The correct choice of amplifier, its settings, filtering and enclosure largely influence on the lifespan of your audio system. You
should select an amplifier with a nominal power, not exceeding the nominal power of the speakers. Proper coordination of the
head unit (HU) with the amplifier will allow to get clean, undistorted signal applied to the component to prevent overheating and
voice coil damage. Recommended settings of the amplifier and HU: Volume of HU should not exceed 80%. The amplifier
sensitivity should be set to 50%.
The recommended filter settings:
The high pass filter HPF (the filter that cuts all frequencies below those set for the filter) should be set to 60-80 Hz
(12 dB/Oct) for mid-bass speaker and should be set to 6-8 kHz (12 dB/Oct) for tweeter.
Recommended amplifiers: MLA-60.2, MLA-100.2, MLA-160.2, MLA-60.4, MLA-100.4, MLA-160.4.
CAUTION!!! High sound pressure can damage your health!
Please use the common sense when controlling volume!
MLC-60: HPF (mid-bass) - 60-80 Hz (12 dB/Oct)
HPF (tweeter) - 6-8 kHz (12 dB/Oct)
