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 amplification (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 of parametric EQs.
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.
PRIORITY MATRIX
The Priority Matrix DSP block is an extended Matrix Mixer. Clicking with the left mouse button onto the
node in the matrix where the output channel's column and the input channel's line meet, connects an output to an
input. Again clicking onto the node separates the connection. Right clicking on a node allows editing the level. When
connecting the device to a PROMATRIX/PROANNOUNCE System, allows dynamically setting nodes in the Priority Matrix
from call stations. Please also refer to the notes in chapters RS-232 Setup and Macros.
Next to connecting inputs and outputs, assigning Priorities to input channels is possible as well. The Priority Matrix
provides the following features:
– Exactly 256 Priorities exist, numbered from 0 up to 255.
– 1 represents the lowest priority and 255 is the highest priority.
– If various input signals with different priorities are assigned to a single output at the same time, only the signal
with the highest priority is connected through to the output.
– If input signals with equal priority are assigned to a single output at the same time, a mixed signal of these input
signals is output.
– An input signal with priority 0 assigned to an output gets connected through to the output in any case. If another
signal (with another priority) is present at the output, it is mixed with the signal that has priority 0.

0.04...2.8 Q or BW defines the quality or bandwidth of a parametric EQ. A high
6 Oct. Q-value results in a narrowband filter, while a small Q-value results in
or 0.4...40 a broadband filter. The Q-value also sets the quality and thus the
response of Hi, Lo and All pass filters with slopes of 12dB/oct.
6dB/Oct, SLOPE sets the steepness or filter-order of low or high shelving
12dB/ equalizers and low or high pass filters. Setting different slopes within
Oct the transmission range is possible. That, in conjunction with the Q-
parameter, offers the possibility for a hi-pass filter to be programmed
for B6- alignment, which describes a drastic rise in the cut-off
frequency range.
BYPASS switches the corresponding filter ON (not engaged) or OFF
(engaged), which allows for quick A / B-evaluation of the actual effect
that a filter has on the sound.
