For the first simple test, we checked that the power up, the peak indicators ("Clip" on the micro/line inputs) on the Audiodock and the red zone of the VU meters really represented the effective maximum sound without distortion. That was indeed the case for the hardware indicators on the Audiodock, but the VU meters in the tracks did not perform as well: the red light came on without the trace of a peak. This means that there is a safety margin, which is something good to know.
