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.

One Systems, Inc. 6204 Gardendale Dr., Nashville, TN 37215 www.onesystems.com

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!

UNDER NO CIRCUMSTANCES SHOULD THE LOUDSPEAKER DOWNWARD TILT
EXCEED 35 DEGREES FROM VERTICAL FOR THE PT-76a. (MAXIMUM 40
DEGREES FOR THE PT-38a)

SECTION 5 LINK ASSEMBLY

Now the Link must be installed.

INSTALLING the Pan and Tilt Brackets WITHOUT THE LINK IS NOT ALLOWED!

The Link (see figure 3) consists of stainless steel quick links, a stainless steel
turnbuckle, and several links of stainless steel chain. The use of the chain pi eces and

One Systems, Inc. 6204 Gardendale Dr., Nashville, TN 37215 www.onesystems.com

13

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 Pole Mount System tilting bracket at the
bottom of the assembly.

The back plate sections of the PT-76a and PT-38a have eyebolts attached to them.
There are 3 eyebolts on the back plate section of the PT-76a and 2 eyebol ts on the
back plate section of the PT-38a. Figure 7 illustrates which eyebolt should be used for
each down tilt angle.

PT-76a PT-38a

Figure 7

Make sure to use the appropriate combination of Link parts to insure proper connection
between the PT bracket assembly and the specific One Systems 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. Figures 8a, 8b, and 8c show a 108IM and PT-38a at

vertical, 24 degrees and 40 degrees using the eyebolt positions shown in Figure 7. Note
that Figure 8a and 8b use the same link and turnbuckle combination but different
eyebolt locations and the Figure 8c uses chain sections as well as the quick links and
the turnbucklel

Figure 8a

Figure 8a represents the Link assembly with the enclosure in a vertical orientation and
the Link using the lower eyebolt position

One Systems, Inc. 6204 Gardendale Dr., Nashville, TN 37215 www.onesystems.com

15

Figure 8b

Figure 8b represents the Link with the enclosure in a 24 degree tilt. The Link is using
the top eyebolt and the turnbuckle has been adjusted to provide mild tension.

Figure 8c

Figure 8c represents the Link assembly with the enclosure in a 40 degree tilt. The Link
assembly uses the top eyebolt and the stainless steel chain has been added to achieve
the proper tension on the assembly. Notice the “dropped” chain links in Figure 8c.

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 is still slight tension on
the turnbuckle.

Figure 9 below shows a 312CIM mounted to a PT-76a. The down tilt is 35 degrees so
the top eyebolt is utilized as per Figure 7.

One Systems, Inc. 6204 Gardendale Dr., Nashville, TN 37215 www.onesystems.com

16

Figure 9

Figure 9 represents the maximum down tilt angle of 35 degrees from vertical. Note that
because the down tilt angle is 35 degrees the top eyebolt has been used, again per
Figure 7.

Figure 10 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.

Secondary safety cables are STRONGLY recommended and should be
secured to a structural point NOT associated with the PT bracket or
loudspeaker. The Link assembly is NOT a secondary safety cable.

PT-10 Installation

The One Systems PT-10 is designed for use with the 103IM and 106IM family of One
Systems products only .

DO NOT SUBSTITUTE OTHER LOUDSP EAKER ENCLOSURES!

The PT-10 has been designed as a low cost yet flexible pan and tilt system and is
intended for use with small format, low Q loudspeaker systems. The PT-10 offers 10
degree aiming increments and will provide up to 5 steps within the nominal 100 degree
pattern of either the 103IM or the 106IM. Figure 11 represents the PT-10 pan and tilt

bracket.

Figure 11

There are two center pieces that may be used for aiming with the PT-10 bracket. Each
“center piece” offers aiming resolution of 20 degrees but substitution of the center
pieces will yield aiming resolution of 10 degrees.

Figure 12a shows the two center pieces. The 10 degree aiming resolution is achieved
by substituting the appropriate center piece to achieve a TOTAL resolution of 10
degrees between the two center pieces. These two center pieces are interchangeable
and may be used to set the desired angles.

Note the “rotated clock” section in “Part 2” of Figure 11a below. This section is rotated
10 degrees from the part labeled “Part 1” and is what allows the aiming increments to
be adjusted in 10 degrees steps.

One Systems, Inc. 6204 Gardendale Dr., Nashville, TN 37215 www.onesystems.com

18

FIGURE 11a

Figure 12 shows a One Systems 103IM mounted to a PT10. There are 4 M5 stainless
steel bolts that are supplied with the PT-10 for mounting to either the 103IM or the
106IM. Once the PT-10 is mounted to the specific loudspeaker enclosure the two
stainless steel bolts on the center piece of the PT-10 may be loosened to allow the
bracket to be rotated in both the “pan” and “tilt” axis. Once proper loudspeaker aiming is
achieved both of these bolts must be securely fastened to insure the assembly will not
move.

NOTE: It is strongly recommended that a “temporary” thread locker be used to secure
the two M6 bolts that set both the pan and the tilt angles of the PT-10.

NOTE: It is necessary to fit an additional/secondary safety assembly
between the loudspeaker enclosure and the mounting surface. This safety
assembly is not supplied by One Systems. The safety assembly must
conform to local and national codes!

Figure 12

One Systems, Inc. 6204 Gardendale Dr., Nashville, TN 37215 www.onesystems.com

19

Secondary safety cables MUST be used with the PT-10 and should be
secured to a structural point NOT associated with the PT bracket or
loudspeaker. This secondary safety should be connected between the
loudspeaker and the mounting surface!

PT-30 Installation

The PT-30 is available in two versions. The “standard” version is made with 304 grade
stainless steel. The PT-30 is also available in a “Marine grade” version that uses 316
grade stainless steel. The PT-30 was designed for use on small diameter round and
square/rectangular poles.

See important note on page 3 regarding mounting in “Marine” environments!

For square/rectangular poles the minimum flat dimension must be 3.75 inches
(95.25mm) and for round poles the minimum required diameter is 4 inches (101.6mm).
The PT-30 was designed for use with the 108IM and its transformer variants and for the
208CIM and its transformer variants only. NO SUBSTITUTIONS ARE ALLOWED!

NOTE: One Systems does not imply suitability of specific pole diameters. Each pole
must be verified by the pole manu fact ur er or ot hers as to the struc tural suitability of the
pole for use with the total load of the PT-30, the loudspeaker, and all required safety
factors.

THE PT-30 is designed for pole mounting ON LY ! DO NOT wall mount the PT-30!

The PT-30 is shown below. The PT-30 allows a down tilt of 40 degrees i n 8 deg r ee
increments.

The PT-30 has three slots for mounting the back bracket assembly on a pole. ALL
THREE slots MUST be used. Each slot MUST be DOUBLE WRAPPED (two
INDEPENDENT bands per slot!) using the specified Band-It straps ONLY! DO NOT
substitute any other straps. IT IS NECESSARY TO USE ALL MOUNTING SLOTS TO
INSURE A SAFE AND SECURE MATE TO THE ASSOCIATED SURFACE!

IT IS CRITICAL THAT THE MATING SURFACE (Pole) BE CAPABLE OF
SUPPORTING THE LOAD OF THE PT-30 BRACKET, THE 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 (Pole)
ARE UNDERSTOOD. DO NOT INSTALL THE PT BRACKET AND LOUDSPEAKER IF
THE MATING SURFACE (Pole) IS NOT CAPABLE OF SUPPORTING THE ENTIRE
ASSEMBLY WEIGHT, AS WELL AS PROVIDIN G THE REQUIR ED SAF E TY
FACTORS!

IMPORTANT: There are 3 slots indicated by the red arrows in the image below. Each of
the 3 slots must be utilized to insure a secure mount to a pole. ALL 3 slots must use
double wrapped bands (Two independent bands wrapped in each slot)! The image
below shows the PT-30 mount to a round pole. As shown, ALL three band slots must be
used and all locations MUST be double wrapped (two independent band assemblies per
slot!)

Now the M8 forged shoulder “eye” bolt should be installed in the top rear of the
loudspeaker enclosur e. Make sure that that eyebolt is seated on the enclosure surface.

Note that the desired pan and tilt angles may be set either before or after the
loudspeaker is mounted to the PT-30 assembly. However, the pan and tilt angle

adjustments must be double checked and tightened after the loudspeaker has been
mounted.

Next, the loudspeaker should be mount ed to the PT-30 using the supplied M8 stainless
steel bolts and internal tooth lock washers. DO NOT SUBSTITUE ANY PARTS.

PT-30 speaker mount bracket section

The PT-30 mounts to the top or bottom of the 108IM or 208CIM as shown in the figure
below using the M8 locations. The mounting locations are highlighted in red.

Note: Remove all 7 M8 cover plugs before installing the loudspeaker on the PT-30
bracket plate!

DO NOT SUBSTITUTE MOUNTING LOCATIO NS!

PT-30 Mounting locations (top or bottom) for 108IM/208CIM

There are mounting locations on both the top and bottom of the 108IM/208CIM and
either the top or bottom may be used. Then enclosure may be oriented with the high
frequency section either at the top or bottom of the configuration.

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 PEOPLE ARE REQUIRED TO MOUNT THE LOUDSPEAKER ENCLOSURE TO
THE POLE AND PT brackets. Safety harnesses should always be worn when working
from an elevated platfo r m.

Once both the tilt and pan angles are set, make sure that all bolts are tight and secure.
UNDER NO CIRCUMSTANCES SHOULD THE LOUDSPEAKER DO WN TILT

EXCEED 40 DEGREES FROM VERTICAL FOR THE PT-30!

LINK ASSEMBLY

Now the Link must be installed.

INSTALLING the Pan and Tilt Bracket WITHOUT THE LINK IS NOT ALLOWED!

The Link consists of stainless steel quick links, a stainless steel turnbuckle, and several
links of stainless steel chain. T he 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 Pole Mount System tilting bracket at the bottom of the assembly.

The back plate section of the PT-30 has two eyebolts attached to it. The figure below
illustrates the proper eye bolt to use for each down tilt angle of the bracket.

PT-30 EYE BOLT AIMING LOCATIONS

Make sure to use the appropriate combination of Link parts to insure proper connection
between the Pole Mount System and the specific One Systems 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 figures below show a 108IM or 208CIM and PT­30 at vertical, 24 degrees and 40 degrees using the eyebolt positions shown in the “PT­30 EYE BOLT AIMING LOCATIONS” image. Note that Figure 8a and 8b use the same
link and turnbuckle combination but different eyebolt locations and the Figure 8c uses
chain sections as well as the quick links and the turnbuckle.

Figure 8b

Figure 8b represents the Link with the enclosure in a 24 degree tilt. The Link is using
the top eyebolt and the turnbuckle has been adjusted to provide mild tension.

Figure 8c

One Systems, Inc. 6204 Gardendale Dr., Nashville, TN 37215 www.onesystems.com

28

Figure 8c represents the Link assembly with the enclosure in a 40 degree tilt. The Link
assembly uses the top eyebolt and the stainless steel chain has been added to achieve
the proper tension on the assembly. Notice the “dropped” chain links in Figure 8c.

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 and there is slight tension on the
Link assembly.

Figure 10 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 10

Secondary safety cables are STRONGLY recommended and should be
secured to a structural point NOT associated with the PT bracket or
loudspeaker. The Link assembly is NOT a secondary safety!

APPENDIX 1

(Projected Area Values)

The values below should be supplied to the specific pole manufacturer for safety
calculations. These values were determined by adding the projected areas of the high
frequency horns, the woofer cones and ports to the cross sectional area of the front of
each enclosure listed below. Each enclosure will present a different EPA based on wind
direction. The values listed below are for wind loads directly into the front of the
enclosure and represent maximum values.
