If you turn up an L1 Pro16 channel beyond 1/2 way in a quiet house and relatively no ambient noise: you will hear some noise floor because that setting is LOUD. Do the exact same thing in a club or venue and you will not hear the noise floor. Channels 1 & 2 can accommodate mic level and line level inputs, and do so by intersecting hardware/preamp gain and digital/DSP gain. While no signal is present, you may hear the DSP gain "steps" while increasing or decreasing the volume. But when an audio source is connected, the user hears a smooth, continuous volume taper. This is what matters to the user and to the audience.
