About the M1 Active Mk2 INSIDE YOUR NEW SPEAKERS ✪ If you're in a hurry to get started, skip ahead to Chapter 2, "Speaker Installation", for connection and placement tips. ABOUT POWERED MONITORS The M1 Active Mk2s combine a speaker and amplifiers in the same compact cabinet. Powered monitors are growing in popularity over the traditional separate amplifier and speakers for a number of reasons, convenience and ease of hookup being only one of them. You can connect a powered speaker directly to any line-level source (normally, the control room output of a mixer) simply by connecting a patch cord. Another benefit is improved sound quality. With careful design, the speaker, amplifier and electronic crossover can be optimised for each other. The M1 Active Mk2s are biamplified, meaning that low frequencies and high frequencies are handled not only by separate speakers (the tweeter and the woofer), but by separate amplifiers. A pair of M1 Active Mk2s contain a total of four power amplifiers. Because of the increased efficiency of biamplification, these are much louder than a single-channel power amplifier of the same wattage feeding a passive crossover, as in other designs. New technology makes it possible to make these high-wattage amplifiers small enough to fit inside the speaker cabinet, with very little weight or size gain. Since the M1 Active Mk2s are self-powered, DO NOT connect them to the speaker output of another amplifier (such as a powered mixer or hifi receiver). Connect them only to the line-level outputs of such devices (+4 dBu nominal, +24 dBu maximum). 10 M1 Active Reference Manual
