CONNECTIONS

Connections

Connecting Other Components

Make sure your amplifier and other 1.

components are turned off.

Connect each component's Output/Play 2.

jacks to the corresponding Input jacks on the

back of your amplifier and, if available, the

component’s Input/Record jacks to the Output

jacks of the HK 990. Use the white, black or

gray plugs to connect Left channel jacks; use

the red plugs for Right channel jacks.

Wired Remote Control

To control your amplifier with an external infra-

red remote sensor, connect the wire from the

remote sensor to the REMOTE IN jack on the

back panel. Or, if another stereo component has

a built-in infrared remote sensor and a Remote

Output jack, it may be possible to connect this

jack to the REMOTE IN jack of your amplifier. All

Harman Kardon products with »Remote In« and

»Remote Out« jacks are com pa tible with one

another, except for the Citation 22, 24 and 25.

Other manu fac turers' remote sensors and com-

ponents may not be compatible, but it will not

hurt to experiment. A second wire may be used

to connect your amplifier's REMOTE OUT jack to

the Remote Input of another stereo component.

Continue this process to include additional

components (if compatible).

Connecting Speakers

1. For best performance, use high quality speaker

cables. However, ordinary copper wire can be

used if the gauge meets the following require-

ments:

Wire Min.

Length Diameter

Up to 2.5 meter 1 mm

Up to 4 meter 1.25 mm

Up to 6 meter 1.6 mm

Above 6 meter 2-2.5 mm

2. Avoid rolling excess wire with or near signal

interconnects.

IMPORTANT: When connecting two pairs of

speakers, determine the impedance of each pair

by looking on the back of the speakers, in your

owner's manual, or by contacting your dealer or

manufacturer.

You can listen to two pairs of speakers at

the same time ONLY if the impedance of

EACH speaker is NOT LESS THAN 8 Ohms.

WARNING: Do not play sets of speakers

simultaneously except as recommended above.

Amplifier may overheat.

AC Power

Plug the cord into a 230 VAC wall socket.

Power indicator will light up to indicate power

ON. To completely disconnect the power input,

the main plug must be disconnected from the

mains.
