Troubleshooting

OPERATING INSTRUCTIONS

Listening to your CD player, tape

deck, tuner or other source

1. Press the Power switch 1 to turn on the

amplifier. The power indicator lights white and

the protection circuitry checks for short circuit

or other problems for a few seconds before

sound output.

2. Press ”Speaker 1” to hear loudspeakers

connected to the rear Speakers 1 terminals.

Press ”Speaker 2” to hear loudspeakers

connected to the rear Speakers 2 terminals.

Press both to hear both speaker pairs at once.

To listen to headphones only, press to turn off

any active speaker pair.

3. Select desired source for listening by pressing

the front panel Source up or down 4 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.

4. Begin playing the desired source.

5. Adjust the Volume control to the desired level.

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

process as described above.

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.

This unit is designed for trouble-free operation; most problems users encounter are due to operating errors. So if you have a problem, first check this list for a

possible solution. If the problem persists, consult your authorized HarmanKardon service center.
