Parameters of the Stereo Spread
Order
The Order knob determines the number of frequency bands that the signal is to be
divided into.
Upper Int.
This parameter controls the intensity of the base extension of the upper frequency
bands.
Lower Int.
This parameter controls the intensity of the base extension of the lower frequency
bands.
Note that
• the stereo effect shows up mainly in the middle and higher frequencies, and
• if very low frequencies are distributed between the left and right speakers, the
energy distribution for both speakers will be significantly reduced.
Therefore, it is always best to select a lower Intensity setting for the lower frequency
bands, and to avoid setting the Lower Freq. below 300 Hz.
Upper Freq.
This sets the upper limit of the highest frequency band to be distributed in the stereo
image.
Lower Freq.
This sets the lower limit of the lowest frequency band to be distributed in the stereo
image (see the note in the Lower Int. section).
The Graphic Display
The graphic display shows the selected order (how many bands the signal is divided
into), and how strong the Stereo Spread effect will be in the upper and lower
frequency bands.
The upper section represents the left channel, the lower section the right channel, and
the frequency scale shows the frequencies in ascending order from left to right.
