I am trying to calibrate 2 UXL18 18" subwoofers in my HT using REW Wizard. I have the Checkmate CM-140 and I am trying to individually test each subwoofer to match 75db then adjust their gain until they are both level matched. My problem is this: 1. What should I set the SPL meter to? 2. I got...

Hello! I have Galaxy CM-140. In my room in A-w. mode it shows around 30db, but in C-w. mode it shows about 10db higher. (~40-42db) - is that normal? :huh:

When I'm measuring SPL using speaker pink noise with my Galaxy CM-140 (on dBC, slow) I'm getting approx 5dB higher readings than REW does when using UMIK-1 with calibration data. Could the calibration on my CM-140 be that much off? Can I be certain that the input levels from the UMIK-1 is...

Hi, I calibrated both sound card UCA202 and SPLmeter/mic (Galaxy CM140), set the levels and then run my first room measurement. The result is a disaster: a terrible "yoyo" in the freq. response, and similar shape for the waterfall. Here is the graph: LINK Any suggestion, comment, support is...

Hi Guys, I guess this question should be placed here: I recently got a Behringer UCA 202 USB soundcard and a Galaxy CM-140. Since I don't own a stereo jack to RCA just yet, I tried a mono jack to RCA as well as a composite jack to RCA, which immediately both showed me much higher dB levels on...

Hi Im new to REW and i have just bought a Galaxy CM-140 spl meter and a Beringer UCA202. I think i have everything hooked up ok but when i run a test tone i get a weird curve on the low end. Am i doing something stupid? Thanks Ken

Just wanted to know, my Radioshack SPL meter was stolen last week so I'm looking at the Galaxy CM-140. It's a lot more expensive, but the Radioshack analog model I had isn't available anymore. My question is, how much more accurate is the CM-140 when calibrating speaker and subwoofer levels...

For some reason I am having a of a time with feedback as soon as I connect the Galaxy CM-140 using Turtle Beach Amigo II USB sound card. I have tried 2 different computers with same results. I have Calibrated the Soundcard and the graph look good. I go to Check levels and I can not even get...

Hi! I was going to but it but is listed down to 31.5hz only so is it not good for subs then? Thanks

Hi There. can someone tell me If you can either get the Galaxy cm140 in Australia or a company that will ship there? OR better yet if someone has a spare they want to sell!!! thanks dave

I am in the process of upgrading my spl meter. I want to measure full range in my HT and I have read that I cannot do that with my RS meter. I have read alot about the benefits of the Galaxy cm-140 but not so much about the cm-150. I understand there is a big price difference but is there any...

I'm looking at the Cal file for the Galaxy 140 and they go like this: 5.0 -21.89 5.6 -19.60 6.3 -18.48 7.1 -17.22 8.0 -15.87 9.0 -14.59 ... 80.0 -0.75 90.0 -0.53 100.0 -0.35 Does that mean the meter reads low and I need to *ADD* 21.89db at 5hz? Just want to clarify.

Here is a graph I made with my new cm-140. I used a test tone CD going from 15 to 120 Hz. Just curious how this looks and if you think I will need to get a BFD or not? Are the bumps in the 30-40 Hz range and around 80-85 Hz going to make it boomy? I will try REW once I get my...

I just purchased the Galaxy CM-140 up here in Calgary, Alberta, Canada. No stores here actually carry it in stock so it must be ordered. It cost $145 Canadian plus tax. When I placed the order (and had to pay ahead of time) it was the beginning of April 2008. I finally received it now at the...

I already have a Radio Shack Sound Level Meter- Model Number 33-2050. I've ordered a Behringer ECM8000 Microphone and some Dayton CMX-15K XLR Microphone Cable to go with it. And "soon" I expect to order an external USB soundcard with suitable microphone/input/output connections so my laptop...

I see that the calibration file for the Galaxy SPL meter covers the range from 5 Hz up to 200 Hz. Now why has it been recommended to uncheck C-Weighting in REW? If doing our usual subwoofer response testing with REW (i.e. sweep from 0 Hz to 200 Hz), wouldn't we get the same result whether the...

I have the Galaxy CM-140 on order. Can't wait to try it out with the new improved REW. Just wanted to verify ahead of time whether this SPL meter should be set to fast or slow with REW. I've seen posts say to set it to Fast where as if one is using the Radio Shack SPL meters, it is...

Hi all, I'm relatively new to the forum but have done extensive reading here. My recently aquired PB12 Plus/2 is in need of calibrating. So my question is which route to go ifor EQing; the Galaxy SPL meter/mic or the ECM8000. I currently have a RS SPL (analog) meter but still need a good mic...

Hello Everyone, This is my first post and I apologize beforehand if this topic has been dealt with already but what I have read regarding SPL meters thus far has left me confused :mooooh:. I already own a Behringer ECM8000 mic, a Behringer Eurorack UB1202 preamp and a Behringer FBQ2496...
