Description of operation:
The Center Freq text box / slider controls allow the user to
either type in the desired Center Frequency of each stage
directly, or to make manual adjustments. Click on the
left/right arrow button at either end of the slider to make fine
adjustments to center frequency, or drag the scroll box to
make coarse adjustments. Center Frequency can be
specified in 1 Hz steps.
The
Width text box / slider controls work similarly to the
Center Freq controls. The displayed Width, however, is
proportional to the Center Frequency, and will thus be
automatically changed whenever the Center Freq controls are
adjusted.
The
Boost/Cut controls work similarly to the Center Freq and
Width controls, as the Boost/Cut can be typed directly or
selected with the slider control. The Boost/Cut adjustment
ranges from -60dB to +16dB in 1dB increments.
Warning: Pay particular attention to the Output
Level and Stage Overload indicators when positive
Boost/Cut values are used, as the maximum digital
signal range of the PCAP can easily be exceeded.
The
Substage In/Out buttons allow the user to quickly
bypass ( Substage Out ) any stage.
