Product Introduction
IS7 Ultra Compact Line Array
•
The IS7 is an ultra compact line array enclosure designed for extended throw capabilities. It has an unobtrusive
visual design which blends seamlessly into the surrounding space. It contains two symmetrically arrayed 7"
transducers and a 3" compression driver mounted on an Adamson waveguide.
•
Up to 16 IS7 can be flown in the same array when using the IS7 & IS118 Support Frame (930-0026) and up to
8 when using the S7 Micro Frame (930-0029). Due to the use of Controlled Summation Technology, the IS7
maintains a consistent nominal horizontal dispersion pattern of 100° down to 400Hz.
•
The high frequency waveguide is designed to couple across the entire intended frequency band without loss of
coherence. There are 9 rigging positions available, spanning 0° to 12.5°.
•
Adamson's use of proprietary techologies such as Controlled Summation Technology and Advanced Cone
Architecture give the IS7 an extremely high maximum SPL level of 138 dB. The nominal impedance of the IS7 is
16 Ω per band, maximizing amplifier efficiency.
•
The operational frequency range of the IS7 is 80Hz to 18kHz, +/- 3 dB.
•
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 35Hz.
•
The wooden enclosure is made of marine grade birch plywood, and has an aluminum rigging system mounted on
each corner. Without sacrificing low resonance to composite material, the IS7 is able to maintain a low weight of
13.2 kg / 29 lbs.
•
The IS7 is designed for use with Lab.gruppen's D-Series line of installation amplifiers.
In an effort to continuously improve its products, Adamson releases updated accompanying software, presets and
standards for its products. Adamson reserves the right to change the specifications of its products and the
content of its documents with no prior notice.
