1. Power Switch
This switch controls the AC mains power to your
powered mixer. Power is on when the switch is in
the on(up) position and is confirmed when the power
LED indicator is illuminated.
2. Fuse
The fuse is located in the fuse holder. (See Section 9
Specifications for the correct values.)
3. Line Cord
For safety, all units are equipped with a three
conductor line cord.
4. Phantom Power Switch
Phantom power is provided for condenser microphones
that may require such power. In the on (in) position,
this switch provides 48VDC phantom power to all
microphone inputs
5. Right/Monitor Speaker Output Jack
These two parallel speaker output jacks accept
standard 1/4
＂ two-conductor phone plugs, providing
750 watts of power at 4 ohms, or 430 watts at 8
ohms. Load impedances less than 4 ohms will not
draw additional power and may cause the unit to go
into protect mode.
Warning: failure to correct this can result in
damage to your unit!
The function of these jacks depends upon the position
of the Amp mode select assign switch(located on the
master section of the front control panel).
If the Amp mode select assign switch is in the stereo
position (not Pushed in), the unit is in the left &
right mode. The power amplifier driving these outputs
then gets its signal from right main bus, the output
level is controlled by the master level control, and the
lower 5-band EQ is used for final equalizing of the
right side.
If the Amp mode select assign switch is in the
L
+R/monitor position(pushed in), the unit is in the
Main+Monitor mode. The power amplifier driving
these outputs then gets its signal from the monitor
circuit. The output level is controlled by the monitor
level control, and the lower 5-band EQ is used for
final equalizing of the monitors
.
6. Left/Main Speaker Output Jack
These two parallel speaker output jacks accept
standard 1/4
＂ two-conductor phone plugs, providing
750 watts of power at 4 ohms, or 430 watts at
8ohms. Load impedances less than 2 ohms will not
draw additional power and may cause the unit to go
into protect mode.
Warning: failure to correct this can result in
damage to your unit!
The function of these jacks depends upon the position
of the Amp mode select assign switch(7) is in the
stereo position (not Pushed in), the unit is in the left
& right mode. The power amplifier driving these
outputs then gets its signal from left main bus, the
output level is controlled by the master level control,
and the upper 5-band EQ is used for final equalizing
of the left side.
If the Amp mode select assign switch(7) is in the
L+R/ monitor position(pushed in), the unit is in the
Main+Monitor mode. The signal from the right and
left buses is combined and feeds the power amplifier
that drive these output jacks.
The output level is controlled by the master level
control and the upper 5-band EQ is used for final
equalizing of the main speakers.
7.SPEAKON TYPE
▪ Speakon Connections
Speakon connectors are purpose-built for low
voltage,
high current applications.
Each connector incorporates two pair of conductors,
labeled 1+, 1-, by convention, single.
When attaching NL4FC mating connectors, be sure to
insert the connector to its full depth, then turn the
connector 45°clockwise to lock it in place
.
