CONNECTION JACKS
1.
OUTPUT
Connect to guitar amplifier,
mixer, or audio
amplifier.
If
you
use
an
effects unit like
an
echo chamber, connect
it
between the
output
jack and the amplifier.
When
using
audio
amplifiers
such
as
those
in
home
stereo systems,
use caution with the
volume control because
the synthesizer
is
capable of generating
sound
levels
high
enough
to destroy the speakers.
2.
OUTPUT LEVEL
Set
this
switch to
L,
M,
or
H
according
to
the
input sensitivity
of the amplifier used. Set to
L
or
M
for an ordinary guitar amplifier
and
to
H
for
an audio amplifier or
mixer.
3.
PHONES JACK
Connect headphones
to this jack.
Use
head-
phones
designed for
normal
home
stereo
systems.
Roland RH-1 headphones
are suited
for this
purpose.
The output
level
from
this
jack
is
constant,
independent of the
TOTAL
VOLUME
setting.
Therefore,
you
can turn
down
the
volume from
the
speaker
when
adjusting
sounds with the headphones. This
is
very convenient for setting
sounds on
stage.
4.
PHONES OUTPUT LEVEL
This switch changes
the
output
level at
the
PHONES
jack. Set
it
at
the position to
suit
the sensitivity
of the
headphones you
use.
5.
PEDAL
CONT
VCF
A
pedal like the
FV-1 or
FV-2
can be connected
to
this
jack to control the Cutoff
Frequency
of the
VCF.
The pedal functions
as
a
wah wah
pedal
when
the
VCF
RESONANCE
control
is
raised.
CAUTION:
Be
sure to
use the foot pedal's
OUTPUT
jack
and not
its
INPUT
jack.
The
OUTPUT
jack
is
on
the right side of
the
FV-1
and on
the
left
side
of the FV-2.
6.
EXT
SIG
INPUT
Connect external sources
such
as
a
microphone,
electric guitar, electric
piano, or
strings
to
this
jack.
As
the
SH-7
incorporates
an envelope follower,
the
VCF
can be controlled
by the
level
of the
signal
from
the external
source to use the
SH-7
as
a kind of
effects unit
like
automatic
wah.
When
connecting the strings
such
as the
Roland RS-202, connect the gate
output
also
to
make
it
possible to
control the envelope
generator of the
SH-7 from the
strings
key-
board.
With
this
setting,
the
VCF
can be
activated
on
brass
chords
producing sounds
like
a
polyphonic
synthesizer.
7.
EXT
SIG INPUT
LEVEL
This
is
a level
changeover switch
for the external
input. Set to
H
for
microphone,
to
M
or
H
for
an
electric or
electronic
instrument.
When
connecting
a
tape
recorder or other
audio
devices, set to
L.
If
the output
level
is
low even
when
the
EXT
SIG control
on
the
AUDIO MIXER
is
set to
maximum,
set
the
EXT
SIG
INPUT
switch
a
step higher.
If
the
sound
is
distorted
by excessive
input,
change
to a
step lower.
8.
TRIG INPUT
This jack receives
external trigger pulses.
When
+1
5V
pulse
is
fed to this jack,
the
SH-7
gate
is
triggered.
9.
GATE
INPUT
This
jack receives
gate pulses
from
sources
such
as
the
VK-6
or
VK-9
Organ, the
Model
104 (System 100) or
Model
717A
(System 700)
Analog Sequencer, the
MC-8 MicroComposer,
the
RS-202
String Synthesizer, etc.
10.
CV INPUT
In
the
same way
as
the
above Gate
Input,
control voltages
from external sources
can be
connected
to this jack.
When
connecting
external control voltages to
control the SH-7, be sure to set
the
KEY
MODE
switch to
EXT
position. (See page'8).
11.
GATE OUTPUT
The
gate
output from
the
SH-7 keyboard can
be taken
from
this jack.
Connect to the gate
input of
an external synthesizer or
the
MC-8
MicroComposer
for control of
such devices
with the
SH-7 keyboard.
12.
CV OUTPUT
This jack
outputs control voltage
from
the
SH-7
keyboard.
Connect
to the
CV
input to an
external synthesizer or the
MC-8 MicroComposer
to control
such devices with the
SH-7 keyboard.
