It looks like the XLR outputs can be switched from mic to line level, so all you need is a cable with a female XLR to a 1/4" TS, or XLR to RCA, and connect between the line out and either line or AUX in.I can't even get a loop back?
Quickest is to make some measurements and post them here for us to take a look at.OK, sounds good. Is there a way to make sure I am getting correct measurments, eg all the HDMI settings are set correctly and the USBPre2 settings in the PC are set correctly?
There are probably a few (or more than a few) things I should be doing for better internationalisation support, but the nights are short and my todo list is long...BTW John, REW in Japanese windows OS does not display characters correctly, but on some pull down menus it does??? Upon closing it shows Japanese characters fine.
I have setup this way: mic in XLR input 2 > USB > PC > HDMI > RecieverI also have a USBPre2 which I'm using to successfully make measurements with REW. I'm not experiencing the problems you're describing with my setup, but I'm using the USBPre2 for both input and output sources, whereas if I understand you right, you're using HDMI for the output and only using the USBPre2 as the mic input?
How exactly do you have everything connected and configured?
Are you talking about the knob circled in red or yellow in the below pic? I can only get the gain to go up and down by adjusting the knob in yellow.Adjusting the output gain on the tiny little knob is annoying, so I've set dipswitch B5 to make the large headphone knob control the output gain, which is much less annoying.
I finally made a calibration of the sound card via the cabled option. I can't seem to make one with the loop feature.The knob circled in red on your image controls *output* gain (volume), if you're using the USBPre2 as the source of your audio. Dipswitch B5 swaps that knob with the larger one just to the right of it labelled 'Phones', giving you a more convenient knob to control output volume with.
I believe you've said that you're using HDMI out for your actual testing so it won't make any difference for that since output volume will be controlled by your HDMI output volume settings and whatever your receiver/amp is set to.
For taking actual in room measurements, I have the input selector for the channel I'm using (1 in my case) set to 'Mic' because the input is a microphone, is plugged into the mic input, and needs the extra signal amplifications that microphones do.
I only use the 'Line' input when doing a loopback test.
Can you get the loopback test working as described in my previous message?
Reading back over the problems you're discussing, I'm wondering if you're getting the level setting process right. When you do 'Check Levels' you should be adjusting your output volume on the HDMI output and the receiver to produce a reasonable volume from the speakers (if you're checking that with a sound level meter, it should be 75dB or whatever you're aiming for). The input level should be around -18dB as per the instructions - you shouldn't be trying to set it for -12dB or higher as you then have a tendency to get clipping when there are peaks in the room response at particular frequencies, which may be what you're experiencing?
Well it's good that you have a calibration via the loop, that suggests everything is working properly. How did it look, it should be very flat indeed?I finally made a calibration of the sound card via the cabled option. I can't seem to make one with the loop feature.
Also with my setup, both the knob circled in yellow and the volume on the receiver can change the levels. Is this normal?
