ECHNOLOGY

 

MMATS Professional Audio is the industry leader in ultra-efficient 
Class D audio technology for 12 volt audio. 
 
Your D600.2 amplifier is engineered using the best technology we 
have at MMATS.  
 
 

Surface mount technology 

 

Large geometry power MOSFETs 

 

Leading edge pulse width modulation design 

 
D600.2 amplifiers are the perfect match for producing bass from 
large speakers in an automotive environment. Since most of the 
acoustic energy needed to produce full range audio is in the bass 
frequencies, it makes sense to dedicate your system’s most 
powerful amplifiers to this task. Also, an automobile has a limited 
amount of energy available in its charging system to produce these 
power hungry bass frequencies. Therefore, an efficient amplifier that 
doesn’t waste energy as heat would be desirable. 
 
Class D amplifiers are switching amps. Instead of producing power 
continuously like a traditional Class A or AB amplifier, a Class D 
amplifier switches on and off thousands of times a second and 
doesn’t waste energy (as heat) by being on when not needed. 
 
Comparison of technologies at full power: 
Class AB 500W amp at 50% efficiency will draw 1000W off the 
charging system. 
1000W / 12.5V = 80 Amp draw 
 
MMATS Class D 500W amp at 72% efficiency will draw 694W off 
the charging system. 
694W / 12.5V = 56 Amp draw 
 
1000W - 694W = 306W wasted as heat that should be driving 
your speakers!
