CAUTION

To ensure correct equipment
placement and operation, this
installation procedure should be
performed by authorized
personnel only.

Preparing the Installation Site

Take the following steps to prepare the installation site:

1. Determine and obtain the electronics, MAAPs (Mini Architectural Adaptor
Plates), and cables required for this installation.

2. Turn off all equipment. Make sure the computer, Extender, and output
devices (projector, monitor, etc.) are all turned off and disconnected from the
power source.

3. Select an installation site that allows cable runs without interference. Allow
enough depth for both the floor box and the cables.

4. Install the floor box in accordance with the instructions Ackermann provided
with the floor box.

5. Route all cables required for the installation through the floor box and
terminate the cables with connectors if needed.

CAUTION

Exposed cable shields (braids or foil) are potential sources of short circuits.
To prevent short circuits, shields should be trimmed back or insulated with
heat shrink. Both braided and foil shields should be connected to an
equipment ground at the other end of the cable.

Identifying the Parts

The Extender AKM MAAP assembly, shown
at right, consists of the four metal pieces
(main enclosure, upper mounting plate,
lower mounting plate, and nut bar), blank
MAAP plates, an Extender line driver, and
the screws that hold it all together.

Installation and Cabling

The Extender must be cabled, optional MAAPs must be installed and cabled, and
both the Extender and MAAPs must be tested before attaching mounting plates to
the enclosure and mounting the assembly into the floor box.

1. Unpack the Extender AKM MAAP and any optional MAAPs. Save all the
screws—you will need them later.

• Each faceplate assembly comes with four #6-32 x 1/4" to 3/8" long

Phillips pan head screws.

• Each MAAP faceplate or module requires at least two socket-head cap

screws (#4-40 x 1/4") for securing the MAAP to a faceplate. Six of these
screws are included with the Extender AKM MAAP along with a small

#4 - 40

2. Route the cables up out of the Ackermann floor box and through the opening
in the upper mounting plate.

3. Connect audio output and power cables to the Extender’s direct insertion
captive screw connectors. See the illustrations below, and refer to the
Extender Series User’s Manual (part #68-552-01, available at www.extron.com) .

CAUTION

Use a 9 VDC to 18 VDC power supply only. Polarity is not important.
For best results and to reduce the risk of short circuits, trim just 0.2"
(5 mm) of the jacket from the wires. Do not tin the wires.

4. Loosely attach the upper mounting plate to the lower mounting plate and the
nut bar using the two provided Phillips pan head screws as shown below.

5. Set the Extender’s gain switch, which will be inaccessible after installation.
The gain switch is located at the rear of the Extender, between the two circuit

boards. Slide this switch to select the level of
