leslie Posted February 20, 2002 Share Posted February 20, 2002 In my Kenwood receiver you set the sound of the main speakers to a certain dB level (-10dB to +10dB), same with the Subwoofer and the rest of the speakers. For example, if the L and R speakers are set to +2dB and the subwoofer to +10, does it mean that the receiver always output 400 percent more signal to the subwoofer (as compared to the L/R speakers in this example) everytime the volume is changed? I'm just curious (and ignorant). This message has been edited by leslie on 02-20-2002 at 12:50 PM Quote Link to comment Share on other sites More sharing options...
Guest BobG Posted February 20, 2002 Share Posted February 20, 2002 The balance you establish between mains, center, rears and sub will be maintained as you change volume. Quote Link to comment Share on other sites More sharing options...
Ray Garrison Posted February 20, 2002 Share Posted February 20, 2002 Uh, probably doesn't mean anything in an "absolute" way. the +/- adjustment allows you to raise or lower the gain of the various speakers compared to what the factory considers the default value to be. You have no way of knowing how the outputs of the main and subwoofer channels were set relative to each other. Also note that scales labeled in "dB" on most equipment aren't really very accurate - the +8dB setting you're using on your subwoofer might be exactly 8dB higher, but it could just as easily be something completely different, either much more or less. Just set the volume so it the sub to main balance sounds correct to you. ------------------ Music is art Audio is engineering Ray's Music System Quote Link to comment Share on other sites More sharing options...
avman Posted February 20, 2002 Share Posted February 20, 2002 use an spl meter ($40 at radio shack) to be sure you actually have the speakers balanced. i've 'balanced' systems for 8+ years by EAR and when i used a spl meter i was surprised at how far off i was. use 'c' weighting/fast response if you also want to include the sub.avman. ------------------ 1-pair klf 30's c-7 center ksps-6 surrounds RSW-15 in the house!! sony strda-777ES receiver upgraded to v.2.02 including virtual matrix 6.1 sony playstation 2 sony dvpnc 650-v 5-disc dvd/cd/SACD changer dishnetwork model 7200 dishplayer satellite receiver/digital bitstream recorder sony kv36xbr450 high-definition 4:3 tv sharp xv-z1u lcd projector w/84" 4:3 sharp screen Bello'international Italian-made a/v furniture panamax max dbs+5 surge protector/power conditioner monster cable and nxg interconnects/12 gua.speaker wire KLIPSCH-So Good It Hz!

HornEd Posted February 20, 2002 Share Posted February 20, 2002 Really Avman? In my experience, setting all the speakers except the sub is best done in "C" weighting and "SLOW" response... and set the sub by "ear and rear"... that is, I sit in my leather LazyBoy and listen to pink noise until my leather vibrates my rear and the sound fill my ear.

avman Posted February 20, 2002 Share Posted February 20, 2002 o.k.-slow response IS better to set sound levels, fast is for peak spl, slow is for 'average' speaker level.'a' weighting excludes frequencies below ?500Hz? btw-i used the spl meter at home as a 'standard' to see how well i'd done by ear (and rear ) the rears needed about 2.5dB more, and the center about 1.5.still playin'w/the sub output, and still change it for different program material. HornEd..tinkered w/the 'phantom' DEFINITELY noticed a change vs. the c-7, more trials to follow...you say a klf-hE-center will fit...hmmm...avman. ------------------ 1-pair klf 30's c-7 center ksps-6 surrounds RSW-15 in the house!! sony strda-777ES receiver upgraded to v.2.02 including virtual matrix 6.1 sony playstation 2 sony dvpnc 650-v 5-disc dvd/cd/SACD changer dishnetwork model 7200 dishplayer satellite receiver/digital bitstream recorder sony kv36xbr450 high-definition 4:3 tv sharp xv-z1u lcd projector w/84" 4:3 sharp screen Bello'international Italian-made a/v furniture panamax max dbs+5 surge protector/power conditioner monster cable and nxg interconnects/12 gua.speaker wire KLIPSCH-So Good It Hz!

leslie Posted February 20, 2002 Author Share Posted February 20, 2002 Hey Avman, etc., I haven't really seen what that SPL meter looks like (I'll stop by at Radio Shock on my way home). How do you use it? Do I have to play some music then measure the sound level on each speaker using the SPL meter? What do you mean by unbalanced speakers? Does it have to be always balanced? I would really appreciate if you can explain to me (in idiot-proof manner) how the process is done before I'll stop by at Radio Shock. Thanks.
