Product Description Touring series
LM3-FF amp, Low-M Mid, loudspeaker system Self-p powered - PC remote controlled - Networking The LM3-F amp is a self-powered subwoofer cabinet designed to complement AP SK-F or SK-F amp touring system. It provides with an efficient solution when there is a need to reinforce the low frequencies within a flown cluster. The LM3-F amp cabinet is composed of 2 x 15 inch cone drivers mounted in a proprietary horn-loaded band pass system. This particular design reaches a high efficiency on-axis and reduces substantially the sound emitted toward the rear, which prevents from unwanted low frequency feedbacks on-stage. The LM3-F amp uses the same cabinet shape and L-track flying hardware as the SK-F amp system. The combination of SK-F and LM3-F amp’s cabinets gives a very powerful full range system down to 55Hz. The LM3-F amp built-in electronics package features a new power biamplifier designed specifically for SelfPowered products. The total average efficiency of extraordinary 85% renouces any moving parts
inside, lihe cooling fan, making thus the system pratically service free. The powerful, lightweight amplifier adds only 3 Kg to the weight of the cabinet while supplying 1’450 Watts of RMS power. The Power Amplifier Module is a sophisticated class-T Digital Amplifier capable of delivering more then 2x725W RMS into 4ohms. Class-T amplifiers offer both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers. It incorporates digital signal processor (DSP) providing loudspeaker specific Filtering, EQ, Delays and Protection functions. A standard Firewire connector allows to create ad-hoc networks with the help of dedicated software. Available optionally, an EtherSound embedded RJ-45 port adds networking capabilities providing bi-directional control and monitoring data in real time which eliminates the need for separate cables for the control and monitoring of equipment. The entire network can be configured, monitored and controlled from a single PC and EasyUser software.
IDEAL FOR Touring Concert halls Clubs Discotheques Festivals The LM3-F amp cabinet is the ideal complement to the SK amp full-range system. It delivers precise low-mid frequencies at high sound pressure levels within a flown array
