PTB-8NP with OPA-8NP enclosure
The On Point Audio PTB-8NP is an easy to install and flexible system designed to allow
the OPA-8NP loudspeaker enclosure to be mounted on a ceiling or other structural flat
overhead surfaces. The only products approved for use with the PTB-8NP is the OPA8NP enclosure. NO other products may be substituted!
WARNING: The PTB-8NP is NOT designed for wall mount. The PTB-8NP is designed
for ceiling mount ONLY!

NOTE:The OPA-8NP enclosure and PTB-8NP are for INDOOR use only! DO NOT
USE IN OUTDOOR ENVIRONMENTS!
The following actions MUST be performed PRIOR to beginning the installation of the
PTB-8NP and OPA-8NP:
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 PTB-8NP bracket, the OPA-8NP 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 PTB-8NP
weighs 2.3kg (5.1 lbs). The OPA-8NP enclosure weighs 6.8kg (15 lbs).
4. The PTB-8NP 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.
5. The PTB-8NP is designed for ceiling mount ONLY! DO NOT WALL
MOUNT!
CAUTION: The PTB-8NP bracket and OPA-8NP enclosures are designed for INDOOR
use and installation ONLY! DO NOT INSTALL IN OUTDOOR ENVIRONMENTS!

INSTALLATION
The PTB-8NP consists of two parts: the ceiling bracket and the loudspeaker bracket.
The ceiling bracket and loudspeaker bracket are shown below in Figure 1.

Ceiling Bracket Loudspeaker Bracket
Figure 1
The ceiling bracket and loudspeaker bracket are joined together by a hex head M10 bolt
and nylon insert M10 nut assembly. DO NOT remove this M10 bolt and nut assembly.
The combination of the ceiling bracket and loudspeaker bracket should stay assembled
during mounting to the ceiling.
The ceiling bracket is mounted to a ceiling surface using the four (4) holes shown in red
in Figure 2 (below).

Fig ur e 2
Figure 2 (above) shows the four (4) mounting locations to join the ceiling bracket to a
ceiling surface. These four mounting locations are designed to allow M10 diameter
hardware. The ceiling bracket section should now be mounted to the ceiling surface.
IT IS NECESSARY TO USE ALL FOUR (4) MOUNTING HOLES TO ENSURE A SAFE
AND SECURE MATE TO THE ASSOCIATED SURFACE!
All fasteners associated with the mounting of the PTB-8NP ceiling bracket to the mating
surface are the responsibility of others. The design and structural capacity of mating
surfaces (ceilings) 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 ap p r opr i ate c hoic e o f faste ner s for those
specific surfaces.
The ceiling 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 PTB-8NP BRACKET AND THE OPA-8NP LOUDSPEAKER AND ALL
SUSPENSION HARDWARE, AS WELL AS PROVIDING THE PROPER SAFETY
FACTORS. DO NOT ATTEMPT TO SUSPEND T HE BRACKET AND LOUDSPEAKER
UNTIL THE STRUCTURAL CHARACTERISTICS OF THE MATING SURFACE ARE
UNDERSTOOD. DO NOT INSTALL THE PTB-8NP BRACKET AND OPA-8NP

LOUDSPEAKER IF THE MATING SURFACE IS NOT CAPABLE OF SUPPORTING
THE ENTIRE ASSEMBLY WEIGHT, AS WELL AS PROVIDING THE REQUIRED
SAFETY FACTORS!
After the PTB-8NP ceiling section of the bracket is securely mounted to the ceiling, the
OPA-8NP loudspeaker enclosure should be attached to the loudspeaker bracket using
the fasteners supplie d. (DO NOT SUBSTITUTE FASTENERS)
NOTE: There are 2 each M8 bolts supplied in the mounting kit of the PTB-8NP.
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 PTB-8NP bracket. Safety harnesses should always be worn
when working from an elevated platform.
Insure that the two rubber spacers are installed between the side walls of the enclosure
and the loudspeaker bracket section of the PTB-8NP as shown below in Figure 3.

Figure 3
Install the two large rubber spacers (100mm diameter) on each side of the enclosure
between the enclosure and the loudspeaker bracket section as shown.
Then install the M8x40mm bolts (one on each side of the loudspeaker bracket) making
sure to use both the supplied M8 flat washers AND lock washers. BOTH THE FLAT WASHERS AND LOCK WASHERS MUST BE US ED! Figure 4 (Below) shows is an
image of the PRB-8NP showing the rubber spacer, loudspeaker bracket, flat washer,
6
lock washer and M8 bolt. Only the right side is shown below in Figure 4, but BOTH
sides must utilize the 100mm diameter rubber washer!
Figure 4
Figure 5 is a close up of the right side of the assembly shown in Figure 4. (Right side shown for
clarity, left side is iden tical). The washer, lock washer, rubber washer and M8 bolt must be used
on BOTH sides of the loudspeaker bracket to fix the OPA-8NP to the PTB-8NP pan and tilt
bracket!
Set the desired tilt angle of the OPA-8NP loudspeaker in the loudspeaker bracket and
then securely tighten the two (2) M8 bolts against the sides of the loudspeaker bracket.
Now the pan angle may be set. The PTB-8NP allows pan angle aiming in 10 degree
increments thru a full 360 degree circle. Once the desired pan angle is set the M10 bolt
and nylon insert nut that secure the ceiling bracket to the loudspeaker bracket may be
tightened.

Tighten the M10 hex head bolt and nylon insert nut once the pan angle has been set.
NOTE: Secondary safety cables are STRONGLY recommended and should be secured
to a structural point NOT associated with the PTB-8NP bracket or louds peaker!
