Equalization
The XTi2 Series provides two blocks of equalization in the signal processing. The input EQ block is before the crossover and
is usually used for the room EQ. The output EQ block is after the crossover and is usually used for speaking tuning.
Input EQ: This input EQ block provides 6 filters per channel each with frequency, gain, and Q that is user controllable.
This block also has a High and Low Shelf Filter per channel which has gain and frequency control.
Output EQ: This output EQ block provides 8 filters per channel each with frequency, gain, and Q control that is user
controllable.
Håper dette var til litt hjelp
