Gain crossover frequency is the frequency at which a system's magnitude is equal to unity, or 1.
at low frequency less than 50hz the voltage gain decreases with decreasing frequency and at mid frequency{50hz to 20khz} the voltage gain is uniform because resistor value are independent of frequency change and at the high frequency votage gain falls.
unity-gain frequency
A: As frequency increases all amplifier exhibits losses due to internal capacity or internal devices frequency limit. At the hi end of the frequency the amplifiers begins to loose gain gradually as a function of higher frequency that is what roll off is.
The transition frequency of a transistor is the frequency in which the transistor will no longer provide any amplification or gain output. The frequency is out of the transistors's range.
The gain of an r-c coupled amplifier falls at high frequency because the capacitive reactance of the capacitor tends to zero.
Gain crossover frequency is the frequency at which a system's magnitude is equal to unity, or 1.
First find the phase crossover frequency and then use that back into the magnitude of the transfer function.Then the gain margin is the reciprocal of that magnitude.
Using a crossover, you can limit the frequency response of the signal sent to speakers.
When you say car audio crossover gain do you mean the gain on one of your amps or the decible gain you can adjust through your head unit?
False
low frequency gain will be 20log(Vo/Vin)
at low frequency less than 50hz the voltage gain decreases with decreasing frequency and at mid frequency{50hz to 20khz} the voltage gain is uniform because resistor value are independent of frequency change and at the high frequency votage gain falls.
Because Beta (current gain) in a transistor is inversely proportional to frequency. Hence it increases as frequency decreases. Also the ac voltage gain is directly proportional to Beta.

All of the Pioneer Amps feature adjustable "Gain" which will allow you to boost the output. Additionally, any of the Pioneer Subwoofer Amps feature a crossover which lets you choose how much bass frequency you want to drive.
