SECTION 2: RCA Input Amps
INPUT SECTION:
It
may
seem
unusual
to
find
4
RCA
inputs
on
a
2

amplifier,
but
that
is
just
what
you
will
find
when
you
inspect
the
ADCOM
GFA-4302
or
GFA-

amplifiers.
Channel

is
the

is
the
“RIGHT”.
The

on
the
left
side
are
the

and
the

on
the
right
side
are
the
(-)
negative
inputs.
If
you
wish
to
run
these
amplifiers
in
the
Balanced

it
is
strongly
suggested
that
an

handle this installation!
