kde Posted June 22, 2006 Share Posted June 22, 2006 I purchased the digital SPL meter from Radio Shack, but have not taken it out of the box yet. I am planning to "play" with the device alongside the Avia cd and possibly the (Riva - forget the name) cd. I have read about the variances and inaccuracies in the models, but for $50 -- it's probably worth a shot right? So, do I keep the digital or return it and get the standard?

rcarlton Posted June 22, 2006 Share Posted June 22, 2006 I have the standard. Works great. Go to Home Theater for correction tables and a wonderful free program that allows you to utilize the meter to its potential. Quote Link to comment Share on other sites More sharing options...
Buckeye_Nut Posted June 23, 2006 Share Posted June 23, 2006 Heck, most people probably cant take accurate measurements with the analog version. Quote Link to comment Share on other sites More sharing options...

chevellerh Posted June 25, 2006 Share Posted June 25, 2006 I also recently bought a cheapo spl meter (digital , not from rs), I dont really know how accurate it is though, may be a dumb question but how would you be able to tell? Fun to play around with anyway Quote Link to comment Share on other sites More sharing options...
Jay481985 Posted June 25, 2006 Share Posted June 25, 2006 by playing testtones you can chart the speakers. usually lows are off alot. Also digital and anlog are about the same. The analog has one thing over the fact that the digital rounds to the nearest dB while the analog you can guesstimate about how much the dB is between two numbers. Again though the dB meter is probably +- 1 dB its really not that important Quote Link to comment Share on other sites More sharing options...
kde Posted June 25, 2006 Author Share Posted June 25, 2006 Maybe I am having little patience with the cd, but it is difficult to follow when it is based on a 5.1 set up versus a 7.2. Is the basic goal to get all the speakers at the same db level? For example, if I get all speakers at 75db -- is my system calibrated?

coreyc Posted June 26, 2006 Share Posted June 26, 2006 Is the basic goal to get all the speakers at the same db level? For example, if I get all speakers at 75db -- is my system calibrated? There's 2 things you can do with an SPL meter, and that's the first: get all your speakers to play at the same level when you run your receiver's test pink noise thru them. The second thing you can do is to see how your system reproduces the frequency spectrum, by playing test tones. Use your sub-woofer level & tone controles to get the response as flat as you can. If you want to go further, look into getting a parametric equlizer for your sub, and modifing the acoustics of your room. Quote Link to comment Share on other sites More sharing options...
