lters no.1 (‘high-pass’) and no.6 (‘low-pass’).
EQUALIZER
Click EDIT to open the EQ setting window (of its respective audio input).
EQUALIZER

18
ENGLISH
Slope: lter slope setting (dB / oct).
Q: Q factor setting.
Gain (dB): lter gain setting.
Freq (Hz): either lter frequency selection or PEQ central frequency setting.
File Commands:
- SAVE: it saves to PC the current equalization as .rde le.
- LOAD: it loads from PC an equalization previously saved as .rde le.
Eq. options:
- FLATTEN: it disables all lters (at frequency response).
- BYPASS EQ.: it disables the equalization, but without changing lter settings.
- PHASE PLOT: if selected, the phase plot is shown (green line).
Devices commands:
- STORE: it sends and stores the equalization to MZ 8060.
- SEND: it sends (without storing) the equalization to MZ 8060.
For each lter, frequency and gain can be adjusted either graphically (through the mouse)
by dragging the little coloured square or in an analytical way (by inserting the values in
the cells or rotating the control).
The overall equalization is shown as a red line, the intervention of the selected lter as a
green line, the intervention of a lter that is not selected as a white line.
For example, to apply a 12 dB attenuation for frequencies below 80 Hz: enable the lter
1 by clicking its ‘Enabled’ checkbox, select the SHELVING LOW lter type, set the gain to
–12 dB and frequency to 80 Hz.

19
ENGLISH
To add a second lter (i.e. PEQ): enable the lter 2, select the PEQ lter type, its gain and
central frequency, then set its Q factor.
Finally, click either STORE (send and store) or SEND (send without storing) all EQ settings
to MZ 8060.
COMPRESSOR
The compressor does not modify a signal having a level lower than the predetermined
threshold and compresses a signal with higher level.
To access its parameters (of a single input), click EDIT on the respective channel and
select the DSP window.
THRESHOLD and RATIO values can be adjusted either by moving the respective faders or
dragging (with the mouse) the red points in the graph.
THRESHOLD: adjusts the level above which the compressor compresses the signal.
OUT GAIN: adjusts the output gain (useful to minimize the signal attenuation due to
compression).
Attack: adjusts the compressor attack time.
Release: adjusts the compressor release time.
Ratio: sets the ratio between the original signal (above the threshold) and the
compressor output.
For example: if ratio is 2:1, a signal that exceeds the threshold of 2 dB will be compressed
to 1 dB (above the threshold).
Indicatively: 2:1 ratio is suitable for voice, from 2:1 to 4:1 for musical instruments.
A compressor having a ratio higher than 10:1 operates as a limiter.
A 1:1 ratio is an invalid setting, as it does not compress at all.
Enable: toggles the compressor (keep it on when using).
COMPRESSOR

20
ENGLISH
USE EXAMPLE:
1. Set THRESHOLD to a level lower than 0 dB (e.g. –15 dB).
2. Set RATIO (i.e. 4:1).
3. Adjust OUT GAIN in order to increase the signal output gain (to minimize the
compressor attenuation, i.e. +10 dB).
123
AUTOMATIC GAIN CONTROL (AGC)
The automatic gain control does not modify a signal having a level lower than the
predetermined threshold, but increases or reduces a signal above the threshold to get
the desired average level (‘target’), within the set time and according to the compression/
expansion ratio.
To access AGC parameters (of a single input), click EDIT on the respective channel and
select the DSP window.
THRESHOLD: adjusts the level above which the AGC operates.
TARGET: adjusts the optimal average signal level to be obtained.
Time: adjusts the AGC intervention time.
Ratio: sets the ratio between the original signal (above the threshold) and the AGC
output.
Use a ratio in the 1.5 ÷ 3 range, in order to avoid excessive compression / expansion,
which may lead to too low or distorted output signals.
A 1:1 ratio is an invalid setting, as the AGC does not operates at all.
Enable: toggles the AGC (keep it on when using).
AUTOMATIC GAIN CONTROL (AGC)
