speaker "bottoming out" - harsh pops or cracking distortion that indicate that the speaker voice coil or
diaphragm is striking the magnet assembly.

Martin Audio recommends that you use amplifiers of this power range for more headroom (cleaner sound)
rather than for increased volume.

Speaker output shock hazard

A Martin Audio amplifier is capable of producing hazardous output voltages. To avoid electrical shock, do not
touch any exposed speaker wiring while the amplifier is operating.

This manual contains important information on operating your Martin Audio amplifier correctly and
safety. Please read it carefully before operating your amplifier. If you have any questions, contact
your Martin Audio dealer.
