User manual HARMAN KARDON HK680I

[. . . ] harman/kardon's audio heritage combined with continual research has provided the unique technologies included in the HK680I Audio System. These technologies include Vmax, a Harman International audio image-processing algorithm that seamlessly supports both two and four channel sound cards. This audio hologram creates a four speaker sound field from two speakers through the use of a head related transfer function when used with a four channel sound card. In addition, the algorithm provides enhanced stereo when used with a two channel sound card. [. . . ] A system on/off switch is also provided on the rear of the subwoofer unit. The system includes two desktop speakers and a subwoofer that can be placed either on the floor or on your desk. Both satellite speakers and the subwoofer are magnetically shielded to provide the greatest protection against computer monitor image distortion. file:///D|/HK680I/intro. htm (1 of 2)11/16/2004 3:52:48 AM Introduction:Using the speaker system: harman/kardon Champagne HK680I Audio System Back to Contents Page file:///D|/HK680I/intro. htm (2 of 2)11/16/2004 3:52:48 AM Setup: harman/kardon HK680I Audio System Back to Contents Page Setup: harman/kardon HK680I Audio System Unpacking the speakers · Connecting the speakers to your sound card · Placement of speakers Unpacking the speakers Carefully unpack your speaker system and identify all components: q q q Control/Right Satellite speaker Auxiliary/Left Satellite speaker Subwoofer with attached power and audio input cables Connect the speaker system as shown in the Connecting the speaker system to sound card illustrations.

The diagnostic test can also be used to test the rear speaker channel input by plugging in the black connector into the diagnostic jack on the rear of the subwoofer. (Test tone may sound different due to the surround characteristics of speaker system). When you have finished the test, unplug the cable from the `DIAG' jack and plug the audio cable back into the correct soundcard output jack. While the speaker system is in the diagnostic mode, the -/+ controls will control the volume of the diagnostic tone. If the test tone was heard from all speakers, your HK680I Audio System is working correctly. If not, see the troubleshooting section for detailed troubleshooting techniques. file:///D|/HK680I/usage. htm (4 of 5)11/16/2004 3:53:03 AM Using the speaker system: harman/kardon HK680I Audio System Back to top Back to Contents Page file:///D|/HK680I/usage. htm (5 of 5)11/16/2004 3:53:03 AM Diagnostics: harman/kardon Hk695 Audio System Back to Contents Page Diagnostics: harman/kardon HK680I Audio System In order to facilitate optimal system setup, a diagnostic system has been built in to the harman/ kardon HK680I Audio System.

Speaker system experiences radio frequency interference or picks up a radio station. The redundant rear (black) audio connector is not protected by the rubber cover and is touching the computer system Input cable may be picking up interference. Replace the rubber cover or otherwise insulate the rear audio connector so it cannot contact any metallic surfaces Wrap up excess input cable in order to make as short as possible. Purchase a ferrite clamp and attach over input cable. [. . . ]
