Pioneer DEQ-P9 - Manual (Page 31)

About the H.P.F. and L.P.F.
High pass filter eliminates lower sound ranges (low-range) from the set up frequencies and
allows high ranges through.
Low pass filter eliminates upper sound ranges (high-range) from the set up frequencies and
allows low ranges through.
About the slope
This value indicates how many dB the signals attenuate when the frequency increases (or
decreases) 1 octave (unit: dB/oct.). Increasing the degree of the slope increases the degree
of signal attenuation.
Note:
• Setting the slope of H.P.F. and L.P.F. of the low-range as PASS creates a full range setup.

Using the Mute function (MUT)
It is possible to turn the Mute function ON/OFF for each band. Turning ON the Mute func-

ommended that filter adjustments be made.
