OPA-PTB with OPALine enclosure
The On Point Audio OPA-PTB is an easy to install and flexible system designed to allow
the OPALine loudspeaker enclosure to be mounted to wall or other structural flat
surfaces. The only products approved for use with the OPA-PTB are the OPALine
enclosure and the OPA-12. NO other products may be substituted!

NOTE: The OPA-PTB was designed to be mounted on walls or other structural flat
surfaces ONLY! The OPALine enclosure and OPA-P T B are for INDOOR use only! DO
NOT USE IN OUTDOOR ENVIRONMENTS!
NO OTHER LOUDSPEAKERS SHOULD BE S UBSTITUTED!
The following actions MUST be performed PRIOR to beginning the install ati on of the
OPA-PTB and OPALine or OPA-12 enclosure:
1. This installation guide must be completely read and understood.
2. The instruc ti on man ual “Ri g g i ng and Suspension of On Point Audio
Products” must be read and understood. (This instruction manual is
available along with other technical papers at www.onpointaudio.com)
3. The structure of the mating surface MUST be capable of supporting the
combined weight of the OPA-PTB bracket, the OPALine or OPA-12
loudspeaker and all associated rigging. It must satisfy the required safety
factors specified by local and national codes, as well as safe rigging
practices. The OPA-PTB weighs 9.7k g (21.4 lbs). The OPALine enclosure
weighs 39kg (86 lbs). The OPA-12 enclosure weighs 33kg (66lbs)
4. The OPA-PTB pan and tilt bracket should be installed only by someone
experienced in the overhead suspension of items. They should be familiar
with applicable local/national codes governing the installation of these types
of products and those governing the attachment of these types of products
to specific structures.
CAUTION: The OPA-PTB bracket and OPALine and OPA-12 enclosures are designed
for INDOOR use and installation ONLY! DO NOT INSTALL IN OUTDOOR
ENVIRONMENTS!

Prior to mounting the wall bracket to the wall or appropriate flat surface, the loudspeaker
bracket section shoul d be removed. The loudspeaker bracket is removed by taking out
the two M10 bolts that hold the loudspeaker bracket to the wall bracket assembly. The
M10 bolts are shown in figure 1a below.

The wall bracket section should now be mounted to the wall surface. The OPA-PTB has
10 mounting holes for allowing fasteners to join the bracket and loudspeaker assembly
to the mating surface.
IT IS NECESSARY TO USE ALL MOUNTING HOLES TO ENSURE A SAFE AND
SECURE MATE TO THE ASSOCIATED SURFACE!
All fasteners associated with the mounting of the OPA-PTB bracket and loudspeaker
assembly to the mating surface are the responsibility of others. The design and
structural capacity of mating surfaces (suc h as walls) vary greatly and specific fasteners
are designed for use with specific mating surfaces. On Point Audio does not
recommend any mating fasteners and strongly urges the installer to consult with one
experienced in suspension of products from the specific mating surfaces and the
appropriate choice of fasteners for those specific surfaces.
The wall bracket section should be secured firmly to the mating surface using the
appropriate fastening system. The fastening system should be determined by the
structure of the mating sur face.
IT IS CRITICAL THAT THE MATING SURFACE BE CAPABLE OF SUPPORTING THE
LOAD OF THE OPA-PTB BRACKET, THE OPALINE OR OPA-12 LOUDSPEAKER
AND ALL SUSPENSION HARDWARE, AS WELL AS PROVIDING THE PROPER
SAFETY FACTORS. DO NOT ATTEMPT TO SUSPEND THE BRACKET AND
LOUDSPEAKER UNTIL THE STRUCTURAL CHARACTERISTICS OF THE MATING
SURFACE ARE UNDERSTOOD. DO NOT INSTALL THE OPA-PTB BRACKET AND
OPALINE OR OPA-12 LOUDSPEAKER IF THE MATING SURFACE IS NOT CAPABLE
OF SUPPORTING THE ENTIRE ASSEMBLY WEIGHT, AS WELL AS PROVIDING
THE REQUIRED SAFETY FACTORS!
After the OPA-PTB wall section of the bracket is securely mounted to the mating
surface, the loudspeaker section should be mounted to the OPALine or OPA-12
loudspeaker using the fas te ner s suppl i ed . (DO NOT SUBSTITUTE FASTENERS) The
loudspeaker mount section of the bracket is shown in figures 3a and 3b.

NOTE: There are 4 each hex head M10 bolts supplied in the mounting kit of the OPAPTB. When mounting the OPALine or OPA-12 enclosure to the OPA-PTB use 4 each of
the 45 mm M10 bolts. Additionally, there is a forged shoulder eyebolt supplied in the
OPA-PTB kit. This eyebolt must be installed in the top, rear center portion of the
OPALine or OPA-12 enclosure. Make sure that the eyebolt is seated on the surface of
the enclosure. The eyebolt is shown below in figure 4.

The loudspeaker and loudspeaker section of the bracket may now be joined to the wall
section and the required pan and tilt angles selected. This is a two person job and
extreme care should be exercised to avoid serious injury.
USE EXTREME CAUTION! The loudspeaker is heavy and it is likely that the desired
mounting location is high in the air. This process should never be attempted by a single
person.
TWO OR MORE PEOPLE ARE REQUIRED TO MOUNT THE LOUDSPEAKER
ENCLOSURE TO THE OPA-PTB bracket. Safety harnesses should always be worn
when working from an elevated platform.
The OPALine or OPA-12 enclosure, with loudspeaker bracket attached, should be
mounted to the wall section of the OPA-PTB.
The M10 tilt pivot bolt should be inserted first and secured, but not completely tightened
using the nylon insert M10 nuts that are supplied. The tilt pivot bolt is shown below in
Figure 5. At this point the M10 tilt aiming bolt (Figure 5a) should be inserted into the
desired angle and the nylon insert nuts applied. Then the tilt axis bolts should be
partially tightened. (see below for FULL tightening recommendations after the aiming
bolt has been set to the proper angle).
Figure 5 showing the tilt pivot bolt. This must be inserted first.
Figure 5a below shows the tilt aiming bolt. This can only be inserted AFTER the tile
pivot bolt is installed and partially tightened!

Now the pan aiming bolt can be adjusted if needed. NOTE: The pa n pivot bolt should
NOT be removed.
The pan angle can be adjusted by removing the pan angle aiming bolt as shown below
in Figure 5b.

!Once both the tilt and pan angles are set, make sure that all aiming and piv ot bolts for
both the pan and tilt axis are tight and secure!

INSTALLING THE LINK
Figure 6 is a representation of the Link assembly. This assembly MUST be used
whenever the OPA-PTB and the OPALine or OPA-12 enclosure are being used
together. Each pan and tilt bracket is supplied with a link assembly.
Figure 6
UNDER NO CIRCUMSTANCES SHOULD THE DOWNWARD TILT OF THE
LOUDSPEAKER EXCEED 35 DEGREES FROM VERTICAL FOR THE OPA-PTB and
OPALine enclosure.
SECTION 5 LINK ASSEMBLY
Now the Link must be installed.
INSTALLING the OPA-PTB Bracket WITHOUT THE LINK IS NOT ALLOWED!
The Link (see figure 6) consists of quick links, a turnbuckle, and several links of steel
chain. The use of the chain pieces and quick links with the turnbuckle is based on the tilt
angle of the enclosure. The turnbuckle should always be used.
DO NOT SUBSTITUTE ANY PART OF THIS LINK ASSEMBLY!
The Link should be tightened by rotating the turnbuckle until there is
tension on the Link assembly. Do not over tighten. The purpose of the Link
is to provide support for the main OPA-PTB tilting bracket at the bottom of
the assembly. ONLY ROTATE THE TURNBUCKLE UNTIL THERE IS
VERY SLIGHT TENSION. DO NOT TIGHTEN B E YOND THIS P OI NT!
The back plate section of the OPA-P TB has eyebolts attached to it. There are two (2)
eyebolts on the back plate section of the OPA-PTB.
Make certain to use the appropriate combination of Link parts to ensure proper
connection between the OPA-PTB bracket assembly and the OPALine or OPA-12
enclosure. The required combination of link parts is determined by the down tilt angle of
the enclosure.

The assembly may be configured with any combination of turnbuckle, chain link
sections and quick link in order to achieve the proper tension on the system, but the
turnbuckle must always be used. The selection of the correct eyebolt will be determined
by the down tilt angle of the enclosure.
Warning: If the turnbuckle assembly is turned and the loudspeaker enclosure angle
begins to change, (if the down tilt angle begins to move toward 0 degrees vertical) then
the turnbuckle has been OVER TIGHTENED. Turn the turnbuckle until the down tilt
angle is set by the M10 thru bolt on the pole bracket, but there still should be slight
tension on the turnbuckle.
Figure 7 is a close up view of the Link assembly. Certain down tilt angles may require a
link to be “dropped” from the chain as shown below. The lower quick link is positioned in
various chain segments based on the desired degree of down tilt. The turnbuckle should
be adjusted, as described in this section.
In any position, the turnbuckle must be adjusted to allow the proper amount of tension
on the Link. The Link should never pull the loudspeaker up towards vertical. The Link
may be configured with or without the chain section and quick link, depending on the
down tilt angle of the enclosure.
Figure 7
Secondary safety cables are STRONGLY recommended and should be
secured to a structural point NOT associated with the OPA-PTB brac ket or
loudspeaker enclosure. The Link assembly is NOT a secondary safety
cable.
