Adamson Systems Engineering, based in Port Perry, Ontario, will introduce the S-Series at Prolight + Sound from April 15-18, 2015, in Frankfurt, Germany (Hall 8 – Stand 50). The new sub-compact line array system comprises the S10 line array enclosure, S119 subwoofer, Blueprint AV and the E-rack, Adamson’s new unified rack solution.
The S10 is a 2-way, full range, sub-compact line array enclosure designed for mid-size arenas, theaters, churches and dance clubs, as well as outdoor festivals. It is loaded with two newly designed 10-inch ND10-LM Kevlar neodymium low frequency drivers and an NH4TA2 1.5-inch exit high frequency compression driver mounted to a wave shaping sound chamber that produces a slightly curved wavefront with a nominal dispersion pattern of 110x10 degrees (HxV). It measures 10.4x29x207 inches and weighs 60 pounds.
Due to extensive boundary element testing, the chamber is said to exhibit increased vertical response with minimal sacrifice of high-frequency energy in the far field. The S10 offers a stated output of 141.3 dB max peak SPL.
The S10 enclosure offers Adamson’s patent-pending Controlled Summation Technology, a design method that brings the LF drivers as close together as possible, while symmetrically outwardly splaying them. The end result increases usable frequency range while decreasing summation at the crossover point, reducing interference. The LF drivers are also recessed behind the exit of the HF sound chamber, so as to not limit the size and shape. A small amount of delay aligns the low frequencies to the high-frequency energy, with some dynamic overlap control in place as well to diminish any remaining noticeable interference.
The companion S119 subwoofer is loaded with a lightweight, long excursion 19-inch ND19 Kevlar Neodymium driver usng Adamson’s Advanced Cone Architecture and a 5-inch voice coil for exceptional power handling. It is mounted in an ultra-efficient front-loaded enclosure, designed to reproduce clean, musical low frequency information.
The cabinets for both the S10 and S119 enclosures are constructed of marine grade birch plywood, aircraft grade steel and aluminum and feature Speakon NL8 connectors. The S-Series uses Adamson’s new SlideLock Rigging System, which allows angles to be set prior to lifting, which then fall into place when weight is taken. A stacking pin is also present to maintain proper enclosure angles when ground stacked. The S10 enclosure is also available as the S10i, using a plated rigging system for permanent installation. The S10i’s slimmed down rigging reduces the weight and cost of the enclosure.
The S-Series is designed to be powered by the E-Rack, Adamson’s unified rack solution that interfaces with and powers the S Series as well as the full range of Adamson loudspeaker products.
The E-Rack incorporates Lab.gruppen amplification, combined with versatile I/O and industry standard power connections, as well as a 20-port managed Ethernet switch to route dual-redundant Dante and control signal. E-Racks are sold in 8-channel or 12-channel configurations with Lab.gruppen’s PLM 12K44 amplifiers. Adamson states that one 12-channel E-Rack can power up to 24 S10 enclosures. Each E-Rack includes a personal license for Adamson's Blueprint AV software.
S-Series accessories include the S10 Support Frame, S10 Extended Beam, S10 Underhang (to adapt S10 to fly as an underhang with either the E15 or E12), S10 Dolly, S10 4up Cover and Dolly Stacking Legs, which are also used to increase or decrease tilt in either the E15 or E12 dolly.
