USING THE PRE OUT/MAIN IN TERMINALS
These terminak are used
to
connect
compon€nts
for
more
sophisticated
audio systems.
Ahhough the
JR.
5400 is an integrated receiver,
hs
preamplifien
and main
amplifiers
can be separated
for
use in
complex
systems.
The illustration
shows a
multi{hannel amplifier
system
in which the output from the

is
oassed
throuoh
a
muhi-channel
filter
which splits
the

into
three frequency zones
for
