Conformal Coating
The internal components of APM amplfiers have been coated with a marine grade
protective coating that shield them from the elements. This asures optimal performance
in even the most rigourous enviroments. Although the amplifier is protected agaist the
elements , it does not make the amplfier 100% water resistant. Special care must be
taken when chosing a mounting location to asure that it does not end sumerged under
water.
Bass Boost
For added low frequency performance the amplifiers are equipped with a variable 0dB-12dB
bass boost @ 45Hz
Power Fusing
Due to the smaller foot print of the amplifier, external fusing is required.
Variable Crossover
The "APM Marine" amplifiers include built-in variable crossovers. The APM 250.4D offers
an independent 12dB per octave High Pass and Low Pass X-Over on channels 1&2 and
a Selectable 12dB or 24dB per octave X-over on channels 3&4. The APM 300.2 offers a
12dB per octave slope when set to either Low or high pass settings.
