General digital processor usage
General digital processor, the internal structure of common parts by the input and output components, which are part of the function of the general audio processing as follows: the input part of the general will include, input gain control (INPUT GAIN), enter the balance (balance of a number of segment parameters ) adjustment (INPUT EQ), the input delay adjustment (INPUT DELAY), the input polarity (that is, we say that phase) into (inputpolarity) and other functions. The output of some of the general distribution of routing a signal input (ROUNT), high-pass filter (HPF), low-pass filter (LPF), equalizer (OUTPUT EQ), polarity (polarity), the gain (GAIN), limiting startup level (LIMIT) such number of common features.

Here are some general digital processor part of the main features of each function:

    
Input Gain: This surely we all know, is to control the processor's input level. General can be adjusted within the range of 12 dB or so. Enter the balance: the majority of the general use of digital processors, 4-8 full-parametric equalizer, 3 internal adjustable parameters, namely, frequency, bandwidth, or Q value, gain. Adjusting the first and third two parameters we are generally aware, more confusing is the bandwidth (or Q value), this I do not want to say, just tell us a basic concept: bandwidth, said with OCT, OCT = 0.35, adjustment range, adjust the balance of the same effect and 31, OCT = 0.7, adjust the scope and effect and about 15 band equalizer, OCT = 1, adjust the scope of paragraph 7 equalizer effects and about the same. OCT larger the value, the wider the range that you adjust. The Q value, it can be understood as the inverse of OCT, OCT = 0.35 is the corresponding Q value of about Q = 3, we can look at their conversion. During regulation time, if you do not understand, put this bandwidth value is set to around 0.3 (or Q = 3), and then select the desired tone frequency, so that you can adjust in accordance with paragraph 31 of law and the sense of balance to tune the gain of the.

   
There are some digital processor such as DBX, General equilibrium in the parametric equalizer (parameter EQ) and the graphic equalizer (graphics EQ) convert each other, the use of any type, mainly to see your personal operating habits.

    
Input Delay: This feature is to allow the input signal processor sets a time delay into the conduct of some of the general on this processor and it controls the speaker as a supplement to do the whole time delay adjustment.

    
Input polarity: you can make entire processor to switch between positive and negative polarity phase, and to cut you change the line.

    
These are the input part of the briefing, said the following about the output section.

    
Signal input distribution routing (ROUNT): is to make the choice to accept the output channel over which the signal input channel, can generally choose A (1) input, B (2) input or mixed input (A + B or a mix mono), if you choose A, then the channel's signal from the input A, B, do not accept the input signal, if you choose A + B, then A or B no matter which way a signal, the channel will have the signal come.

    
High-pass filter (HPF): This is used to adjust the output signal frequency limit, such as adjusting the next speaker crossover, the internal parameters are generally formed by the three, one frequency, used to select the frequency limits Another form of the filter, generally 3, LR, BESSAL, butworth, if you do not understand, select the LR can, and the third parameter is the filter slope, generally 6,12,18,24,48 dB / OCT few, too deep I will not say, and this means the slope the greater the value of your choice, point the more clean.

    
Low-pass filter (LPF): is used to adjust the output signal frequency upper limit, such as control on the subwoofer crossover point, the internal regulation as content and HPF.


  
HPF and LPF together is the band-pass filter, such as an external 3-way speaker, crossover frequency is 500/3000 MHz, then the bass on the election channel 500 LPF, HPF Alto channel selection 500,

LPF election 3000, election 3000 treble channel HPF, the filter in the form elected LR, Crossover Slope selection 24, are generally right.

    
In addition, some processor is to filter the slope of the form and frequency together as an option.

    
Balanced input balanced output and the same general gameplay, but normally only the output parameters of a balanced equilibrium, and no graphic equalizer option.

    
Enter the part of the adjustment and output polarity as the polarity of the output signal for the conversion, there are some processors in the output phase angle (PHASE) regulation, this a bit deeper, I will not say more.

    
Output limiter: generally have three adjustable parameters, that is, start level, start-up time and recovery time. Start level adjustment based on the characteristics of amplifier and speaker, usually in the normal circumstances, not out of control so that the red light amplifier, start time and recovery time, depending on frequency selection, low frequency slow start and fast recovery, high-frequency slow start with fast recovery IF center.

    
Processors generally have several regulatory options, one is similar to the DBX, the options button in the panel, according to different functions, into a different set menu, and then use the arrow keys to adjust the parameters chosen, then adjust the data using the parameter wheels. There is a similar XTA, and pressing the edit button in each channel, into the channel editing interface, and then select the number of function keys

Functions and parameters to adjust.
