Recording a line-level source
To
record a
line-level
signal
with
ISA
One,
carry
out the
following
steps:
1.
Connect
the
line-level
signal, using either an XLR
or
a
114·
·
TRS
Jack cable, to the appropriate
LINE
1/P
on
the rear panel
2. Select
LINE
as
the input source using the
INPUT
switch
3.
Set the gain of the line signal using the two dials
on
the
front
panel and observing the
VU
meter
or
left-hand
LED
meter.
The stepped gain dial sets the level
in
10d8 steps,
with
the Trim dial adding a
further
20d8
on
top
The
line-level
signal
will
then
be
sent to the MAIN
0/P
on
the
rear
panel,
as
well
as
to
the
first
channel of the
ADC
[if installed).
Recording
an
instrument
To
record a
guitar
or
bass
with
ISA
One,
carry
out the
following
steps:
1. Plug
the
instrument
directly
into the
Dl
input
on
the
front
panel
2.
Connect the
AMP
output
on
the
front
panel to your
guitar
amp if one
is
in
use
3. Set the gain of the
instrument
using the
GAIN
dial
4.
Use the
right-hand
Z
IN
switch if wanting
to
obtain
more
or
less level
or
high frequency
from
the
instrument
[see the
Mic Preamp
Input Impedance
section
for
details)
Even
with
MIC
or
LINE
selected
by
the
INPUT
switch, the [direct)
instrument
signal
will
then
be
sent to the
Dl
0/P
on
the
rear
panel
[this
is
always the case,
regardless
of settings),
as
well
as
to the second channel of the
ADC
[if installed). Without
INST
selected
by
the
INPUT
switch, the level of the
instrument
can
be
viewed
on
the right-hand
LED
meter
. If
wanting to record the
direct
and
amplified guitar, a microphone can then
be
used
simultaneously
with
ISA
One
for
that purpose [see the next section
for
details).
Select
INST
using the
INPUT
switch if wanting to route the
instrument
signal through
ISA
One·s
main recording path. The benefit's of
this include:
•
The
Insert
can
be
used to add effects and additional processing
•
The
VU
meter
can
be
used to view t
he
signal,
in
addition to the
LED
meters
The
EXT
1/P
can
be
used
for
monitoring and
digital
conversion
• Clean
and effected versions of the
instrument
can
be
recorded using the
Dl
and
MAIN
outputs, respectively
Two-channel recording options
ISA
One
can
be
used to record an
instrument
and a mic
or
line signal
simultaneously
. This is because,
with
MIC
or
LINE
selected
using the INPUT
switch
on
the
front
panel, an
instrument
connected
to
the
Dllnput
will
still
be
fed to the
Dl
0/P
[on the
rear
panel)
and
to
the
ADC
[if installed and nothing
is
connected to the
EXT
1/Pl.
For example, a recording setup that uses this could
be
one
where
a
guitar
player and vocalist are to
be
recorded at the same
time
.
In
this instance, the vocal
would
be
recorded using a microphone connected to the
MIC
XLR
Input
on
the
rear
panel,
with
MIC
selected
using the
INPUT
switch
on
the
front
panel. This signal is then sent to a recording medium using
either
the
MAIN
0/P
on
the
rear
panel
or
an
output
on
the
ADC
[if installed).
At the same time, the
guitarist
could
be
plugged
in
directly
to
the
Dllnput
on
the
front
panel. The
guitar
signal [now balanced and
with
lower
output
impedance) can then also
be
sent to a recording medium, this
time
from
the
Dl
0/P
on
the
rear
panel.
