LO/HI
AUDIO
OUTPUTS
The
/AUD/O
OUTPUTS
are
used
to
route
the
audio
(sound)
output
of
the
Multimoog
to
a
monitoring system
to
create
sound.
LO
AUDIO
is
a
low
level
(-10
dBm)
output
suitable
for
connection
to
a
P.A.
or
guitar
amplifier
that
has
its
own
preamplifier.
HI
AUDIO
is
a
high
level
output
(+12
dBm)
capable
of
direct
connection
to
many
power
amplifiers.
Like
an
electric
guitar,
the
Multimoog's
audio
output
may
be
modified
using
a
phaser,
wah-wah
pedal,
fuzz,
or
other
sound
modifier
to
create
special
effects.
In
particular,
Moog900
Series
modules
may
be
used
to
modify
audio
output.
For
instance,
audio
output
could
be
passed
through
a
Moog
907
Fixed
Filter
to
create
"peaks"
(like
equalization
but
much
stronger)
in
the
harmonic
spectrum,
radically
changing
timbre.
The
907
creates
conditions
similar
to
the"formants"
present
in
many
acoustic
instruments.
For
example,
the
bassoon
has
a
formant,
or
resonant
region,
arou
nd
500
Hz
that
is
present
throughout
most
of
the
playable
range
of
the
instrument.
Use
of
the
907
Filter
to
create
a
peak
at
500
Hz
would
cause
the
sound
output
to
have
a
formant
at
that
frequency,
enhancing
the
imitation
of
the
bassoon.
The
Multimoog
is
particularly
suitable
for
use
with
modular
equipment,
since
the
Multimoog
also
externalizes
trigger
and
control
signals
used
for
effective
communication
between
instruments.
AUDIO
INPUT
The
AUDIO
INPUT
is
a
single
function
jack.
Its
purpose
is
to
allow
feeding
the
sound
of
other
instruments
through
the
Multimoog
for
modification.
You
may
input
any
external
audio
signal,
such
as
the
output
of
electric
guitars,
organs,
pianos,
tape
recorders,
and
microphones
into
this
jack
on
the
Multimoog.
The
AUDIO
INPUT
is
fixed
in
sensitivity;
it
is
adequate
for
the
output
level
of
many
electronic
instruments
(100
mV
RMS
input
required
for
full
drive;
input
impedance
is
100K
Ohms).
In
some
cases,
as
with
dynamic
microphones
or
guitars
with
low-
level
pickups,
preamplification
before
introduction
to
the
AUDIO
INPUT
may
be
necessary.
Many
guitar
amps
provide
a
separate
preamp
output
that
can
be
used
for
this
purpose.
When
an
external
audio
signal
is
fed
into
the
AUDIO
INPUT,
it
appears
at
the
audio
input
of
the
FILTER
section
and
follows
the
normal
audio
signal
path.
It's
important
to
remember
that
when
you
connect
an
instrument
like
the
guitar to
the
AUDIO
INPUT,
only
an audio
signal
is
provided
to
the
Multimoog.
The
external
instrument—the
guitar—
doesn't
produce
control
and
trigger
signals.
A
simple
AUDIO
INPUT
connection
won't
control
the
oscillators
to
make
them
"follow"
the
tune
played
by
the
guitarist.
And
the
contour
generators
in
the
Multimoog
will
not
be
triggered
by
the
articulations
of
the
guitarist.
So,
for
basic
use
of
the
AUDIO
INPUT
remove
the
oscillators
from
the
audio
signal
path
(place
OSCILLATORS
switch
to
OFF);
and
bypass
the
internal
voltage
controlled
amp
(place
BYPASS
switch
to
ON)
so
the
guitar
may
be
heard:
