Figure 3 - threshold/ratio screen
Press the threshold/ratio screen select button. The display will appear as in Figure 3. Use the
channel select knob
to move the arrow to the desired channel. The parameter #1 knob controls
the threshold and the parameter #2 knob controls the compression ratio. The threshold is
calibrated in decibels relative to full-scale digital (dBFS) and the compression ratio is to be
determined as the number of decibels the input level must rise above the threshold in order to
produce a one-decibel increase in output level. The gain reduction meters will continue to
function when the z-CL6 is in threshold/ratio mode, as will the individual channel bypass buttons.
The threshold ranges from 0.0 dB to -95 dB. The ratio can be made to vary from 1.1:1 to 8.0:1.
Turning the ratio knob one click past 8.0:1 turns the compressor for that particular channel into a
limiter, with a ratio of 100:1.

Figure 4 - hipass/make-up gain screen
Press the hipass/make-up button. The display will appear as in Figure 4. Use the channel select
knob
to move the arrow to the desired channel. The parameter #1 knob controls the corner
frequency of the hipass filter (explained below) and the parameter #2 knob controls the
compressor make-up gain. The make-up gain is calibrated in decibels relative to full-scale digital
(dBFS). The gain reduction meters will continue to function when the z-CL6 is in hipass/make-
up gain threshold/ratio mode, as will the individual channel bypass buttons.
