Ultimate in AV
By R. David Read
Luxury car maker BMW goes into technology overdrive.
|The overall BMW complex as viewed from an adjacent TV tower. The Conference Center is the glass-roofed building to the right; the teacup-shaped structure to the left houses the BMW Museum.
World-renowned automotive manufacturer BMW recently opened an impressive new conference center at its Munich, Germany, headquarters. The BMW Towers, constructed in 1972, have become a landmark for the residents of Munich, and an acclaimed architectural icon in international circles. At the time of the original construction, a three-story portion of the tower’s base was dedicated as the computer center for the BMW enterprise. With the advent of PC-based computers and the subsequent obsolescence of large, real-estate-devouring mainframe computers, the space became available for alternate development. BMW decided that the underutilized space would be suited for a new conference center.
Conceived in 2003, the conference center was completed in late 2006 and fully commissioned in early 2007. The AV portion of the project was designed and installed to incorporate the latest in media technology, with a system price reported to be in the neighborhood of $2.25 million (USD).
The overall project was handled by Hamburg, Germany-based architectural consultant ASP Schweger Assozilierte Gesamtplanung GmbH; the consulting firm for the general building equipment was IC Ingen-ieurconsult GmbH, based in Frankfurt; and the AV and conference systems were designed and planned by the Cologne-based proAV Consulting.
The AV installation job was awarded to Munich-based c-line Medien-systeme, in cooperation with VAV Vertriebs GmbH, based in Landsberg, Germany; VAV Vertriebs GmbH took responsibility for the media control issues.
The new conference center is housed in the rectangular, three-story building to the right of the main towers. The lower floor is devoted to the restaurant and offices; the second floor houses 29 conference rooms and the main conference hall. The conference hall reaches up to the third floor, enclosed by the building’s glass roof. Additionally, 16 smaller conference rooms are located directly in the tower, one each on most of the floors. The conference center proper encompasses about 55,000 square feet.
The main conference hall on the second level is comprised of a 60'x82' space that can be subdivided into two sectors for simultaneous events. In combined mode, the space can accommodate an audience of 300 people, depending on seating arrangements.
When used in separate room configuration, the two rooms are divided by a massive, high quality, movable wall system designed to guarantee excellent sound isolation. The wall also contains sensors that trigger the AV control system(s) for configuration into either the combined or divided mode. The retractable wall parts are completely hidden in the structural wall cavities.
At the owner’s insistence, the interior walls and the skylight-equipped two-story ceiling of the main conference room were constructed with aluminum walls and a glass ceiling to replicate, and complement, the exterior motif of the towers. It was also dictated that the floor be constructed of wood parquet. HVAC noise did not escape the owner’s attention: It was mandated that such noise be held to an absolute minimum. These directives resulted in some interesting acoustical considerations and development of some unique corrective techniques.
The Halsterbak, Germany-based architectural-acoustical consulting firm of Taubert and Rube GmbH performed the acoustical design for the space. Fittingly, for a room of this size and use, a targeted reverberation time of about 1.1 seconds with chairs was deemed appropriate. Subsequent, as-built measurement data confirmed compliance with the selected design criteria, having a measured average reverberation time of 1.05 seconds.
The relatively short reverberation time was accomplished, in part, by using a special material for the wall surfaces. The material chosen for the lower half of the room has an aluminum-like surface that is perforated with slits (20% opening) and an interior fill of acoustic fleece. Aluminum-clad material is employed on the upper surfaces.
As noted, the ceiling is completely comprised of skylights to emit natural daylight. This type of surface presented two adverse conditions: glare from the sunlight and accompanying acoustical reflections. To resolve these conditions, vertical “blinds” were designed both to diffuse the natural sunlight and provide a surface for the incorporation of absorptive material for acoustical treatment. The “blinds” are perforated and filled with sound absorption material.
Even in an unoccupied state (without chairs), the hall has acceptable speech intelligibility measured at 0.62 STI1; the same conditions exist in both the combined and divided modes. STI tests were accomplished using standardized methods as prescribed by ECO IEC606282.
To minimize air-handling noise, they used under-floor plenum duct. In this type of HVAC system, the supply air is provided to the room space through a multitude of floor-mounted supply outlets, and return air is “sucked-out” by vents dispersed about the room, located near the ceiling. Air-handling noise is reported to be barely perceptible. Moreover, the floor-mounted supply air ducts were also put into service as convenient locations for media connection boxes, as described later.
The owner’s stipulation that the conference room be capable of being divided into two equi-dimensional spaces required that the video projection system be able to serve the combined room or each separate section. The result was three interrelated, but operationally distinct, systems. Neither room is considered to be subordinate to the other; hence, both must function equally.
To accomplish this complex switching arrangement, a Vista Spyder projection system was specified. This system forms the “heart” of the projection system control, and (as of this writing) is one of three that have been installed in Germany.
In combined mode, soft-edge, seamless video images are cast by three Barco SLM R12+ 12,000 lumen projectors onto a 38'x18' screen mounted on the front wall of the combined rooms. The projectors and the associated main screen are combined into a single viewing area with the rooms configured into combined mode. A major challenge to the systems integrator was finding a way to move the 38-foot-long screen, weighing about one ton, into the room.
In divided mode, the second room is equipped with a smaller, separate screen. In this case, both rooms are equipped with additional dedicated Barco SLM R12+ projectors, each of which is driven by Centrix CTX8022 video processors. A dedicated “divided-mode” projector is mounted on a projector lift; another is located atop the center projector of the three-fold soft-edge projection system for use in the de-combined mode.
The projection equipment is located in three projection booths integrated into the rear wall of the room. These booths are completely closed, sealed and conditioned with an independent, closed-loop HVAC system. Furthermore, the booth’s apertures are equipped with a special optical glass normally used for high-quality optical devices, to ensure maximum image quality.
The soft-edge projectors are driven through a DVI glass fiber interconnection directly from the Spyder processor for highest image quality. Transmission backup is provided by a Magenta Research twisted pair Cat6 connection hooked to the RGBHV of the projectors.
As stipulated by the design criteria, the entire system can be used in “automated mode” for less critical situations, or configured for full-fledged manual control. In “automated mode,” all control devices are hidden from the audience, and system control is exercised by means of presenter-available wireless touchscreens. In this configuration, a presentation is a simple matter of connecting a PC to a floorbox or by using built-in Media-PC files loaded by the network or USB.
Thus configured, the presentation is in a “GO” condition without further intrusion by a manual operator. Although one might imagine that a less-than-proficient presenter might have a problem operating the system, even the soft-edge projections and associated fades and multi-level projections can be accomplished by using preset templates.
Manual Control Option
In a more practical sense, when more complex presentations are involved, the Spyder controller is controlled manually for full-system flexibility. Under these conditions, the control desk is moved into position at any convenient location on the floor and connected to any available floor-mounted connection box.
Once connected, different signals, be they HD, DVI, RGBHV or S-video, are routed to the four input channels of the Spyder system and handled internally in the “six million pixel pool.” Thus available, the signals can be changed, moved, resized, blended and morphed as required. The four system outputs are used as three DVI outputs for the soft-edge projection, and one RGBHV output is used as the control for dual image monitor and preview purposes.
This control signal is transported via Magenta Research equipment over Cat6 to any floorbox where the control PC is positioned. The control PC also communicates with the system via Ethernet over Cat6. As designed, only two Cat6 patches are required to initiate the complete multi-image projection control from any location.
For maximum image quality, the primary PowerPoint PC and DVD players for each room half are located in the user-accessible wall rack for direct cable connection to the Auto-Patch Optima matrix and the Spyder multi-image processor without any compromised signal transmission over Cat6 cables.
All other PCs used for presentations are connected via the Crestron QuickMedia interfaces installed in floorboxes.
From the beginning, the building had seismic problems, due to a metal stamping plant creating BMW car bodies in the neighborhood Many vibration absorbers were integrated into the building during construction; after the redesign, these were reused in the floor of the conference hall.
Jitter Still Existed
Despite these provisions, as work progressed on the installation of the 3500x 1050 pixel soft-edge projection system, it was noted that a severe jitter could still be seen in the images. Clearly, this was an unacceptable condition.
Schorndorf, Germany-based Zuckriegl Engineering GmbH, an acknowledged expert in seismic conditions, was called in for consultation. Initial studies favored a system comprised of one complete support system for all three projectors. However, additional tests and simulations determined that the initial proposed solution would not be acceptable because the ground was found to be oscillating in all directions.
The preferred, and final, solution took the form of installing supports (weighing about 1100 pounds each) for each individual projector treated as a single independent unit. As installed, the solution worked admirably and the viewing surface is devoid of any perceptible motion. (See sidebar, “Seismic Conditions.”)
Little traditional AV cable is installed in the floor. The exception is high-quality coax for HD cameras, a pre-installation for remote camera teams connectable through the floorboxes, the delegate conferencing system, power cables and a limited number of microphone cables for direct connection to the rackmounted A/D converters. All other cable is Cat6 and glass fiber. Signals are transmitted through Crestron QuickMedia (QM) for PC connection, Magenta Research MultiView transmitters for high-quality RGBHV video transmission and through EtherSound for the digital audio.
An interesting feature is that all AV equipment is mounted into the .24-inch double-walled enclosure space that surrounds the entire hall, thus rendering all equipment invisible to the audience. Even the mixing consoles were designed with tiltable frames so that, even when operating, they can be concealed in the wall cavities.
The consoles are also provided with mobile bases, permitting them to be wheeled into the audience spaces when operator control is deemed essential. Three 19-inch-wide, 79-inch-high racks plus one accessible rack for players, Media-PC and touchpanel chargers are installed in each of the half-rooms.
Racks Are Concealed
The wall-mounted racks are completely concealed and can be accessed only by operating the hinge-mounted entire wall-part. If used manually, the mobile mixing boards must be taken out before an event starts. If no further mobile technique and no further manual control is required, just the lid of the smaller rack is opened; the touchpanel is taken out and the presentation can commence.
All racks are interconnected and function as one complete system when the room is combined. As noted earlier, contacts on the movable wall elements indicate whether the room is combined or divided. Depending on the room mode, the Crestron media control system automatically adjusts the control setup and recalls the correct touchpanel screens and the proper setups and presets in all other devices.
Another rather ingenious approach was used for the media connection floorboxes. As noted, the auditorium floor is constructed of wood parquet, and a large number of supply-side air conditioning vents with perforated cover plates designed to match the wood parquet are mounted in the floor. Twenty-four of these boxes serve a dual purpose, inasmuch as they are also used as media connection floorboxes.
Digital Audio System
Each hall is equipped with a digital audio system that can be combined for full-room occupancies. The digital audio is based on one Yamaha DME-64 matrix for each room, connected to each other by a Yamaha cascade cable and equipped with the appropriate interface cards. An associated Ether-Sound distribution system allows connection of the two Yamaha mixing boards (DM1000 and O2R96, equip-ped with the AuviTran AVY16-ES interface card) at any location in the hall by simply connecting the Cat6 cable to a convenient, readily accessible floorbox.
The only analog audio connections are the microphone cables from the floorboxes to the wall-rack-installed Yamaha AD8HR, eight-channel A/D AES-EBU interfaces and the wiring between the Yamaha DA824 D/A AES-EBU interfaces, the power amplifiers and other outgoing connections (see the accompanying block diagram).
The EtherSound network is used for interconnection of the mixing boards with the DSP matrices. The mixing boards are partly automated; hence, they can be placed in their “park position” in the wall cavity while still activated. If manual control is required, the mixer(s) can be moved to a different location. To accomplish this, the Cat6 patch is disconnected, the desk is moved to the desired location and connected to an associated floorbox Cat6 connector, and mixing can commence. Actually, nothing in the signal chain is changed; just the EtherSound connection is routed over some alternate patch points.
For the hardwired microphone connections, 16 Shure MX418 gooseneck microphones with base plate are available. In addition, 16 Sennheiser wireless microphone channels with hand-held mics, lavalier and head-worn mics were provided, and can be used in the combined room or in either of the divided rooms.
Within each mobile audio mixing base, and beneath the board, an additional Shure SCM 810 E automatic microphone mixer is installed and connected through the direct outputs of eight microphone channels on the board, with its sum fed back to one input channel of the board for convenient half-automated microphone control. All other input and output connections on the mixing boards are handled by the EtherSound interface, with no need for additional analog cables.
Each room is also equipped with an installed Marantz PMD 570 digital audio recorder for fast audio recording to MP3 or other digital formats on a removable Compact Flash card. The recorders can be activated by pushing a button on the wireless touchpanel.
The sound-reinforcement system for each half-room incorporates three Kling & Freitag CA 1215-6 compact loudspeaker systems on custom-made mounts for left-center-right. Another 10 Kling & Freitag CA-106 surround-sound loudspeakers and two Kling & Freitag SW 115D-XO subwoofers are concealed behind the “slit-walls” around the hall. The surround-sound setup is engaged only in the “combined” mode of the hall. Power amplifiers for the main loudspeaker systems are Bittner XR-1500s and, for the surround-sound system, one eight-channel Bittner 8X200 power amplifier is used. Additionally, for monitoring purposes on conference tables or lecterns, several Meyer MM-4 miniature speakers are available for portable use.
The earlier-mentioned high speech intelligibility of 0.62, measured in the complete empty hall without chairs, was measured through the Kling & Freitag main sound-reinforcement systems and is testimony to a high-performance, high-quality loudspeaker system having accurate coverage control.
The Kling & Freitag loudspeaker systems normally require a specific controller to provide proper equalization. In support of this project, Juergen Freitag of Kling & Freitag supplied all information to create the speaker alignment curves within the installed Yamaha DME processors. Tobias Foerster, of c-line Mediensysteme GmbH, was responsible for the audio and sound-reinforcement system. He applied painstaking attention to the proper time alignment of the loudspeaker system in interaction with live video feeds, particularly as it concerned the inevitable delay of live video signals introduced by digital processors.
The design and installation process also included a multi-channel translation system: IR transmitted to attendees.
In three remote rooms, floorboxes were installed for two monitors (PC image and camera image) and two translator desks with headphones. The translators hear the sound within the Bosch DCN conference system or they can monitor the sound from any microphone used in the hall(s). The translator workplaces are removable and are installed only prior to an event when they are required. Installation time is less than 30 minutes.
Charging boxes for the 112 small, mobile IR receivers with headphones normally are located in a different equipment room; they could have been installed into the double wall enclosure space, but this would have made the daily handling too complicated.
Isolated by a coax switching unit, mobile IR transmitters on stands are also available for use in the foyer. These can be used in the case of open events where the foyer is included in the hall’s activities, such as pre-event situations, for example.
Fifty microphone stations of the Bosch DCN digital conference system can be connected to designated floorbox outlets and can be used in any combination, depending on the temporary table and room chair setup. The microphone stations are equipped with a headphone output that allows each participant to listen to the translation channels directly, without need for an IR receiver. Using the combined hall or the first half divided hall, a Tandberg 3000 MXP videoconference unit is available to connect a remote lecturer online into a conference or meeting in the hall. The video signal is also fed to the Spyder processor to integrate the far-end picture into the displayed multi-image content. The camera is installed below the center projector behind the optical glass window.
Conference Hall Control
|Videoconferencing is handled in the smaller conference rooms with portable setups.
Each half-room is equipped with a Crestron Rack2 with all necessary control boards. The two half-room units are interconnected via Ethernet and are also connected to a general control computer located on the same floor. This control computer was installed with Crestron’s RoomView software and, for maintenance purposes, keeps track of all conference rooms in the building.
In addition to the wireless touchpanels in each room, a second wireess touchpanel is available for use at the central control location if, and when, required. Therefore, four Crestron TPMC-10 touchpanels are available with wall-mount and table-mount chargers.
Eight QuickMedia receivers are installed in floorboxes (four for each half-room) and four portable receivers are available for the control positions in the hall, thus allowing connection of any portable PC or notebook by the presenter or the technical operator. The QuickMedia receivers are managed by QuickMedia 8x8 and 4x2 matrix switchers.
To accommodate the media, the ceiling is equipped with a full lighting system using 18x ARRI daylight Fresnel lamp fixtures deemed appropriate for TV lighting purposes. These are used in the combined mode of the hall. Daylight lighting is essential because the skylight windows are intended to be used as much as possible, and light will be mixed. But, if necessary, the windows can also be covered by horizontally moving motorized blinds.
Each lighting fixture is affixed to an individual, adjustable mount and positioned underneath the cover material and tied directly to the concrete beams between the skylights.
In similar fashion to the AV equipment, lighting control hardware is also integrated into the walls, but at the opposite side of the room to avoid any RF interference. The lighting control desk is installed in the lighting rack; however, it is capable of being controlled remotely by the Crestron system and can be accessed from any of the touchpanels.
All smaller conference rooms follow the same guidelines as the main conference hall and primarily use Cat6 cables only. All media connection is handled by Crestron’s QuickMedia and IMedia interfaces, integrated in tables and portable connection boxes. All equipment is controlled by Crestron TPS-1700 six-inch touchpanels.
The Hitachi CP-SX 1350+ video projectors can display SXGA+. In view of this high resolution, specially designed projector mounts with 60-pound balancing weights temper the seismic oscillations in the building.
Some of the rooms have motorized projection screens but, wherever possible, ML Audio flat panel loudspeakers were used along with custom-made projection paint, for an unobtrusive room design. The larger rooms have an equipment rack in an adjacent preparation room. In smaller rooms, the equipment is installed in a rack hidden within the suspended ceiling and controllable via touchpanel only.
Four Media Mobiles are available with 50-inch plasma screens with interactive SMART Whiteboard Overlay, a DVD player, media PC, TV tuner and wireless microphones. Also, two AV conference mobiles are available, and can be connected in some of the rooms. These mobiles are equipped with a Tandberg T 990 MXP videoconference system with a 50-inch plasma display.
Press feed distribution audio and video transmission cabling was provided to an exterior connection box located at the nearest street position for TV trucks. This connection box is equipped with a full set of glass fiber cables for HD transmission (both single-mode and multi-mode); triax for “old-fashioned” cameras; connection for digital audio; and all other necessary items, plus power for TV production trucks and supplemental vehicles.
With careful planning, close collaboration with BMW staff members and meticulous attention to detail, the project was delivered in accordance with the owner’s wishes. Reports indicate that the installed systems are functioning in the desired manner.
1. ECO IEC60849 dictates that an acceptable STI of .5 (on a scale of .01 to 1.0) is required for buildings of public occupancy.
2. The conference room system we are detailing here is not used for life-safety evacuation. A totally separate audio system was installed for this purpose, completely apart and under separate contract from this system.
3. For the BMW project, proAV Consulting was engaged as the AV designer by IC Ingenieur- consult GmbH of Frankfurt, Germany, which had responsibility for the design of the general technical building equipment.
As noted in the text, due to unacceptable vibrations that were affecting the video projection system, Zuckriegl Engineering GmbH was called in for consultations. Comments from Mr. Zuckriegl’s report:
“The vibrations of the slab at the installation area were measured. They were in a range of v = 0.25mm/s up to v = 0.60mm/s. Such vibrations are easily perceptible and can impair the system performance.
“The vibration displacements were in the range of x = 0.004mm up to x = 0.009mm, with a dominant frequency at f = 11Hz. This frequency is the natural frequency of the slab, so the spectrum shows the response of the slab to the broadband foot-point excitation (Figure 1).
“At first, such vibrations seem to be too low to affect a projection system. But a temporary test installation on a rigid block with 1m height showed that the projection can be distorted. The vertical vibrations cause a twisting angle of the beamer, which depends on the geometrical behavior of the vibration mode and, if the support is not rigid, to the resonance amplification of the beamer-support system.
Frequency response spectrum analysis.
“The preliminary investigation for this situation showed that, in this case, the twisting angle will be the sum of geometrical circumstances and the resonance response, in red in Figure 2.
“The first favored version with one complete support system for all three projectors was abandoned after detailed simulations. It would still have created too much oscillation because the ground was oscillating in all dimensions and a sufficient stiff substructure could not be realized in the narrow field conditions.
Projector beam deflection resulting from vibrations.
“The conclusion was that the best version would be the individual treatment for each projector mount as a single independent unit, consisting of a combination of a stiff substructure for the beamer (‘beamer-tower’) with a vibration isolation system (Figure 3).
“The beamers were mounted on a steel platform, which is the inertia mass at the same time. Underneath, damped steel-spring-isolators are arranged, symmetrical to the center of gravity. This isolated platform is supported by a stiff structure, with horizontal natural frequencies well above f = 25Hz to limit the resonance effects.
Projection mount construction detail (dimensions in mm).
“The solution worked and the viewing area is devoid of any perceptible motion.”
Based in Cologne, Germany, proAV Consulting’s expertise is in the planning and designing of audiovisual installations for the corporate market. In addition to this BMW project3, proAV Consulting recently collaborated with Sono Studiotechnik of Munich, Germany, to complete the commissioning of the new headquarters building for the China National Petrol Corporation in Beijing, China. The Beijing project involved the planning and design for videoconferencing and AV networking for two conference rooms and more than 40 interconnected board and meeting rooms.
Because Bernd Noack, principal of proAV Consulting, was involved in live sound and touring for nearly 20 years prior to establishing the company in 2000, it is not surprising that the firm also focuses on audio and acoustical design projects. A major project, completed in 2007, involved an acoustic enhancement system for the Opera House in Tel Aviv, Israel.
proAV Consulting worked in cooperation with the architectural-acoustical consulting firm of Benny Brookstein Ltd. of Tel Aviv and systems integrator Barkai to provide a system that, in their words, “Greatly extended the artistic potential of the house, thus making it fitting for opera and speech, as well as for orchestral symphonic music. The subsequent result [of the installation] was that the facility now has a much greater performance range.”

c-line Mediensysteme GmbH
Munich, Germany-based c-line Mediensysteme GmbH was founded in 1996 by Stefan Wohner and Dieter Scheloske, who sensed an opportunity in the emerging integration of media and communication markets. As early proponents of AV/IT convergence, the firm’s founders soon found themselves involved in designing and providing media and conferencing systems into existing IT infrastructures. Initially, the two-man team started introducing VTC systems through ISDN telecommunication lines. As technology evolved, they moved ever closer to the direct integration of videoconferencing and multimedia with IT networks.
c-line’s first major projects included high-tech, executive boardroom systems for such internationally recognized companies as Allianz, BMW, Rolls-Royce and Siemens. At Siemens, c-line installed a conferencing and presentation system that enabled its headquarters to connect with its worldwide offices and subsidiaries.
As c-line’s client base and reputation grew, so did the company. Today, c-line engineers are recognized specialists in equipping large presentation spaces with multi-screen projection and sound systems, translation systems and complex media control systems.
c-line now has a staff of 25 and is growing continuously. Wohner stated, “Our objective is to keep our eyes on the future and to focus our attention on the harmonious integration of videoconferencing and multimedia components into any corporate IT infrastructure of today—or tomorrow.”
