filters. Care must be given configuring these filter bands, as they interact and can produce unexpected
results. Using the DSP 260 Editor PC application is strongly recommended to set all but the most simple
eq curves.
Each band of the Input PEQ can be configured for a specific filter mode, frequency, slope or Q and gain
setting. Attention must be paid to the ultimate output gain through the rest of the DSP 260’s audio path, as
it is possible to boost frequency ranges to the point where the internal or external audio paths of the
system may be clipped. Monitoring the output VU meters of the DSP 260’s output channels will indicate
internal clipping; the input meters of connected amplifiers should do the same.
To bypass any band of the DSP 260’s Input PEQ multi-mode filter
bank, set the desired band’s gain to 0.0 dB. This will have the effect
of bypassing the selected filter band.
The following section details the type of filters that can be selected
for each of the Input PEQ’s 9 bands and their parameters:
Low-shelf
The Low-shelf filter is a “hinge” type; in that frequencies below its frequency setting can be
boosted or cut; hinging on the cut-off Frequency. The amount of boost or cut (Gain), and
the extent of width of the filter’s transition band (Slope), are determined by the low-shelf filter’s settings.
(See Response/Q and Gain.)
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.)
Hi-shelf
The Hi-shelf filter is a “hinge” type; in that frequencies above its frequency setting can be
boosted or cut; hinging on the cut-off Frequency. The amount of boost or cut (Gain), and
the width of the filter’s transition band (Slope), are determined by the hi-shelf filter’s settings. (See
Response/Q and Gain.)
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
unit, or press and hold to scroll rapidly through available values. (Values do not wrap-around.)
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-
