POWER REQUIREMENTS
This unit requires connection to an AC volt AC outlet. Do not cut or
disconnect the ground pin on the power cord. The GLA LINE ARRAY
SYSTEM has an internal switch mode power supply and will run with a
mains voltage between 100 and 135VAC, it can be internally switched to
run at a line voltage between 220 to 240 VAC. Note: The internal power
supplies need to be switched to run at the higher line voltage.
Caution: Exposure to extremely high noise levels can
cause permanent hearing loss.
The GLA Series Line Array is capable of producing in excess of 130db SPL at 1 meter.
Continued exposure to noise levels in excess of 90db may cause permanent hearing loss.
Below is a chart of the OSHA (Occupational Safety & Health Administration) regulations for
Occupational Noise Exposure. Please note: OSHA requires hearing protection for any work
environment when the sound levels exceed those shown in Table G-16 when measured on the
A scale of a standard sound level meter at slow response.

INTRODUCTION
Thank you for your purchase of the GLA Series Line Array System. The GLA
Series is an all in one box two way multi-element line array system designed for
high performance high fidelity sound. The GLA2806, 2606 and 2406 Line
Array Speakers offer a new extremely high performance small format 2-way
“true” line array cabinet with “gapless” summation of the line array elements.
The new GLA series provides line array performance at an unheard of price
point. Now venues looking for a small format line array can have a true high
fidelity, high performance line array system without the associated high price.
All multi-box line array systems suffers from a gap between the individual
elements of the line array which can cause response errors due to the spacing
between the drivers. In many designs this will cause both frequency and phase
errors in the response which means the sound will change based on the seating
position in the room. The GLA system delivers all the advantages of a true line
array system but with a new level of precision summation between the internal
components and with the same mid-range clarity and definition that ISP has
become known for. The GLA Series provides a 32-degree vertical pattern for
the GLA2606 and GLA2406 and 48-degrees vertical by 110-degrees horizontal
pattern with extremely smooth summation between the internal elements. The
GLA series is a powered bi-amplified design featuring ISP Technologies
patented DAA Dynamic Adaptive Amplifier technology. The new DAA power
amplifier delivers efficiency close to that of Class D but with class A/B sonic
performance for both the best and warmest sound possible. The GLA series
has flypoints on top for flying and also includes a bottom cup for the 2606 and
2406 versions for stand mounting making this an excellent system for corporate
or other portable events.
