The CF-P20A is a car power source is composed of a generator and a battery (accumulator). The car is powered by the battery when it is not started. However, its primary design purpose is to start the engine. Therefore, it is possible to instantaneously supply a large current, but the voltage It will also instantly drop to 2-4V, which is why many car audio systems suddenly ” lose sound ” when the car starts.
After the generator to start working, the generator usually stabilizes the output of about 13.8V. Many DSP amplifiers that use dedicated wire harnesses do not have a boost circuit inside, so the maximum possible power output is only about 47 W (4 Ω load).This is why many DSP processors have features, but the effect is not particularly noticeable.
According to the general speaker sensitivity of 90dB (has been considered very high) to calculate, its maximum output dynamics can only reach about 105dB, which is far from the current high-definition music, etc. far beyond the 110-120dB large dynamic output.
This is why many DSP have all the features, but the effect is not particularly noticeable.
Crossfire launched the CF-P20A, which is a power management unit from the electronic circuit. Its biggest role should be the power stabilizer, and because there is a boost circuit inside, the CF-P20A can output 17.1V stably ( +/- 0.1V) power output.
