4. This unfortunate circumstance has become more common in recent years thanks to the explosion of IR controlled products in the home Fortunately the PAV allows you to use any of eight different sets of IR codes which are accessed by changing the IR ad dress used by the PAV If you change the IR address of your PAV your remote control will no longer operate the PAV until it is re taught all of the new codes Do not change this setting from its default value of 5 unless you must in order to solve a conflict If you run into an apparent IR conflict where pushing one button on a remote control affects something seemingly unrelated we suggest that you contact your dealer installer for assistance The numbers 0 through 7 refer to Philips RECS80 addresses a bit of engineering trivia your installer may need if your system is already using several of the available addresses including the one we normally use in the PAV 5 The remote tigger output on the rear panel of the PAV is normally used to auto matically tum the associated Proceed AMPs on and off with the PAV This is par ticularly convenient when the amplifiers are located at some distance from the PAV as may be the case when they are placed near the speakers for example In this application you can simply leave it in its default setting pulse If you need to turn on and off a power amplifier that does not include remote turn on capabilities the simplest solution is to use a p

8. SMALL OR NONE FOR YOUR C ENTER SPEAKER The PAV has the ability to remove bass information from the Center channel and split it out to the Left and Right speakers which are presumed to have better bass reproduction capabilities Informing the PAV that you have a large center speaker eg one which can reproduce bass will pass a full range signal on to the center channel Using the volume keys to toggle to small will split frequencies below 120 Hz out to the Left and Right chan nels Note that this function operates independently of whether or not you have a subwoofer For example THX certified LCR speakers operate to 80 Hz below which it is assumed you would have a THX certified subwoofer Be cause of this the LCRs are considered large speakers they can repro duce everything that would ever be required of them Phantom Center Channel Physical Setup Testing For Proper Phasing If your system does not include a center channel speaker choose none Doing so will place the PAV into a phantom center channel mode wherein the information which would normally be directed to the center speaker by the Pro Logic circuitry will instead be sent equally to both left and right speakers This process creates an illusion of a center channel speaker for those sitting on the centerline between Left and Right speakers Having a real center channel makes seating arrangements far more flexible than is the case with only a

11. Reverberation The Boundary Effect Room Acoustics The following information on room acoustics does not need to be considered in every installation Rather it is provided for those who plan a dedicated listening room or for those who feel they have a problematic room and therefore need ideas about how to improve their systems performance further Once again the value of your dealers experience should never be underesti mated Many installers have been involved in dozens or hundreds of home the ater installations similar to yours and have proven solutions to whatever problem you might be experiencing The information provided here is best used as a starting point for your discussions with your dealer In a perfect world your room would have no characteristic sound of its own no acoustical fingerprint The ideal room would be perfectly neutral and would not superimpose itself on the sound within it in any way After all any reverberation or ambient sound which the director wished people to hear will be recorded in the soundtrack And much of the inherent ambience in music recordings will normally be reproduced by the rear speakers using the stereo sunound mode where such ambience belongs Anything beyond this added by the room would be redundant and would actually detract from the realism In general then the ideal listening room will be somewhat more dead acoustically than the average living room This goal can be accompl
12. The list of equipment needed for a full home theater system based on the PAV is fairly straightforward The Proceed PAV At least six channels of amplification Left Center Right two Sur rounds and one or more Subwoofers Additional amplification with volume control and loudspeakers if a remote zone is to be used Alternatively this output may be used in conjunction with a third party multi room system Left Center and Right LCR front speakers with appropriate stands or mounting brackets One or more subwoofers required with THX speaker systems otherwise optional but recommended A pair of Surround speakers with appropriate stands or mounting brackets Assorted appropriate interconnecting cables speaker wires etc Of course you will also need at least one source and a display system The best consumer video sources in order of quality are Laserdisc Direct Broadcast Satellite link DBS DSS a good cable TV or antenna signal Super VHS tape Hi 8 mm videotape regular VHS videotape The light pollution created by some components can be significant and distract ing Ideally all equipment should be conveniently located for operation but any lights and other indicators should be out of your direct field of vision when viewing the television picture The various indicator lights though essential for proper operation can be distracting when listening to music or watching a movie While the PAVS displ
