Atlona Technologies’ HDMI 1.3 Audio De-Embedder was designed for users to isolate high-quality digital audio signal from multiple HDMI sources.
The AT-HD577, a professional version of the AT-HD570, offers a number of options for re-routing audio including standard stereo (RCA) audio, digital coaxial, and optical.
This Audio De-Embedder enables the availability to remove the audio from an HDMI source so that it be re-routed to a secondary audio output device. The unit also offers 2×1 HDMI switching for applications requiring easy access to multiple HDMI sources such as HDMI home theater systems and PC HDMI/DVI devices.
The AT-HD577 offers high-bit-rate HDMI 1.3 data that can scale down the color depth, allowing compliancy with HDMI 1.2 and DVI 1.1 to ease the limitation of the transmission distance and gain higher compatibility to the display without noticeable video degradation.
The beneficial purpose of replacing the AT-HD577 with RCA instead of the AT-HD570’s 3.5mm ports was specifically for the purpose of more conventional audio ports for easier connection to a home theater, or alternative audio sources.
To broaden the spectrum of HDMI audio output, 7.1-channel analog audio outputs and stereo S/PDIF in both Toslink and RCA connectors are integrated into this new unit.
