O Power Switch
Press this switch to turn the unit “On”. Press it again
to turn it “Off”. (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 illumi-
nated 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
under two circumstances:
e 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
“OFF.”
@ 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.
Q 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. The subsonic filter
