Xover Filters
Xover Filters is used in 004: St.Multiband Compressor,
015: Stereo Isolator, and 086: Multiband Mod. Delay.
Crossover point between band 3 and band 4
Crossover point between band 2 and band 3
Crossover point between band 1 and band 1
Limiter
Limiter is used in 005: Stereo Limiter, and in "Limiter"
of Mono-Mono Serial and Mono//Mono Parallel
effects #121 and following.
This is a realtime indication of whether the control
input signal level is Under the threshold level or Over it.

The red line indicates the specified crossover point.
Band1 Band2 Band3 Band4
This is a conceptual diagram of each
band's frequency response.
(It is not the actual response.)
Vertical axis: Gain (dB)
Horizontal axis: Cutoff frequency (Hz)
This is a conceptual diagram of the slope.
(It is not the actual response.)
This is a realtime indication of the gain adjustment level
relative to the input signal. (Level changes in the opposite
direction indicate negative values.)
This is a realtime indication of the output signal level.
Indicates the output response relative to the input. This will
change according to the Ratio and Threshold settings.
Input below the Threshold will be output "as-is" without being
compressed. In the example shown here, a –40 dB input will
be output at –40 dB.
Input above the Threshold will be compressed for output. In the
example shown here, a –10 dB input will be output at –20 dB.
The actual compression ratio also depends on the Attack and
Release settings.
Threshold level indication
Vertical axis: Output signal (the output from the limiter
circuit)
Horizontal axis: Input signal (the input to the Envelope-
Control circuit)
This is a realtime indication of the control input signal level
(after passing through the Side Chain EQ)
