Well, I’m deep in the process of trying to integrate 2 different subwoofers with an existing 7.2 home theater system using a miniDSP 2x4 DSP for the subs. However, that’s not what this post is about. During this process I decided to do baseline measurements of the existing speaker settings...

Hi Guys Great forum. I have been lurking for some time, but not really posted/replied as I really do not have the knowledge to make any meaningful contributions. But I am stuck…. I bought the minidsp UMIK-1 I followed the UMIK-1 setup with REW - below...

As some of you may know I prefer large floorstanders and a sub to bookshelf speakers and a sub. Many people are in the opposite camp so I'm trying to understand why. With some time to play around and experiment I've moved my bedroom system into my main listening/HT room and have several...

I dont know why, but usually my master bus peak is something like -20db cause i can push volume from the soundcard to speakers. If i put some limiter to master bus and try to push levels something like -5db i heard lots of clashing and it does not sound as good as lower volumes. And all my...

[/B][/B]Finally, I successfully get the signal in all channels with NanoAVR-DL by changing the system setting in NanoAVR programmer from auto to 7.1 channel. Now, after many attemps or trials, I never get enough input level to get the first mic. Position measured. I followed the manual...

I have REW running on my Mac (OSX Yosemite). I have a umik1. For whatever reason LZpeak never goes above 100.6db. I'll hit it at -25db or 0db (with my ears plugged). Should I be using LAFmax? Even if I crank up the volume to 0db I still don't hit > 100.6db for LAFmax which I would expect...

Anyone try a Neutral Density filter on their projector to improve black levels?

I took 3 sweeps at different volume levels (I calibrated each using SPL meter), no other changes. purple = 85dB green = 75dB red = 65dB The 200hz and up region is what I was expecting to see across the entire frequency spectrum. Look at how bloated the bass gets on the quieter sweeps. The 65dB...

Hi - I have the UMIK-1. I have set everything up correctly as far as I know - set output device and input device. Used unique calibration file for UMIK. I adjust the volume to get the levels the same and when I hit next the meters go grey and don't do anything - see attached screen shot - no...

Hello All: My goal is to understand how to use check levels correctly. I have already a) calibrated my Scarlett 2i2 soundcard; b) loaded the calibration file for my Dayton EMM-6; and c) set my SPL output and input levels on my Scarlett 2i2 according to this article [1]. I can report the...

Hi guys, I am brand new to REW (and home audio for that matter), and I'm hoping for some clarification with the "check levels" test. When I try to adjust the DB FS reading to -18, I find that I have to turn the gain on my mic all the way up on the m-audio mobile pre, and even then the volume...

Hi! Noob asking for a sanity-check :coocoo: I was running through the REW "CHECK LEVELS procedure, and noticed something peculiar with the calibration test signal. The REW manual describes it as pink noise, but it must be hi-pass filtered. Compared to other pink noise signals I'm familiar...

Ok, forgive me if avr's compensate for this already somehow, but l'm getting ready to bi-amp my mains for the 1st time with a denon avr-x2000 OR nad T 748v2. 7 year old midlevel Polks that I still really like. When bi-amping the mains, do all of the other speakers have to have their levels...

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 everybody! I initially heard of this site because of REW a few years ago. I'm going to make an effort this year to hang around here, probably in the Movies and Pro Audio subforums. I'm into making music, so I invest in my project studio more than on my home theater. I do love movies though!!

I just received my UMIK-1 from Cross Spectrum. I added the sensitivity measurement to the top line of the *.cal file that I downloaed from MiniDSP. My mic is seen by REW and loaded along with the narrow_band_response_0_degree.cal file. The question that I have is what whenever I "Check Levels"...

I got some grey material, A4 size sample, about N7.5, pinned it up against my N6.4 painted screen. Problem I seem to be getting is when I stand up, the black levels significantly drop poorly. It seems there is a lot of gain off axis? I like everything about this material over my painted...

For some reason, I am having difficulty understanding the relationship between the Control Input Volume and the dB FS Output level shown on the REW SPL Meter. This misunderstanding arose after I entered the Sensitivity parameter for my UMM-6 USB mic into the calibration file, and then tried to...

Hello everyone, I'm new to REW and these forums. I have read a few guides on this forum on the topics of for instance what hardware to use for REW and about the hard knee house curve. There is one issue that I'm having that I have not seen mentioned in other threads so that's why I'm making...
