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.

6Audio 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.

3In 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.

5Audio 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.

CAUTION	Connect the sleeve to ground (Gnd). Connecting
	the sleeve to a negative (-) terminal will damage the
	audio output circuits.
