Captive Screw
The captive screw connectors allow you to cut cables to a suitable length, reducing cable clutter
while providing a more reliable connection.
Connecting
The captive screw connectors 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 the cables to the female captive screw connector it is important that the wires be
terminated correctly. The female captive screw connector has a contact plate at the top and must
have the wires touching it for signal to pass. When wired correctly
(see picture A)
the signal will pass,
incorrectly
(see picture B)
no signal will pass.

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

Analog Audio
A captive screw analog audio connector is provided to ensure a more reliable and secure
connection. The captive screw connector supports unbalanced and balanced audio output.
Unbalanced audio connections use one signal wire and a ground, when connecting the wires a
jumper between the negative and ground will help alleviate extra noise on the line. Unbalanced
audio connections are used if other system components don’t support balanced signals.
Note:
Pin outs may vary, please refer to the audio device’s manual to ensure a correct connection.
Important!
When terminating cables, please ensure exposed adjacent wires do not touch. This may result in
a short that can damage connected devices.
