1Introduction
O-Line™ 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 O-Line™ 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 O-Line™ 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.
3Warranty
Martin Audio O-Line™ products are warranted against manufacturing defects in materials or craftsmanship over a
period of 5 years from the date of original purchase.
During the warranty period Martin Audio will, at its discretion, either repair or replace products which prove to be
defective provided that the product is returned in its original packaging, shipping prepaid, to an authorised Martin Audio
service agent or distributor.
Martin Audio Ltd. cannot be held responsible for defects caused by unauthorised modifications, improper use,
negligence, exposure to inclement weather conditions, act of God or accident, or any use of this product that is not in
accordance with the instructions provided by Martin Audio. Martin Audio is not liable for consequential damages.
This warranty is exclusive and no other warranty is expressed or implied. This warranty does not affect your statutory
rights.
4Installationmethodsandkitdetails
A site survey is required before purchase. O-Line™ software should be used to determine the position, installation
method and number of O-Line™ modules required for the installation.

4.1O‐Line™modulepack
Each pack of O-Line™ modules comprises the following parts:

O-Line™module pack
The self-adhesive shade included in the module pack may be used to prevent down-lighting from shining down through
the grilles in architecturally sensitive locations.
There are three methods of installing an O-Line™ Loudspeaker system. Choose the position and number of O-Line™
modules required as indicated by the O-Line™ software.
The Link plates, link nuts and bolts, Linking Pins and safety clip are to enable linking blocks of four modules.
The series Linking PCB and PCB screws enable easy wiring in series between two blocks where linking in parallel
would reduce the impedance to a value lower than is suitable for your amplifier.
A self-adhesive Martin Audio badge is supplied to be attached to a complete array, usually placed on the bottom
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 O-Line grilles, we strongly recommend that you keep each block of four O-Line™
modules in their high density foam 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 high density foam tray to avoid losing them.
5.2Splayangleadjustment
O-Line™ modules are shipped with splay angles set at 0 degrees. Having determined splay angles and mounting or
suspension attachment points using the O-Line™ 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…

Martin Audio O-Line™ 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 O-Line™ loudspeaker must be fitted with a steel safety wire this can be fitted between an attachment
bracket (provided) and a suitable supporting structure.
6.1
Fit the U-bracket first having calculated the required angle for the bottom module using the O-Line software. There are
two positions in which it can be fitted, towards the top for 3-5 degrees or the bottom of the bottom module for 0-2
degrees. Use the position that will allow the linking pins to be fitted without being obstructed. Once the bracket is
attached fit the linking pins.
