Figure 2-2a. The left side of the rear panel has four of the five inputs.

6PC1 input is on the Front Panel and accepts laptop

video through a VGA connector as well as 2-channel audio through a 3.5 mm jack, as shown in Figure 2-2. With a buffered output, VGA signals can be driven up to 50 feet without additional amplification.

Figure 2-3. PC1 Input is on the Front Panel.

Audio Input Connections

Connect balanced or unbalanced, 2-channel audio to the input connectors marked L and R, using a captive screw connector. Possible connections are shown in Figure 2-4b. Connectors are included with each System 5, however, cables are the responsibility of the installer.

Figure 2-4a. Audio Input can be connected three different ways with the captive screw connectors.

Strip about 0.25” of insulation from each wire and insert it into the appropriate connector hole. Do not solder the wires. Turn the screw counterclockwise to allow the opening to accommodate the wire. Turn the screw clockwise to secure the wire in place. Repeat for each wire.

The PC1 audio input uses a 3.5 mm, round stereo connector, as shown in Figure 2-4c. Unscrew the barrel of the connector to expose the inside connections. Slide the barrel over the cable, as shown here. Cut and strip a wire to an appropriate length for each of the ring, tip and sleeve solder points. Insert each wire into its respective hole and solder it in place.

Video Output Connections

The System 5 has BNC output connectors for three video formats (RGBHV, Composite, and S-video). Which output connectors are active depends upon the format of the selected input. The green LED to the right of each connector, or set of connectors, lights to show which output is active. Only one output is active at any one time.
