Thanks for the heads-up!

"Added support for Emotiva UMC-200 PEQ filters" What exactly does that mean? Will REW work with the UMC-200's calibration mic now? If so, I might actually be able to give it a try. From what I've read of REW's requirements, I can't run it otherwise, as my only Windows computer is my laptop with no HDMI. (I do have a SPL meter.)

I bought a UMIK-1 mic, downloaded REW, have the HDMI out on my MacBook Air and thought I was all set, but as I dig into all the comments it appears the REW software doesn't work at all with the current Mavericks OS. Grrrr. I have an old Windows laptop I could try, but it doesn't have HDMI and I think requires an outboard audio component. Grrrr +

No, it means that REW will create filters specifically designed to fit into the frequency, q, etc. specifications of the UMC - it won't try and optimise sound by telling you to create a filter at a frequency which the UMC doesn't support. It certainly won't use the UMC's mic - as there's no calibration file available. I have a UMIK-1. You don't have to have HDMI - you can run REW with a laptop with a decent sound card, but a laptop with multichannel HDMI support does make life much easier. Without HDMI, REW only supports one channel, so you have to do lots of unplugging/plugging in of cables to do all 5 or 7 channels - which is a royal pain the behind if your UMC is in a rack or cupboard etc.. With HDMI, if your HDMI support multi channel (which not all of them do), you can select in software which output you want to use.

Sorry if this is off topic, but does any version of REW support the PT-7030 PEQ filters?
Thanks,
Chuck

Not directly, but i suspect that the PEQ in the 7030 is similar to the one on the UMC200 (regarding filters frequency, maximum gain/cut and Q values), as they use the same Cirrus DSP.

No the PEQs of the UMC-200 and PT-7030 are NOT similar! I am wondering a little bit why you are thinking this, because this was discussed and a comparison shown (also by me) in several threads you participated in...
The PEQ of the PT-7030 equals the one of the Rotel RSP-1572 and is inferior to the one of the UMC-200.

Thanks for your responses. I just checked on Home Theater Shack and found that REW does not support the filters required for the Rotel RSp-1572. I'll be working it manually, by ear!
Cheers!

No problem. Imho it is better in almost every case to do it manually. There is also a great article in the REW forums about using some brainpower and achieve the same results with less filters as with the filters recommended by REW.

You have to go to System Preferences > Security & Privacy > General > and Allow Apps Downloaded from ANYWHERE. Run REW the first time, then you can change the setting back to your previous setting.

Is the averaged response with or without any crossover? Looks like you don't get the desired target curve. You would need to set it lower. Before doing that check the excess group delay of the single measurements if there are any non minimum phase regions. Don't apply any boost in those regions. urwi, the measure is the average of the 3 locations on the listening position (LCR), and is without any crossover, delays, etc. Do you mind to translate this in English : "check the excess group delay of the single measurements if there are any non minimum phase regions" :-D Regarding boosting, i only use the PEQ to cut peaks.

I,m new to the rew thing never used it yet, I was wondering if I could use the u-control UCA222 that Andrew used in his sub/rew demo, could I hook it up directly to each input of the xpa-5 get the measurements and then apply them to the UMC.
How would I add a USP-1 in the mix?

So far i've been using REW generic filters, but with B18 version, i've updated the filters to the exact umc200 frequencies. I've tried a new approach, reducing the number of filters, using lower Q values (to wider the filter scope): I've taken new full measures, one with the FLAT setting, and another with EQ Manual 2, with REW filters applied to all channels, but the results aren't still what i'm trying to achieve: As you can see, there is still a large null in the 70Hz-140Hz, and a huge "dip" in the 400Hz-2kHz. The first dip could be due to the crossover at 120Hz, so i will try lowering the crossover to 80-100H<, to try to achieve a better output on the 70-100Hz region. I will also try to lower the 400Hz-2KHz region, by at leat -5db. Addressing this two point, i think i will be able to achieve a nice house curve. Finally, i have a specific question regarding REW: - as REW is only capable to generate a stereo signal, the center and surround channels are not used. This complicates the analisys of the full frequency measures, because i cant see the effect this channels add to the final sound. As the UMC200 has a All Stereo Mode, it would enable to generate a signal with all the speakers playing. Would it be possible to use this mode to produce a full frequency measure, with all the 5.1 speakers?

No, it doesn't work with Mavericks. I'm a Mac tech, and of course all those protections are turned off. It just doesn't work, and the REW forums say the same thing. It appears to be an audio bug in Mavericks that may get fixed, soon I hope. Mel
