Control Elements
10 Stereo Width
With the STEREO WIDTH control, you can increase or attenuate the level of the side signal
by 5.5dB. This way, you can change the perception of the stereo width.
11 Elliptical Filter
The ELLIPTICAL FILTER (Cauer Filter) removes signal components below a predefined fre-
quency from the side signal. You can then hear these signal component through the M/S
decoding in the mid signal component. The ELLIPTICAL FILTER has an extremely steep
slope. The cut-off frequency can be adjusted from 22Hz up to 450Hz.
