Switching To The Filter Adjustment Mode; Using The Mute Function - Pioneer DEQ-P90 Owner's Manual

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.

Before making filter adjustments
• When the position is set up for the driver's seat after adjusting the distance between the listening
position and each speaker of the Time Alignment Adjustment function (refer to page 25), it is rec-
ommended that filter adjustments be made.
• Store the different filter characteristics into memory, by the listening position set up with the
Position Selector function (refer to page 13) or by the source being listened, and switch when nec-
essary. Refer to page 34 for memory operations.
