User manual HARMAN KARDON HK380I

[. . . ] While sophisticated systems are hard at work within the HK380I to make all of this happen, hookup and operation are simple. Color-keyed connections and a comprehensive remote control make the HK380I easy to use. To obtain maximum enjoyment from your new receiver, we urge you to take a few minutes to read through this manual. This will ensure that connections to speakers, source playback units and other external devices are made properly. [. . . ] 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 interconnect 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 practice to unplug the unit from the AC wall outlet. This prevents any possibility of accidentally sending audio or transient signals to the speakers that may damage them. 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. Connect the Play/Out jacks of a cassette deck, CDR, MD or other audio recorder to the Tape Monitor In jacks ª. Connect the Record/In jacks on the recorder to the Tape Monitor Out jacks , on the HK380I. 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. Connect the output of a second audio recorder, CDR, VCR or other line-level audio device to the Tape 2 Play/In jacks /. If a recorder is used, connect its Rec/In jacks to the matching Tape 2 Record outputs ¤. The FM antenna may be an external roof antenna, an inside powered or wire lead antenna or a connection from a cable TV system. 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. Speaker and Output Connections To ensure that all the audio signals are carried to your speakers without loss of clarity or resolution, we suggest that you use high-quality speaker cable. Many brands of cable are available, and the choice of cable may be influenced by the distance between your speakers and the receiver, the type of speakers you use, personal preferences and other factors. Your dealer or installer is a valuable resource for help in selecting the proper cable. Regardless of the brand of cable selected, we recommend that you use a cable constructed of fine, multistrand copper with a gauge of AWG14 or smaller. Remember that in specifying cable, the lower the number, the thicker the cable. Cable with a gauge of 16 may be used for short runs of less than ten feet. We do not recommend that you use cables with an AWG equivalent of 18 or higher due to the power loss and degradation in performance that will occur. Cables that are run inside walls should have the appropriate markings to indicate listing with UL, CSA or other appropriate testing agency standards. Questions about running cables inside walls should be referred to your installer or a licensed electrical contractor who is familiar with the NEC and/or the applicable local building codes in your area. 12 INSTALLATION AND CONNECTIONS Installation and Connections System and Power Connections The HK380I is designed for flexible use with external control components and power amplifiers. [. . . ] If the system still does not respond, it may be necessary to perform a complete reset. To reset the system, first turn the HK380I off by pressing the Main Power Switch 1 and then releasing it so that it extends out beyond the front panel and the word "OFF" is visible in red at the top of the switch. Next, press and hold the T-Mon and CD Input Selector buttons 9 # on the front panel ONLY. While holding these buttons in, press the Main Power Switch 1 in until it latches, so that the button is flush with the front panel. [. . . ]
