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!
