Acoustic 136 - Bright Switch

f NPUTS
(Hish
and Low
Gain)
(U
(21
The first
input
(1)
is louder than
the second input
(2).
The first
input
(1)should
be used in
most cases to achieve
maximum signal-to-noise ratio;
however,
if
your
instrument
puts
out such
a
large
signal that
you
can
turn
the volume
control
just
a
little
bit
above
the off
position,
then
use the
second
input
(2)
to
cut down on the
signal. There
is no
difference in tone
between the
two inputs
-
only volume.
(No.
2 is 10
DB lower
than No.
1.)
BRIGHT
SWITCH
(3)
In
the BRIGHT
position,
the
treble is
boosted in relation
to the
bass and
mid-range. lt
is most
active
at
lower
volume
control
settings
and
decreases in
activity
as the volume
control
(4)
is
advanced
to avoid feedback
and
oscillations
at high volume.
VOLUME
(4) (71
The Volume
Control
(4)
increases
the volume
of all
frequencies
and special
functions
equally
with
the
exception
of the Bright
Switch
(3).
(See
aborye.)
TREBLE
(5) (B)
The
treble
circuitry is
of the
cut
and boost
type. This
type
of control
allows
you
a
great
deal
of treble
boost,
as
well
as sufficient
treble
cut for
maximum
sustain
in
the
mid-range
at higher
power
levels.
Always
keep
in
mind
that straight
up is flat.
Turning
the
treble
control
to the
left
of
center
eliminates
treble,
to the
right
of center
increases
treble.
BASS
(6)
(e)
The
Bass Control
is also
of the
cut
and boost
type.
Flat
(or
normal)
is straight
up. To
the
left
of center
cuts
bass,
to the
right
of center
boosts.
GROUND
REVERSE
(10)
Under
some conditions,
the
ground
reverse
switch
can reduce
or eliminate
a
persistant
hum
or click in
the
strings.
Set
the switch in
whichever
position
reduces
or eliminates
the
oroblem.
POWER
OFF/ON
(11)
This
turns the
whole
system
on
(see
hook-up
procedure).
lf
everything
is
working,
there
might
be
a loud
thump
when
you
turn the amp
on. DoN'T
pANlc.
This is normal.
