Harman Kardon hk990Vxi - Page 8

Don’t press this button when no external processor has been
connected to the hk880Vxi/hk990Vxi. Doing so results in
silence. If you have added a signal processor, also remember
to turn it on before pressing EXTERNAL PROCESSOR (14).
To the right of the MONO button is the MOVING MAGNET/
MOVING COIL CARTRIDGE input selector (14). The normal (OUT)
position selects the hk990Vxi’s input for regular moving
magnet cartridges and high output moving coil cartridges
which generate at least 2.2mV. The “IN” position switches to
the moving coil inputs and engages a special MC step-up
amplifier stage.
Note that you can connect both MM and MC cartridge inputs
to the hk990Vxi and use this selector button to switch between
them.
At the top left hand side of your receiver are two LED’s. HIGH
CURRENT and HIGH VOLTAGE (16) refer to the mode of operation
to which the hk880Vxi/hk990Vxi is currently set. This is
covered in the HOOK-UP section farther on in this manual.
The FM/AM PRESET MEMORY section (17) is used to set and
recall up to 12 FM and 6 AM stations. How can you select 18
stations with just 6 buttons.
At the lower right of the numbered preset buttons is a selection
button marked FM/AM (18). This selector cycles the operation
of the presets from FM 1 (the first 6 FM presets) to FM 2 (the
second 6 FM presets) to AM and then back to FM 1, depending
on how many times you press it. In each case, an appropriate
indicator lights up in the tuner section display next to the
selector button.
Above the FM/AM selector is a MEMORY button (19) which is
used to enter station memory presets. You do not need to use
all of the presets. Full instructions on entering memory presets
are in the Operation section of this manual.
Next to the FM/AM PRESET MEMORY section, is the
hk880Vxi/hk990Vxi’s LCD display panel. First are indicators
for the 3 groups of presets: FM 1, FM 2 and AM.
Next is the digital station frequency display. Depending on
whether an FM or AM station has been selected, it will read in
MHz (FM) or kHz (AM).
HK990Vxi ONLY — When Active Tracking circuitry is engaged,
an ACTIVE TRACKING indicator will light above the MHz/
kHz indicators.
Next on both the hk880Vxi and hk990Vxi tuner panel are an
FM stereo indicator and a digital display that tells you which
preset has been selected. Note that it also displays the second
set of FM presets as 1-6.
The large square TUNING buttons and the smaller one to their
right marked seek work together to select stations from FM and
AM broadcast bands. The seek button determines the action of
the large UP and DOWN TUNING buttons.
When the seek button is pushed, the receiver’s tuner circuitry
is in SEEK mode and the word “SEEK” will light up in the
LCD display area. Pressing either the UP or DOWN TUNING
buttons causes the tuner to scan across the broadcast band
“seeking” (and stopping) at the next strong signal. In the
SEEK mode, the scanning circuit will automatically jump to
the opposite end of the tuning band and begin searching again.
When the seek button is pushed again (MANUAL), the UP and
DOWN TUNING buttons function much like a tuning knob on
a simple radio. Pushing UP moves “up” the FM or AM
broadcast bands; DOWN tunes “down”. This allows you to
locate weak or adjacent stations which might be skipped over
while in the SEEK mode.
When you reach the top or bottom limit of either band, you
must press the opposite direction button to begin moving back
across the broadcast band.
