Analogue inputs
The
MIC
1/P
[XLR] and
LINE 1/Ps
[XLR
and%"
TRS
Jack]
can
be
used to
connect
an
analogue
source
to
ISA One. If
a
microphone
is
connected
to
the
MIC
1/P,
phantom
power
can
also
be
supplied
by
making
sure
MIC
is
selected
using
the
INPUT
switch
on
the
front
panel,
then
activating
the
+48V
switch.
If
you
are
unsure
whether
your
microphone
requires
phantom
power,
refer
to
its
handbook,
as
it
is
possible
to
damage
some
microphones
[most
notably
ribbon
microphones]
by
providing
phantom
power.
If
wanting
to
record
a
Line-level
signal
then
you have
the
choice
of using an XLR
or
balanced
Jack
connector.
Once
connected,
simply
use
the
INPUT
switch
on
the
front
panel
to
select
LINE.
