NOTE: The PT-76a and PT-38a were desig n ed for instal l ation on flat surfaces ONLY!
The PT-76 and PT-38 may NOT be pole mounted. Only the PT-30 is designed and
approved for pole mounting. One Systems offers the Pole Mount System-3 and the Pole
Mount System Ex-3 as well as the PT-30 for pole mo unti ng appl i cations. (See more
information in the PT-30 section below regarding pole mounting)

NO OTHER LOUDSPEAKERS SHOULD BE S UBSTITUTED!

The following actions MUST be performed PRIOR to beginning the installation of the
PT-76a, PT-38a, PT-30 or PT-10:

1. This installation guide must be completely read and understood

2. The instruction manual “Rigging and Suspension of ONE SYSTEMS
Products” must be read and understood. (This instruction manual is

available along with other technical papers at www.onesystems.com under
the “Documentation” tab

3. The structure of the mating surface MUST be capable of supporting the
combined weight of the pan and tilt bracket, the loudspeaker and all
associated rigging; and must satisfy the required safety factors specified by
local and national codes, as well as safe rigging practices.

The PT-76a weighs 10.5kg (23.1 lbs). The Pt-38a weights 4.16kg (9.2 lbs).

The PT-30 weighs 4.16kg (9.2 lbs). The PT-10 weighs 0.274kg (0.6 lbs)

4. The PT-76a, PT-38a, PT-30 and PT-10 pan and tilt brackets should be
installed only by someone experienced in the overhead suspension o f
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 pole structures.

5. The PT-76a and PT-38a are available in both 304 grade and 316 (Marine)

grade stainless steel. If the Marine grade version (316 stainless steel) is
being used then all associated rigging must also be 316 grade stainless
steel. If the PT-30 Marine grade product is being used please note that 316
grade Band-It straps are required.

NOTE: Caution should be exercised when connecting One Systems Marine grade products

and Marine grade rigging to other metallic, non 316 grade stainless steel surfaces (dissimilar
metals). The potential for galvanic corrosion is high in marine environments where the One
Systems Marine grade enclosures and rigging are specified or required. Compatible metals and
appropriate anode to cathode area ratios must be maintained. A structural engineer with
galvanic corrosion experience should be consulted prior to installation of marine grade products,
or ANY One Systems products in marine environments.

CAUTION: All structures outdoors are subjected to wind forces. These forces must be
considered when suspending any product outdoors. It is necessary to know the
“Effective Projected Area” (EPA) of the loudspeaker prior to installation of the
loudspeaker and the PT-76a, PT-38a, PT-30 or PT-10. See Appendix 1 of this
installation manual for effective projected areas for each enclosure rated for use with
the PT-76a, PT-38a, PT-30 and PT-10.

IMPORTANT NOTE: All products in direct weather installations can be subjected to high wind
speeds. For wind speed exposure over 74 miles per hour (119.1 kilometers per hour, 64.3
knots) the loudspeaker enclosure, bracket, banding, and link assembly or safety must be
inspected for signs of damage or fatigue!

INSTALLATION

NOTE: See separate instructions below for the PT-10 and PT-30

The PT-76a and PT-38a consist of three parts: the wall bracket, the loudspeaker
bracket, and the Link. Th e PT-76a wall bracket and loudspeaker bracket are shown in
Figure 1. Figure 1a shows the wall bracket portion of the PT-76a. The PT-76a bracket
allows the loudspeaker to be oriented from a 0 degree down tilt to a maximum down tilt
of 35 degrees in 5 degrees increments. The PT-38a allows a down tilt of 40 degrees in
8 degree increments.

Figure 2

Prior to mounting the wall bracket to the wall the speaker mount section should be
removed. See Figures 2a and 2b.

NOTE: The M10 bolts associated with the “pan” axis should be left in place, as shown in
both Figures 2a and 2b.

The wall bracket section should now be mounted to the wall surface. The PT-76a has
12 mounting holes and the PT-38a has 8 mounti ng holes for allowing fasteners to join
the bracket and loudspeaker assembly to the mating surface.

IT IS NECESSARY TO USE ALL MOUNTING HOLES TO INSURE A SAFE AND
SECURE MATE TO THE ASSOCIATED SURFACE! (12 for the PT-76a and 8 for the
PT-38a)

All fasteners associated with the mounting of the Pan and Tilt bracket and loudspeaker
assembly to the mating surface are the responsibility of others. The design and
structural capacity of mating surfaces (such as walls) vary greatly and specific fasteners
are designed for use with specific mating surfaces. One Systems 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 spe ci fic 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 PT BRACKET, THE LOUDSPEAKER AND ALL SUSPEN SION
HARDWARE, AS WELL AS PROVIDING THE PROPER SAFETY FACTORS. DO NOT
ATTEMPT TO SUSPEND THE BRACKET AND LOUDSPEAKER UNTIL THE
STRUCTURAL CHARACTERISTICS O F THE MATING SURFACE ARE
UNDERSTOOD. DO NOT INSTALL THE PT BRACKET AND LOUDSPEAKER IF THE
MATING SURFACE IS NOT CAPABLE OF SUPPORTING THE ENTIRE ASSEMBLY
WEIGHT, AS WELL AS PROVIDING THE REQUIRED SAFETY FACTORS!

After the PT wall section of the bracket is securely mounted to the m at ing surface, the
loudspeaker section should be mounted to the loudspeaker using the fasteners supplied.
(DO NOT SUBSTITUTE FASTENE RS) The loudspeaker mount section of each bracket
is shown in figures 2a and 2b. IMPOR TAN T, see the note below regarding the supplied

gasket. This note applies to the PT-76a bracket ONLY!
NOTE: There is a silicone rubber gasket supplied with the PT-76a. This gasket is used

when the 112IM, 212CIM, 212IM, 312CIM or 115TW is mounted using the PT-76a.
(This gasket is NOT REQUIRED when mounting the CFA or CFA-2 enclosures.)
Remove the pressure sensitive adhesive covering and attach the gasket to the
mounting surface of the PT-76a bracket where it joins the loudspeaker as shown below.

The PT-76a mounts to the rear of ALL IM series enclosures, except for the 108IM and

208CIM, using the 140mm x 90mm M10 locations as shown in figure 2c. The PT-38a
mounts to the top or bottom or top of the 108IM or 208CIM as shown in figure 2c using
the M8 locations. The mounting locations are highlighted in red. (SEE IMPORTANT

NOTE REGARDING THE M10 FLAT WASHERS AND T HE PT-76a BELOW)

DO NOT SUBSTITUTE MOUNTING LOCATIO NS!

NOTE: There are 8 each hex head M10 bolts supplied in the mounting kit of the PT-76a.
When mounting the 115TW (wood) enclosures to the PT-76 use 4 each of the 45mm
(longer) M10 bolts. The 4 shorter M10 bolts are used for the IM series injection molded
enclosures and the CFA enclosures.

NOTE: There are M10 flat washers in the PT-76a kit. DO NOT USE THESE WASHERS
FOR MOUNTING THE 112IM, 212CIM, 212IM ,or 312CIM! The M10 flat washers are
for use with the CFA and CFA-2 ONLY! (See the image below, DO NOT use flat
washers under the M10 bolts used to mount the 112IM, 212CIM, 212IM, or 312CIM.)

The image above shows the M10 bolts WITHOUT WASHERS used to mount either a
112IM, 212CIM, 212IM, or 312CIM. The M10 flat washers are used ONLY with the CFA
or CFA-2 enclosure!

Additionally, there are forged shoulder eyebolts supplied in the PT kits, 4 each M10
eyebolts for the PT-76a and 3 each M8 eyebolt for the PT-38a. One of these eyebolts
must be installed in the top, rear portion of the enclosure. When installing the PT-76a,
use the longer of the two M10 eyebolts for wood enclosures and the shorter of the two
M10 eyebolts for the IM series enclosures. Make sure that the eyebolt is seated on the
surface of the enclosure.

The loudspeaker and loudspeaker section of the br ac ket m ay 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.

The M10 tilt pivot bolt should be inserted first and secured but not completely tightened
using the nylon insert M10 nuts supplied. The tilt pivot bolt is shown below in Figure 2d.
Then the M10 tilt aiming bolt should be inserted and nylon insert nuts applied. Then the
tilt axis bolts should be tightened.

CAUTION: DO NOT REMOVE THE PAN PIVOT BOLT
Next the pan angle may be adjusted by removing the M10 pan aiming bolt, but NOT the

pan pivot bolt, and setting the desired pan angle and then re inserting the M10 bolt.
Once both the tilt and pan angles are set, make sure that all bolts are tight and secure.
