Guest Posted January 25, 2010 Report Share Posted January 25, 2010 depends. AC's have that gain knob for god knows why (i'd like to know if anyone does) so the only way to know how far off one meter is from a TL, you gotta have em side by side Link to comment Share on other sites More sharing options...
PUNKYOU007 Posted January 25, 2010 Author Report Share Posted January 25, 2010 so gay, i gotta find out where they put the mic too. Doethepaperboy "Bars of Pain" Doethepaperboy "Hero Remix" C.

tristan560 Posted January 26, 2010 Report Share Posted January 26, 2010 Also depends on what AC they are using. I put up a 162 with the AC. But i know damn well thats not the case. Still need to get on the TL with my new setup. <u>99 Jimmy SLT 4WD</u> Systemless. <u>99 Grand Prix GTP</u> DC XL 12 on 1.5k tuned lowwwwww.

jhmeg2 Posted February 15, 2010 Report Share Posted February 15, 2010 The AC is also used as a tool to tune with and test RTA. Thats why it has knobs... there is more to car audio than going boom. Actually, is rare, but I heard that some people actually listen to muuuusic in thier cars. Crazy right!!!? LOL I think the AC is about 3dB off from the TL, but I think the AC3056 has a new sensor and is a lot closer that it used to be. I prefer to tune only with the AC unit, and use it to find Res. Freq. Others wise if I were to get back into SPL, I would get meeterd on the TL. ////Alpine, Eclipse, Load Boss, Pheonix Gold, MB Quart,Digital Desings, Memphis, Stinger, Periphial, MTX, Visualogic Link to comment Share on other sites More sharing options...

noiseycricket Posted February 15, 2010 Report Share Posted February 15, 2010 our Ac is 2 to 3 db off, and our mic is place on the windshield where a TL mic would normally be 4 I.A.

raytard Posted February 15, 2010 Report Share Posted February 15, 2010 ours is 9db off competition wise, an AC mic is VERY accurate, everyone would have the same 9db boost. so if you were 1.3db louder on an ac, youre 1.3 louder on a tl. tl is pre-calibrated so unit to unit, show to show, your score is going to be the same. AC's are all calibrated slightly different, so a 150 here is a 145 there and a 152 somewhere else.

For example my Team's TL reads about .3db lower than the TL that the promoter of NSPL uses and about .7db lower than a local SC organization. I've also seen this to be true from show to show in Ohio where different TL's have been used since a different promoter was running the shows. I've never seen more than a db but it is still odd how they are completely different even when tested side by side, which has been done several times before. They can still fall out of calibration and need to be sent back every once and a while to Wayne Harris for recalibration. Usually when a vehicle over 170db is on the mic is when it will start to loose it's accuracy. 2013 VW Jetta GLI 2.0 Turbo 1 Sundown Audio SCV2000 1 Sundown Audio X15 V2 1 XS Power D3100 Audio Control LC6i Stock Deck 146.4 sealed on the dash at 37hz 2001 Focus ZX3: RETIRED Team Sundown Audio, Team XS Power, 2 time NSPL Car 3601-Up Champion, 2 time NSPL Car Hardcore ChampionHighest NSPL Scores to date:154.3db on the dash sealed at 46hz, 156.2db in the kick at 46hz155.2db unofficial on dash at 43hz Link to comment Share on other sites More sharing options...
