Digital amplifiers amplify the signal differently and there is pro’s and cons to that.
The con is that they introduce noise and interference especially higher up the frequency chain, although there are now full range digital or hybrid amps that seem to be alleviating some of these problems. .
Because of the way they amplify the sound they are much more efficient up to 85 – 90% efficient, compared to 45-55% efficient like say a class A-B (most normal amps)
Because they are more efficient, they can be much smaller and also get less hot.
So i guess if it is rtwice as efficient (which many are) then from the same size package you can get twice the output. |
