Introduction
The Apogee ALA-C1 Acoustic Line Array Loudspeaker is a high-fidelity
70V/8-ohm, passive, 2-way xed column, all-weather loudspeaker. It provides
superb speech enhancement and music reproduction for small- to medium-sized
venues, such as school and civic auditoriums, community theaters, lecture halls,
and houses of worship. This system’s design offers broad horizontal dispersion
(140-degrees) and focused vertical dispersion (25-degrees), which is ideal for
uniform side-to-side coverage, while minimizing ceiling and oor reections that
could degrade intelligibility. Mounting is via an included bracket that allows for
vertical down tilt of 0-10-degrees.
Package Contents
The ALA-C1 System Package contents include:
• One (1) ALA-C1 Acoustic Line Array Loudspeaker User Manual
• One (1) ALA-C1 Acoustic Line Array Loudspeaker with
a pre-installed sliding mounting bracket
• One (1) ALA-C1 Wall Mount Kit

Mounting Instructions
Mounting is via an included wall-mount plate set that allows for vertical down
tilt of 0-, 5-, or 10-degrees. The ALA-C1 Loudspeaker has a pre-installed sliding
mounting bracket. The mounting bracket slides freely along a built-in bracket
channel on the rear of the speaker enclosure.
IMPORTANT SAFETY INSTRUCTIONS
Always follow these safety precautions when using or installing
the ALA-C1 Loudspeaker and accessories:
• Read and keep these instructions.
• Heed all warnings.
• Follow all instructions, particularly those pertaining to rigging,
mounting, hanging, and electrical connections.
• Only use accessories that are specied and approved by Bogen.

1. Attach the Wall-Mount Plate A to the desired location on the wall using the
proper fasteners.
NOTE: Wall-Mount fasteners are NOT INCLUDED as mounting requirements vary
depending on the wall structure or surface.
Screws should be used in each of the four holes on the Wall-Mount Plate A
as shown in Figure 1 to ensure that the plate supports the entire weight of
the loudspeaker. The screws and the wall material/supporting structure
must support the entire speaker weight. Failure to do so could lead to an
unsafe mounting.
2. Slide the mounting bracket to the desired position on the back of the speaker.
The mounting bracket can be slid freely along the back of the speaker
enclosure. To prevent top-heavy installation, we recommend installing the
mounting bracket as high on the speaker as possible while still allowing you
to achieve the desired install angle.
NOTE: For 0- or 5-degree tilts, use the full range of the speaker enclosure. For a
10-degree tilt, we recommend sliding the bracket down to the built-in stop.
3. Use the four M4.7 self drilling screws and four M5 lock washers to secure
the mounting bracket to the speaker. Tighten each screw to 24-26 in-lbs.

4. Select the desired tilt knuckle.
NOTE: Two different tilt knuckles are included to provide the vertical focus angle
or optimal coverage. Use the tilt knuckle with sticker A for a 0-degree or a 10-degree
angle. Use the tilt knuckle with sticker B for a 5-degree angle. (See Figure 3.)
5. Bolt the selected tilt knuckle to the Wall-Mount Plate B using the three M6 x
14mm screws and lock washers included in the mounting kit. Tighten each
screw to 40-45 in-lbs. (See Figure 4.)
NOTE: Verify that the screws are securely tightened to the torque specs provided.
Failure to do so may result in an unsafe installation.

6. Attach the two knuckle pieces together.
To have 0-degree installation, make
sure the Wall-Mount Plate B is parallel
to the speaker enclosure. Rotate the
top tilt knuckle one step clockwise to
obtain a 10-degree tilt. (See Figure 5.)
7. Secure both knuckle pieces using one M8 hex head screw and M8 lock
washer. Tighten the screw to 95-105 in-lbs.
WARNING
All fasteners must be securely tightened to keep the speaker in
position and ensure it is securely mounted. Failure to follow this
instruction may result in property damage, injury, death, and/or
legal liability to you and your company.

8. Arrange the speaker so that Wall-Mount Plate B slides over the top of Wall-
Mount Plate A. The folded edges on the top side of the plates should line up.
9. Align the screw holes on the sides of Wall-Mount Plate A with those on Wall-Mount
Plate B and secure them using two M4 sheet metal screws with lock washers.
Tighten each screw to 18 in-lbs. (See Figure 7.)

Rigging Installation
A safety cable (supplied) must be used whenever an ALA-C1 is mounted using
the supplied mounting bracket. The safety cable must be secured to a suitable
load-bearing point (not supplied) on the wall or ceiling. After nal positioning of
the loudspeaker, make sure that the cable is taut to minimize shock load in the
event of bracket failure.
WARNING
The loudspeaker described in this manual is designed and
intended to be mounted using a variety of rigging hardware,
means, and methods. Severe injury and/or loss of life may occur
if the speaker is improperly installed. Only trained and qualied
personnel should install the ALA-C1 loudspeaker. We recom-
mend that a licensed and certified professional structural
engineer approve the mounting plan.
WARNING
All rigging ttings must be fully tightened and secured. Any
missing fasteners will compromise the structural integrity of the
enclosure and constitute a safety hazard. Do not suspend this
loudspeaker unless all fasteners are securely in place.
WARNING
The working load should never be exceeded. Failure to follow
this instruction may result in property damage, injury, death,
and/or legal liability to you and your company.

1. Secure the xed loop of the safety cable to the wall using the appropriate
user-provided bolt or hook (See Figure 8.)
2. Thread the cable through the eyebolt that is pre-installed on rear of the speaker.
3. Adjust the free cable as needed to remove slack and then secure in place using
the cable clamps that are provided.
