In addition, the switcher extracts digital audio from each source, and outputs it as S/PDIF Toslink or two-channel audio. Specifically, it extracts LPCM 2.0 or 5.1, Dolby 5.1 and DTS 5.1 audio and delivers it as digital S/PDIF Toslink. LPCM 2.0 audio can be extracted and delivered as analog two-channel audio using standard RCA jacks. The Switcher also supports HDMI pass-through of all digital audio modes including LPCM 7.1, Dolby TrueHD, Dolby Digital Plus, Dolby Atmos, DTS-HD Master Audio and DTS:X. Users have the option of selecting between four HDMI inputs, and three audio modes of pass-through, 2.0 and 5.1 audio using the switcher’s front panel buttons or the IR remote control.
The switcher’s Audio Return Channel (ARC) sends selected audio back to the source. Additional audio equipment can then be connected to amplify surround sound and higher-level audio in the viewing environment. The rugged enclosure provides all connectors on the rear panel for a tidy installation.
