The Self-Powered Advantage

	A new, three-channel class AB/H amplifier provides 1275 watts total burst output (2550 watts peak) power to M’elodie.

Having manufactured self-powered sound reinforcement loudspeakers since 1995, Meyer Sound has pioneered and refined this technology to produce systems that are powerful and reliable. Self-powered systems eliminate heavy, expensive, amplifier racks and large loudspeaker cables, thereby lowering costs. With no need to calibrate gain and crossover settings, self-powered systems are easy to use and go from the truck to fully rigged and back in minutes.

M’elodie features an all-new, three-channel class AB/H amplifier conservatively rated at 1275 watts total burst output (2550 watts peak). The amplifier/processing module is field replaceable and includes limiting to extend driver life and hold long-term power compression to a minimum. Meyer Sound’s Intelligent AC power supply automatically adjusts for any line voltage worldwide and provides both soft turn-on and transient protection.

Like all Meyer Sound self-powered systems, M’elodie contains all of its amplification and processing circuitry within the cabinet, yielding greater performance, lower overall system cost, and extremely fast setup and teardown.

The increase in performance comes from all of the components being designed as an integrated system from the beginning, rather than being designed separately and then married together. Compromises to accommodate unknown amplifiers or loads in passive systems are entirely eliminated, as are signal losses from long loudspeaker cable runs.

Self-powered systems also enable complete consistency: each component that goes into a M’elodie cabinet is tested at the factory to insure it performs identically to every other, and final testing is done to confirm consistency of each complete system. Consistency is critical in line array applications, where performance differences corrupt the coupling between cabinets that is the basis of line array theory.
