Installation and Connections

Audio and Speaker Connections

After unpacking the unit and placing it on a solid surface capable of supporting its weight, you will need to make the connections to your audio and video equipment. These steps need to be done only when the receiver is first installed or when a change is made to the input source equipment.

Audio Equipment Connections

We recommend that you use high-quality inter- connect cables when making connections to source equipment and recorders to preserve the quality of the signals.

When making connections to audio source equipment or speakers it is always a good prac- tice to unplug the unit from the AC wall outlet. This prevents any possibility of accidentally send- ing audio or transient signals to the speakers that may damage them.

1. Connect the analog output of a CD player to the CD inputs .

NOTE: When the CD player has both fixed and variable audio outputs, it is best to use the fixed output unless you find that the input to the receiver is so low that the sound is noisy, or so high that the signal is distorted.

2.Connect the Play/Out jacks of a cassette deck, CDR, MD or other audio recorder to the Tape

Monitor Play jacks . Connect the Record/In jacks on the recorder to the Tape Monitor

Rec. Out jacks on the HK 3380. When the tape deck connected to these jacks is a three- head unit or has off-head playback, it will be possible to monitor the output of the source being recorded.

3.Connect the audio and/or video outputs of a second audio recorder, VCR or other line-level audio device to the Video 1 Audio/Video Input Jacks , If a recorder is used, connect

its Rec/In jacks to the matching outputs

4.The audio output of any electronics product with a line-level output, such as a TV set, satel- lite receiver or DVD, may be connected to the

Aux jacks . Video 2 and Video 3

Audio/Video inputs

NOTE: In order to view the video signals of any devices connected to the Video 1 , Video 2


or Video 3	Video Inputs, you will need
to connect the Video Monitor Output		jack

to the composite video input of your TV or other video display device.

5.Connect the outputs of a turntable with a moving magnet cartridge to the Phono inputs

. To insure that the phono playback is noise- free, connect the ground wire from the tone-arm

to the Phono Ground terminal .

6.Assemble the AM Loop Antenna supplied with the unit as shown below. Connect it to the AM

screw terminals	.

7. Connect an FM antenna to the FM Antenna connection . The FM antenna may be an external roof antenna, an inside powered or wire lead antenna or a connection from a cable sys- tem. Note that if the antenna or connection uses 300-ohm twin-lead cable, you must use the

300-ohm-to-75-ohm adapter supplied with the unit to make the connection.

8.If you wish to use external processing equip- ment, such as an equalizer, you may connect the device to the preamp-out and main-in jacks by removing the Preamp-Out/Main-In Jumper

Pins and connecting the Preamp Out jacks to the inputs of the external device, and the outputs of the device to the Main In jacks.

Alternatively, you may connect the external device to the Tape Monitor Loop. Connect the

Tape Monitor Record/Out jacks to the

inputs of the external device, and connect the outputs of the device to the Tape Monitor Play/In jacks .

Speaker and Output Connections Regardless of the brand of cable selected, we recommend that you use a cable constructed of fine, multistrand copper with an area of min.

2 mm2.

Cable with 1.5 mm2 may be used for short runs of less than 3 meters. We do not recommend that you use cables with an area of 0.8 mm2 or smaller due to the power loss and degradation in performance that will occur.

Questions about running cables inside walls should be referred to an installer or a licensed electrical contractor who is familiar with applica- ble local building codes in your area.

When connecting wires to the speakers, be certain to observe proper polarity. Remember to connect the “negative” or “black” wire to the same terminal on the receiver and the speaker. Similarly, the “positive” or “red” wire should be connected to the like terminals on the HK 3380 and speaker.

We also recommend that the length of cable used to connect speaker pairs be identical. For example, use the same length piece of cable to connect the Speaker 1 left and right or Speaker 2 left and right speakers, even if the speakers are a different distance from the

HK 3380.

NOTE: While most speaker manufacturers adhere to an industry convention of using black terminals for negative and red ones for positive, some manufacturers may vary from this configu- ration. To assure proper phase, and optimal per- formance, consult the identification plate on your speaker, or the speaker’s manual to verify polarity.

If you do not know the polarity of your speaker, assure that both speakers are connected with the same polarity, i.e. speaker wires or terminals with any marking should be connected to the red speaker terminals on the HK 3380, the oth- ers to the black ones (see connections below).

Connect the speakers using the following steps:

1.Connect the main speakers to the Speaker 1 terminals .

2.Connect a second set of speakers, or speakers that are in a second room location, to the

Speaker 2 terminals .

3.When an optional, powered subwoofer (not the aktive Sub of a Sub/Sat-System) is used, con- nect the outputs of the left and right Sub-

woofer Out jacks to the line-level inputs of the subwoofer. When the subwoofer’s amplifier has stereo inputs, run interconnects from both jacks. When the subwoofer has a mono input only, use the bottom output jack for the connec- tion. When a separate passive subwoofer is used, these connections will be made to the optional amplifier that powers the subwoofer.

If a Sub/Sat system is used (aktive or passive),

connect the Speaker 1 terminals to the speaker-level inputs on the subwoofer, and then connect the speaker-level outputs on the sub- woofer to your main left and right speakers, fol- lowing the instructions provided with the sub- woofer.
