Hi, I have been successfully using my calibrated mic with .frd file in REW for some years. It corrects for frequency response, but I assumed it doesn't correct for sensitivity / SPL. However, I recently came across a message in REW that I don't need to go through the sensitivity calibration...

Hi if a mic has a sensitivity of 10mV/Pa can I use this for SPL on the top of the calibration file. If not can I convert this for SPL? Thanks in advance

Hi folks. I want to measure the spectrum analysis of the computer fan. For this job, i buyed umk-1. And i use rew. I made this record the regular calibration file ( No sound in a room. Dead Silence) http://i.imgur.com/BMz3pyt.jpg http://i.imgur.com/JPsHRAS.jpg http://i.imgur.com/nnhEYir.jpg...

Hello friends I have a new Behringer ECM8000 microphone that I want to use for SPL measurements. I need to do that its sensitivity in mV/Pa. The attached technical specifications sheet says the sensitivity is 70 dB (positive and without any other unit). I thought it was an error given that...

I've ordered a Crown X-3000 (same specs as the Crown XLi 2500) to power a pair of SVS 16-46 passive subwoofers. I'm currently using a QSC RMX850, but I have to step up the voltage for it to work w/ my Yamaha AVR. I'm using a Behringer Xenyx to do the step up, but I'd like to eliminate it from...

I currently have a Rotel RB1070 powering my mains, I've just received a Rotel RB1080 to replace it. The 1070 has an input level of 1v, the 1080 has a sensitivity of 1.5v. Am I correct in assuming this will have an effect on the output level of the main channels? My SPL meter is out of action...

I am wondering about the two dips in the graph below at 110 Hz, 2x0 Hz rapid dip..... Can we hear if there is a dip that's steep and quick? I once read somewhere on the forum it mentioned about a 1/6 octave smoothing guideline. if we apply the 1/6 and see no dip, and the FR is relatively flat...

Hi, I just changed my Yamaha RX-473 for RX-673 and want to buy 5.0 speakers to listen to in a 13 square meters (11x11 feet) room, 50/50 musiv/movies (gonna buy a subwoofer too next month). I will not listen loud (live in an appartment) so please tell me, which characteristics listed in the...

Hi, I have little knowledge about home theater and I have this question in my mind about my avr. I bought my yamaha avr RX-V465 about a year ago and only now I learned that it's 1khz, What's the difference between the 1khz avr and 20-20khz avr? Do I really need to upgrade to the latter to hear...

Hello, I don't really understand what the sensitivity rating of speakers mean. I am currently using speakers that are rated at 89db on a budget receiver rated at 80w / channel. I am planning on getting a pair of new bookshelves that are rated at 92db. I googled some stuff online, but I'm not...

Hello, I have been looking into using a multimeter to measure the voltage coming off of my microphone, with knowledge of the sensitivity of the microphone, presumably, I can have a fairly good calibration of the SPL once the voltage is known and related to the sensitivity: my question: since it...

Hi Guys, Not sure if this is the correct forum to be posting this. So I was having this discussion concerning efficiency and sensitivity and some of the guys were lumping the terms together as if they were exchangeable. The one EE I discussed this with said both terms vary in the same way and...

I don't have Audyssey's dynamic equalization in my prepro and would like to set up a custom setting in my Velodyne SMS-1 to adjust subwoofer levels for lower SPLs. My problem thus far is that I can't find anything that says how much you adjust which frequencies as the SPL decreases. Does...

Hi, I'm new here and have looked around a bit, but could not find a thread that really addresses my topic in the way I was hoping. I built a sonosub for a 15" driver. Though it's large enough to qualify as an LLT (approx. 11.5 cubes, two 6" ports), I currently have it tuned to 20 Hz and am...

The other day I was thinking about my new onkyo 876. Now compare it to a onkyo 506. One has 140 watts of power, the other has 75. At Reference level what difference are we going to hear? Same goes for speakers, I looked at a high end polk, thats only rated 88db sensitivity, but with 300watts...

I'm about to start cutting a front "test baffle" for a 12inch woofer. Iwill post pics when it all starts. But before i do this i need to know roughly if my mids will match efficiency of woofer,(whithin 2-3dB) otherwise i may have to change woofers. Has anyone got real world sensitivity figures...

Though I've been an audioholic for years, there are many little things I've never really looked into very deep. Therefore I just want to make sure I am understanding this concept. My old pair of speakers was was rated at 93 db / 1w / 1m. My new pair of speakers are rated at at 84 db / 1w /...

So I been using an art cleanbox to boost the signal form my Onkyo receiver to +4dbu to feed my EP1500 pro amp. I also have a BFD DSP1124 in the chain. Receiver > clean box > BFD > Ep1500. Now what would you say the right sensitivity position for the switch be at -10 / +4? Rigth now Im not having...
