  EQ – Q

 

  The Q factor controls the bandwidth that will be 
  boosted by the equaliser. The lower the Q factor, 
  the wider the bandwidth. The higher the Q factor, 
  the narrower the bandwidth.

 

EQ Gain

 

  EQ Gain increase or decrease the gain 
  at selected frequency.

  Filter Type

 Frequency

 

  This is a user input field for the centre point in 
  the crossover frequency bandwidth applied.

  Filter Order
