Captive Screw
Connecting
Captive screw balanced audio connector is an added feature on the Atlona HDMI Distribution
Amplifier. The Captive screw connectors allow you to cut cables down to a suitable length,
reducing cable clutter while providing a more reliable connection.
The captive screw connector ports have a contact bar that is adjusted to compress the wire against
the top contact plate. Use the screws at the top of the connector to compress the wire against the
contact plate.
When connecting a cable to the audio captive screw connector it is important that the wires are
correctly terminated. The captive screw connector (see picture A) has a contact plate at the top and
must have the wire touch it for signal to pass. When wired correctly (see picture B) the signal will
pass, incorrectly (see picture C) no signal will pass.

The HDDA is compatible with a combination of DVI and HDMI interfaces. Please use the EDID learn table below for the
best compatibility.
The HDDA supports two different types of audio
terminations: balanced and unbalanced. To be sure which to
use, refer to the manual for the connected device.
Balanced audio left and right connections consist of a
negative, a positive, and a ground.
Note: Jacket colors may vary by cable manufacturer, be sure to use
the same pin out on the left as on the right or audio performance
may be undesirable.
Unbalanced audio consists of a positive and a ground for left
and right connections.
With pre-stripped wires the AT-LC-CS-2CH-2M (purchase
separately at atlona.com) provides an easy to integrate
unbalanced audio connection. Refer to the picture on the right
for an example of a terminated unbalanced connection.
