Submixing with Two EM-Mixers
There are several ways to connect two EM-Mixers
together. One easy method allows all the channel inputs
of each Mixer to feed both the Monitor and Speaker
outputs. |
To accomplish this:
1. Plug the Line outputs of Mixer 1 into the Aux
Inputs of Mixer 2.
2. Plug the Monitor Outputs of Mixer 2 into the
Monitor Sub Inputs.of Mixer 1.
3. Patch the Monitor Outputs of Mixer 1 into the
G-EQ Inputs of Mixer 1.
4. Plug the. main speakers into the Speaker Outputs
of Mixer 2, and the monitor speakers into the Speaker
Outputs of Mixer 1.
All channels of each mixer can now feed both the
monitors and main speakers, Overall monitor levels
are now controlled with the Master Monitor faders on
Mixer 1, and overall program levels are controlled by
the Master Program Faders on Mixer 2.
This method facilitates the use of "subgroups" for
easier mixing. For example, if you use an ЕМ-150 В
for Mixer 1, and an EM-300B as Mixer 2, you could
send your vocals and percussion into Mixer 1, and all
other instruments into Mixer 2. By Planning all vocals
in Mixer 1 fuli left and all percussion full right, you
would be sending separate and complete vocal and
drum mixes to the Master Aux controls of Mixer 2.
Using the. Aux Pan controls on Mixer 2, you can then
position the vocals and the drums independently any-
where in the stereo perspective. This allows you to vary
the level of all vocals or all the drums, simply by varying
the Mixer 2 Master Aux In 1 and 2 controls. Similarly,
the Master Program Faders on Mixer 1 now serve as a
subgroup for all Mixer 1 inputs feeding the Program
outputs, and the Master Monitor faders on Mixer 2 now
serve as subgroups for all inputs on Mixer 2 being fed to
the monitors.
An additional advantage in this example is the ability
to use Graphic Equalizers for each channel of both the
main and monitor speakers, with different EO for each.
CAUTION: Use extreme caution when connecting two
mixers. Be certain that you patch connections so that
no output can be fed to an input which would again be
fed to the same output. In some instances the setting of
a channel mix or monitor send control may be the key
to avoiding this situation. Should you allow an output-
to-input loop to occur, the result will be feedback
(howling), oscillation, and possibly severe damage to the
Mixer or other sound system components. Yamaha is
not responsible for any such damage due to negligent
or improper use, and such use may void the Warranty.
