Controlling Surround Equalization
Figure 8 - Surround equalization page
From the screen shown in Figure 7, press the "to LRS page" button to get to the screen shown in
Figure 8. This page allows you to control the equalization of the extracted surround channel. The
filters work just like the filters for the front channels,and you will notice a marked difference in
the sound of the extracted ambience as these filters are changed. You will likely find the the low-
pass filter is the most useful tool, giving a great deal of control over the amount of high-frequency
energy that appears in the surrounds. This characteristic gives a strong impression of the type of
acoustic space you are attempting to emulate; to emulate a highly absorptive space, you'll want to
attenuate the highs in the surrounds, whereas a very "live" space will have high frequencies coming
from the rear.
Bypassing the z-K6
The master bypass button bypasses all of the z-K6's internal processing and routes the input
stereo signal to the output. When in bypass, none of the controls can be used until master bypass
is pressed again, which returns the unit to its previous state. Bypass mode is very useful for
comparing the overall surround result to the raw two-channel feed.
Saving and Loading Presets
The entire state of the z-K6 can be saved and recalled. Press the load/save/MIDI button. This
will bring the z-K6 to the state shown in Figure 9. To save a preset, use the left knob to choose a
preset number then press the button beneath the SAVE indication. This will then bring the z-K6
to the state shown in Figure 10, which confirms that the SAVE operation took place.
