm TRS stereo audio outputs. The original, unaltered HDMI audio/video signal is sent to your display as normal, while the audio outputs can be connected to your home theater audio system for a superior audio experience. The converter supports all HDMI 3D video modes and high-definition, multichannel audio, including Dolby TrueHD and DTS-HD Master Audio. A switch on the back of the converter allows you to switch between two different audio modes. Mode A allows the capabilities of the display to be sent to the source device. In most cases, this limits the audio output to 2-channel PCM. Mode B allows the source device to output any available audio mode. This allows you to select advanced multichannel audio streams for playback on your home theater audio system. Note: Monoprice strongly recommends using 22AWG, 24AWG, or active HDMI cables with Redmere technology to achieve the best results and to ensure minimum signal loss over longer distances.
