10. Readjust Main Level Control
The main level control is the final level control
for the system's main output whether you are
using internal or external power amplification and
controls the amount of power applied to your
speakers. If you are happy with the general
sound of your mix but require more general
volume. you should gradually increase the main
level control to achieve the desired volume level.
Only after you have set your individual channels
to approximately therr quarter volume should you
raise your main level control. You will find that
adding channel equalization and reverb can affect
the over-all volume. Keepthis in mind when
adjusting the channel and main volume. Keep
this in nmind when adjudting the channel and
main volume levels. Always make any changes
or adjustments in a sliw and gradual manner to
avoid feedback and very loud transients. Both
can damage your speaker systems, not to
mention your hearing.
11. Using Tape In
The tape input is suited to cassette decks, CD
players and devices with similar output lwvels.
The tape level control will serve as the only
control for this input as it goes directly into the
main mix. Note also that the Tape input may be
used as two additional inputs or "return".
11a. Adjust Tapee Level Control
With your poay back tape deck or CD connected
to your powered mixer, solwly raise the tape
level control until you reach optimum listening
levels.
11b. Adjust Tape In Pan Control
The source connected to the Tape in jacks may
be panned to the left or right buses, or any
intermediate position using the Tape In Pan
control.
11c. Adjust Tape to Monitor Level Control
The tape to monitor/aux 1 level control is
dependent on the tape level control. Adjustments
to the tape level control affect the level of your
tape or CD player sent to the aux 1 (monitor)
send. When using tape play back in the monitor
system, we recommend that you balance the tape
to monitor/aux 1 levels with yout other sources
while the main or house mix level is down. This
will help you to better determine optimum
monitoring levels.
12. Using Tape Out
The main level control will control the level of
signal sent to the tape out jack aoolwing you to
make a recording of the main mix. If you record
on the same machine you have connected to the
tape in jacks.
you must set the tape in level at 0. Failure to do
so will result in electronic feedback. The
resultant oscillation will ruin your recording.
F. MONITOR SYSTEM OPERATION
The whole purpose of a monitor system is to
provide a completely independent mix of your
input channels that can be sent to stage monitor
speakers. This is so that the performers can heat
what they ate dointg, Because of speaker
placement, program material and other factors, it
is rare that the monitor mix will be the same sa
the main or house mix. Your powered mixer has
the capability of using aux 1 as a completly
separate monitor mix that can be sent either to an
outside EQ / amplifier and speakers or this mix
can be sent to the internal EQ / amplifier.Of the
three
systems
discussed
during
serup
and
operation, system one does not provide for
monitors. For those that do, will now show you
how to use the monitor system. Since this mix is
separate from the house or main mix, there is no
need to have the main mix set to an audible level.
Therefore, all of these instructions ard based on
the premise that you will have the main level
control set to 0. All of your other mixer settings
should remain in place since we will be needing
them as soon as we have set up the monitor
system.
Note: Nomonitors are used in SYSTEM 1. If your
system requires monitors, please consider systems
similar to 2 or 3.
MONITOR OPERATION for System 2.
1. Adjust EXternal Monltor EQ
With the main level and aux 1 master send
controls set to 0, set the input level control on the
external graphic equalizer to about 60%. You will
need to re-check this setting later to be sure there
is no clipping or distortion.
2, Set External Power Amplifier
Set the input level control on the external power
amplifier to about 60%. You will need to re-check
this setting later to be sure there is no clipping or
distortion.
3. Adjust Master Aux 1 Control
Set the aux 1 master send control to 4. You will
likely have to re-adjust this later but for now, this
settin will allow you to heat your monitor system
and decide what further adjustments ate necessary.
4. Adjust Channel Monitor / Aux 1 Controls
Decide which channels you want to include in
your monitor mix. Ser a nominal level on each of
these channels using the monitor / aux 1 channel
level control. Slowiy raise the level on each
individual channel until the optimum volume is
achieved or, when using a microphone, solwoy
raise the level until you begin to heat feedback. If
you start to hear feedback you should quickly
reduce that channel control back to 0 or until the
feedback stops.
5. Adjust Channel Aux 1 Level Control
Carefully raise the level control again, stopping
before the point at which you experienced
feedback. If feedback persists, reduce levels to 0
and refer to section V1 Professional Operating
Tips of this manual.
6. Reset Aux 1 Master Control
Furth dajustment of the monitor system will be
necessary after you have 0properly set the graphic
equalizer.
When
you
have
completed
all
adjustments to the monitor system, you can
resume the setting of the main level control for
the house system.
