4 x 1 HDMI Audio switch with ARC and Optical Audio output


Simplify HDMI video switching and Toslink Optical Audio integration with sound systems and soundbars such as the Sonos® Playbar.

Enables simple integration of ARC enabled Display with non-HDMI AV Amp

The HD41ARC HDMI switch supports 4 HDMI sources and converts the connected HDMI source audio to Optical Audio output. Built in EDID Management is configured with 2Ch PCM, 5.1 audio fields ensuring that the connected sources can output  5.1 audio when available even if your HDTV does not supported it. Thus allowing you to get optimal performance from your sound system via Optical Audio. The HD41ARC switch utilizes the latest switching technology to provide very Fast Switching.

Designed to work with HDTV's with ARC(audio return channel) and your existing audio receiver system with Optical Audio Inputs.

The Octava 4x1 HDMI switch +ARC includes: 4 HDMI inputs, 4 Optical Audio inputs, 1 Optical Audio output, 1 HDMI output with ARC support.

The Optical Audio Output can operate in 3 modes thus allow users total flexibility :

1) convert HDMI Input source to Optical Audio Format

2) convert HDMI ARC from HDTV to Optical Audio Format

3) Switch directly from 4 Optical inputs to the Optical Output

When used in the Optical switching mode, the Optical source can be independent from HDMI source selection. For example, you may view a video on the HDTV while listening to a different audio source via Optical Input.

Clear EYETM transmission line and ISI reduction design will ensure pristine digital video signal from source to display. Smart ScanTM algorithm intelligently selects the correct HDMI source so you can enjoy the program instead of fumbling with the remote.
