NOTES
ON INSTALLATION
Be sure
the
volume
controls
are
fully
counterclockwise
before
making
connections
to the KRS-IA;
also,
the power
amplifier(s)
should
be off
while
making
connections.
Place
all power
amps,
C.D.
players
or other
power
supplies
a
reasonable
distance
from
the KRS-IA
as they
might
induce
hum
into
the phono
section.
Our
custom
RCA
connectors
are
made
to very
exact
standards.
Connectors
of lesser
quality
can
damage
them
or function
improperly.
Please
check
with
your
dealer
or the
factory
as you could
cause
damage
to
your
system
or jeopardize
your
warranty.
PHONO
SECTION
SET UP
The
KRS-IA
is shipped
with
the phono
section
set
up for
a
moving
coil
cartridge
and
loaded
to 100
ohms.
The
loading
can be changed
with
a set of internal
switches.
To access
these
switches
the
top
cover
of the
preamps
must
be removed
with
the
supplied
allen
driver.
The phono
section
is located
on the
left
side
of the
unit,
as viewed
from
the
front.
In
the middle
rear
of the phono
PC board,
which
is mounted
on
standoffs,
there
is an 8 position
switch.
