INTRODUCTION
Atlona Technologies AT-HD577 HDMI™ Audio De-Embedder offers the highest compatibility to
HDMI™ 1.3 in the market. This unique device supports the separation of high quality audio from the
incoming HDMI™ signal and make HDMI™ audio more friendly to your expensive audio systems.
Plus, the high bit rate HDMI™ 1.3 data can be scaled down the color depth, which is compliant to
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. To broaden the spectrum of
HDMI™ audio output, high quality 7.1 channel analog audio outputs and stereo S/PDIF in both
Toslink and RCA connectors are seamlessly integrated in AT-HD577.
AT-HD577 is designed to enrich your full digital video and audio experiences at the least expense
in a smoothest way. With built-in HDMI switch, it can serve as a 2x1 HDMI™ switch to easily switch
between HDMI™ home theater systems and PC HDMI™/DVI devices.

EDID LEARNING
NOTICE
OUTPUT FORMAT SELECTION
EDID LEARNING
1. Power up the AT-HD577. Connect to HDMI OUT with the display you want the AT-HD577 to
learn its EDID.
2. To learn the display’s EDID for source device connected to HDMI IN A to play normally, pull
DIP switch pin-1 up-and-down to stay at ON () and wait for about 5 seconds to complete the
EDID learning process. You DON’T NEED to pull up the DIP switch again unless you want to
learn another display’s EDID by pulling DIP switch pin-1 up-and-down once more.
3. To learn the display’s EDID for source device connected to HDMI IN B to play normally, pull
DIP switch pin-2 up-and-down to stay at ON () and wait for about 5 seconds to complete the
EDID learning process. You DON’T NEED to pull up the DIP switch again unless you want to
learn another display’s EDID by pulling DIP switch pin-2 up-and-down once more.
When input signal exists, the output format LED turns on. If the input HDMI™ source is HDMI 1.3
format, you can set the output format to HDMI™ 1.2 mode and red LED will be on. If the input
HDMI™ source is HDMI 1.2, the output format is always set to HDMI™ 1.2. The main purpose of
lower the HDMI™ 1.3 resolution (36~48-bit color depth) to HDMI™ 1.2 (24-bit color depth) is to
increase the transmission distance without creating noticeable video quality distortion still at 1080p.
By pressing the push-in button, users can enforce the HDMI output at HDMI™ 1.2 format for longer
transmission to the display. The AT-HD577 cannot upgrade the HDMI™ 1.2 source content to
become HDMI™ 1.3 format.
1. Depends upon the HDMI™ source content, analog stereo audio output can support up to 7.1channel audio.
2. S/PDIF audio output supports main 2 channel audio output only.
3. The main purpose of lower the HDMI™ 1.3 resolution to HDMI™ 1.2 is to increase the
transmission distance without creating noticeable video quality distortion.
