"Two MEGA-112 as top parts as well as one MEGA-118SUB were brought to the test. We used the power amplifiers STA-600 and STA-1400 for the top parts in bi-amping and the STA-1000 for the bass reproduction. For the functional control, we applied the digital speaker management DSM-260. The units were tested in a small factory building ... it featured many windows, a concrete floor and several tiled surfaces, allowing the high frequencies to show no mercy ... however, with the precise equalizers of the DSM-260, we were able to tame these very quickly ... the unit allows to optimise the sound quickly and intuitively ... we turned the volume up and achieved an impressive performance. The subwoofer is very stable and provides a really powerful sound. The MEGA-112 impresses by a really well-balanced sound. Full and dynamic dance music with a really great sound can thus be achieved. This PA system is able to easily provide a professional sound for 400 guests, even for the more sophisticated listener. Thumbs up. The selected PA combination is very suitable for everyone performing at temporary locations."

"The power amplifiers STA-200D and STA-1000D from IMG Stage Line impress by an elaborated selection and configuration of the inner components. Due to the low weight and the mounting depth of 335 mm only, this series is suitable for both rack mounting and installation into shelves. With these test results, they are also suitable for hi-fi applications. I consider these 'lightweights' to be very well-suited for small to medium-sized entertainment applications, PA applications at conferences and for speech transmissions well as a multi-channel power amplifier for stage monitoring."

"The plastic housings are of neat workmanship ... the MMX-842USB is a good choice ... the STA-225 features all standard protective circuits, even a clip limiter can be switched on additionally.

The system tested provided a really appealing sound: a nice deep bass reproduction and a clear midrange of the 12" speakers and a full and clear reproduction of the high frequencies, too. With the support of a subwoofer, the volume which can be achieved is already sufficient to show a great performance at smaller to medium-sized events.
