The wordwidth for each channel group can be controlled independently. There are six settings for
each wordwidth:
24 bits dithered
24 bits undithered
20 bits dithered
20 bits undithered
16 bits dithered
16 bits undithered
16 bits POW-r #2
16 bits POW-r #3
The dither used is a variant of flat TPDF dither, while POW-r #2 and #3 are noise shaping curves.
Press any of the other mode select buttons to exit from the wordwidth rate mode.

One of the z-CL6's most powerful features is its ability to link the level detection and compression
action across multiple channels. At first, it may seem slightly awkward to control the linking but
we are confident you will quickly find the controls to be intuitive and easy to use.
There are four channel groups on the z-CL6: the fronts, the surrounds, the center, and the
subwoofer. Each of these groups is endowed with two controls: a mix control and an out control.
The purpose of these controls is to allow you to vary the amount of interaction each of the
channel groups has with the other groups.
Internally, the z-CL6 generates four "sums of levels" They are:
Sum
LRF
= outlevel(LRS) + outlevel(CEN) + outlevel(SUB)
Sum
LRS
= outlevel(LRF) + outlevel(CEN) + outlevel(SUB)
Sum
CEN
= outlevel(LRF) + outlevel(LRS) + outlevel(SUB)
Sum
SUB
= outlevel(LRF) + outlevel(LRS) + outlevel(CEN)
Notice that each of these sums is simply the sums of three of the four group levels with one of the
groups omitted.
The value of "outlevel" for a channel group is nothing more than the group's actual level
multiplied by the percentage indicated by the out parameter for that group.
