2. Use the MONITOR BAL knob to adjust the volume bal-
ance of the master output sound and the CUE bus
sound.
Use the MONITOR LEVEL knob to adjust the overall volume.
3. By turning the SPLIT switch on, you can hear the CUE
signal from the L side of the monitor, and the master
output from the R side of the monitor.
When SPLIT is on, the MONITOR BAL knob does nothing.
3. Equalizer
Using the equalizer to adjust the sound
Traditionally, an equalizer (EQ) divides the sound into different frequency
regions, allowing you to shape the tonal character of the sound by boost-
ing or cutting the output of each region. In more modern applications, the
EQ can be used as an effect, providing filter sweeps and isolator functions.
The ZERO4 provides 11 different types of EQ.
1. Use the EQ SELECTOR knob to select the equalizer
type.
EQ type:
These are a variety of EQ types with frequency re-
sponses suitable for different styles. Choose the type that’s ap-
propriate for your needs.
1. Zero EQ
2. Boost
3. Hyped
4. Round-Q
5. Slamming
ISOLATOR type:
This is a -12dB/oct isolator. It divides the in-
put sound into frequency regions, and allows you to individu-
ally cut the sound of each region. If you turn the knobs of all re-
gions completely toward the left, the sound will disappear com-
pletely.
6. ZERO Isolator
7. ZERO ISOLATOR WIDE DIVIDER
8. ZERO ISOLATOR LOW
FILTER type:
These are filter types in which HI is an LPF and LO
is a HPF. Turning HI down (toward the left) will lower the cutoff
frequency of the LPF. Turning LO down (toward the left) will
raise the cutoff frequency. MID operates as a peaking EQ.
9. ZERO FILTER
10. ZERO FILTER DENSE
11. ZERO FILTER SPIKY
2. Use the EQ knobs to control the type of EQ you se-
lected.
Adjust the three bands (HI/MID/LO) to obtain the desired tone.
