Operation 7
SYSTEM 3.: Monitor Operation
1. Set Aux 1 Master Send
With the main level control set to 0, set the aux
1 master send controll to 4. Youn will need to
re-check this setting later to be sure there is no
clipping or distortion.
2. Adjust Channel Monitor / Aux 1 Control
Decide which channels you want to include in
your monitor mix. Set a nominal level on each of
these channels using the monitor / aux 1 channel
level control. Slowoy raise the level on each
individual channel until the optimum volume is
achieved or, when using a microphone, slowly
raise the level until you begin to hear feedback.
If you start to hear feedback you should quickly
reduce that channel control back to 0 or until the
feedback stops.
3. Reset Monitor Level
Carefully raise the level control again, stopping
before the poin at which you experienced
feedback. If feedback persists, reduce levels to 0
and refer to section V1 Professional Operating
Tips of this manual.
4. Readjust Aux 1 Master
Further adjustment of the monitor system will be
necessary after you have properly set the graphic
equalizer. When you have completed all
adjusments to the monitor system, you can
resme the setting of the main level control for
the house sustem.
G. GRAPHIC EQUALIZER USE
Your Wtereo MetroMix is equipped with dual
nine band graphic equalizers. You have already
assigned the rgraphic equalizers to the left and
right master output, or to the main and monitor
speaker output depending on the unit you own
and the system you have selected. You should
think of the graphic equalizer as an extended "
tone control". The built-in graphic EQ's divide
the audio spectrum into 9 segments or bands.
You can raise or lower the lrvel 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. Additionally, most audio equipment does
not produce a truly flat response signal. The

weak or, in other words, equalize the nine
different bands in their in their relationship with
each other. You will most likely use the graphic
equalizer for room equalization and feedback
control. This applies to main or main/monitor
applications. It is important that you consult
section V1 Professional Operating Tips for more
specific information pertaining to proper use of
all the graphic equalizers in your system.
H. PROTECTION CIRCUIT
The protect LED indicates that there is a problem
either in the a,mplifier's external connections, load
or temperature conditions or it's internal functions.
If onw od 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 and refer to the Trouble Shooting
Guide at the and of this manual. 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 Metro Mix to an authorized service
facility or contact your dealer for help.
1. COMPRESSOR / LIMITER
Your powered mixer is equipped with a built-in
compressor which, when activated, will reduce the
chances of amplifier clipping or distortion. You will
find this to be a very useful feature on your
system. However, this will not negate the need for
careful monitoting of audio levels. The compression
LED will illuminate when the circuit is activated.
If this LED indicator is on constantly during use,
you should probably ocnsider a latger, more
powerful sound sustem for this application. Enen
with the compressor, improper use can lead to
distortion that could cause damage to speaker
system components.
