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
