Stereo powered mixer

A case making history: Montarbo 459S powered mixer isn’t just compact and powerful: it’s the evolution of an original concept developed more than fifty years ago, the contemporary version of many generations of Montarbo's powered mixers.

Its metal case became iconic amongst musicians over the sixties, and the open lids embedded in the enclosure still double as a mixer stand the mixer, jus like in the original model.

Under the bonnet you can feel the technology behind 459S:a multi-effects 56bit DSP, advanced protection circuits on the amps, plenty of horse power to drive your PA.

The mixer shows 8 mono inputs, and the power outputs of the on-board AB-class power amplifier are able to provide up to 320W for each of the 2 channels.
