10. Connect the Monitor speakers.
Using heavy gauge unshielded 1/4
″
speaker cables, connect
your monitor speakers to the output jacks of the monitor power
amplifier. make sure that the total impedance load of your
monitor speakers is not less than the recommended minimum
impedance that your monitor power amp can safely handle
.
A. MONITOR OPERATION
The idea behind a monitor system is to provide a completely
independent mix of your input signals to your monitor speakers
so that the performers can hear what they are doing and
perform their best.
Because of speaker placement, program material, and several
other factors, it is rare that the monitor mix will be the same as
the main mix.
1. Set the Master Level Control to Zero.
Since the monitor mix is completely separate from the main mix,
all of the monitor settings will be initially made with the master
level control set to the zero position
.
2. Set the Monitor Level Control to Zero.
3. Set the input Level of the External Monitor
Equalizer(if applicable).
If you are using a separately powered monitor system, set the
input level control of the equalizer to about 60%. you will need
to check this setting later to be sure there is no clipping or
distortion
.
4. Set External Monitor Amplifier(if applicable).
If you are using a separately powered monitor system, set the
input level control of the external amplifier to about 60%. you
will need to check this setting later to be sure there is no
clipping or distortion.
5. Set the master Monitor Level Control.
Set the monitor level control to 4. you will likely have to
re-adjust this later, but for now, this setting will allow you to
hear your monitor system and decide what further adjustments
are necessary.
6. Set the channel Monitor Controls.
Decide which channels you want to include in the monitor mix.
set a nominal level on each of these channels using the
channel monitor control. Slowly raise the level on each individual
channel until the optimum volume is achieved or, in the case of
a microphone channel. until you begin to hear feedback.
If you start to hear feedback, quickly reduce the monitor control
of that channel back to 0 or until the feedback stops. Carefully
raise the control again, stopping before the point at which you
experienced feedback.
7. Adjust the Monitor Equalizer.
Make any adjustments necessary in the monitor equalizer. If you
are using a separatedly powered monitor system, you will adjust
the external monitor equalizer. If you are using the VM11S-DRV
in the Main+Monitor Mode, the lower equalizer on the mixer
controls the monitors
8. Make final adjustments to the monitor system.
After you have properly set the graphic equalizer, Make any
further adjustments to the monitor system that are necessary.
When you have completed all adjustments to the monitor
system, you can raise the level of the master control for the
main system.
B. GRAPHIC EQUALIZER USE
The VM8-DRV is equipped with a single 7-band equalizer that
cab be configured to affect either master output of main output.
The VM11S-DRV/VRM11S-DRV is equipped with two 7-band
equalizers that can be configured to affect either left/maint
outputs or right/monitor outputs.
The VM11T-DRV/VRM11T-DRV is equipped with three 7-band
equalizers that can be configured to affect either left outputs or
right outputs or monitor outputs.
You should think of the graphic equalizer as an extended "Tone
Control." the built-in graphic equalizer(s) divide the audio
spectrum into 9 segments or bands. you can raise or lower the
level of each individual band by adjusting the slider on that
band. Any environment has its own set of acoustics, even
outdoors. Some environments will reflect or absorb certain
frequencies more than others. a graphic equalizer allows you to
attenuate ranges of frequencies that are too strong and boost
others that are too weak, or, in other words, to "Equalize" the
seven different bands in their relationship to each other.
C. PROTECTION CIRCUIT
The protect LED indicates that there is a problem either in the
amplifier's external connections, load or temperature conditions or
it's internal functions.
If one of these situations occurs, the amplifier senses the
problem and automatically switches into its "Protect Mode". The
LED will light to warn you of the trouble and the amplifier will
stop working.
If the LED lights and stays on, switch the unit off.
If you feel that you have been able to correct the fault condition
that caused the unit to go into the protect mode, switch the
mixer on again.
If you have successfully removed the fault condition, the
amplifier will run normally.
Caution : If the protect LED remains lit when
attempting to resume operation, DO NOT USE
THE
UNIT. Take your VM Mix to an authorized
service
facility or contact your dealer for help
