The Challenge

There are numerous challenges facing integrators when designing audio-visual systems for corporate presentation facilities. Systems integrators must deal with client furnished equipment, such as VHS or DVD players, analog cable boxes, document cameras, and video conference gear. Designers must support newer digital sources, including iPad, iPhone, media players, and digital satellite boxes with incompatible signal types and connectors. And, the customer always seems to ask for expandability for new technology that they are expecting to implement in the future.

Meeting the Challenge

To meet this challenge, Presentation Switchers developed a line of modular digital presentation switchers called the "Series 500".

Each system begins with the selection of a modular enclosure - the PS550 is the most popular North American version. Each enclosure has power, communication, and audio and video output boards. The designer will then select a series of input card assemblies (HDMI, VGA, DVI, DisplayPort, Component, Composite, and S-Video) to meet the requirements of the particular installation. Here is a typical PS550 configuration:

In this example, we are utilizing an existing PC, VHS player, and satellite receiver - all using analog audio and video signal formats. Additionally, the design includes a BluRay player using HDMI, an Apple MacBook with DisplayPort, and a high resolution Document Camera on DVI-D with one more slot available for future expansion.

For outputs, we can either use an existing (client furnished) XGA resolution projector using VGA or utilize a new HDTV 1080p LCD panel using HDMI - the PS550 supports up to 1920 X 1200 resolution. Audio is provided on balanced line level outputs (stereo or mono) and on commerical 70V (North America) or 100V (European) speaker level outputs. 100 watts of amplified power supports up to 10 speakers at 10 watts each or 20 speakers at 5 watts each - plenty of coverage for conference rooms up to 100 people.

Going Beyond the Challenge

The Series 500 offers additional "automation" features that integrators and end users alike will appreciate: Auto-Switching, Display Controls and Control System Feedback.

Auto-switching

In this user selectable mode, if a presenter connects to any port on the Series 500 and activates his/her device (laptop etc), the Series 500 recognizes the new signal and automatically switches to that input and displays the new source on the LCD/Plasma Display or Projector. If the system was in standby mode, the Series 500 can turn on the projector and lower the projection screen.

Display Controls

Integrated into the Series 500 is the ability to control Projectors or LCD/Plasma Displays via RS-232 commands. A pair of contact closures also allow for simple relay control of an electric screen or privacy drapes. An easy-to-use, “Set and Forget” Graphic User Interface (GUI) makes set up a breeze and eliminates the need for large control systems for simple room configurations.

Control System Feedback

When integrated with a 3rd party control system, such as a Crestron or AMX controller, the Series 500 automatically notifies the controller when a switch occurs - either an auto-switch or a manual switch from the front panel. It also notifies when the user manually changes the volume from the front panel. This feature eliminates the control system having to poll the Series 500 for status changes - reducing the amount of code and lowering programming costs. The control system also appears "more responsive" when changes occur by immediately updating the panel to reflect the changes as they happen.

In Conclusion

With the convergence of analog and digital signals today, integrators are finding it increasingly difficult to accommodate existing and new age equipment in classroom and lecture hall designs with traditional, fixed configuration switchers.

Presentation Switchers, with its Series 500 line of modular digital presentation switchers provide near-limitless solutions integrating analog and digital devices in classroom environments - with ease. Presentation Switchers is quickly becoming the worldwide "go-to" source for digital presentation systems.
