1. Introduction
Thank you for purchasing the Studiomaster Professional SLA 40 Line Array System.
To ensure optimum performance and 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 40 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 40
modules form a line array for constructive summing and increased coupling. Sound dispersion of SLA 40 array
has a very narrow vertical dispersion angle. Therefore sound can be precisely directed where audience is
present.
The SLA 40 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 40 is capable of producing peak SPL of 132dB with its dual LF drivers and
twin HF drivers. For achieving even sound pressure levels in the audience areas, SLA 40 is provided with a
switch for altering its sensitivity from nominal 0dB to -3, - 6 and -9dB. The SLA 40 has a full frequency response
ranging from 80Hz to 20kHz. However for delivery of bass frequencys, it is complemented with Subwoofer
model SLA 40S, SLA 40S is designed for ground level stacking.
SLA 40T:
The SLA40T incorporates 2 x 8”
Mid-Bass transducers & 1” High Duty HF transducer
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 40 System Consists of:
SLA40T
Dual 8", 2-Way 400 Watts @ 8 Ω, Passive Line Array Module.
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-40T incorporates
waveguide driver to ensure maximum control on power & dispersion. This ensures
pure performance and negates the possibilities of phase cancellations.
SLA 40S
Dual 15", 800 Watts @ 4 Ω, Passive Line Array Sub Woofer.
SLA 40S:
The SLA-40S incorporates 2 x 15”
Powerful Low Frequency Transducers for extended
sub filling. The enclosure is specially designed to
deliver high SPL and long excursion, without being
very bulky.
