Before connecting and using this product, please read this instruction manual carefully.
Be sure to follow all the precautionary instructions in this section, which contain important warnings and or cautions regarding
safety.
The manual is to be considered as integral part of this product & must accompany it when it changes ownership as a reference
for correct installation and use as well as for the safety precautions.
Install in accordance with Studiomaster Professional's instructions and under the supervision of a licensed Professional Engineer
only.
Studiomaster Professional shall not assume any responsibility for the incorrect installation/or use of this product.
Safety symbols and messages described below are used in this manual to prevent bodily injury and property damage which could
result from mishandling. Before operating your product, read this manual first and understand the safety symbols and messages so
you are thoroughly aware of the potential safety hazards.
SAFETY SYMBOL AND MESSAGE CONVENTIONS
1. Make sure all connections have been made correctly.
2. Protect Input cables and interconnection cables from damage; make sure they are positioned in a such way that they can not be
stepped on or crushed by any object.
3. Make sure that no object or liquids can get in to the product as this may cause short circuit.
4. Never attempt to carry out any operations, modifications or repairs that are not expressly mentioned in this manual. Contact your
authorized dealer or qualified personnel if any of the following occur:
The system does not function or works in anomalous way.
The cable has been damaged.
Objects or liquid have got in to unit.
The system has been damaged due to heavy impact or fire.
5. Before placing, installing, rigging, or suspending any speaker product, inspect all hardware, suspension, cabinets, transducers,
brackets and associated equipment for damage.
6. Any missing, corroded, deformed, or non-load rated component could significantly reduce the strength of the installation,
placement or array. Any such condition severely reduces the safety of the installation and should be immediately corrected.
7.
Never exceed the rating of the hardware or equipment.
Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface. Doing so may result in
the unit falling down and causing personal injury and/or property damage.
9. Refer all installation work to the dealer from whom the speaker was purchased. Installation for flying requires extensive technical
knowledge and experience. The speaker may fall off if incorrectly installed, resulting in possible personal injury.
10. For Flying be sure to follow the instructions below. Otherwise, the suspension wires or belts may be off or snap and the speaker
may fall off, causing personal injury.
Check to confirm that the suspension wires and belts are strong enough to withstand the speaker load.
The connectors of the suspension wires and belts must be securely linked with those of the speaker.
11. Install the unit only in a location that can structurally support the weight of the unit and the mounting bracket. Doing otherwise
may result in the unit falling down and causing personal injury and/or property damage.
12. Owing to the unit's size and weight, be sure that two or more persons are available to install the unit. Failure to do so could result
in personal injury.
8.
Use only recommended hardware, brackets, joining plates, locking pins etc which are supplied with the unit
for the installation.

2. Important Safety Precautions
Indicates a potentially hazardous situation which, if mishandled,
could result in moderate or minor personal injury, and/or property damage.
Indicates a potentially hazardous situation which, if mishandled,
could result in serious personal injury.
3
1. Do not operate the unit for an extended period of time with the sound distorting. This is an indication of a malfunction, which in turn
can cause heat to generate and result in a fire.
2. Do not stand or sit on, nor hang down from the unit as this may cause it to fall down or drop, resulting in personal injury and/or
property damage.
3. Should the unit emit any strange odours or smoke, remove it from line after having the amplifier switched off.
4. Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level that leads to hearing loss is different
from person to person and depends on the duration of exposure. To prevent it wear ear plugs or protective earphones.
14. Do not use other methods than specified to mount the bracket. Extreme force is applied to the unit & the unit could fall off, possibly
resulting in personal injuries.
15. Tighten each nut and bolt securely. Ensure that the bracket has no loose joints after installation to prevent accidents that could result
in personal injury.
16. Do not mount the unit in locations exposed to constant vibration. The mounting bracket can be damaged by excessive vibration,
potentially causing the unit to fall, which could result in personal injury.
3. Introduction
Thank you for purchasing the Studiomaster Professional SLA 30 Active Compact Line Array System. To ensure
optimum performance & safety, please follow this instruction manual carefully. Please retain this manual for future
reference. For any complaint, feedback or testimonials please contact our distributor / dealer.
The SLA 30 is a specially designed loudspeaker module designed to form a vertical stack in varying numbers. This
stack is usually flown to provide superior sound coverage in the intended listening areas. Stacked SLA 30 modules
form a line array for constructive summing and increased coupling. Sound dispersion of SLA 30 array has a very
narrow vertical dispersion angle. Therefore sound can be precisely directed where audience is present.
The SLA 30 has a maximum hinge of 10°, variable in steps of 2°. This hinge is enough to provide necessary tilt in
a typical J or spiral array. The SLA 30 is capable of producing peak SPL of 123dB with its Single LF driver & twin
HF drivers. For achieving even sound pressure levels in the audience areas, SLA 30 is provided with a switch for
altering its sensitivity from nominal 0dB to -3dB & +3dB. The SLA 30 has a full frequency response ranging from
85Hz to 19kHz.
Important Concept of Line Array:
In the case of normal loudspeakers, as sound travels, its SPL (Sound Pressure Level) falls by 6dB for every
doubling of distance. In the case of a Line Array the fall in SPL is 3dB for every doubling of distance up to a
certain distance called transition point. Beyond that the fall in SPL is 6dB for every doubling of distance as in
the case of normal loudspeakers.
The transition point is dependent on the length of the line array. Longer the array, further away is the transition
point. Therefore if near equal SPL is desired spanning the front row to the last row, it is recommended to have
more numbers of SLA 30 enclosures stacked vertically in spiral formation.
SLA 30: The SLA30 incorporates 1 x 8” Woofer and
2 x 1.5” HF with state of the art Waveguide horn, all
comprised into a sleek & lightweight enclosure. This
Array module has a horizontal coverage angle of 100°
& vertical Coverage angle of 10°.
SLA 30 System Consists of:

About Waveguides:
Sound Waves in open space propagate in all directions, this way they lose their
power significantly. In order to counter this problem the SLA-30 incorporates
waveguide driver to ensure maximum control on power & dispersion. This ensures
pure performance and negates the possibilities of phase cancellations.
SLA 30 Kit: The SLA 30 Kit is set of essential
hardware required for rigging & flying this line array
system. It consist of ultra durable Flybars / Array
Frames & Quick Release Pins (Push-Pull Bullets). This
kit makes flying the SLA 30 Series a very easy.

5. Rear Panel Artwork:
1. Balanced input that can be used for connecting an audio source with high level signal output
(e.g. preamplifier, mixer, cassette recorder, CD player, musical instrument, etc.).
Audio Input (Balanced Input):
2. Audio output can be used to send Audio signal to other amplifier speakers, recorders or supplementary
amplifiers or to loop other SLA 30.
Audio Output:
3. HF can be boosted by +3dB or can be cut by -3dB for improved performance.HF Selection Switch:
The -3 dB position will typically be used for the speaker(s) in an array that are covering the nearest listening area.
The +3 dB position will be used for the speaker(s) covering the more distant areas; or to compensate for the low-frequency buildup resulting from mutual coupling of multiple woofers in an array.
