7. HI
If you turn this control up, you will boost all the frequencies above 12
kHz (shelving filter). You will add transparency to vocals and guitar and
also make cymbals crispier. Turn the control down to cut all frequencies
above 12 kHz. In such way you can reduce sibilance of human voice or
reduce the hiss of a Tape player.
8. MID
This is a peaking filter and it will boost/cut frequencies from 100 Hz to 8
kHz depending on the position of the MID freq control. This control will
affect especially upper male and lower female vocal ranges and also
the harmonics of most musical instruments.
9. HI-MID
This control gives you up to 15 dB boost/cut at 3 kHz. It is useful for
controlling voices. You can accurately polish your performance via
adjusting this knob.
10. MID-LOW
This control gives you up to 15dB boost or cut at 500Hz.
11. LOW
If you turn this control up, you will boost all frequencies below 80Hz.
You will give more punch to bass drum and bass guitar and make the
vocalist more “macho”. Turning it down, you will cut all the frequencies
below 80Hz. In this way you can avoid low-frequency vibrations and
resonance, thus preserving the life of your woofers.
12. AUX SENDS Level Control
These four controls are used to adjust the level of the respective signal
sent to AUX bus, AUX1 and AUX2 can be switched to PRE/POST-
FADER via the PRE/POST switch, so, generally, they can be used
for monitor application and effects & sound processors input. AUX3
and AUX4 are configured as POST-Faders. In this typical compact
unit, excluding sending out the signal directly to the external effect
or processor equipment, AUX SEND3/4 can also be assigned to the
internal onboard effect module.
13. PRE/POST Switch
This switch is used to select pre- or post-fader for signal sent from input
channel to AUX sends bus 1-2. When you turn this switch to “pre”, the
pre-fader signal will be sent to the corresponding AUX bus pair.
14. PAN/BAL Control
Abbreviation of PANORAMA control for mono channels, or the stereo
channels, always says, BALANCE control. Keep this control in centre
position, then the signal will be positioned in the middle of the stage.
15. MUTE Switch & LED
Each channel is equipped with a MUTE switch. The LED next to it
illuminates, when the MUTE section is activated. Pressing this switch
is equal to turning the fader down, which can mute the corresponding
channel output except for the channel INSERT send.
16. PFL (pre-fader listen) Switch & LED
Each channel has a PFL switch which will send a signal from a post-EQ pre-fader location to the AFL/
PFL mix bus. This LED illuminates when the PFL is turned down. Use this when you wish to use the
headphones to monitor only a specific channel. Moreover, you can monitor a channel no matter the
channel fader is lowered or the MUTE switch is on when this PFL switch is engaged. This will not affect
the signals that are sent to the MAIN MIX bus and AUX buses.
