** Set Martin Audio MA4.2 rear MLS switch to 0dB to match peak output of
unregulated power amplifiers.
Use lower settings (or more subwoofers!) if your power amplifiers indicate clipping
on more than just the odd peak. Excessive clipping may also be caused by inadequate
power amplifier reserve or an inadequate mains supply.
