Descrizione

The DM-4800 is the latest member of Tascam’s DM digital mixer series. With 64 mixing channels, 24 busses and 12 auxes it is currently one of the most powerful portable digital consoles at all. At the same time, it offers lots of convenience: The so-called full-channel section, for instance, allows all channel parameters like dynamics, EQ settings, aux levels and panning to be manipulated with dedicated controls. 24 motorised channel faders and 24 rotary encoders with ring LED indicators additionally give access to virtually any module setting available.

With its comprehensive feature set, multiple routing and expansion capabilities and its ease of use, the DM-4800 is the ideal mixing console for any modern recording studio as well as for live mixing and recording applications.
