| Heed all warnings and follow all instructions.
| A qualifi ed technician must be present during the installation and use of this product. This product is capable of producing extremely high sound pressure levels and should be used according to the specifi ed local sound level regulations and good judgement. Adamson Systems Engineering will not be liable for damages caused by any possible misuse of this product.
| Servicing is required when the loudspeaker has been damaged in any way, such as when the loudspeaker has been dropped; or when for undetermined reasons the loudspeaker does not operate normally. Inspect your products regularly for any visual or functionality irregularities.

Protect the cabling from being walked on or pinched.

Read the appropriate IS-Series Rigging Manual before installing the product.

Pay attention to rigging instructions included in both Blueprint AV™ and the IS-Series Rigging Manual.

Use only with the rigging frames/accessories specifi ed by Adamson, or sold with the loudspeaker system.

This speaker enclosure is capable of creating a strong magnetic fi eld. Please use caution aroundm the enclosure with data storage devices such as hard drives

IS7 Ultra Compact Line Array

• 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 sacrificing 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 AVTM 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 amplifiers. The nominal impedance of the IS7 is 16 per band, maximizing amplifier efficiency.

Wiring

• The IS7 (971-0003, 971-5003) comes with 2x Neutrik SpeakonTM NL4 connections, wired in parallel.
• The IS7b (971-0004, 971-5004) comes with an external barrier strip.
• Pins 1+/- are connected to the 2x ND7-LM8 MF transducers, wired in parallel.
• Pins 2+/- are connected to the NH3-16 HF transducer.

Amplification

The IS7 is paired with Lab.gruppen D-Series amplifiers.

Maximum quantities of the IS7 per amplifier model are shown below.

For a master list, please refer to the Adamson Amplification Chart, found on the Adamson website.

Presets

The Adamson LoadLibrary (http://adamsonsystems.com/support/downloadsdirectory /design-and-control/e-rack/245-adamson-load-library-5-0-1/file) contains presets designed for a variety of IS7 applications. Each preset is intended to be phaselinear with either the IS118 or IS119 subwoofers. When cabinets and subwoofers are positioned separately, phase alignment should be measured with suitable software.

Control

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 filter, 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-adamsonplm-lake- handbook/file

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 finish that allows for easy cleaning and removal of contaminants like dirt, grime, salt water or sand.
To protect against dust and other particles, a fine 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.
