Why Digital Amplifier?
The main issue is ‘EFFICIENCY’!
Efficiency in amplifier is watt’s ratio to be supplied to achieve the expected output from the amplifier.
For example, a 92% efficient amplifier requires about 1300W to be supplied to achieve 1200W
output. On the other hand, 50% efficient analog amplifier requires 2400W power.
Thus, the existing analog amplifier requires more power to achieve the same amount of outputs.
Also, it will extremely generate heat because high power losses due to low efficiency.
DPA-SERIES digital amplifier is high efficient,
low heat-dissipating and eco-friendly amplifier which minimize power consumption and
generation of heat by designing as the maximum 94% high efficient SMPS power and the maximum
92% efficient Class-D amplifier.
