Ihe
foltowing functions are
not
in
the signal
path,
but
are
useci to control
the basic bit rate
clock
to
create strEcial effects
other than those that
resul-t
by sinple
feedback.
Ihere are three front
panel
controls whose
function
is
to
provide
a
control
rroltage
into
the
precision
Voltage
Controlled
Oscillator
(WO)
used as the
digital bit rate and sanpling
clock.
For
exanple,
a control
voltage
of
0
to 5 rrcIts
will
vary
ttre
clock
for 250
kHz to
1 MHz
wtrich
results
in
a four
to one
(two
octave) range.
Setting
ttre
WIUffi
control,
located
on
the
front
panel,
in
ttre 0
position,
ttre DEISY FACIOR control
(a1so
located
on ttre front
panel) provides
ttre
required voltage as shovnr
below
in ttre
block
diagram.
WLren an
external
signal is atrplied to ttre @IVIROL
jack
located
on the rear
paneI,
the DEIAY

The
WIII{III
control
is
used
in
conjunction with
ttre
SPEED
control located
on
ttre
front
panel
to apply a Iow
Frequency
Oscillating
(tFO)
rzoltage
to
the
\rcO inprt.
the
L,FO
is a
sinusoid
wtrose
frequency is
controlled
by
the SPED
control. The
I{U}IH
control determines
ttre amplitude fed into
the
\DO.
It
can
be
seen that
jnternediate
settings of thre
IfiUIH
control
wil-]
cause a
mix
of
bottr the
DSAY FACIOR setting
and
t-lTe
LFO
outtrut.
A1so,
l*ren
a
rcltage
is applied to
the
external @NIROL
jack,
ttre
WIDIII will
likewise
mix
internal LtO
settings
with
ttre external
control voltage
--
all
of
tftich
makes
for
interesting
effects. Ibte
ttrat ttre WIEIIH
control
provides
a
greater
than 4-to-1 s*eep range.
Ihe
EFFECIBON
II is basically a
simple to understand
device, but because of
its
sinplicity
it
is
a very
trnwerful
effects
tool.
