Composite video (MDA 3V, MDA 3AV, MDA 3V Dual)

In connector or Input connector — Connect a composite video
3
input to this BNC connector. On the Dual model (figure 7),
Input A and Input B are completely separate inputs to two
separate distribution amplifiers.
Out connector or Outputs (1 through 3) connectors — Connect
4
up to three composite video devices to these BNC connectors.
On the Dual model (figure 7), the A output signals are identical
to the A input, and the B output signals are identical to the B
input.
Audio on captive screw connectors (MDA 3AV,
MDA 3SVA, MDA 3A)
Audio Input connector — Connect a balanced or unbalanced
5
audio input to this 3.5 mm, 5-pole captive screw connector.
Connectors are included, but you must supply the audio cable.
See figure 8 to wire a connector for the appropriate input type
and impedance level. High impedance is generally over 800 ohms.

When making connections for the MDA from existing
audio cables, see figure 9. A mono audio connector
consists of the tip and sleeve. A stereo audio connector
consists of the tip, ring and sleeve. The ring, tip, and
sleeve wires are also shown on the captive screw audio
connector diagrams, figure 8 and figure 10.
