Low -pass
The Low-Pass filter determines the ultimate
high frequency that your sound reinforcement
system is allowed to reproduce; given the
capabilities of amplifiers, speakers and transducers. The low-pass filter
is useful for reducing excessive high frequency energy that can create
stress on high frequency transducers and listener fatigue.
Available parameters are Frequency and Slope. The frequency
parameter determines the frequency above which frequencies will be
attenuated. The slope determines how quickly frequencies above the
cut-off frequency will be attenuated. (See response curve.)
Use the < Select > buttons to navigate to the filter setting you wish to
adjust, and the Value Up and Down buttons to alter these settings.
Press the Value Up and Down buttons once to increment values by one
unit, or press and hold to scroll rapidly through available values. (Values
do not wrap-around.)

PEQ
PEQ is shorthand for Parametric Equalizer. A
parametric equalizer has three parameters that
determine the frequencies that are affected by it;
Center Frequency, Q (filter-width) and Gain.
Parametric filters are ideal for identifying, isolating
and correcting problematic frequency ranges.
The Frequency parameter determines the center of a range of
frequencies that will be adjusted by the PEQ. The Q parameter will
determine the range of frequencies adjacent to the center frequency
that will also be effected; the greater the value, the smaller the range of
adjacent frequencies that will be effected. The gain parameter
determines the amount of boost or cut that is applied to the frequencies
that are affected by the filter.
Use the < Select > buttons to navigate to the filter setting you wish to
adjust, and the Value Up and Down buttons to alter these settings.
Press the Value Up and Down buttons once to increment values by one
