Per channel LEDs for limiter, level and signal keys World 02/2012 The plastic housings are Impeccably processed ... the MMX-842USB is a good choice ... the STA-225 has all common protection circuits, even a clip limiter can be switched on and a display shows all sorts of useful information about the operation. The sound of our test system is really appealing: a nice, deep bass and clean mid-12s, plus a round, clear high-frequency range. The loudspeaker can be reached with a subwoofer for small to medium-sized events and leaves nothing to be desired with regard to performance - neither the active bass loudspeaker nor the passive parts of the loudspeakers sounded louder or even overburdened.
