IS7
• The IS7 is an ultra-compact line array enclosure designed for medium throw applications. It contains two
symmetrically arrayed 7” LF transducers and a 3” HF compression driver mounted onto an Adamson sound
chamber. The high frequency sound chamber is designed to couple multiple cabinets across the entire intended
frequency band without loss of coherence.
• The operational frequency range of the IS7 is 80 Hz to 18 kHz. The use of proprietary technologies such as
Controlled Summation Technology and Advanced Core Architecture allow high maximum SPL and maintains a
consistent nominal horizontal dispersion pattern of 100° down to 400 Hz.
• The enclosure has an unobtrusive visual design which blends seamlessly into the surrounding space, is made of
marine grade birch plywood, and has a four-point rigging system. Without sacricing low resonance to composite
material, the IS7 weighs only 14 kg / 30.9 lbs.
• Up to sixteen IS7 can be flown in the same array when using the IS7/IS118 Rigging Frame and up to eight when
using the IS7 Micro Frame. Nine rigging positions are available, allowing vertical inter-cabinet splay angles from
0° to 10°. Always consult Blueprint AV™ and the IS-Series Line Array Rigging Manual for correct rigging positions
(including ground stacking options) and installation procedures.
• The IS7 is intended to be used as a standalone system or with the IS118 companion subwoofer, which brings the
usable frequency range down to 35 Hz. The IS7 can also be paired with other IS-Series subwoofers.
• The IS7 is designed for use with Lab.gruppen’s D-Series line of installation ampliers. The nominal impedance of
the IS7 is 16 Ω per band, maximizing amplier efciency.

The Adamson LoadLibrary (http://adamsonsystems.com/support/downloads-
directory/design-and-control/e-rack/245-adamson-load-library-5-0-1/le) contains
presets designed for a variety of IS7 applications. Each preset is intended to be phase-
linear with either the IS118 or IS119 subwoofers.
Array Shaping overlays (found in the Array Shaping folders of the Adamson Load Library) can be recalled in the EQ
section of Lake Controller to adjust the contour of the array. Recalling the appropriate EQ overlay or preset for the
number of cabinets being used will give the standard Aamson frequency response of your array, compensating for
different low-frequency coupling.
Tilt overlays (found in the Array Shaping folders of the Adamson Load Library) can be used to alter the overall acoustic
response of an array. Tilt overlays apply a lter, centered at 1kHz, which reaches the noted decibel cut or boost at the
extreme ends of the listening spectrum. For example, a +1 Tilt will apply +1 decibel at 20 kHz and -1 decibel at 20 Hz.
Alternately, a -2 Tilt will apply -2 decibels at 20 kHz and +2 decibels at 20 Hz.
Please refer to the Adamson PLM & Lake Handbook for detailed instructions on recalling Tilt and Array Shaping
overlays. https://adamsonsystems.com/support/downloads-directory/design-and-control/e-rack/205-adamson-

When cabinets and subwoofers are positioned separately, phase alignment
should be measured with suitable software.

Weatherized
IS-Series weatherized models add an additional layer of environmental and corrosion protection to Adamson’s already
durable cabinet design. Weatherized enclosures are ideal for marine and coastal venues, outdoor stadiums, open-air
performance spaces, and other permanent outdoor installations.
IS-Series weatherized cabinets feature the following additional protective features.
Corrosion resistance
Corrosion resistance extends the lifetime performance of your system in outdoor venues where water, salt and acidity
can impact durability and function.
All structural steel elements of Adamson weatherized cabinets – including rigging and rigging links – are made of a
high yield strength stainless steel alloy that offers 100% corrosion resistance.
Cabinet hardware is made of non-plated stainless steel, designed to provide exceptional rust and corrosion resistance,
particularly in high-saline environments.
Environmental sealing
Additional protection of the cabinet helps ensure that loudspeaker performance isn’t impeded by the harsh
environments in which your system is deployed.
To guard against water and particle intrusion, the same two-part polyurea coating that gives Adamson cabinets their
life-extending exterior protection is applied to the interior of the enclosure, creating a complete seal. Weatherized
models feature an exterior coating with a distinctive smooth nish that allows for easy cleaning and removal of
contaminants like dirt, grime, salt water or sand.
To protect against dust and other particles, a ne stainless steel mesh has been added to all points of entry including
behind the front grille screens.
Cabling for the IS-Series weatherized cabinets is pre-wired and protected inside a gasket-sealed jackplate, with gland
nuts in place to seal the connection points.
