Limiter LED Adjustment
The limiter LED in not affected by the limiter threshold adjustment.
However to change its turn on point the procedure above may be used.
The turn on point is normally 2-3 dB higher than the limiter threshold so that it’s not too sensitive to peaks of
short duration.
The trimmer (RP2) is on board A (see layouts). An extender board is available, however access is also possible by
removing 1 or 2 input modules.
Clockwise = lower turn on point.
