The best A/V sources are laser disc or home satellite followed by off-the-air television, cable or VHS HiFi. A 31"-35" direct view - Harman Kardon AVP-1 | Owners Manual - Page 4
MEM MEM I speakers immediately beside a small screen usually reduces stereo separation to unacceptable levels. Some experimentation may be in order, but as a rule of thumb, try to place the UR front speakers no more than 18" to 24" from the sides of the screen. Try to avoid placing the L/R - Harman Kardon AVP-1 | Owners Manual - Page 5
with the indiscriminate use of sound-absorbing products, but even this technique has its pitfalls. All of these common acoustical problems will be addressed in this section. Once again, these techniques are not necessary for a successful Home THX Audio System installation. Rather, they are provided - Harman Kardon AVP-1 | Owners Manual - Page 6
IN III NNE II III III NI I A variation of this method is especially helpful in rooms which are already fairly "dead" acoustically. Rather than using absorptive material in rooms like these, try using diffusion instead. Commercially built diffusers are available but large bookcases and - Harman Kardon AVP-1 | Owners Manual - Page 7
ineffective at lower frequencies. See the discussion on Standing Waves for more information about treating environments with low frequency response problems. EXCESSIVE USE OF ABSORPTIVE MATERIALS People are sometimes tempted to go overboard with absorptive material once they discover how powerful - Harman Kardon AVP-1 | Owners Manual - Page 8

In those relatively rare cases where you have the luxury of building the home theater room from scratch, consider using non-parallel surfaces in the construction of the room. A difference of as - Harman Kardon AVP-1 | Owners Manual - Page 9
modes" - that is, the frequencies at which the room tends to vibrate of its own accord. These resonances lead to uneven frequency response, the greatest problems being in the 60-150 Hz range for a typical domestic living room (at lower frequencies in larger rooms). Unfortunately, there is no way to - Harman Kardon AVP-1 | Owners Manual - Page 10
of fiberglass would be required in order to damp everything down to 100 Hz - not very practical. Standing wave energy tends to be ROOM EQUALIZATION If a room exhibits severe standing wave problems, the best solution is to know your limitations: services of an acoustician when you need them. 9 - Harman Kardon AVP-1 | Owners Manual - Page 11
SUGGESTED DEMONSTRATION TITLES The THX disc, WOW!, features a number of sections with exciting and entertaining demonstrations of the various aspects of motion picture sound tracks including low frequency response, dynamics, and surround effects. There are also many other discs which will provide
