INSTALLATION
The
KRS-IA
is designed
to be set
up with
the
two
preamp
chassis
sitting
on top
of the two
power
supplies.
Before
proceeding
with
the final
installation
please
read
the
Phono
Section
Set Up and
C.D.
Section
Set Up portions
of the
manual
as they
involve
removal
of the
preamp
top covers.
This
is much
easier
to accomplish
before
the entire
preamp
is in place.
After
completing
set
up of the Phono
and
C.D.
sections
place
the
four
chassis
where
they
will
be perma-
nently.
Connect
the two
DC cables
between
the
eight
pin
connectors
on the
supplies
and the
preamps.
The AC cables
can
now be connected
between
the
supplies
and
the AC mains.
You
can
now proceed
with
connection
of the
various
source
components
in your
system.
The
rear
panel
inputs
follow,
from
left
to right
as viewed
from
the front,
the assignment
on the "Select"
switch
from
phono
to tuner,
etc.
Typically
the top
chassis
is used
for
the left
channel,
the
bottom
one for
the right
channel.
After
the inputs
are
the Record
Outputs.
Last
are
two sets
of Main
Outputs.
These
operate
in unison
and
are
provided
as a convenience
for routing
to two
inde-
pendant
systems.
