Create IEM Mixes with Ambience
In Monitor mode the
matrix continues to be fed with the 4 groups, L and R mixes. You can
use these to create additional, independent monitor mixes. Together
with the auxes these give you as many as 10 mixes. Create mono or
stereo in-ear monitor feeds using single or paired matrices, for
example MTX1-2 and 3-4. You could use LR to start with a basic
stereo mix, then add up to four instrument or ‘more me’ groups. Add
ambience using a pair of jack leads to patch the stereo channel MIC
Outputs 15 and 16 into matrix EXT IN 1 and 2. With nothing plugged
into EXT IN 3 and 4 the two mic signals are automatically linked
across making the same stereo ambience available to both IEM mixes.
Alternatively you could use an outboard reverb effects processor fed
from a post-fade aux send to create the ambience. Use the channel
faders and pan to create the basic stereo mix. Remember to set the
other monitor aux sends to pre-fade.
Using the Matrix to create a Recording
The band may be
acoustically loud in the room, and you need only mix vocals and some
of the instruments into the PA to get good clarity and overall balance
for the listeners. If you recorded the console main output you would
be disappointed when you got home and listened to the result. For
example, there may be strong voices, acoustic guitar and flute, but the
drums, bass and electric guitar may be low. This is because you did
not need much of these backline instruments in the PA mix. However,
if you use the matrix to feed the recording you could start with the
main LR (PA) mix, then turn up the drum and guitar groups to
compensate for the lack of these in the house system. You could also
add in ambience as described above to give the recording more life
by including audience reaction and natural reverberation.
Recording with the
GL2400
The console is equally at
home recording live or in the project studio. The studio grade
preamps produce an accurate and noise-free recording. Create a
stereo recording from the main LR output, or from a pair of matrices as
described above if recording and mixing live at the same time. To
record to multitrack use whichever combination of groups, matrix,
auxes and channel direct outputs is most convenient. The direct
outputs are set pre-insert, pre-EQ as factory default. This setting
means that the recording is not affected by your live fader and EQ
changes. Note that you can swap internal jumpers to change this to
post-EQ, and post-fade if you prefer. Post-EQ lets you use the EQ for
source correction to affect both live sound and recording. Remember
to use some ambience microphones to record the audience and
venue atmosphere too.
Pre/post Fade Aux Settings
The aux sends are switched pre
or post fader using two PRE switches on every channel. One switch
affects auxes 1-4, the other auxes 5 and 6. It is usual to set auxes pre-
fade if you are mixing monitors from FOH. Set post-fade for auxes
used as effects sends, zone feeds, aux-fed subs and so on. If you are
using the console to mix monitors only then the auxes are typically set
post-fade so that the channel fader becomes the source master to all
monitors. In this case start with all channel faders set to ‘0’.
There are times when you may want some monitor sends set post-
fade while most are set pre-fade, for example mixing monitors with
radio mics and cued sound effects. Here, it may be better for the
radio mics to follow your fader movements so avoiding off-stage chat
or noise in the monitors.
For this reason we believe it is important
that channel rather than global mix pre/post switching is provided.
