User's manual System Amplifier K&F TOPAS 11. Appendix 11.1 Parametric Filters There are four parametric filters for room equalisation available in every channel The speakers are equalised in the speaker blocks (see page 33).
User's manual System Amplifier K&F TOPAS This 'bell' is logarithmically symmetrical relative to the selected frequency (in the example: 1000 Hz). The Q-factor defines the quality of the filter. In doing so, it determines the width of the frequency range which is to be increased or attenuated. The higher the Q-factor, the narrower the frequency range. A lower Q-factor thus has a wider range. "Q" is adjustable in steps of 0.001 from 0.2 to 20.
