"The key to good performance is a good monitor."

The SMX 12A has been designed as a reliable multi-purpose, self-powered unit. It is a compact yet powerful tool for various monitoring requirements on and off stage. Eight DSP presets simplify the setup and tuning of the system. Furthermore, small to mid-size PA applications can be successfully achieved with an additional subwoofer for low frequency extension.

The M10 fly points and the additional mounting accessories increase its application range. The padded cover SMX 12TC protects the product during transport and storage. Finally, the daisy chain capability, the application presets and the mounting hardware allow safe permanent or non-permanent installation jobs.
