INSTALLATION AND SETUP

2.10RGB Signals

INPUT 1 provides 5 BNCs (connectors) for linking to a variety of sources. The typical connec- tion would be to an RGB source such as the VHD Ultra Controller, computers or DTV decoders with an RGB output. This projector supports multiple sync types with RGB signals: sync-on- green, composite sync, and separate H & V syncs.

NOTES: Depending on the source, you may need a custom adapter cable that has BNC connec- tors at the projector end and a different type of connector at the other (such as a 15-pin “D” con- nector for computer sources). Contact your Runco dealer.

Connect the SYNC BNC input(s) first. Then connect the red, green and blue source outputs to the RED, GREEN, and BLUE BNCs on the INPUT 1 panel. If the source uses sync-on-green, only the red, green, and blue connections are required. If the source provides a composite sync output, connect it to the SYNC input labeled HOR/COMP. If the source provides separate horizontal and vertical sync outputs, connect horizontal sync to the SYNC input labeled HOR/COMP and connect vertical sync to SYNC input labeled VERT. See below.

NOTE: To connect YPbPr signals, such as from analog HDTV sources, to INPUT 1, use the red, green and blue BNCs as described in YPbPr Signals later in this section.

Connecting RGB Input

AUDIO for INPUT 1: To control audio levels in an audio/visual system, connect pre-amplified (line level) audio inputs to the “IN 1” left and right channel audio inputs located near the top left corner of the rear input panel. Then connect external audio amplification equipment to audio “OUT” for sound output. Audio connection cables require standard RCA type phono plugs.
