WALL MOUNTING PLATE

There are 4 holes in the round wall mounting plate for securing it to a wall. Please note that countersunk screws are required to secure the plate and ensure that their flat heads are flush with the plate (screws are not included in the packaging content). The wall mounting plate is equipped with a 4-pole terminal block, sliding contacts, and two openings for speaker cables.

TERMINAL BLOCK
4-pole terminal block with spring clamping for connecting a speaker cable with an up to 2.5 mm² cross-section and for sending the amplifier signal to another speaker connected in parallel. Please note the markings directly over the contacts for the correct polarity. Open the terminal contacts of the terminal block by sliding a small screwdriver with a flat head into the small opening above the respective contact. Now insert the stripped speaker cable into the terminal contact and pull the screwdriver out of the opening once again to close the terminal contact.
CENTRAL CABLE BUSHING
Central cable bushing for speaker cables installed in a wall. Carefully pull the cable coming from the wall through the 2mm drill hole present in the rubber sealing. The drill hole in the rubber seal is stretched as a result and therefore surrounds the cable.
When mounting outdoors: If the rubber sealing is torn when mounting, seal the tears and open points in the rubber sealing using silicone sealant.
SLIDING CONTACTS
When the speaker is correctly connected to the wall mounting plate, the speaker signal coming from the amplifier is transmitted via the sliding contacts to the speaker.
LOWER CABLE BUSHING
Lower cable bushing for speaker cables installed on a wall. In order to release the cable bushing, the sealing cap made of plastic must be removed prior to attaching the wall mounting plate to a wall.
When mounting outdoors: Seal open points between cable and cable bushing after installation using silicone sealant.

WALL MOUNTING
The speaker has a wall bracket with a practical lock mechanism. Thanks to the integrated connector panel, the speaker can also be used in visually demanding environments without visible cables. The 27° tilt and 45° swivel mechanism enable exact positioning for precise sound coverage.

Important safety information: Overhead mounting requires experience, including the calculation of the limits for the workload, the installation material used, and regular safety tests of all installation materials and speakers. If you are not qualified, do not try to perform the installation yourself, but use a professional company!

1 Prior to installing the speaker, remove the wall mounting plate from the wall bracket.
To do this, loosen the safety screw A in the dome-shaped union nut using the hex key included, turn the union nut counterclockwise from the wall bracket and pull the wall mounting plate B downwards from the wall bracket.

WAY PASSIVE INDOORb OUTDOOR LOUDSPEAKER - FIG 10

2 Firmly secure the wall mounting plate with the terminal block at the top using suitable screws on a wall sufficiently capable of supporting the load. For speaker cables laid under the plaster, the corresponding cable must be inserted through the central cable bushing prior to securing the wall mounting plate. Now connect the speaker cables to the corresponding contacts of the terminal block.

3 Slide the speaker with the wall bracket from above onto the wall mounting plate in such a way that the contacts on the speaker slide into the guide grooves of the sliding contacts of the wall mounting plate and the retaining hook engage into the corresponding recess.

4 Using the ball joint in the wall bracket, the speaker can be turned to the vertical or the horizontal position (turning in both directions by a maximum of 180°). Then tilt and swivel the speaker into the desired beam direction C. Now fix the speaker by screwing the dome-shaped union nut

D clockwise tightly onto the associated thread until the marking on the union nut matches either the marking on the retaining hook E or the marking on the wall mounting plate F to ensure that the safety screw can also engage into one of the two through-holes in the collet.
