Filter Editing via "Mouse Movement" in the Graphics Display
A white dot in the frequency response display represents an active filter (BYPASS not engaged). Clicking with the left
mouse button on this dot and keeping the mouse button pressed down allows changing the selected filter's frequency
by moving the mouse to the left or to the right as well as its gain or cut (depending on the selected filter type) by
moving the mouse up or down. Clicking with the right mouse button on the white dot and keeping the mouse button
pressed down allows changing the Q-values. For an improved overview the name of the corresponding filter band
appears in color as soon as the mouse cursor is positioned over its white dot. An additional white graph indicates the
frequency response of the actually selected filter.
ARRAY DELAY
Individual array delays can be set for each output channel of the power amplifier.
HINT: The Array Delay parameter can be used for adjusting the individual cabinets within a loudspeaker cluster,
such as a subwoofer array or a center loudspeaker cluster. For example, in a speaker cluster consisting of two horn-
loaded loudspeakers, it is helpful to apply 3-5 ms of delay to one of the loudspeakers in the cluster to improve the
coverage in the overlap of the horn patterns. Additionally, the array delay provides a convenient section to apply
dedicated delay to individual subwoofer cabinets to create gradient or beam-formed arrays.
Bosch Security Systems B.V.
20 Hz to 20 kHz FREQ (frequency) sets the center frequency of a parametric EQ or the cut-
off frequency of shelving and Hi / Lo pass filters.
0.4 to 40.0 Q defines the quality or bandwidth of a parametric EQ. A high Q-value
(PEQ), 0.4 to results in a narrowband filter, while a small Q-value results in a broadband
2.0 filter. The Q-value also sets the quality and thus the response of Hi, Lo and
(Hi-/Lo-/ All pass filters with slopes of 12dB/oct..
Allpass)
-18 to +12 dB GAIN defines the amplification (increase) or attenuation (reduction) of
parametric EQs or low shelving and high shelving equalizers.
first, second ORDER (only available with Allpass filters) sets the desired filter order of
an All pass filter. A 1st order All pass filter rotates the phase by 180°, a 2nd
order All pass filter rotates the phase by 360°.
The caption of this button indicates the current state of the filter. Press the
ACTIVE button to deactivate the filter (Bypass), which allows for quick A /
B-evaluation of the actual effect that a filter has on the sound.
Press the EQ FLAT button to reset all filters to type PEQ with 0 dB.
