Features
Plenty
of
Clean
Power
TX-850:
68
watts
of
FTC
rated
power
per
channel
into
8
ohms
with
no
more
than
0.04%
total
harmonic
distortion.
(2
x
145
watts
dynamic
power
at
3
ohms)
TX-830:
58
watts
of
FTC
rated
power
per
channel
into
8
ohms
with
no
more
than
0.08%
total
harmonic
distortion.
(2
x
130
watts
dynamic
power
at
3
ohms)
These
tuner
amplifiers
are
designed
to
consistently
deliver
their
full
rated
power
even
into
jow
impedance
loads.
Discrete
Output
Stage
Instead
of
|C
power
amp
circuitry,
the
TX-850
and
TX-830
both
employ
a
discrete
output
stage
for
effortiess
drive
into
low
impedance
loads.
Low
distortion
linear
switching
and
the
high
quality
parts
used
throughout
are
proof
of
Onkyo’s
dedication
to
audio
excellence
not
merely
in
its
high
end
amps
but
across
the
board.
“CD
Direct”
Switch
This
switch
lets
the
user
bypass
the
tone
and
balance
controls
in
the
amplifier
when
listening
to
CD
(or
other
digital
audio
sources).
Since
noise
levels
in
digital
audio
are
extremely
low,
sending
and
switching
the
audio
signal
through
tone
and
balance
circuitry
is
often
unnecessary
and
may
even
adversely
alter
the
high
quality
digita!
signal.
APR
(Automatic
Precision
Reception)
System
Onkyo’s
exclusive
APR
precision
reception
system
lets
every
FM
broadcast
sound
its
best.
Intelligent
circuitry
monitors
the
signal
and
selects
the
optimum
settings
for
three
reception
modes
on
the
TX-830:
stereo/mono,
hi-blend
on/off
and
local/DX
mode.
On
the
TX-850
the
system
controls
the
noise
reduction
on/off
mode
as
well.
The
APR
system
settings
are
shown
by
indicators
on
the
front
panel.
