S-video (MDA 3SV and MDA 3SVA)
a Input connectors — Connect an S-video input to this four-pin mini DIN connector.
b Out connector or Outputs (1 through 3) connectors — Connect up to three S-video devices to these four-pin mini DIN
connectors.
Composite Video (MDA 3V, MDA 3AV, and MDA 3V Dual)
c In connector or Input connector — Connect a composite video input to this BNC connector. On the Dual model, Input A and
Input B are completely separate inputs to two separate distribution amplifiers.
d Out connector or Outputs (1 through 3) connectors — Connect up to three composite video devices to these BNC
connectors. On the Dual model, 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)
e Audio Input connector — Connect a balanced or unbalanced audio input to this 3.5 mm, five-pole captive screw connector.
Connectors are included, but you must supply the audio cable. See figure 2 to wire a connector for the appropriate input type
and impedance level. High impedance is generally over 800 ohms.
