The powered mixers 453S, 458 and 459 offer a unique combination of simplicity and state of the art electronic design. Yet they do not stand out just for the professional level of equipment and high power concentrated into a minimum of space.
The structure of the small carrier cases used to contain them is a symbol which has distinguished generations of Montarbo powered mixers and is thus very popular among musicians all over the world. This distinctive metal case with covers which, when open, act as supports, was first designed and produced by Montarbo in the early 1960's with the aim of providing the working musician with the necessary tools of the trade in a small and portable package. Since then this case has 'contained' a wide range of powered mixers, each of them equipped with ever upgraded features, becoming proof of continuous technological innovation.
The digital signal processors (developed by Montarbo), incorporated in these models are just as unique as the famous magnetic memory echo effect unit of their predecessors and the ever more sophisticated electronics they contain is supported by ever more user friendly control panels.
In fact, something else is still unchanged since those early Sixties, besides the historic metal case: our construction philosophy and our commitment to guarantee the best sound quality at all times.
