A New Way to Think About Touchpanel Control Systems Up to now, deploying touchpanel A/V control systems, has remained in a different category from more common pushbutton control panels. While touchpanel systems are generally more elegant, they have been considered more complex, more costly, and more difficult to support than their pushbutton counterparts, due mostly to the programming skills needed for integration. Thanks to Extron TouchLink, the first fully configuration-based touchpanel control system, the industry now has an opportunity to view them in a whole new light. Additional Resources Extron.com offers extensive additional information and training on TouchLink Systems, including: • Spec sheets • Brochures • White papers • Training videos Also, our unique online TouchLink Simulator lets you test drive each touchpanel model, trying it out in various types of presentation environments.

Extron IP Link® control processors, MediaLink® controllers, and now, TouchLink™ Touchpanels have all been designed from a configuration-based approach. For most applications, configurable systems offer significant advantages over programmable systems, and provide benefits for consultants, integrators, end users, and even programmers. The Extron configuration approach simplifies the development of powerful control systems that are cost-effective over the life of the installation. Our library of thousands of Extron Certified device drivers, predesigned application templates, comprehensive suite of software applications, and ongoing training and support, enable system designers to easily and quickly deploy powerful control systems that are reliable, sustainable, and profitable. For most applications, configurable control systems offer significant advantages over programmed control systems, and provide benefits for consultants, integrators, end users, and even programmers. The History of Configurable Control Systems Extron has been delivering fully configurable control systems for more than a decade. System switchers and A/V system controllers such as the MediaLink MLC 206, led the market in being easy to configure and flexible enough to meet many of the typical applications for which they were designed. products alongside the System 5 IP and MediaLink MLC 226 IP defined the next generation of Extron configurable control systems. These products were designed for specific applications and needs of the educational and corporate markets. Alongside these products, Extron developed Global Configurator software to make the configuration process easy, straightforward, and repeatable. The introduction of the IP Link platform of Ethernet based control products enabled the configurable control system to move to the next level of sophistication. The development of the IPL series of While the implementation of a touchpanel control system has been historically considered difficult, time consuming, and costly, the new Extron TouchLink™ system simplifies the process and offers 6 ExtroNews 20.2 | Summer 2009 both extensive flexibility and powerful control features. The fully configurable TouchLink control system also makes for a very cost-effective alternative to a similar programmed touchpanel solution. Fewer Steps in the Process The configurable control system concept started with a few main objectives and expanded to encompass the many growing requirements of typical audio visual installations. One objective of the configurable solutions available from Extron is to make the most common system configuration tasks easy to accomplish in as few steps as possible. One way conFIgurABle control sYsteMs Global Configurator 3.0 is the unified configuration platform for Extron configurable control systems, which include IP Link®, MediaLink®, and TouchLink™ we’ve achieved this objective is through a standardized approach to the development of device drivers. Extron Certified Device Drivers At the core of our configurable solution is a large and comprehensive database of pre-developed, tested, and documented device drivers. Standardization of the device driver creation is critical to the implementation of configuration software features such as creating cookie cutter systems, making drivers easy to replace, and deploying a configuration generated, Web-based resource management system. No Programming Skills Required Another objective of configurable control systems is to make implementation and support of these systems attainable by most entry level technical people. In a few hours of hands-on training, A/V support personnel can be instructed on how to maintain and update their systems, as in the case of a video projector that needs to be replaced due to obsolescence. Configurable systems allow focus to be applied to the environment’s requirements and not the design of the program that will operate the system. The key to making configuration tasks easy to accomplish by even entry level personnel has been the development of Extron Global Configurator software as a unified tool for configuring a wide range of Extron control systems. Global Configurator offers a drag-and-drop interface, reduced training requirements, and zero control system debugging. It was developed as a single unified software platform for all configurable controllers in the Extron product line. Once you are familiar with configuring one controller type, all but the most complex and demanding A/V control applications are easy to accomplish in just a few steps. Enabling more people to create and maintain the A/V control system functionality lowers the cost of the initial installation, as well as ongoing support costs for the life of the products. continued on page 8 www.extron.com 7 conFIgurABle control sYsteMs Configurable Control Systems Who Benefits From a Configurable Solution? The short answer: Everyone. Whether you are an end user, consultant, system integrator, or even an A/V programmer, you can take advantage of the many benefits of a configuration-based control system. Configurable control systems save time: Consultants and system integrators alike benefit when control solutions can be developed in quickly. Faster implementation and integration allows for more cost effective and profitable system designs. Sometimes this is the difference between the customer deciding to implement the system or cut it from their budget. Furthermore, since a configured system can be reliably installed in a shorter time, systems can be installed that offer cost savings for the end user, and higher profits for the system integrator. Configurable control systems cost less to own and operate: The cost of ownership of a system is dictated by the initial cost plus the maintenance cost as the system ages. With configuration software, tasks such as controller setup, system monitoring, scheduling, and Web deployment always require only a few point and click operations. Knowing this makes initial deployment costs easy to estimate and control. System devices, such as projectors, displays, and DVD players, have finite life spans, after which they need to be replaced. The time required to make control system changes is minimized through configuration and this translates into lower costs incurred by the end user. Consistent operation from room to room: End users will find that their Extron A/V control systems operate consistently from room to room, and building to building. This reduces the time required to educate users on the operation of systems that have been implemented by different system integrators. 8 ExtroNews 20.2 | Summer 2009 — continued So how do A/V system programmers benefit from the adoption of configured systems? It frees them up to focus on more complex jobs and provides an opportunity for them to contribute their system expertise to the development of large numbers of configured systems. Programmers typically have a clear understanding of how all the equipment in the system works together. This in-depth knowledge is what makes them invaluable for many complex, one-of-a-kind, “do everything” types of control systems. For many applications, programmers can combine their in-depth system knowledge with configuration tools to help system integrators develop and deliver multiple identical room control systems. These configured systems can be then reliably replicated to support installations ranging from 10 to 1,000+ rooms. Asking a programmer not to program might seem like blasphemy, but in many situations, the combination of a talented programmer and a fully configurable system can produce astounding results. What About Source Code? With configurable control systems from Extron, there is no source code. Configuration files that are stored in the controller prevent the hidden nightmare of “where’s my source code?” that can occur when a system change needs to be made 6, 12, 18 months or more after the initial installation. Global Configurator enables the extraction of the system configuration from all systems. There are no delays in getting modifications done and no learning curve for someone who has used the software previously. Easy-to-Use Configuration Tools The Extron configurable system uses many common software conventions making it much easier for others to learn and master. This means system integrators have access to a larger pool of resources from which to draw upon. Building configuration capability in-house ensures that you have full control over your customer’s needs and sense of urgency. Extron has implemented a standardized approach to the creation of the thousands of existing device drivers. In addition to including the control of the device, each driver includes a communication sheet that completely describes the supported capabilities, including how the control port hardware should be wired to the device. In addition, once a system is configured it can be replicated for similar rooms. Managing a facility that has many configured rooms is facilitated by Free GlobalViewer, a Web-based A/V resource management application, which is automatically generated based on the system requirements and loaded to the controllers. No additional steps or networkoriented setup are necessary. Programmed solutions can be extremely varied and as such, are much more difficult to maintain. Configured systems conversely are systematically consistent, affording more repeatability and maintainability, and reducing service calls and maintenance costs. The Final Analysis With a configurable system design approach, everyone wins: • Systems are designed and deployed consistently. • Variable development and troubleshooting costs are significantly reduced or eliminated • Post-installation support can be easily accomplished by field technicians. There are many aspects of the configuration approach that make it appealing and cost effective. The introduction of the TouchLink series of touchpanels, with ready-to-use templates for common system applications, is the world’s first truly configurable system that can provide a high quality user interface and control project costs at the same time. conFIgurABle control sYsteMs Powerful Control Without Programming For more information, visit www.extron.com/touchlink Global Configurator Anyone familiar with configuring MediaLink® or IP Link® systems using our free Global Configurator software will be comfortable configuring a TouchLink System.

Our new, high-tech training classroom in our Singapore office www.extron.com 11 unIQue technIQues How a Tennessee Utility District Uses WindoWall™ to Improve Operations T wo years ago HB&TS, the Hillsboro, Burwood & Thompson’s Station Utility District, began the planning process for a new command and control center. The utility district is charged with keeping drinking water safe for 6,300 customers in Williamson County, TN. “The district wanted a dramatic look for its command and control center, and that, in itself, meant they needed a display larger than could be done typically with LCDs or plasma screens,” says Tom Semmes, Design Engineer with Multi-Media Solutions, designer and integrator for the project. “Therefore, it was decided early on that the only way they could achieve this impact was with projection, and the Extron WindoWall™ was the natural solution.” Design Goals: Multiple Sources, One Large Screen The WindoWall is a scalable multigraphic videowall processor system that employs proven Extron video processing technologies to deliver a fully optimized, high quality video output. It is ideal for the utility district for a number of reasons. First, it gives them the widescreen capability they need. “We wanted to use the two projectors at their native resolution and we wanted the input, which was a map, to be the background image. And we wanted it to be as large as possible and at the highest resolution,” Semmes says. The command and control center uses two WindoWall processors, two edgematched projectors, and a 60"x160" screen to enable the display of two 1400x1050 images side by side. The display background shows a map of the county's equipment and water supply, often the most important image, across the entire screen. In addition to the background image, each WindoWall processor allows for the display of up to four windows per projector, each of which can show video, HDTV, or high resolution computer-video content. To ensure that vital information is available at all times, the utility district had very specific goals in mind for its A/V system. First, the system had to fully support the district’s SCADA, or Supervisory Control 12 ExtroNews 20.2 | Summer 2009 Operators at the command and control center need to see critical information at a glance, including a topographic map and disaster- and weather-related news local TV stations. and Data Acquisition system, which continually monitors and reports the condition of all utility district devices in the field. In addition, they wanted a videowall system that could handle a wide range of video formats and enable operators to see, at a glance, other critical information, including a topographic map and disaster and weather-related news from local TV stations. With this information, the utility district could then address any issues identified, including equipment problems and potentially dangerous conditions. Finally, the district wanted a presentation system that could support in-service training materials from DVD and other sources. Because they would be using so many different sources and signal types, the district decided to use the Extron CrossPoint 450 Plus 128 HVA UltraWideband Matrix Switcher [now the CrossPoint Ultra 128] for all signal routing, including audio, from the district’s satellite television receivers and DVDVCR. The CrossPoint 450 Plus provides the performance required to maintain signal integrity with the demanding, high resolution signals used in the command and control center. WindoWall Fits the Bill “In a command and control center, when you put something new up on a screen, you don’t want to lose sight of what’s already there,” Semmes says. “You might have windows that display disaster or weather-related items, another window with the SCADA data, and another with a unIQue map that shows the entire area covered by the district. And that’s where the Extron WindoWall has been so useful. Each processor has four open windows in addition to the full-screen background.” With so many different sources and signal types to manage, WindoWall's AutoImage function has streamlined system operation and reduced set-up time for the command and control center. With Auto-Image, each WindowWall processor automatically optimizes the settings for each input signal, saving time and effort when crisp, high resolution images are needed. System Setup and Configuration The entire WindoWall installation, setup, and configuration process was userfriendly, according to Semmes. During the configuration phase, the intuitive Wizards in the WindoWall Console software guided the integrator with a step-bystep process, simplifying system layout configurations. The Wizards provided easy to understand instructions on setting up the system, and enabled the integrator to complete the entire configuration in less than five minutes without any help. In addition, the short SIS™ - Simple technIQues Instruction Set command protocol allowed for easy third-party control and programming. Various window presets were created for recall by a third-party control system, and the different layouts make it possible for operators at the command and control center to view sources collectively and at the same time. This improves efficiency and optimizes time, enabling quicker responses by the operators. WindoWall Console Software Virtual Canvas Practical Room Layout WindoWall Console Software The command and control center has a console with space for three operators. The console faces the large screen, and there are six additional 22" monitors on the console itself, so that the operators can view important information on the big screen or on the monitors in the console. The WindoWall is fully flexible, enabling the operators to size and position each image independently in any way they want. WindoWall Console Software is the user-friendly application designed for fast, easy setup of the WindoWall System. The software simplifies setup with a series of intuitive Wizards that take the user step-by-step through the process of configuring a videowall. A virtual canvas for on-screen visualization enables the user to size and position windows just as they would be shown on the videowall. Operation of the WindowWall System is further simplified with 100 customizable presets that enable users to quickly save and recall window configurations. “We view this project as a total design,” Semmes says. “Anyone could have put in a few panels and equipment, but it wouldn’t have the look, the feel, or the capability that this room has. It really does look like a command and control center.” Features: • Wizard-based graphical user interface for videowall system setup and configuration of all input sources and the matrix switcher to be used in the system • Brings WindoWall Processors and matrix switcher together via TCP/IP • Virtual canvas for on-screen videowall visualization and dynamic window placement and sizing • 100 memory presets for videowall layout configurations The WindoWall is fully flexible, enabling the operators to size and position each image independently in any way they want. continued on page 14 www.extron.com 13 unIQue technIQues H o w a Te n n e s s e e U t i l i t y D i s t r i c t U s e s W i n d o W a l l t o I m p r o v e O p e r a t i o n s — continued a pre-installation design review and system optimization and customer training following the installation, but prior to the system going into full operation. “The Product Commissioning Service was essential,” Semmes says. “Extron has been very helpful.” Each window of the WindoWall can show video, hDTV, or high resolution computer-video content. Plenty of Room for Growth George Gates, CTS, Sales Engineer for Multi-Media Solutions, says the A/V system was designed for future growth. The area served by the utility district is growing rapidly, which means that the utility district customer base is growing. As the district expands, the fully scalable WindoWall System can be expanded as well. Because the WindoWall uses a distributed video processing architecture, dedicating one discrete, real-time processor to each display, the district can easily expand the WindoWall System to support additional display requirements. The WindoWall enables a wide variety of display layouts from 1x2 to 3x4 and larger. frame rate video in each window is ideal for this type of surveillance application. Product Commissioning Service The Product Commissioning process for the utility district took about a day and a half, and included full integration of third-party programming, testing, and optimization of the display’s alignment and color balance. “It was an enjoyable experience that yielded a satisfied integrator and end-user,” says Steve Kolta, Systems Design Engineer at Extron. Watkins adds that the utility district is very happy with the WindoWall System, and they are only beginning to explore the full range of capabilities available to them. Semmes feels that the Extron WindoWall Product Commissioning Service was a major benefit. This setup and calibration service ensures optimum performance in A/V presentation systems utilizing the WindoWall System. The service includes Troy Watkins, System Operator for the utility district, says that because of its mapping system, the command and control center could eventually be used as a war room where strategic decisions are made in the event of a major emergency. In addition, cameras will be installed on all water towers and sites so operators at the command and control center will be able to view the actual tanks and water pumps and be alerted when unauthorized individuals have entered the area. The WindoWall's ability to display real-time, full WindoWall Console software includes a series of step-by-step Wizards that walk the installer through the process necessary to expedite videowall system setup. 14 ExtroNews 20.2 | Summer 2009 unIQue technIQues MGP 464 a Winner at the Pinewood Derby T he 2009 Cub Scouts of America Pinewood Derby marked the 50th anniversary of this annual event held throughout the nation. The derby offers Cub Scouts the opportunity to design, cut, paint, and assemble pinewood vehicles that are pitted against others in a racing competition on a miniature racetrack. This year, Pack 727 of the Melinda Heights Elementary School in Rancho Santa Margarita, California, sought to raise the bar by offering racing participants and viewers a high-tech audiovisual experience that addressed some of the problems typically encountered in past races. As a Cub Scout volunteer and active participant in helping stage the event, Paul Chrisope from Video Resources, knew exactly what the race needed: a large screen display showcasing the race action from multiple viewing angles and real time racing statistics powered by Extron’s MGP 464, a four window multi-graphic processor. switcher. Early on, it became clear that multiple cameras would be needed to help the audience feel close to the action without crowding around the racetrack. The MGP 464's configurable inputs allow the outputs of those cameras to be combined on a single, large display. In this particular case, three of these inputs were routed from two S-video cameras and one composite video camera. Each camera was strategically positioned near the start line, the length of the track, and the finish line. The MGP 464 allows onlookers to watch the race from a distance through multiple camera angles Watching the Race Without Disruptions Choosing the MGP 464 One of the main challenges at the Pinewood Derby is keeping attendees from disrupting the racing event. A room packed with excited Cub Scouts craving derby action can quickly get out of hand. Furthermore, crowds showing up to cheer for racers only adds to the excitement. As a result, a number of distractions posed problems during the racing event. “Hordes of people would gather around the racetrack, kick it inadvertently, and at times, even spill food or drinks on the track,” Chrisope says. “We wanted the audience to have the ability to view the race without disrupting the flow of the event.” As an A/V professional, Chrisope is familiar with the Extron product line, so the first issue was a matter of finding the right product to address the issues. In the end, he decided to use Extron’s MGP 464. Its capabilities would allow the audience to view the race at a distance through multiple camera angles, and create a racing experience that made the audience and participants feel like they were at a NASCAR event. More Than Enough Inputs The MGP 464 is a robust, high resolution graphics processor with the ability to combine four windows on a single display through a built-in 19x4 input matrix In addition, a laptop was used for a fourth input to manually enter and display racing times registered from an optical sensor system placed on the racetrack. This provided real time statistics on every heat of the race, which allowed attendees to keep track of the racers they were following. Furthermore, 15 virtual video inputs on the MGP 464 can accept composite video, S-video, and component video sources. One of these inputs was used for an S-video DVD player that would occasionally play clips of the movie, “Down and Derby”, between races and during intermissions. Chrisope wanted to use a moving digital image as a presentation background, which was not an issue since the MGP 464 contains a dedicated DVI input that displays live, full-motion high resolution computer or HDTV video. To create the feeling of a professional racing environment, a waving continued on page 16 www.extron.com 15 unIQue technIQues MGP 464 a Winner at the Pinewood Derby — continued checkered flag was displayed on the screen during the race. The MGP 464 also has Graphic Still Store capabilities, which allow a presenter to use screen captures of an output or uploaded BMP image files as a background to enhance a presentation. The application required a screen that was large enough for all viewers to see the race. Chrisope used a 12.5-foot diagonal rear projection screen driven by a projector connected to the MGP 464’s RGB output. Typically, from start to finish, a heat will last roughly three seconds, so the MGP 464’s ability to display four images at once gave the audience multiple views of the race, which they wouldn’t see if they were simply standing near the track. window helps the input source deliver the best image quality without affecting the processing for other windows or the overall performance of the MGP 464. Ease of Use Customization Capabilities Although Chrisope is an A/V professional, this was his first time using the MGP 464 and operating the device did not require any specialized training. “One of the reasons I chose the MGP 464 is because of its user-friendliness,” Chrisope notes. “Anybody can operate the MGP 464 with little training.” Chrisope also took advantage of the MGP 464’s full window customization capabilities. The processor can create picture-in-picture window layouts with the ability to size each window and position it anywhere on the display. The image displayed within each window can be sized, panned, cropped, and adjusted for contrast, brightness, color, tint, and other image characteristics. Furthermore, he could add a color border and even a caption to the window and prioritize its order if multiple windows need to be overlapped. Also, when moving between windows, he could apply different transition effects such as dissolve and wipe, or Chrisope configured the MGP 464 prior to the event, but even that task was not too complicated. The AutoImage™ feature on the MGP 464 allows automatic image optimization for the incoming video signals when scaling them to the projector’s resolution. Dedicated video scaling for each Configuring and operating the MGP 464 did not require any special training The MGP 464 gave the derby a look and feel that was similar to a professional racing event 16 ExtroNews 20.2 | Summer 2009 incorporate simple cuts for a smooth and fluid presentation. Window layouts could be saved as presets and recalled at a later time. When Chrisope wasn’t using the four window layout, he could revert to a single window layout to display the racing results. At the event, the MGP 464 was placed on a folding table that served as a makeshift workstation for Chrisope. He was also able to view the action locally while operating the MGP 464 on a computer monitor connected to the MGP’s DVI output. A front panel security lockout kept curious Cub Scouts from changing any settings on the MPG 464. MGP 464 Sets the Standard Chrisope received many compliments related to the A/V setup. “Kids, parents, other Cubmasters, and executives at the district level praised the A/V experience that the MGP 464 helped bring,” he says. “It felt like an actual professional racing event, and the race went on smoothly without any crowd interference.” Looking ahead to the 2010 Pinewood Derby, Chrisope plans to use the MGP 464 again. With the introduction of the new MGP 464 HD-SDI, the ability to use HD-SDI for camera and projector connections is an enticing thought. the clAssrooM connectIon VoiceLift® Microphone Systems Install Voice Amplification Now, Upgrade to a Complete Polevault® A/V System Later I nvestments in classroom A/V technology can be shown to produce significant returns in both long-term cost savings and academic achievement. Unfortunately, a school’s technology wish list can exceed available funding, particularly during a recession. So, is there a cost-effective way to immediately make the learning environment a richer, more meaningful experience for a child, while also providing a platform to build on for the future? Yes. The answer lies in the Extron VoiceLift Microphone System, which enables you to start with voice amplification now and add future upgrades later for completely integrated A/V switching, control and voice amplification for the classroom. commonly referred to as the MARRS Project, have identified the benefits of sound field systems. The rationale underlying sound field systems is very simple: How well children hear a teacher affects how well they learn. The more they can hear, and the less they have to strain and guess, the better chance they will have of learning. The award-winning VoiceLift Microphone System enables the creation of a "sound field" that allows a teacher's voice to be heard clearly throughout the classroom. When You Have to Make a Choice In the capable hands of a dynamic teacher, there are several A/V technologies that have been proven to engage students in the learning experience. These technologies fall into two major categories: • Video, such as a projector, DVD player, computer, and document camera that are available and easy to use, and • Voice amplification that enables every student to hear the teacher’s voice. Implementation of these technology categories in the classroom can now be accomplished in a two-step process, thanks to the award-winning Extron VoiceLift Microphone System. This system creates what is known as a "sound field" that allows a teacher's voice to be heard clearly and more effectively throughout the classroom. What is a Sound Field? A sound field is the area within a classroom where the teacher’s voice is distributed at a consistent level. This sound field is created by a classroom sound system specifically designed to slightly amplify the teacher’s voice using a microphone, audio amplifier, and speakers placed strategically throughout the room. The key to success is not simply amplification or voice level, but increased intelligibility with equal voice level for each student. The purpose of the soundfield system is to ensure that the teacher’s voice is clearly audible above the background sounds at all instructional locations within the room. Students in the back row, and throughout the class, need to hear as well as those in the front row. To achieve this goal, effective sound field systems must accomplish the following: • Raise the level of the teacher’s voice to 15dB above classroom background noise • Distribute sound evenly to each student throughout the entire classroom by using multiple speakers • Provide superior audio performance in frequencies associated with the human voice and full-range reproduction of program audio • Minimize distorted sound Several studies, such as the Mainstream Amplification Resource Room Study, continued on page 18 www.extron.com 17 the clAssrooM Vo i c e L i f t ® M i c r o p h o n e S y s t e m s connectIon — continued Integrated Classroom A/V Systems Extron VoiceLift® System Extron PoleVault® System Shared Components VoiceLift receiver PVS 305 Sa Switcher/ amplifier VoiceLift Pendant Microphone Computer Input Wallplate FF 120 Flat Field™ Speakers VCr/DVD Input Wallplate MediaLink Controller VoiceLift Desktop Charging Station Projector Mounting hardware *Display Projector *A/V Sources Laptop DVD/VCr Combo Player *Projector, DVD/VCr, and Laptop are not included and must be ordered separately. Benefits for Students and Teachers Studies show that significant gains in student achievement and teacher effectiveness can be made by simply ensuring that the teacher can be heard. According to research, even students with normal hearing ability benefit from the use of a voice amplification system. Creating a learning environment where the teacher can be heard is especially critical for children in the lower grades. These 18 ExtroNews 20.2 | Summer 2009 students are often engaged in activities that specifically focus on speech and sound recognition. Young, inexperienced learners do not develop the ability to adjust their hearing in noisy conditions until they are 13-15 years old. For children, the teacher’s voice needs to be approximately 15 decibels louder than the background noise in the classroom for high speech intelligibility. This decibel difference is called the Signal-to-Noise Ratio - SNR. Comparatively, adults only require an SNR of 4 to 6 decibels. Research also shows that English as a Second Language - ESL learners need a greater SNR than those whose native language is English. In addition, sound field voice amplification systems enable teachers to spend the day speaking at a natural level, which significantly reduces voice strain and vocal fatigue. the Fewer elementary students referred to special education clAssrooM Higher scores on the Stanford Achievement Test, including reading, language, math, science, and social studies subtests connectIon Higher scores on Oregon’s Technology Enhanced Student Achievement test Increase in literacy test scores - Trost Amplification Study, Canby School District, Canby, Oregon, 2004 results of studies include: • Teacher absences due to vocal strain in amplified classrooms decreased from 15 percent to an average of 3 percent in one year. • Students in amplified elementary classrooms in Iowa displayed an average of 17 percent increase in overall on-task behavior. Students were found to be less distracted in amplified classrooms and required less redirection by the teacher. • Studies have also shown that teachers who use classroom amplification systems enjoy virtually unlimited freedom to move around the classroom while maintaining a stable acoustic environment. VoiceLift® Microphone Systems VoiceLift Microphone Systems are complete sound field voice amplification systems for any classroom. The VLS 1000 and VLS 2000 include all of the components necessary for a complete VoiceLift sound field system, including microphone, receiver, amplifier, speakers, and cables. Infrared Transmission The VoiceLift Microphone System uses infrared signals for transmitting the teacher's voice. Infrared microphone technology offers clear advantages over systems that use radio frequency, since infrared signals do not pass through walls and are not subject to RF interference. The VoiceLift pendant microphone runs all day on a single, rechargeable or standard alkaline AA www.extron.com battery and features easily accessible controls for volume and power/mute. An auxiliary input is also included for use with an MP3 player or other audio source, along with an auxiliary microphone input for use with an optional lapel microphone. Up to two microphones can be supported per classroom. The desktop charging station charges two microphones and protects them when not in use. The VoiceLift Microphone System is designed and manufactured by Extron Electronics and includes a three-year parts and labor warranty. Patent-Pending Flat Field™ Speakers The Extron FF 120 speakers included with VoiceLift Microphone Systems are full-range sound field speakers that feature Extron proprietary Flat Field technology. Flat Field technology allows the FF 120 to reduce beaming of mid and high frequencies directly under the speaker, delivering consistent sound levels across the listening area to each student. The FF120 offers an extraordinarily wide dispersion area of 170 degrees, which provides a very wide room coverage pattern. This is especially important for rooms with low ceilings. With the combination of Flat Field Technology and wide dispersion area, only two FF120 speakers are required in a standard classroom, as opposed to four or more traditional ceiling speakers. Easily Upgradeable to a Complete Classroom A/V System Extron is the only manufacturer who offers two upgrade paths to completely integrated A/V switching, control and voice amplification for the classroom — with no duplication or replacement of equipment. So, your technology investments provide not only the critical benefits needed today, but also a foundation for enhancing the system by simply adding selected components. Extron VoiceLift and PoleVault Systems allow you to make full use of your current equipment while also enabling you to take advantage of future innovations in classroom technology. VoiceLift Systems provide a seamless upgrade path to integrated audio, video and control in the classroom, making it easy to add multimedia capability in the future. At the heart of the system is the PVS 305SA which is an audio amplifier that also includes video switching capabilities. Simply add PoleVault input wallplates, a MediaLink controller, a projector, and A/V sources for a complete, easy-to-use classroom A/V system.

Every day, system designers face the challenge of integrating digital and analog video signals into new and previously-installed A/V systems. As digital video is associated with the cutting edge in A/V technology, there is an increasing desire by integrators and their customers to incorporate digital video into their systems. A wide array of digital video ports, including DVI, HDMI, DisplayPort, and HD-SDI, are present in some form on virtually every new component found in the market today. In addition, there is a very large installed base of analog hardware, as well as content, which must be kept viable even within new system designs. For the foreseeable future, then, most presentation environments will require mix of analog and digital video products and technologies. segments, DVI has been an established format since 1999. Continual evolution within the computer, broadcast, and now consumer electronics industries has brought digital signal connectivity to the forefront with the introduction of two, newer digital video standards – HDMI for consumer products and DisplayPort for computers and related technologies. LCD Monitor with Digital Inputs Digital Video-It’s More Than Just HDMI Although the DTV digital transition is currently headline news, digital video is not new to the professional A/V industry. The broadcast, teleproduction, and rental/staging segments adopted serial digital video, SDI, more than 20 years ago, and HD-SDI has been in use for more than a decade now. In the medical, visualization, and computer graphics The prevalence of these various digital signal formats presents opportunities as well as challenges for integration of professional A/V systems. DVI and DisplayPort are common to PCs and laptops, and are standard on many professional displays and high-end projectors. HDMI is primarily found on HDTV-capable products such as Bluray Disc players, game consoles, and satellite and cable DVRs and receivers. While designed for consumer and residential applications, some HDMI- equipped products are now being utilized in commercial applications as well. High definition digital video has also found its way into many applications beyond the broadcast studio as a means to capture, distribute, and display high definition content, extending into to house of worship and rental and staging environments. Just about every display available today has some type of digital video capability.

Why Digital? The implementation of digital A/V technologies brings the promise of several distinct advantages over analog technologies. First, for the manufacturers of computers and displays, there is the potential of removing a considerable amount of processing circuitry from a device. Since signals are already digital within the electronics of virtually all A/V products, most if not all analog-to-digital and/or digital-to-analog conversion can be eliminated, resulting in lower manufacturing costs and allowing for network operations centers often use a fully digital signal distribution architecture to deliver high quality, high resolution images. connectIon more competitive pricing. Second, in comparison to analog-based devices and systems, digital signals are by nature, lossless, enabling the distribution of pixel-perfect and consistent, pristine quality images while reducing the time and effort required for system and display set-up (see Figure 1-1). Finally, a digital infrastructure can be designed to accommodate the high resolutions commonly found today, such as 1920x1200 and HDTV 1080p, and provide support for the higher rates on the horizon. Making the Choice – Analog, Digital, or Both? Part and parcel of any transition are uncertainty, the fear of the unknown and desire to look for expert help and assistance in making decisions. In your role as an A/V IT manager, consultant or A/V system integrator, your customers are depending on you to help them make the best choices. In the face of a wide array of products and disparate technologies, customers want advice during the design and implementation phases to ensure that A/V systems meet their requirements for functionality and performance, stay within budget and, ideally, provide for future growth and further changes in technology. Complicating the decision is the knowledge that, while new A/V technologies and signal types are continually introduced, not all of them survive and the ones that do generally don't immediately replace the legacy formats. For example, many new digital source devices incorporate an assortment of analog video outputs, including composite video, S-video, and component video. Correspondingly, most new digital displays are still equipped with analog inputs. You might ask “why do manufacturers go to the extra effort, and additional expense, to provide a variety of connectors on their products?” In a word, compatibility. continued on page 22 www.extron.com 21 dIgItAl connectIon Digital Video for Pro A/V Integration Most manufacturers realize that sources and displays are rarely replaced at the same time. New sources, such as Blu-ray Disc players and higher-end laptop PCs, need to maintain compatibility with older displays. New, high-resolution flat panel displays and projectors, on the other hand, need to remain compatible with older sources, such as VHS recorders and DVD players that are retained for use with legacy content. System designs for typical training and presentation facilities, therefore, very often accommodate a hybrid mix of analog and digital capabilities, providing support for legacy analog video formats while incorporating newer signal types such as DVI, HDMI, DisplayPort and, in some cases, HD-SDI. To Get the Right Answer, Ask the Right Question The first question to be answered, then, is the most difficult, as it goes right to the core of the transition. Should you: • Stick with a tried-and-true analog design for the time being? • Build an digital/analog hybrid system that incorporates a mix of technologies? • Or, build tomorrow’s system today with an all-digital design and some provision for legacy analog products? — continued The System 208 D Supports digital and analog signals The answer, as with so many decisions and choices to be made, is “It depends.” Some systems are likely to remain predominantly analog for some time, with signal converters added as needed to accommodate new digital displays or source devices. For example, technology budgets for K-12 classrooms typically do not allow the wholesale upgrade of a media system simply to accommodate a new technology. Integrating a new, HDMI-equipped playback source, however, may require nothing more than the appropriate digital extender and a direct connection to the digital input on the projector. Others, such as in university lecture halls and corporate boardrooms, are beginning to incorporate digital video technologies on a broader, more systematic scale to accommodate the continuously evolving needs for digital media presentations while maintaining compatibility with existing stores of analog content and playback equipment. Digital input capability can be added by changing out the central switcher or scaler to one that accepts analog and digital signals; conversely, digital displays can be accommodated through the use of a switcher or scaler that outputs digital signals. Finally, specialized applications such as visualization, simulation, military and medical imaging, and command and control, are adopting a fully digital approach that can deliver uncompromised, very high quality, very high resolution images – one of the major benefits of digital video. These system designs are based around an all-digital switcher or matrix switcher, with any legacy analog sources accommodated through the use of an analog-to-digital converter. The bottom line is that, just as video replaced motion picture film and DVDs replaced VHS cassettes, digital technology in one or more forms will replace analog in the majority of applications over time. Typical corporate and educational presentation systems will move to a fully digital design in the future; for the time being, however, a hybrid system design that supports both analog and digital signals takes into account a wide range of presentation needs College/university Classroom 22 ExtroNews 20.2 | Summer 2009 dIgItAl and technologies and, in the long run, is the most prudent and cost-effective approach. Matching Technology to Need Before undertaking a system design, full knowledge of the customer’s needs and expectations are necessary. Once the primary question – analog, digital, or both? – has been answered, many more questions remain to be asked. • Is there a requirement for interoperability between digital and analog components? Depending on the source content, this may not be feasible due to digital rights management such as HDCP. • Is this an upgrade to an existing system? If so, is there a need to support legacy devices while providing the flexibility to address future growth capability? System longevity is also a key consideration in determining the appropriate product solutions. • Is the system expected to span a technology life of many years? If so, perhaps an all-digital infrastructure should be considered to support the continued evolution of video resolutions. System scope and size also determine operational practicality. Understanding the true operational requirements of any system during the design phase will help control potential cost overruns later. For example, if there are HDCP requirements, does protected content have to be viewable on all displays within the system, or only in a few, select locations? Having an operational understanding of a system will go a long way in meeting the needs as well as the budget of the customer. Going the Distance A/V professionals face three primary challenges in the handling of digital signals connectIon and the management of their distribution to ensure robust, reliable operation. The first is to maintain full signal integrity from source to destination. Digital video signals are considerably different in comparison to analog. Digital video signals do not degrade linearly as with analog video. For analog signals, the effects of cable-related losses worsen gradually with cable length, but for digital signals the impact is usually far more noticeable and abrupt, with sparkles, flashing images, or complete image loss altogether, as cable length increases beyond a “digital cliff” threshold. Technologies such as DVI, HDMI, and DisplayPort are primarily designed for short, point-to-point connections, for example from a computer to a desktop monitor, or from a Blu-ray Disc player to a flat panel television. Distances in these applications are relatively short and, in light of the very high data rates involved and a desire to Digital Signal Conditioning For DVI, HDMI, and DisplayPort, the proper “shape” of the RGB channels, also known as the “eye” pattern, is critical in ensuring proper image display. Losses in these channels will result in “sparkles” on-screen, or a complete loss of the image. They are attributable to long cable lengths, poor quality cables and terminations, and even certain source devices which output substandard digital video signals. Many Extron digital video products feature input cable equalization, which actively conditions incoming signals, applying equalization to help reshape and restore RGB channels to proper levels. The clock channel is also regenerated to provide proper RGB channel alignment. As shown below, a compromised source-generated DVI signal is significantly improved when Extron signal conditioning is applied. Input cable equalization reshapes and restores the “eye” patterns to ensure high quality images at the display. Without Extron Input Cable Equalization Direct DVI output from a source device. The signal quality is poor, and the "eye" pattern is significantly distorted. With Extron Input cable Equalization The same DVI output after Extron signal conditioning is applied. The "eye" pattern is fully restored. continued on page 24 www.extron.com 23 dIgItAl connectIon Digital Video for Pro A/V Integration — continued through conduit, digital signals can be converted and distributed using standard, shielded Category cable, or with fiber optic technologies.

Use of high quality, high performance cables can help to a degree and, in some cases, can provide for reliable signal transmission up to 75 feet (25 meters) or so. While suitable for most consumer applications, this distance limitation can have a serious effect on professional A/V installations where signals must be routed many tens if not hundreds of feet, from source to destination. In order to compensate for this limitation, signal conditioning products such as equalizers can be used to recover and restore a signal to distances up to 200 feet (60 meters). For even longer cable runs, or to accommodate the need to run cable Professional Digital AV System with HDCP Blu-ray Projector Flat Panel Display DVR Projector Flat Panel Display Projector Flat Panel Display 4x4 Matrix Switcher PC PC HDCP Source HDCP Repeater 1x4 DA Flat Panel Display HDCP Sink When sending signals from multiple sources to multiple destinations, it is important to select a/V integration products that are hDCP compliant and provide proper management of EDID communications. 24 ExtroNews 20.2 | Summer 2009 Second, there are very specific performance and timing parameter requirements that need to be maintained throughout the entire signal path. For example, in HDMI, the RGB video lines, or channels, must be accurately synchronized in order to be accurately handled and reproduced throughout the system. Terms such as equalization, jitter, and reclocking in the digital world replace the familiar level and peaking terminology of the analog world. Signal conditioning requirements for digital signals are also different and must be understood accordingly before designing a system. The third challenge in the successful integration of digital A/V systems is to be able to reliably switch, distribute, and route signals. Some digital video connections, including DVI, HDMI, and DisplayPort, require two-way communication between a source and a display. If this communication is interrupted, such as following a disconnection, source switch, or signal split, image display can be delayed, or even lost completely. In many cases, the content being used has a direct effect on this communication as well. For example, some early scaling DVD players with HDMI output did not allow the use of a repeater, and so the signal ended at the input of the switcher and was not passed through to the display. Minding Your EDID The two primary forms of two-way communication are EDID- Extended Display Identification Data and DRM - Digital Rights Management. Both are extremely important aspects of digital signal formats that can significantly impact system reliability if not properly accommodated and implemented. dIgItAl In brief, EDID relates to the communication of a display’s performance capabilities, such as its native and supported resolutions, to the source connected to it. EDID simplifies system setup, in that the display “tells” the source what pixel rate and resolution it prefers, and the source then outputs the optimum rate and resolution for the display, generally resulting in perfect images that are accurate on a pixel-for-pixel basis. DRM is the protection of intellectual property, of which HDCP - High-bandwidth Digital Content Protection is the most widely implemented. HDCP encryption is found on commercially-recorded Blu-ray Discs, high-definition digital satellite and cable television, downloadable content, and more. DRM is a primary concern in residential applications, where content piracy is of great concern to copyright holders, such as motion picture studios, who stand to lose millions of dollars if content is made available through unauthorized replication. For reliable presentation of protected content within a residential entertainment system, all relevant signal paths must be fully HDCP compliant and conforming to specific rules. This is relatively simple in the typical one-to-one scenario where a Blu-ray Disc player is connected directly to a flat panel display, but both commercial and residential A/V systems usually present the necessity of sending signals from multiple sources to multiple destinations (see Figure 1-2.) The primary difference, though, between residential and professional A/V systems, is the type of content that is being distributed and displayed on a regular basis. EDID 101 D EDID Minder connectIon HDCP in the Home The impact of a Gender Changer In a home environment, virtually all content is derived from commercial, copyrighted sources: movies on Blu-ray, satellite broadcast, or streamed across the Internet; games on Blu-ray, DVD, or solid-state memory; and sports or other live entertainment from pay-per-view satellite or cable TV sources. In order to protect the rights of the legitimate owners of this content, digital rights management in general, and HDCP in particular, will become common. Connecting two cables together for additional length is a very common practice in analog video and computer-video applications. The very high resolutions and signal frequencies common in digital video, however, are particularly susceptible to interruptions and discontinuities along the cable path. HDCP in the Workplace Content regularly used in professional A/V applications, on the other hand, is almost always locally generated. This mostly includes the display of Microsoft applications such as PowerPoint® or Excel; institutionally-produced video for training, demonstration, or sales presentations; and custom or proprietary software applications designed specifically for institutional operations or commandand-control needs. Very rarely is the content used in professional applications encrypted with HDCP. Typically, rightsmanaged content is limited to the occasional use of commercially-recorded materials, for example when a sales manager wishes to “rally the troops” by playing a scene from his or her favorite movie. With digital signals, something as simple as the insertion of a coupler or gender changer between two cables can cause reflections which seriously degrade the signal. Consider what happens to a high resolution digital signal when it’s passed through two 6' (1.8 m) DVI cables connected female-to-female coupler. DVI Female to Female Adapter 6 ft.

Applications Really Are Different The key is to select digital products based on the day-to-day requirements of the application for which the system is being designed. In all applications, proper management of EDID communications is a must. For residential applications, compliance with a DRM scheme such as HDCP is also mandatory for all system components. And for commercial applications, DRM must also be considered within the system design to allow the occasional use of commerciallygenerated content, but may not be necessary for all system components or When planning digital video systems, it is important to take into consideration signal interconnections and other design factors. Select signal routing and distribution products, including switchers, matrix switchers, and distribution amplifiers, with features such as input cable equalization, output reclocking, and other signal conditioning capabilities that help accommodate specific design challenges that may compromise digital video signal integrity. continued on page 26 www.extron.com 25 dIgItAl connectIon Digital Video for Pro A/V Integration for every signal path within the overall system design.

By Eric Mendenhall, Director of Audio and Power Systems Extron Power Supplies: How We Design to Be the Best B ecoming the best at power supply design is much more than using the right components or applying exhaustive testing schemes. Designing the “best” of anything is a commitment to a strict no-compromise philosophy. In the case of power supply design, that philosophy must be founded on reliability over cost or features. Reliability implies efficiency; efficiency leads to meeting green objectives. In this article I would like to share with you a few recent developments in power supply design, coupled with an inside look into how we design power supply systems to be reliable and sustainable. Linear Power Supplies To understand the significance of the term “switchmode”, we should first investigate the prior power converters that did not operate in this way. Typically these are called “linear,” but again there is some discrepancy between the term as used colloquially and the types of converters to which it applies. First let’s investigate what Figure 1: Line Frequency Fig Power 1Fig Supply 1 we meant by the conversion of power into something more useful to the electronic circuits in the products we make. A typical But there’s a catch, of course, actually AC mains voltage is 120 Volt AC 60Hz several of them. This simple converter sinewave, whereas the electronics may lacks line regulation, meaning that if require +5 Volts DC and -5 Volts DC for the AC mains voltage sags by 15%, video circuits, or +80 Volts DC, and -80 then so do all of our output voltages.

Obviously Maybe our circuits will work anywhere we need to scale the voltage and provide in that range, and maybe they won’t. multiple outputs, but we also need to And if the line voltage doubles from provide electrical isolation from the AC 120VAC to 240VAC, then theoretically mains for safety reasons. A transformer is the output voltage would double, but a very useful device that provides electrical practically speaking we would have to isolation, scaling, and multiple outputs use a different transformer. Universal Control all at once, but it only works with an AC input is much more difficult to achieve, Control signal. Transformers just can’t pass DC and typically the voltage range must be for reasons we won’t get into here. Since selected or configured at the factory. We we already have an AC voltage on the can add a regulator to make sure that the Fig 3 AC mains, it’s a simple matter to use a output voltage does not change if the AC Fig 3 within limits. This transformer as an AC to AC converter, then line voltage fluctuates follow it with some simple diodes to provide can be accomplished with minimal effort an AC to DC conversion as shown in by adding a “linear” regulator (as shown Figure 1.

In Figure 3, this is done by rectifying the line frequency AC to DC, then using Fig 1 active power electronics to create a high frequency AC to pass through the transformer, after which it is rectified to DC again. This results in a great reduction of size and weight. Fig 1 t HARD Intrinsic Capacitance Transistor Ref.

Traditional designs often require the mounting of a transistor to a dedicated heatsink. This then requires a thermal insulator and a nut and screw combination for mounting. Then some type of locking nut must be used. Due to repeated thermal expansion and contraction, a compression washer must be used to ensure proper force is applied. To maintain electrical isolation, a shoulder washer is used. All this mass is then affixed to the circuit board somehow (as shown in Figure 8), but it can be susceptible to shock and vibration, causing broken leads. Screw Washer Insulator Insulating Bushing Insulating Bushing Plain Washer Nut speAkIng... Device Operating Temperature and Life Expectancy All the efficiency improvements result in lower power draw, but the benefit of increased efficiency goes much farther than that. Heat accelerates component aging; a cooler product lasts longer and is more reliable. The general relationship is a doubling of lifetime for every 10˚C temperature reduction. The benefits of high efficiency are seen as reduced failure rate and increased life expectancy. Power Factor Correction Power factor is another area that received a lot of attention from a worldwide compliance perspective in the last 20 years. It has been made mandatory in Europe for all designs over 75 Watts in many product categories. Power Factor is simply Watts / Volt x Amperes. For a resistor, Watts = Volts x Amperes and power factor is 1.00. In the case of a simple line frequency rectifier, current can flow only when the input AC sinewave peaks exceed the DC voltage on the capacitors, leading to high current spikes at the waveform peaks and large Heatsink Spring Washer TraDITIOnaL DESIGn 120VaC Figure 8: Thermal management simplification Fig 7 A more robust approach involves using surface mount power transistors and diodes, and using the PCB copper area for a heatsink. If the dissipation is low enough, this approach removes all hand labor and human error from the process, leaving just the highly mature and reliable process of a solder interface with a low profile result that is much less susceptible to shock and vibration. 30 deadbands in between. The spectrum of the resulting current contains harmonics of the line frequency, which increases the total current draw, but can deliver no real power. The current is drawn from the line effectively sent back without delivering any total power. Of course this increased current draw creates a very real load on the AC system wiring, which must be sized for the Volt x Amperes, rather than the Watts. In typical designs of linear or switchmode power supplies the power factor can be in the 0.5 to 0.7 range, meaning that the current draw is 50% to 100% higher than required by the power consumption. A technique called power factor correction is used on more sophisticated designs to improve the power factor to close to 1.0 , which reduces the current draw to just that required for the power draw as shown in Figure 10. Although this does not improve efficiency in the power supply, it improves system efficiency through the AC mains back to the generator. Once again, this comes at the expense of increased cost, complexity and design resources, and high reliability can only by achieved with very careful attention.

Energy Star Electromagnetic Interference (EMI) EMI is a concern in switchmode power converters to a far greater degree than it is in linear supplies. A switchmode circuit operating with 60kHz square waves produces harmonics easily up to the 60MHz region in the form of electrical noise, electric fields, and magnetic fields, which can interfere with operation of the very circuits that the power supply is supposed to be serving. These harmonics can also exit the product via cabling acting as unintentional antennae, or openings in the chassis. Once in the outside world, they can interfere with all types of equipment. The last 20 years have seen an industry-wide focus on compliance as regulating www.extron.com T 60Hz T 180Hz 300Hz 360Hz 420Hz 480Hz 540Hz 60Hz 180Hz 300Hz 360Hz 420Hz 480Hz 540Hz (a) (b) Fig 9 Figure 10: (a) Without Power Factor Correction; (b) With Power Factor Correction bodies worldwide have been created or strengthened to deal with the problems of electromagnetic interference. Early designs were notoriously noisy from an EMI perspective, but again, companies were able to rise to the challenge and produce switchmode designs effectively as quiet as the old linear ones while retaining all the benefits. Conclusion Reliability is a primary concern of professionals, whether they are customers, system designers, or product manufacturers. At Extron, we have adopted the philosophy regarding power supplies for our products that reliability is our primary objective, not cost, not power density, not specsmanship. To achieve this, we start with a highly efficient topology made from the highest quality components available and manufacture it with the same process used for our high-end video products, using the same care and attention to detail in every step of the process. From Purchasing to Manufacturing, from Test Engineering to Quality Assurance, Extron switchmode power supplies ensure more high quality Extron products. Waste Heat vs Load 6.0 Waste, W Energy Star is a voluntary public-private partnership that sets energy efficiency standards for a growing number of product categories. One type of product covered is the External Power Supply, also called a Desktop Power Supply. These are the plastic cased units that power so many consumer and professional products with low unit power but enormous aggregate power. The limits for Energy Star in a Desktop Power Supply are a function of the power rating of the supply; they include idle power and average efficiency. Average efficiency is simply the average of the efficiency measured at 25%, 50%, 75%, and 100% of rated load. The limits are difficult to satisfy and present a significant design challenge. Whereas typical Desktops may have an idle power of 2.0W, an Energy Star Desktop is allowed just 0.3W. Efficiencies may be improved from just 70% on a non-Energy Star unit to 85% in an Energy Star unit, meaning waste heat has been cut in half. Although the numbers may seem small at first, the Watt-hours saved add up quickly over the course of a year, especially considering the high volumes of Desktop Power Supplies sold. 5.0 4.0 3.0 2.0 1.0 0.0 0% 25% 50% 75% 100% Load Traditional 12W Desktop Supply Extron Energy Star 12W Desktop Supply Figure 11: Comparison of Traditional versus Energy Star Power Supplies 31 NEW PRODUCT HIGHLIGHTS Complete product brochures at www.extron.com TLP 700MV TouchLink™ 7" Wall Mount Touchpanel The Extron TLP 700MV TouchLink 7" Wall Mount Touchpanel is designed to mount securely into a wall, lectern, or other flat surface.
