Acoustic Line Array Loudspeaker System
User Manual
Introduction
The Apogee ALA-C1 Acoustic Line Array Loudspeaker is a high-fidelity 70V/8-ohm, passive, 2-way fixed 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 floor reflections that could degrade intelligibility. Mounting is via an included bracket that allows for vertical down tilt of 0-10-degrees.

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 specified and approved by Bogen.
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.
-
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. -
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. -
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.
-
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.) -
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. -
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.) -
Secure both knuckle pieces using one M8 hex head screw and M8 lock washer. Tighten the screw to 95-105 in-lbs.
NOTE: Make sure all parts are assembled in the order shown in Figure 6.
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. -
Arrange the speaker so that Wall-Mount Plate B slides over the top of WallMount Plate A. The folded edges on the top side of the plates should line up.
-
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
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 qualified personnel should install the ALA-C1 loudspeaker. We
recommend that a licensed and certified professional structural engineer
approve the mounting plan.
WARNING
All rigging fittings 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.
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 final
positioning of the loudspeaker, make sure that the cable is taut to minimize
shock load in the event of bracket failure.
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.
- Secure the fixed loop of the safety cable to the wall using the appropriate user-provided bolt or hook (See Figure 8.)
- Thread the cable through the eyebolt that is pre-installed on rear of the speaker.
- Adjust the free cable as needed to remove slack and then secure in place using the cable clamps that are provided.
WARNING
Cable clamps must be securely tightened. Failure to do so may result in
property damage, injury, death, and/or legal liability to you and your
company.
