The gain for microphone pre-amp and auxiliary input (IN3L/IN3R) signals can be independently
adjusted for each output mixer. This does not affect the volume of the same signals going into the
separate record mixer. The level of the DAC output signals can be adjusted using the DAC’s digital
volume control function (see Table 32).
