The DMM4/2/2 is a high-performance digital automatic mixer with four balanced microphone inputs, two AUX inputs and one mono master output. The mixer offers an intelligent mixing algorithm for seamless mixing including a ducking function. Each input channel features low-cut, LF and HF shelving filters, a dbx® compressor/limiter, switchable input gain (Mic/Line, Mic-Lo/Mic-Hi), switchable phantom power and an incremental level control with LED level and peak hold display. 

Multiple DMM4/2/2 mixers can be daisy-chained for larger systems. A rear-panel control I/O port provides logic inputs and outputs for controlling external devices.
