There are a lot of audio processors in life. What are the basic contents for audio processors? Do you understand the digital processor output function?
Signal input distribution routing (ROUNT): The function is to let this output channel choose which input channel to accept the signal, generally can choose A (1) input, B (2) input or mixed input (A + B or mix Mono), if you choose A,
Then the signal of this channel comes from input A, and does not accept the signal of input B. If A+B is selected, then there will be a signal coming in this channel regardless of which signal is present in A or B.
High-pass filter (HPF): This is the lower limit of the frequency used to adjust the output signal. It is like adjusting the lower crossover point of the speaker. The internal is usually composed of three parameters, one is the frequency, which is used to select the desired lower frequency limit. The other is the filter form, there are generally three kinds, LR, BESSAL, butworth, if you don't understand, you can choose LR, the third parameter is the filter slope, generally 6,12,18,24,48dB/ OCT is a few, too deep, I have not said a few, this slope means that the larger the value you choose, the cleaner the score.
Low Pass Filter (LPF): It is used to adjust the upper frequency limit of the output signal, just like controlling the upper crossover point of the subwoofer. The internal adjustment content is the same as HPF.
The combination of HPF and LPF is a bandpass filter, like an external 3-way speaker. The crossover point is 500/3000 Hz, then the LPF of the bass channel is 500, the HPF of the midrange is 500, and the LPF is 3000. The HPF of the high-pitched channel is 3000, the filter format is LR, and the crossover slope is 24, which is generally correct.
In addition, some processors combine the filter form and the crossover slope as options.
Output equalization is generally the same as input equalization, except that general output equalization is only parametric equalization, and there is no option for equalization.
The output polarity adjustment is the same as the input section. It is used to convert the polarity of the output signal. Some processors also have a phase angle (PHASE) adjustment at the output. This is a bit deep, I will not say a few words.
Output a true limiter: generally there are 3 parameters adjustable, which is the start level, start time and recovery time. The adjustment of the startup level is based on the characteristics of the amplifier and the speaker. Generally, under normal circumstances, the control does not allow the amplifier to emit a red light. The startup time and recovery time are selected according to the frequency, the low frequency is slowly recovered with a slow start, and the high frequency is quickly recovered with a fast start. , the middle frequency is in the middle.
