Important Note Regarding the HDMI Interface
The High-Definition Multimedia Interface (HDMI) is an all-digital audio and video interface. HDMI provides a digital interface between any audio and video source. HDMI supports standard, enhanced, or high-definition video, plus digital audio.
Some HDTVs do not contain circuitry to decode Dolby® Digital formatted content. If you connect your DVR to an HDTV that cannot support Dolby Digital audio, the HDMI interface instructs the DVR to switch its audio outputs to
2-channel PCM audio (to be compatible with the HDTV). In this case, all digital audio outputs on the DVR are formatted as 2-channel PCM. As a result, you will not be able to receive Dolby Digital or DTS audio on your home theater system when connected to either the optical or coax (RCA Connector) S/PDIF ports. You can avoid this by overriding the automatic configuration through the General Settings menu and switching the audio output to Dolby Digital.
Important: If your HDTV cannot decode Dolby Digital formatted content and you have configured the DVR to output in the Dolby Digital format, you will not be able to listen to audio through the TV. Instead, you must use your home theater or your Dolby Digital decoding device in order to hear audio. Alternatively, you can reconfigure the DVR to output 2-channel PCM any time you want to use the TV to produce the audio portion of the content by selecting HDMI in the General Settings - Audio Output screen. Depending upon your equipment capabilities to select alternate audio sources for input, other configurations may be possible. Refer to your equipment user’s guides for more information.
