KEDGE Business School in France is one of only 58 business schools worldwide to have earned

triple accreditation of EQUIS, AMBA, and AACSB for MBA programs. The school is committed to

creating new modes of teaching and instilling responsible management practices for the Wine and

Spirits industry. To support a growing student body, KEDGE built a new state‑of‑the‑art lecture

facility at their Bordeaux campus. They teamed with AV integrator Triaxe Audiovisual Professionals

to implement the high performance AV switching and distribution solution designed in consultation

with Extron application engineers. The enterprise‑wide AV system included Extron IN1608 scaling

switchers for in‑room presentation and an XTP Systems® design to link the lecture halls.

“From project conception to realization, it was a great adventure that included evaluating a huge

variety of AV equipment for the new building,” says Eric Renelleau, Audiovisual Technician at KEDGE

Business School, Bordeaux Campus. “Extron’s IN1608 switcher is a perfect fit for the lecture halls,

and the one XTP System ties all of our halls together.”

Building InstallationThe new building features 11 lecture halls that range in size from 80 seats to 500 seats, 42 classrooms,

five IT labs, and four meeting rooms. Extron XTP DTP 24 shielded twisted pair cable provides the

infrastructure for signal transmission between IN1608 presentation switchers, XTP® matrix switcher,

and associated transmitters and receivers. Its quality construction and shielding protection ensured

optimal performance and reliability in supporting the long transmission distances throughout the

various lecture halls and meeting spaces. “The economic value and demonstrated performance of

the XTP cable pleased the KEDGE representatives, and the installers

appreciated the quick and easy termination possible with this cable,”

says Patrick Corthondo, Sales Director at Triaxe.

Each lecture hall provides a standard selection of local sources such

as a Blu‑ray® player and document camera, digital and analog AV

connectivity for portable devices, and a high performance projection

system that makes use of Christie DHD775‑E  HD DLP projectors.

Classrooms include an EPSON BrightLink  485Wi Interactive WXGA

3LCD Projector. The 500‑seat lecture hall and one of the 160‑seat

halls provide two projection systems for added versatility and optimal

viewing conditions throughout the venue. Display resolutions are

standardized to 1920x1080 in the lecture halls and 1280x800 in the

classrooms. Also, a videoconference system making use of the Lifesize

codec is integrated into Lecture Hall 10, supporting shared instruction

with remote sites as well as enabling collaborative sessions between

students or colleagues.

IN1608 Scaling Switcher for All In-Room PresentationsThe Extron IN1608 Eight Input HDCP‑compliant Scaling Presentation

Switcher provides AV signal routing within each lecture hall. The team

selected this particular switcher because it included all of the desired

functionality in a single enclosure. These included high performance

scaling for HDMI and analog video sources, local and remote AV

signal distribution, and simultaneous video output to drive up to three

display devices. The IN1608 features four HDMI and two universal

analog video inputs for local equipment along with two DTP twisted

pair inputs for long distance transmission from in‑room floor box

locations. In addition to general source and display connectivity, the

inputs and outputs were also utilized to provide connection to and from

a centralized XTP System. The built‑in IP Link® Pro control processor in

the IN1608 was used in conjunction with Extron MediaLink® controllers

to provide in‑room control of the AV system, while the Ethernet port

was tied back to the Control Room to support remote monitoring and

control.

In Lecture Halls 9 and 10, an HDMI input and output on each of the

room’s two IN1608 switchers were interconnected to allow content

sharing for maximum flexibility in the dual presentation spaces. The

ability to remotely power DTP transmitters and receivers reduced

requirements for power drops and further streamlined the system

design within each lecture hall.

VideoHDMI signals from in‑room floor box locations are extended to the

IN1608 using the Extron DTP HDMI 230 Tx transmitter. A low‑profile

receiver is mounted with each video projector, accepting scaled

images directly from the DTP output on the IN1608. To support

portable devices with analog video output, the switcher’s two universal

video inputs are primarily used for VGA laptops; however, these inputs

are easily configured for use with many other analog formats. The

advanced scaling engine converts all incoming digital and analog

video signals to the standardized resolution. “The IN1608 switcher

was selected because it could successfully handle the wide variety of

In the larger lecture halls, dual projection systems are installed, giving maximum flexibility while enhancing the viewing experience. KEDGE BUSINESS SCHOOL

resolutions available on newer laptops as well as reliably support the

legacy sources,” says Corthondo.

AudioThe lecture halls required sound reinforcement for microphones

and support of audio from a variety of recorded content. Also vital

to KEDGE, the AV system had to have the capability to support at

least five microphones, simultaneously. To enable exceptional sound,

all 11  lecture hall designs include the Extron DMP 128 digital matrix

processor. Each processor provides various audio tasks and signal

routing within the room, including support of wired and wireless

microphone feeds, audio conferencing with acoustic echo cancellation

— AEC, and distribution to amplifiers feeding overhead speakers.

According to the integrator, technologies built into the DMP 128

processor, such as Extron ProDSP™ 32/64‑bit floating point signal

processing, automixing with multiple mic groups to handle the large

number of live microphones, and eight channels of AEC for effective

remote conversations between multiple locations, made selection of

the DMP 128 an easy choice.

ControlExtron MediaLink controllers enable system power On/Off, input

selection, and volume adjustment within the lecture halls, and provide

control of local and connected sources as well as the projection

system within each classroom. Room size was used to determine

which MediaLink controller, either the MLC 226 IP or MLC 104 IP Plus,

best suited the primary function of the space. In lecture halls, each

MediaLink controller is connected to the network via Ethernet, while

RS‑232 ports are utilized to operate the IN1608 and provide display

control over the twisted pair cable to projector locations. Downloading

the Extron Control app provided an additional point of control from an

iPad. “When monitoring and controlling a MediaLink within an iPad,

the response is immediate and there is no delay, even in the most

spacious rooms,” says Renelleau.

KEDGE selected these MediaLink models for the proven reliability

and flexibility of the controllers, which are already in use in other

campus buildings. Additionally, the simple‑to‑use button functionality

provided familiarity to instructors holding classes in the new building.

Renelleau stated that the staff members appreciated the system on/off

capability and being able to easily switch between digital and analog

sources.

XTP System for Centralized ControlThe Extron XTP System links the lecture halls to support overflow

situations as well as video conferencing between rooms and

with remote sites. At the heart of the building’s AV system is the

XTP CrossPoint 3200 matrix switcher. The modular 32x32 matrix

switcher is populated with a combination of input and output boards

to support local and remote endpoints. Each lecture hall installation

includes an XTP HDMI transmitter and receiver to enable content

sharing between all locations, including the Control Room for centralized

monitoring and control. In addition, the design took advantage of

XTP‑enabled Ethernet extension to connect all IN1608 switchers for

resource management and Help Desk applications. Use of the XTP

Ethernet pass‑through port on each extender reduced the number of

independent network drops required within the halls. XTP transmitters

and receivers are powered remotely by the XTP CrossPoint® matrix

switcher, which further streamlined installation.

The five largest halls are equipped with two or three HD‑SDI PTZ

cameras to support the building’s video conferencing system. The

XTP System is used to share the VC codec between halls. Extron

DSC 3G‑HD A scalers perform 3G‑SDI to HDMI signal conversion

to tie the 12 PTZ cameras into the AV system. XTP HDMI input and

output boards are used for connectivity within the Control Room for

displays, multi‑image processors, streaming devices, and the resident

VC codec.

Extron’s GlobalViewer Enterprise provides centralized control of the

building’s AV applications and XTP System. Already used in other

campus buildings, this server‑based AV resource management

software allowed a system operator to monitor and control AV routing

and presentation from the Control Room using a single Extron

TLP 1000TV. This design also enabled enterprise‑wide scheduling and

help‑desk functionality to assist instructors new to the campus.

Successful OutcomeFrom equipment installation to system commissioning, the AV project

was completed within a two‑week semester break. Spaces within the

new facility are used regularly to support KEDGE’s 31 MBA programs.

According to Corthondo of Triaxe, the administration at this triple‑

accredited business school is quite pleased with the high quality

and dependability of their AV systems, especially the signal switching

speeds within the lecture halls. “We are proud of what has been

accomplished at the Bordeaux campus, and in such a short time,”

says Eric Renelleau of KEDGE. “Extron’s XTP System and IN1608

switchers provided all that we wanted in our new lecture building.”

Extron MediaLink controllers provide presentation control within classrooms as well as lecture halls.
