Introduction:
Balanced output, undistorted level output efficiency is 180% of traditional power
In conjunction with Class A circuits, the three band timbre is presented to the fullest.
The balance signal is composed of: (1, GND O) (2, cold end) (3, hot end)
To form a balanced superimposed cross signal, a specialized balanced power amplifier is required to amplify it,
At the same time, it is also necessary to have a very close amplification coefficient between the cold and hot ends,
This has extremely high requirements for component pairing and amplification,
So, the price of a balanced amplifier is generally about four times higher than that of a traditional amplifier
Some power amplifiers, although equipped with balanced inputs, actually use a balanced signal converter to achieve compatibility with balanced signals.
Although this type of amplifier has some improvement in sound quality, it still lags far behind true balanced amplifiers.
