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.

6 Audio Outputs (1 through 3) connectors — Connect up to three
balanced or unbalanced audio devices to these 3.5 mm, 5-pole
captive screw connectors. Connect audio devices, such as an
audio amplifier or powered speakers. See figure 10 to properly
wire an output connector.

Composite video (MDA 3V, MDA 3AV, MDA 3V Dual)
3 In connector or Input connector — Connect a composite video
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.
4 Out connector or Outputs (1 through 3) connectors — Connect
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)
5 Audio Input connector — Connect a balanced or unbalanced
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.
