Captive Screw
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.
Connecting
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 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.
Clockwise
Turn the screws clockwise to raise the contact bar to the upper contact plate and hold the wires in place.
Counter
Clockwise
Turn the screws counter clockwise to lower the contact bar to release the wires.

Balanced
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.
