Product description

The GSL8 is a line array module specifically designed for largescale sound reinforcement. Up to twenty-four GSL8 loudspeakers can be flown in vertical columns producing an 80° constant directivity dispersion pattern in the horizontal plane. The GSL8 houses two 14" neodymium forward facing LF drivers and two side firing 10" neodymium LF drivers. A coaxial mid-high section contains an MF horn with a 10" driver and three 1.4" exit, 3.4" voice coil HF compression drivers mounted to a dedicated wave shaping device. SL-Series flying hardware comes with a patended workflow with integrated tension and compression rigging mode, allowing splay angles between cabinets from 0° to 7° in 1° increments. The loudspeakers are driven actively by two channels of an appropriate d&b amplifier, one channel powering the 14” LF drivers, the second channel powers all other components, these are passively crossed-over. This component geometry allows for a smooth crossover design with well-defined overlaps between adjacent bands providing consistent, even and very accurate horizontal dispersion. Due to the arrangement of the front and side firing LF drivers, accurate directivity control is maintained from 45 Hz to above 18 kHz. The cabinets are constructed from marine plywood and have an impact and weather protected PCP (Polyurea Cabinet Protection) finish. The front and side panels incorporate rigid metal grills backed by an acoustically transparent and water repellent fabric. Each side panel incorporates a recessed handle, with additional handles are provided at the rear.

Amplifiers

The d&b D80 amplifier is required to drive the GSL8. The 2-Way active GSL8 requires two channels of the D80.
