CONSTRUCTION DIAGRAM
Fig. 1 illustrates the components and assembly points. It shows the two main bracket parts (speaker side and ceiling/wall side) and the hardware used. Key components labeled include: "Speaker cord hole", "Holes for bolts to fix bracket onto ceiling or wall", "Snap pin", "Lock screw", "Rotation lock screws", and "Joint bolt" with its associated washers. It also indicates the supplied wrenches.
Supplied accessory: 2 hexagonal wrenches (of small and large sizes) and 4 M5x12 screws.
Note on Lock Screw: Never loosen the lock screw which is to prevent the unit from coming apart. It can be identified by its head as shown below: [lock-screw-symbol].
Required External Hardware:
- Prepare M5 bolts (4 pcs.), M5 hexagonal nuts (8 pcs.) and Ø5 plain washers (8 pcs.). These are necessary to fix the ceiling/wall side bracket.
- Prepare M5 bolts (2 pcs.) and M5 hexagonal nuts (4 pcs.) to fix the speaker side bracket to the speaker. (These are not necessary when using a YAMAHA speaker system which this product is intended for.)
INSTALLATION PROCEDURE
- Separate the ceiling/wall side bracket and the speaker side bracket.
Fig. 2 shows the separation process. With the snap pin removed first, remove the joint bolt (with a plain washer and spring washer) by using the supplied hexagonal wrench (large).
- Securely attach the speaker side bracket to the speaker as shown below.
Fig. 3 illustrates this step. When attaching the bracket to the speaker system of wooden enclosure, remove the woofer first and fix the bracket with 2 M5 bolts and 4 M5 hexagonal nuts (double-nut installation). Add a sub board for security if possible.
Note: When using this bracket for the YAMAHA speaker system for which it is intended, fix the bracket with the supplied 2 M5x12 screws securely.
Diagram description for Fig. 3: Shows the speaker side bracket being attached to the back of a speaker, detailing the use of M5 bolts, M5 hexagonal nuts, and optional sub board. It depicts the "Top panel of speaker" and "Sub board", and mentions "double-nut installation".
- Attach the ceiling/wall side bracket to a sufficiently strong wall or ceiling.
Fig. 4 provides details. For installation, use 2 M5 hexagonal nuts and 2 Ø5 plain washers for each of 4 M5 bolts as shown above (double-nut installation).
Note: To get the speaker cord from behind the wall or ceiling, make a hole through it at a position that aligns with the speaker cord hole in the bracket. Draw the speaker cord out of the wall or ceiling to the speaker without slack by using clamps. It is easy to clamp and unclamp the speaker cord.
Diagram description for Fig. 4: Shows the ceiling/wall side bracket being mounted to a surface (labeled "Ceiling or wall"). It details the use of M5 bolts, Ø5 plain washers, and M5 hexagonal nuts for securing the bracket. It also shows the "Speaker cord hole" on the bracket.
- Connect the ceiling/wall side bracket and speaker side bracket.
Fig. 5 shows this connection. Align the two joint parts of both brackets so that their serrations fit each other properly and fasten them with the joint bolt. For this installation, make sure not to leave out a spring washer, plain washer, and snap pin.
Diagram description for Fig. 5: Shows the speaker side bracket and ceiling/wall side bracket being joined. It illustrates aligning serrated surfaces and securing them with the joint bolt, spring washer, plain washer, and snap pin.
SPEAKER ANGLE ADJUSTMENT
The bracket can be adjusted so that the speaker is set for the desired listening position.
Fig. 6 details the adjustment mechanism.
- Using Rotation Lock Screws: Loosen the 2 rotation lock screws (using the supplied hexagonal wrench (small)) to set the speaker to the desired angle, then retighten them securely. Do not attempt to move the speaker without loosening both rotation lock screws.
- Using Joint Bolt: Loosen the joint bolt (using the supplied hexagonal wrench (large)) by two or more turns. Set the speaker to the desired angle, and then retighten the joint bolt. Caution: Loosening this bolt too much can cause the lower bracket to come off. Do not loosen more than necessary for the angle adjustment.
The maximum adjustable angle is 360° for some movements and 220°/10° for others, depending on the pivot point.
