Side
Tone
Controls
Each
channel
has
a
"Side
Tone"
null
control.
This
control
is
used
to
set
the
amount
of
the
microphone
that
is
heard
In
the
earphone
from
that
channel.
This
control
Is a
true
hybrid
null
control
and
therefore
is
sensitive
to changes
in
line
loading.
For
headphone
use
it
is
best
to
find
the
'null'
for
a given
channel
and
then
rotate
the
control
clockwise
to
obtain
the
desired
side
tone
level.
If an
external
speaker
Is used
providing
a
possible
acoustic
feedback
path
it will
be
necessary
to
use
an
almost
complete
'null'
of
the
side
tone
control.
