The Input/Output meter indicates the input signal and the ReVibe output. The range of this meter is from 0 dB to –60 dB. The number of input/output meters that operate simultaneously ranges from a single meter for mono input and output, up to five input/output meters for 5.0 and 5.1 multichannel processing. The meters that operate depend on the channel format of the track on which the plug-in is inserted.A red channel clip indicator appears at the top of each meter, and an internal clip meter appears above the meter display itself. The clip indicator lights when the signal level exceeds 0 dB, and stays lit until the user clears it. Clicking a meter’s clip indicator will clear that meter.It is possible to clip internally even when input levels are relatively low. This can occur because a digital reverb is essentially a series of filters and delays. Feedback within the signal paths can cause buildup of the reverb signal, which can cause the level to increase and overload (similar to a delay line with a high level of feedback).
