CLASS D TECHNOLOGY

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!
