Chapter 2 Delay eects 64
When the highpass lter cuto frequency value is lower than that of the lowpass cuto
frequency, only one line is shown. This line represents the frequency band that passes through
the lters—in other words, the lters act as a bandpass lter. In this conguration, the two lters
operate serially, meaning that the tap passes through one lter rst, then the other.
If the highpass lter’s cuto frequency value is above that of the lowpass lter cuto
frequency, the lter switches from serial operation to parallel operation, meaning that the
tap passes through both lters simultaneously. In this case, the space between the two cuto
frequencies represents the frequency band being rejected—in other words, the lters act as a
band-rejection lter.
Edit pan in the Tap display
The way the Pan parameter is represented in the Pan view is entirely dependent on the input
channel conguration—mono to stereo or stereo to stereo.
•
In mono input/stereo output congurations, all taps are initially panned to the center.
•
In stereo input/stereo output congurations, the Pan parameter adjusts the stereo balance,
not the position of the tap in the stereo eld.
Note: Pan is not available in mono congurations.
