Main Features

Fader bank section and assignable fader section
The fader bank section, where 8 faders are provided, can also be used as independent sets of 8 faders or as interlinked sets of 16 or 24 faders. The
decision on how to use the 24 controls can be made instantly, letting you operate the M-5000 and its huge mixing engine with optimal efficiency. You
can also assign often-used input channels and output buses to the four assignable faders and display them on the top panel at all times.
Organic EL displays offering excellent brightness and visibility are provided above both the fader bank section and the assignable fader section,
enabling quick confirmation of information.

User-assignable section
Assigning frequently used functions to the user-assignable section lets you display important functions on the top panel at all times. This groups
together four encoders and eight buttons in a compact layout, but you can assign many more functions to this section by switching between three
banks.
