1 Introduction
Omniline® is a versatile, micro-line array designed for installation in a wide variety of
architectural environments.
It’s modular approach and scalability extends its use from foreground applications to
sound reinforcement in large acoustic spaces.
Intelligent software enables an array to be configured to deliver sound precisely over
any vertical angle to fit the venue profile without spilling onto surfaces where sound is
not required.
Additionally, elimination of high frequency side-lobes gives Omniline® the advantage
over currently available DSP steered columns, making it suitable for high quality
music reproduction as well as speech in large, reverberant spaces.
2 Main features
The Omniline® module consists of 2 x 89mm reflex-loaded, mid/low radiators either
side of a central strip of 5 x 14mm HF devices in a unique, patent pending
arrangement. All drives have been painstakingly developed from the ground up,
specifically for the array module.

5 Unpacking
Every Martin Audio loudspeaker is built to the highest standard and thoroughly
inspected before it leaves the factory.
After unpacking the system, examine it carefully for any signs of transit damage and
inform your dealer if any such damage is found.
We suggest that you retain the original packaging so that the system can be
repacked at a future date if necessary. Please note that Martin Audio and its
distributors cannot accept any responsibility for damage to any returned product
through the use of non-approved packaging.

5.1 System preparation
To avoid flattening or damaging your OmniLine grilles, we strongly recommend that
you keep each block of four Omniline® modules in their polystyrene trays.
Take off the rear covers by removing the rear screws from each unit.
Tips!
1) If you are not using a magnetic screwdriver, we recommend covering the
rear port holes with some tape as shown above to prevent dropping screws
down the ports!

2) Press the screws into the front of the polystyrene tray to avoid loosing
them.
5.2 Splay angle adjustment
Omniline® modules are shipped with splay angles set at 0 degrees. Having
determined splay angles and mounting or suspension attachment points using the
Omniline® software, set the required inter-module splay angles as follows:
Tip!
Leave modules that require wall mounting or suspension attachments (see software
recommendations) until last as these brackets need to be orientated and fitted before
nearby link pins are inserted – see later…
1) Remove the rear cover
2) Remove the orange safety clip
3) Remove the linking pins from the splay angle holes

Remove the Orange Safety clip
Remove the link Pins

Tip!
If the linking pins are difficult to remove, loosen the four link plate nuts and bolts for
that module. Don’t forget to re-tighten them after you have positioned the link pins
Loosen the Link Plate Nuts and bolts if necessary
4) Angle the Omniline® modules to the required splay angle lining up the link
plate holes at the required angle positions marked on the bracket
Link plates holes lined up for 5deg splay

5) Insert the four linking pins into the aligned link plate holes.
6) Replace the orange safety clip after positioning all four linking pins…

4-Omniline®module wall mounting
To remind you:
Martin Audio Omniline® loudspeakers must be installed by experienced
loudspeaker installation personnel using the full installation kit provided
It is the installer’s responsibility to ensure that all relevant local, national and
international electrical, fire and building safety regulations are complied with
Every Omniline® loudspeaker must be fitted with a steel safety wire this can

structure.
6.1
Fit the U-bracket first – and then the linking pins.
Note that the recommended U-bracket position is on the second OmniLine unit from
the bottom of the arrays.
Its final orientation will be determined by the required linking pin positions – one way
round for 0-2 degrees, the other way round for 3-5 degrees.
U-bracket (shown positioned for 4 degree linking pin position)

6.2
If you haven’t already prepared Omniline® module splay angles as indicated by the
Omniline® software – see section 5.2 above…
6.3
Fit the Collar to the U-bracket using the FAA10004 M10 x 75 bolt. Note the
orientation – collar towards the top of the array (left on the photograph)
1) Tighten the M10 bolt – tight enough so that it protrudes at least 1.5 thread
turns through the lock nut but still allows U-bracket movement for easy
adjustment.
2) Fit the FAA08005 M8 x 60mm bolt (see kit identification pictures earlier)
loosely to the collar as shown above
6.4
Wire up the array.
See separate document entitled Powering your Omniline®.

6.5
Fit rear the rear covers - using the cut out version for the module with the bracket
6.6
1) Fit the HAM02012 Wall Bracket – see kit identification picture earlier. A drilling
template is included with the bracket
Lift the block of four Omniline® modules onto the wall mounting – see below.
2) Fit the FAA08004 M8 x 40 bolt and adjust screw to set vertical tilt angle
3) Tighten clamping bolt (FAA08005 M8 x 60) after setting the horizontal angle
4) Check that the M10 x 75 collar-to-U-bracket bolt is firmly screwed into its
locking nut
Recheck everything!
ALLWAYS double check that all Orange safety clips are in place as this is essential to
ensure that the array will stay safely locked together

All material © 2009. Martin Audio Ltd. Subject to change without notice. 17

5) Remember to add the safety clips!
6) Wire the 4-module blocks together into bigger blocks of 8 or 12 modules*
using the connector pcb supplied with each block of four OmniLine® modules.
* See separate document entitled Powering your Omniline® for further
details.
Notes:
White = -ve and Orange = +ve
Upper and lower block connections are marked on the pcb.
Route the wires between the linking pins to avoid crushing them when
the rear covers are replaced.
All material © 2009. Martin Audio Ltd. Subject to change without notice. 18

7) Screw the pcb to the inside of the most convenient rear cover using the self
tap screws provided with each set of four modules. Its orientation will depend
on that module’s linking pin positions.
7.2
Fit the U-bracket to the lower OmniLine® module first – and then the linking pins.
Final U-bracket positioning will be determined by the required linking pin positions –
one position for 0-2 degrees and the other position for 3-5 degrees. See illustration
below…
