System overview

The Auditorium Audiovisual System supports presenta-

tions, meetings, conferences and other events in and

around the Auditorium.

The system consists of four subsystems:

RGB Presentation Subsystem: accepts RGB inputs

and routes them to RGB destinations, including either

of two video projectors (one in the Auditorium and

one in the Gallery), large wall-mounted displays in the

facility and either of two 3x3 video walls in the Audi-

torium.

Video Presentation Subsystem: accepts video inputs,

and routes them to video destinations, including either

of two video projectors and the Video Production Sys-

tem.

Video Production Subsystem: accepts video inputs

from the Video Presentation Subsystem, and audio in-

puts from the Audio Subsystem.

Audio Subsystem: accepts audio inputs from a vari-

ety of sources, and routes audio to ceiling speakers, to

the Video Production System, and to other destinations.

A touchscreen permits system conguration from within

the Control Room. A wireless touchscreen enables you tocongure the system while moving about in the Audito-

rium and in nearby areas.

Diagrams on the following pages show major compo-

nents and signal ows for each of the subsystems. Note

that these diagrams show the default system congura-

tion. The system is quite versatile, and can be recong-

ured for a wide variety of events and operations.

About the touchscreens Summary of touchscreen operations

The system is equipped with two touchscreens:

A 12" hardwired touchscreen is positioned on the coun-

ter in front of the racks.

A 7" wireless touchscreen can be used anywhere in the

Auditorium and surrounding areas.

You can easily control most system functions from the

touchscreens, which greatly simplies audiovisual op-

erations. You tell the system what to do by touching the

various buttons you see in the touchscreens display.

To turn on a touchscreen, touch its screen anywhere. If

you dont use a touchscreen for a while, it turns off its

screen to reduce power consumption. To restore the dis-

play, simply touch the screen anywhere.

The wireless touchscreen is stored in a charging base.Because it is powered by internal rechargeable batteries,

it should be stored in the charging base when it is not in

use.

Note: The slowly blinking blue light on the wirelesstouchscreen indicates it is communicating with the

audiovisual system. If the light is not slowly blinking,

there is a problem.

Using the touchscreens you can:

Select program sources, including:

l Rack-mounted computer or connected laptop

l Multistandard (world) VCR

l Recording VCRl DVD player

l DVD recorder

l Television tuner

l Video production subsystem

Route program sources to destinations, including:

l Left and/or right 3x3 video wall

l Projectors

l Floor boxes and wall plates on the stage

l Display in the Assembly Area

l Display in the Gallery

l Displays in the Green Rooms

l Video production subsystem Initiate and control videoteleconferences

Manually turn the video projectors and displays on and

off

Adjust and mute audio volume

Additionally, the touchscreens provide full control over

the RGB and video routers, enabling you to congure the

system for almost any event.

Details for these operations are provided in this section.

Touchscreen tips

Routing a camera to a Video Wall

1. In the touchscreen, touch the Projectors button.

2. At the top of the screen, touch Power ON to turn onthe video walls.

3. When the walls are on, touch the Two Vid Windows.

4. In the sources column, touch the Production button.

5. In the Production Switcher screen, route a camera

into the switcher.

6. In the destinations column, touch Send to Left Wall or

Send to Right Wall.

Heres what happens when you touch Send to Left Wall

or Send to Right Wall:

The selected video source is routed to the RGB scaler.

Output from the scaler is routed to the video wall.

Unconverted video is also sent to the wall.

Audio from the source is sent to the 24-channel mixer

(but if the audio is from a computer source, that audio

is muted).

Why are both RGB and video sent to the walls? It takes

the walls a long time to switch between the Two RGB

Windows and Two Vid Windows presets (thus, you

should avoid switching between these presets during an

event). By having both RGB and video routed to the

walls, you can transition more smoothly. So:

Use the Two Vid Windows preset when you are rout-

ing video cameras or the videoconferencing system to

the walls.

Use the Two RGB Windows preset when you need to

switch between RGB and video sources.

General troubleshooting tips

When a given source doesnt reach the expected destina-

tion:

Be certain that every component in the path is turned

on.

Check routing.

Trace the signal path to nd out which components are

working.

Swap in a known good source.

Swap in a known good destination.

Most audio components have meters that indicate au-

dio presence and signal strength.

Most video devices have video presence lights that in-
