Analog Audio De-Embedding

The AT-RON-448 provides the ability to de-embed two-channel balanced or unbalanced analog
audio on the ANALOG port, using the included 5-pin captive screw connector. This step is
optional.

Use wire strippers to remove enough insulation to allow each wire to be securely fastened to
each terminal of the captive screw connector block and connect the wires as shown.

EDID

The AT-RON-448 provides two EDID modes: internal (INT) and LEARN. Internal mode selects
the highest common resolution and audio between the source and all displays.

NOTE: 4K, 3D, and multichannel audio may not be available when using INT
(internal) EDID mode. When using this mode, the AT-RON-448 will build an
EDID, based on the capabilities of each display that is connected.

LEARN mode will copy the EDID information of the display/sink connected to the HDMI OUT 1
port.

To learn and EDID from the connected sink, press and hold the EDID button. While the EDID is
being learned, the LEARN LED will blink. EDID learn is complete when the LEARN LED glows
solid blue.

Mounting Instructions

The AT-RON-448 provides two rack ears, which can be used to mount the unit in a standard rack
unit.

Troubleshooting

Problem Solution

How do I perform a
rmware update on the

AT-RON-448

Does the Rondo

series provide external
automation control?

3D content is not being
displayed.

If updated rmware is available, both rmware and update
instructions can be found under the Firmware tab of each of
the following links. Note that if new rmware is not available,
then the Firmware tab will not be displayed.

http://www.atlona.com/product/AT-RON-448

No.

• If using INT (internal) EDID mode, all connected displays

• To pass 3D content when not all displays support 3D,

Version 1

must be able to display 3D content. If only one of the
connected displays is not 3D-capable, then none of the
displays will show 3D content.

connect a 3D display to Output 1, then use the “learn
EDID” procedure.
