(HK6950R only- While it is in the "On" position, the remote control can switch the unit between the "On" and "Standby" modes. The remote control is inactive when this switch is "Off". Note that this unit will draw a small amount of power when the unit is in the "Off" mode.) Power Indicator HK6850 - This indicator is illuminated in green when the power switch is "On" and is not illuminated when the power switch is "Off'. HK6950R - This indicator is illuminated in green when the power switch is pressed "On" and is not illuminated when the power switch is "Off'. While the power switch is depressed, this indicator is illuminated in amber when the unit is switched off by remote control, indicating the "Standby" mode. PROTECT light This light indicates that the protection circuitry of your amplifier is engaged. The light will come on 3 0 under two circumstances: • When you turn the unit on. As the unit prepares itself for operation, a muting circuit temporarily prevents pops or other noise from reaching your speakers. When the unit is ready for operation (in approximately 10 seconds), the light will go off. • When the unit detects a problem. This light will come on if your speakers wires are touching, causing a short circuit, or if your amplifier overheats. In the case of overheating, a thermal sensor will shut down the unit before damage can occur. Depending on the cause and extent of the overheating, the unit may take some time to cool down, and the protection circuit will remain in operation until the unit is cool enough to operate safely. In the case of a short circuit in the speaker wires, the protection circuitry will attempt to reset itself every 10 seconds, and you may hear a slight click as it does so. The protection circuit will remain in operation until the condition is corrected. 0 HEADPHONE jack Stereo headphones with a standard 1/4" plug can be connected to this jack. You can listen to headphones regardless of whether your speakers are playing. To listen to headphones only, turn the speaker selector to "OFF." ID PHASE CORRECT LOUDNESS At low volume levels, your ear is less sensitive to very low bass frequencies than it is at normal listening levels. The loudness button provides a special equalization curve that boosts low frequencies. The loudness button is useful for restoring full frequency balance at low volume levels, and can also be used to improve the bass response of small bookshelf speakers. The indicator light will be lit when PHASE CORRECT LOUDNESS is on. 43 SUBSONIC filter Warped records and turntable resonance can generate sub-audible frequencies that can cause your speaker's woofer cones to visibly flutter. This very low frequency noise, while inaudible, can rob power from your amplifier, can cause feedback through your turntable, can cause intermodulation distortion at audible frequencies, and can actually damage your woofers if the movement is violent enough.

PROTECT
light
This
light
indicates
that
the
protection
circuitry
of
your
amplifier
is
engaged.
The
light
will
come
on
3
0
under
two
circumstances:
When
you
turn
the
unit
on.
As
the
unit
prepares
itself
for
operation,
a
muting
circuit
temporarily
prevents
pops
or
other
noise
from
reaching
your
speakers.
When
the
unit
is
ready
for
operation
(in
approximately
10
seconds),
the
light
will
go
off.
When
the
unit
detects
a
problem.
This
light
will
come
on
if
your
speakers
wires
are
touching,
causing
a
short
circuit,
or
if
your
amplifier
overheats.
In
the
case
of
overheating,
a
thermal
sensor
will
shut
down
the
unit
before
damage
can
occur.
Depending
on
the
cause
and
extent
of
the
overheating,
the
unit
may
take
some
time
to
cool
down,
and
the
protection
circuit
will
remain
in
operation
until
the
unit
is
cool
enough
to
operate
safely.
In
the
case
of
a
short
circuit
in
the
speaker
wires,
the
protection
circuitry
will
attempt
to
reset
itself
every
10
seconds,
and
you
may
hear
a
slight
click
as
it
does
so.
The
protection
circuit
will
remain
in
operation
until
the
condition
is
corrected.

HEADPHONE
jack
Stereo
headphones
with
a
standard
1/4"
plug
can
be
connected
to
this
jack.
You
can
listen
to
headphones
regardless
of
whether
your
speakers
are
playing.
To
listen
to
headphones
only,
turn
the
speaker
selector
to

ID
PHASE
CORRECT
LOUDNESS
At
low
volume
levels,
your
ear
is
less
sensitive
to
very
low
bass
frequencies
than
it
is
at
normal
listening
levels.
The
loudness
button
provides
a
special
equali-
zation
curve
that
boosts
low
frequencies.
The
loudness
button
is
useful
for
restoring
full
frequency
balance
at
low
volume
levels,
and
can
also
be
used
to
improve
the
bass
response
of
small
bookshelf
speakers.
The
indicator
light
will
be
lit
when
PHASE
CORRECT
LOUDNESS
is
on.
43
SUBSONIC
filter
Warped
records
and
turntable
resonance
can
generate
sub
-audible
frequencies
that
can
cause
your
speaker's
woofer
cones
to
visibly
fl
utter.
This
very
low
frequency
noise,
while
inaudible,
can
rob
power
from
your
amplifier,
can
cause
feedback
through
your
turntable,
can
cause
intermodulation
distortion
at
audible
frequencies,
and
can
actually
damage
your
woofers
if
the
movement
is
violent
enough.
