repeat-
edly until the name of the source is shown in
the Main Information Display or by pressing
the desired system on button on the remote
control. Please take the time to first associate
physical Input jacks to source names, then
press the Power button to place the amplifier
in standby to have it save your preferences.

With the Input setup, you may adjust bass and
Treble as well as balance if you have not already
done this during the setup process.
With the eQ Preset you can select one, two or
three stages of equalization, if you did already
perform the ezset / eQ setup automated adjusting

Making a recording
You may record any source to tape or to CD-R or
to both simultaneously. You may also connect a
second tape deck to the CDR inputs and outputs
to record from tape to tape (in either direction).
To select the desired source for recording (this
can be a different source than the one being
listened to), press the Record out button, fol-
lowed by the source selector up or down button
on the front panel repeatedly until the indica-
tor for the name of the source to be recorded
is shown in the Main Information Display. all
Input signals, digital or analog, are available for
recording in both digital and analog form. This
means that if you wish to copy a vinyl record to a
digital recorder, you simply start vinyl play, select
Phono as Record source and begin recording on
your digital recorder. The built-in analog/digital
converters transform the analog Phono signal to
digital form. The reverse is also possible: if you
have connected a cd player to the HK 990 with
a digital cable, its signal is available from the
analog recording outputs as well as the digital
outputs.
NOTE:
The record output signal is taken directly
from the program source and is unaffected by the
Volume, bass, Treble or balance controls.
Important Notes:
”Record source” can be selected on the front
•
panel only, not from the remote control.
3-head cassette decks with monitoring func-
•
tion can be connected to ”Tape” or ”CDR”
connectors too, but their monitoring function
cannot be used.
always turn the HK 990 to standby with the
•
Power button before unplugging the Power
Cord (or before switching off an external
multi-plug). This saves your current setup in
the memory, in addition to safely switching off
the power amplifier section of the HK 990.
