Processing Available on Every Channel: All 20 input and 20 software playback channels can independently host 3-band parametric EQ, High-Pass Filter, compressor, expander, auto-gain, and reverb/delay sends.
-
Flexible Routing Matrix: Provides powerful routing capabilities, allowing the creation of multiple independent monitoring mixes (e.g., musician headphone mixes, control room monitoring), and freely routing any input to any output.
-
Software Control and Scene Storage: All operations are performed via an intuitive software interface, and complete mixing scenes can be saved, facilitating quick switching between different projects or performances.
DURec: Direct USB Recording Function
