    Hi there, My first real post. For my first attempts at using REW, I borrowed a friend's RadioShack SPL meter, and everything seemed to work fine. I've now started to use my newly purchased Galaxy meter. The meter itself appears to be working fine. However, when I connect it to my UCA-202...

    Hello, I am considering upgrading to a new mic for REW measurements. I may also get a DSP1124P... My current setup is with a Macbook Pro with internal sound card which has line in capability and a Digital RS SPL meter. I want to know the pros/cons of going with a Mic/pre-amp setup vs a CM-140...

    I have an opportunity to get Galaxy CM-140 sound level meters at wholesale prices, and I'd like to see if there is enough interest out there for me to start selling them along with my "value added" services. The nice thing is that I don't have to order them in large volumes which means I can...

    Hello everyone. Please forgive me if this question has been answered before; I couldn't find it. I'm trying to use the CM-140 manually, without Room EQ Wizard, by adding the correction values in the REW cal file and the standard C-weighting curve to my measurements. According to this post by...

    SOLD!!! This unit is in excellent condition and operates perfectly. I do not have the manual, I don't think (haven't looked yet.), but really these are so simple to operate that there is no need for it. It will come with the 9 volt battery in it and the windscreen. These are usually around...

    I have an Integra DHC 40.1 with MultEQ. After Audyssey calibration, the pre-amp test internal test tones are supposed to read 75dBC at listening position, but mine reads 70dB. With REW measurements, things look consistent. Is my CM-140 off by 5dBC? I am in Portland, OR. If it is off, is there a...

    I've read a lot of the back and forth on the matter but I wanted to make a post to help solidify my decision. I plan to use the setup to calibrate the BFD, full range room calibration, and testing DIY speaker designs. Any input on the matter would be welcomed. I'm deciding between a...

    I have been using a CM-140 in my home theater for the past 6 months to set speaker levels. I have probably used it in 4 sessions - 30 minutes each. The problem is that the meter previously measured ambient noise at around 49dB (i.e. all sources off, AC off, etc -- basically as quiet as the room...

    I'm considering the Galaxy mic as an upgrade from using an ECM8000 and mixer. From what I've read, it sounds like I can connect the CM-140 directly into my sound card using a 3.5 mono plug. I will not need a mixer/phantom power supply/preamp with the CM-140....is that correct? Since it...

    I see this only goes down to 31.5 Hz? Am I correct? I would need to use the Radio Shack meter for Bass and this up to 8Khz?

    I'm planning on buying the Galaxy CM-140 soon and I was wondering what kind of output does it have? I read through the REW Cabling and Connection Basics sticky and it seems to mention that the Galaxy CM-140 uses rca outputs. But I read a post on another thread where someone mentioned that it had...

    I am getting ready to buy all the "equipment" needed to check out my speakers and integrate an IB subwoofer. I plan to get a Sound Blaster live external USB card for my laptop and a BFD. My question is about mics and SPL meters. I am new to this and it is a bit confusing. Could someone explain...

    Hi all, I have just ordered a PB13 Ultra. I expect I will have some REW and Behringer related questions for you later. For now my query is related to the Galaxy. There probably is an easy answer but it doesn't make sense to me as I have no idea how this all works apart from trying to follow...
