Eurorack UB802 v XENYX 502/802

Hi,

First post. Just got REW and trying to get prepared to take some measurements of my audio room to figure out room treatments needed.

I've been reaading a lot of the threads but I'm confused at this point.

The REW Cabling and Connection Basics Guide says Xenyx 802 then 502 but shows a picture of Eurorack UB802.

Which one is the recommended on for use with the ECM8000? Price is not much of an issue. just looking for accurate and simply to use/setup.

Re: Eurorack UB802 v XENYX 502/802

Hi, it's simpler to use a combined preamp/USB interface. I've recently used/reviewed the Focusrite Scarlett 2i2 and MOTU Microbook II (more powerful but definitely a "learning curve" unit). Either of those, with a calibrated EMM-6 (or ECM) from Cross-spectrum Labs, will give you something that will work reliably and be fairly "future proof".

Thanks but it sure doesn't sound simpler.

Simpler to me would be the Dayton UMM-6 USB microphone. It can plug right into the computer. No?

Am I missing something?

Uhm... well, a lot of things plug into computers. Sorry for responding, my bad.

I apologize if my response came off unappreciative (was typing from phone)

I'm really new to all of this so when I looked at what you suggested there were a lot of buttons!!

I'm sure I could figure it out somehow but the fact that there is step by step guides on the other mentioned made me a little comfortable.

Hi, the setup with a USB interface is shown in the last diagram of the setup guide:

Re: Eurorack UB802 v XENYX 502/802

Hello,
I just bought a XENYX Q502USB mixer/soundcard.
Having read the REW guides, I tried to set up a test measurement with my mic (Behringer ECM8000) inserted in Line 1 mic input, and test signal outputted to one channel of the 2-track pin-jack output (tried the jack main out, too).
But when I start to measure, seems that the REW input channel wasn't the microphone, because I obtain a perfectly flat response from 20 Hz to 20 kHz...
Anyone can help me to have a correct setup of this controller? I bought the Q502USB especially for the full-duplex feature, but seems difficult to me how to use it...
Thanks a lot,
Leo.
EDIT: SOLVED!
Seems that if in REW I use the WDM drivers I cannot choose the correct mic input channel (in my case, the right channel).
For test signals output I choosed the left channel, so all is finally working, now.

Re: Eurorack UB802 v XENYX 502/802

I have XENYX Q502USB (recognized as "USB audio codec") on hand with ECM8000 mic.
Using Java / 48KHz/ output and input are "speakers USB audio codec" and "microphone USB audio codec", level set to -12dB.
Input mic "Z".
The problem is that REW shows too high input level (o dB headroom), also when testing levels even small level PN is shown as "OVER" on the SPL meter.
Obviously there is too high digital level somewhere.

Can anybody please help solve/explain this behavious with Q502USB/ECM8000?

There are no problems with UMIK-1. But a friend is setting up with the a/m Behringer so trying to help.

Thanks in advance,
Draki

Check that the gain setting for the mic input isn't too high and that there isn't some monitoring active.

Re: Eurorack UB802 v XENYX 502/802

Thanks for responding, John.

The gain is very low (actually this is happening with gain set to min).

As far as I can see (or can't see) there is nothing on the device about monitoring.
The mic is in the mic input, USB to the laptop/REW, main out from the Q502 to the amp (tried both L and R).

Can't figure it out...? It's supposed to be simple.

Is Focusrite Scarlet 2i2 "REW-approved" in practice? There is a chance for exchanging the Q502 for the 2i2, but only if the outcome is proved to work...
