Input
–
Standard
RCA

Level/Output
Control
–
This
rotary
dial
controls
the
output
level
of
the
UPA
‐
2.
This
is
recommended
for
use
when
the
output
level
of
the
UPA
‐
2
(32db)
exceeds
the
output
level
of
other
amplifiers
being
used
in
the
same
system.
Example:
You
are
using
the
UPA
‐
2
to
drive
your
main
left
and
right
speakers,
and
letting
an
AV
receiver
power
the
rest
of
your
setup.
The
output
of
the
UPA
‐
2
is
much
higher
than
the
receiver,
causing
the
system
to
sound
out
of
balance.
Use
the
Level
control
to
adjust
for
this
by
turning
it
counterclockwise
until
your
system
sounds
well
integrated.
