Basic Setup

The basic setup includes:

  • instructor station
  • 2500 (or higher) lumen projector
  • ceiling speakers
  • media switcher
  • amplifier
  • computer with monitor
  • Extron MLC-104-IP or MLC-226 controller
  • 2 USB connectors on the desktop for connection to the PC

For a laptop, there is power, network connectivity, and a pull-through VGA cable with audio. To see the various configurations, click the appropriate link in the left navigation bar.

Instructor Station


This sit/stand station comes with an articulating keyboard, and the desktop podium has a flip-and-store monitor. The keyboard can be used in a seated or standing position.


The podium comes with a flip-and-store monitor and all the standard features of the desktop lectern. It also includes some extra storage on one side of the podium.

The science labs at Dale Mabry have an equipment rack on one side of the built-in desk and a document camera on the opposite side. The monitor is on an articulating arm that is attached to the desk and can be moved out of the way when not in use.

Half-size Podium

The half-size podium is designed for spaces that are too small for a standard 42" wide podium. It measures 24" wide and comes with a document camera on a side pull-out shelf and a monitor attached to an articulating arm in front.


Standard Projector

The standard projector is 2500 lumens, which can illuminate a screen projection with half or all room lights on.

Alternate Projector

Due to design, size, or lighting conditions, some rooms require a projector that exceeds the 2500 lumen requirement.



Tower computers were initially installed in all classrooms.


After the first year, all computers were rack mounted for easier access and repair.

Document Camera

Document Camera

Connected directly to the video/data projector, the document camera is used for viewing printed materials, 3D objects, photos, slides, negative and positive film, as well as x-rays.

Amplifier, DVD/VCR, and Switcher

The amplifier is for larger rooms with more than 4 speakers. The DVD/VCR is controlled by the MLC controller panel--no remote is necessary. The media switcher controls the output to the projector and the speakers.

NOTE: For information on volume control, click on the 'Volume' link.


MLC-226 IP Plus

The newest controller comes with DVD/VCR controls and picture mute. Picture mute lets instructors temporarily block out screen projections.

MLC-104 IP DV+

The first controller had a different layout and fewer controls than the MLC-226.


In general, the volume control knob on the MLC 226 (or 104) is all that is needed to adjust the room volume, provided the switcher and the amplifier are preset.

If the DVD/VCR output is not loud enough, even though the MLC volume is at the red level, then the volume control on the switcher can be adjusted, followed by the volume control on the amplifier.

The computer also comes with two other volume controls. One is the speaker icon in the notification bar (bottom right). Double click on the icon, and make sure the volume is not muted and that the volume is appropriately adjusted. Another is the volume control that comes with any media player such as Windows Media, QuickTime, VLC, WinAmp, etc. Be sure the player's volume is not muted and appropriately adjusted.

If the above steps do not work, then the campus A/V Tech should be contacted.

It is recommended that instructors check volume settings before the start of class.
