calibrating

Hello, I just finished building a pair of speakers and I wanted to take a look at the spl spectrum. I installed REW, got a USB-mic with calibration file and started measuring. When measuring the speakers, I noticed a dip at 500Hz, 4000Hz and around 13-14 kHz. I measured different other speakers...

Hello, all. I haven't messed around with REW in about a year, but I was trying to set it up yesterday again to take some measurements and dial in my 2 new subs. Each time I try to calibrate it, it keeps giving me an error that the audio level is too low, (-129dB). When I tap on the mic on...

Hello, denizens of Home Theater Shack. I am totally confounded as I try to make Saffire MixControl work with REW. I'm aware that calibrating the sound card isn't too important. Still, I'd like to learn how to do it, so that I know more about the MixControl software. I need to create a loopback...

Hello, I am in need of help! I am currently in the process of treating my room to utilize my new Focal Alphas, and I am new to REW. First, I am having some difficulty calibrating my REW. For some reason, when I try to calibrate REW's SPL meter, using a behringer ecm8000, the spl rating is...

Hey first time poster. I have owned this projector for a bit over a year, and for the most part have been impressed by the quality of such a cheap unit. We clearly live in privileged times. But.. I have noticed that sometimes it's production of very bright colors can look pretty strange. A...

I am trying to calibrate my four way miniDSP OpenDRC-DA8 based speakers. My first step is to balance the four drivers in the miniDSP panel. What speaker response should I be aiming for? Flat response sounds horrible; I balanced the drivers using a 3db roll off per octave using the EQ panel of...

So today I calibrated my TV Sharp 40LE820 (at least tried) , but still new to using a i1display pro and HCFR (+i1profiler which I didn't use this time). Gamma I know is not perfect, but it is as close as I could get it, well everything is as close as i could get it. But, the RGB levels are...

Hi, I'm new to the world of REW so be gentle. I started yesterday and tried to calibrate my soundcard (Creative Soundblaster MP3+). The graph I got looks OK at the begining got then goes crazy at the end, what am I doing wrong?

When calibrating the audio interface, instructions say to connect the line-in to the line-out jack. Why not connect the line-out jack to the XLR mic-in? Aren't those the ports that are generally used when performing measurements? I have a Tascam US 322 with Dayton EMM-6 microphone. Thanks, Six.

Well, calibrating in terms of trying to get them to contribute and not cancel. I have two subs in the living room currently, and they are not quite the same. Both 10", one down-firing, one front-firing, both ported, one from 2013 and the other from 1998, both have 150W continuous, same...

Just hooked up my USB interface Behringer UMC22 for calibration, drivers used: 64-Bit USB Audio Driver 2.8.40. Set up a loopback between OUT2 and IN2 and configuration the preferences in REW according to the enclosed screenshots. But when running the calibration it's like REW don't get the...

I'm new to REW and still trying to figure things out. I am running REW V5.01 BETA 22 build 3423 on my laptop, 32bit Windows 7 and don't believe the SPL values I am getting with my new UMIK-1 with calibration file when using ASIO4ALL v. 2. Not sure if I'm doing something wrong or ? I...

Dear hometheatershack community, I'm a home recording musician from Germany and got the following equipment for mixing: Notebook: Asus X52DE Power Amplifier: Sony TA-F470 Speakers: JBL Control 5 I usually use the un-eq-ed output from my notebook, plug it into the AUX IN from the power amp and...

im trying to calibrate my UCA222 using REW. Here is my graph

I'm in need of someone's guidance. I'm trying to calibrate my sub using REW 5.0, my SPL as a mic with calibration file (I understand this isn't ideal) connected to Behringer U-control UCA222 USB audio interface, and Uno - 1-In/1-Out USB Bus-Powered MIDI Interface, to go with the Feedback...

I currently have 2 PB12-NSD installed in the front of the room just inside the front L & R Mains and 2 PC12-NSD that should arrive in a few days which i will be installing in the rear L & R corners below my L& R Rear surrounds. I figure I will keep them in like pairs on each output. 2 PB12-NSD...

Was going thru the video processing menu of my Oppo BDP-103 and started to think if I should really use this? Would calibrating the Oppo conflict or add to the calibration that was done on the TV? How does one calibrate different inputs? Right now I have everything going to my Denon 4311, via...

Hello, I am new to REW. I just bought a new audio interface, a Focusrite Saffire Pro 40, which I have not yet used for any recording or playback. I connected a loop from output 1 into input1 and set the levels. Using the latest beta REW, the calibration graph shows a rapid drop off in...

Having an issue calibrating this sound card and SPL meter. I can get sound to play but when I try to get REW to generate a signal I get this. Appreciate the help thanks.

Hello, To make some measurements, my mic will be connected to a mixer (to use the phantom power). When calibrating the soundcard, should I follow the instructions in the manual (ie : connecting the soundcard line input to the line output) or should I include the mixer in the path (soundcard to...
