4. GGESTIONS We recommend that you not operate your speakers or subwoofer with the bass treble and loud ness controls set to full boost This will place undue strain on your electronics and speakers and could damage them The volume control setting on your preamplifier or stereo receiver is not a specific indication of the overall loudness level of the speakers The only important consideration is the loudness level at which the system can be played regardless of where the volume control is set Always turn down the volume control setting on your preamplifier or stereo when changing a cassette or CD or switching inputs to AM or FM operation Excessively loud transients clicks or popping sounds can damage the satellite speakers and possibly the subwoofer Whenever changing cables pulling plugs etc ALWAYS TURN OFF ALL EQUIPMENT includ ing the subwoofer This prevents transients from entering the speakers and prevents electrical energy from reaching you Keep all connections out of the reach of children HPS 250 Owners Manual 5 POSITION WITHIN A Room WILL STRONGLY INFLUENCE PERFORMANCE 6 HPS 250 Owners Manual POSITIONING Since the installation of a subwoofer is somewhat more complicated than installing full range speakers it is essential you read this section very carefully prior to connecting the subwoofer to your system Should you have questions relating to your installation it is advisable to call

10. either your dealer or Infinitys Customer Service Department for advice The performance of the subwoofer is directly related to its placement in the listening room and how you align the subwoofer with its satellite speakers Setting the volume of the subwoofer in relationship to the left and right speakers is also of critical importance because it is essential that the subwoofer integrates smoothly with the entire system Setting the subwoofers volume level too high will result in an overpowering boomy bass Setting the volume level too low will negate the effect of the subwoofer We recommend placing the HPS 250 subwoofer at least 2 to 3 feet away from a television or a computers disc drive system to prevent smearing the colors of the TV picture or erasing of the magnetic drive Here are several additional facts on installation that may prove useful It is generally believed by most audio authorities that low frequencies below 125Hz are nondirectional and therefore placement of a subwoofer within any listening room is not critical While in theory it is true that the larger wavelengths of extremely low frequencies are basically non directional the fact is that when installing a subwoofer within the limited confines of a room reflections standing waves and absorptions generated within the room will strongly influence the performance of any sub woofer system As a result specific location of the subwoofer becomes important
