Audio Advantage SRM & Vista -- Calibration

[allredp]

I have the Audio Advantage SRM soundcard that Brucek reviewed a few weeks ago, running on an i-Mac with Vista in Boot Camp. I also have the Galaxy CM-140 spl/mic.

So, after installing the soundcard driver from the webpage, and insuring the control panel looks just like the screen shots Brucek posted in his review, I can't seem to get it calibrated!

My levels aren't high enough--only rising to a pegged-out -37db!

So, here's Brucek's response to my initial questions about this from a PM:

Phil,

I'm a bit confused by this statement:
When I go to "measure" and try to get the levels to match up, my Output is very high, while my L and R channels remain very low (in fact, I can only see my L increase when I peg my AA SRM levels as high as possible and it only goes into the 30's dbs). .

You have the Right channel looped back and the Left unhooked, how could you see the Left line-in move at all ? - it should not.
You're attempting to calibrate the Right Channel and so it should be the only channel to show any level.
Hopefully you don't have the "Use Left Channel as Calibrate" checkbox in REW checked. It is left unchecked and unused.

The monitor is shut off by disabling line-in in the playback devices level control tab. Be sure the volume is at zero and the speaker icon is red by clicking it off. The same goes for the microphone-in.
_____

So, I've made sure that I have the soundcard's R of the output connected to the R of the input (via the 3.5mm stereo jacks split into dual RCA adapter). Other than the USB powercord, that's all the cabling, right?

When I run REW and go to the Settings for the Soundard to calibrate it, I can't get the levels to move when I "measure."

I'm manipulating the volume via the Audio Advantage soundcard's control panel (as I've selected the soundcard's "speakers" for the output and the "soundcards "line in" for the input.

I don't have the "left channel as calibration reference" selected either.

When I go to measure, in the page before I actually "measure" I can see the "left" channel dancing slightly around the -41.7 db level (in blue) and nothing in the "right" side, and the "output" is greyed-out.

When I hit "next" the output is up at -12 db and the LEFT is still in the -40's, but only increased into the -30's when I use the mixer "recording level" slider in the AA control panel (if I slide the "master" in the mixer control panel it doesn't do anything). Only when I drop the "recording level" down to almost 0 does the "RIGHT" channel begin the rise--but only to 42.7 db. When I go ahead and try to get a measurement, it runs the test and says that my levels only reached -41.6 db...

I'm stuck!

Thanks for the help,
Phil

BTW, I'd love to post the pics of these windows, but don't know how to grab a screen shot--any help there?

I'd love to post the pics of these windows, but don't know how to grab a screen shot

Click the mouse cursor in the screen you want to capture and press Alt and PrtScr keys. This captures that active screen to the clipboard. Then use any graphics program to Paste the clipboard data and then manipulate the size to 800 wide (or less) and save as jpg. Paint or Photoshop etc.... Tell me if you have any trouble with that and I can explain further.

I'd like to see your REW Settings page if possible.

This is beginning to sound like another of our many Mac problems (that really only John can solve - if at all).

Forgetting about REW for a minute, are you able to simply hook the analog line-out to your receiver and play sound?

brucek

[allredp]

Yes, I can hear music and sounds through the card--so that's good, right?!

I'll work on capturing the screen-shots when I get home tonight to show you each menu and my settings, etc.

Thanks much,
Phil

[allredp]

OK, I've switched to a PC (Dell Latitude D620) to see if we're having a Mac problem, but I have the same calibration/loop-back issue as before!

So, that's good news on one hand (the iMac may still be usable).

Here's the screenshots of the measurement page and the soundcard's speakers settings and mixer settings.







BTW, I do have the card hooked up via the USB, and I have the stereo 3.5mm input and output jacks with RCA R/L adapters hooked up via the R channels only. There's nothing hooking up the L channel.

I'm sure it is something stupid on my end and hope you'll be able to put me out of my self-created REW misery!

Thanks,
Phil

[allredp]

BTW, I did this as "default" and as "speakers" and "line in" settings in the REW settings for input/output. Either way, I have this problem...

[brucek]

A couple of things....

Your Speakers Tab of the mixer shows a green light on Speaker Equalization, which means on the Equalizer tab you have it enabled. You want to go to that tab and press the enable button again to disable the equalizer (be sure the light goes out).

Also be sure no features are enabled on the Effects tab screen. Shut them all off.

Also on the Mixer tab, be sure to pull the volume sliders to zero for microphone and line-in for playback.

I see you have the Default selected on the REW tab for Output and Input device. Are you indeed able to pull that down and select the card itself? You should be able to (see my Vista soundcard thread on that for a picture). I'm concerned that Default setting may be selecting the on-board card instead of the SRM input.

Other than that it makes no sense at all. In fact I have to say my Input is a bit too sensitive for my liking. I can hardly get the volume slider off zero and its half way up full.....

Do you indeed see the driver in the Device Manager? Here's a Vista picture of it, but XP would be close to this... I show the properties tab too..



Also note that the Universal Serial Bus Controllers listing in the Device manager will show a Composite device in the USB port it's connected to..

brucek

[allredp]

So, I've fixed the EQ and the line levels are zero'ed out. And I've made sure I can (and have) selected the AA card for input and output as you can see here:

I think I've found a problem! I discovered something when I toggled between the 44.1 and 48kHz sample rates (just trying anything) and up came this message:

So, does that help?

BTW, I did go to the device manager and can see and select the AA card, I also checked the USB port and it does say composite device...

I really appreciate the help,
Phil

[allredp]

Clearly have a problem as I decided to just try the measuring for calibration again for the of it.

This message popped up:

[allredp]

More screenshots to help you help me!

I'm just cursed with REW, I tell you...



BTW, I restarted my computer (the Dell laptop) and I can now switch between the sampling rates without the device error problem... Must have lost the card's connections when the laptop went into power-save yesterday.

I don't understand how this isn't working! Something is wrong, clearly, between two different laptops (iMac and Dell), I get the same thing--levels too low and nothing from the R channel which is the only one hooked up!

Volumes are pegged...

HELP!

[brucek]

I don't understand how this isn't working!

Yeah, this is a tough one. I know with my system, there was no messing around at all with this card. Click, and it was working. So, something is quite wacky here. I hesitate to ask if you feel that your cables are fine that you're using (easy enough to check by testing them. You said the output was working, so maybe swap the input set with the output to be sure that the splitter is good.... and also check the loopback cable).

Can you generate a Debug file for the card and post it here? Maybe we can get an idea about what's happening with the outputs and inputs.
Start REW and go to the Settings page and Soundcard tab. Press the Generate Debug File and save it to the desktop. Then attach the file or the text to your post.

[JohnM]

Do you see any input level showing on the meters in the record settings section of the SRM's own mixer panel? Which input connector are you using on the SRM?

[allredp]

Hey John and Brucek,

Here's a pic of my SRM's meters for the line in: (I have wondered why they aren't lit, when Brucek's are in his review pics)



As per my connections:

I'm using the 3.5mm "Out (7/8)" with a headphone symbol and the 3.5mm "Stereo Mic In" (both of which are on the same end of the SRM card--it is also the one with the "out 5.1" (looks like an S-video port).

I am using the Radio Shack 3.5mm stereo to R/L RCA adapters suggested in the REW help files, and I'm using a gold-ended 3' standard RCA cable.

The SRM is connected to the Dell pc laptop via the USB and I can manipulate the volume with the rocker dial on the SRM which shows a volume screen on the laptop.

I really appreciate the help--I'm really excited and anxious to get measuring with this amazing tool!

Thanks,
Phil

OK, here's the Debug file--I apologize for its length!

Phil, use the connectors on the other end (where the USB connector plugs in).

"My don't I feel silly..."

Words cannot describe how stupid I feel!!! I switched the cables to the other side as you said, and it works!

Here's the graph:



BTW, what do I need to do for this to clean up on the high frequency end?

What I don't understand is that the "other" input/outputs are labeled "SPDIF" and I thought they were just the digital ones.

Any help with that so I don't make similar mistakes in the future?!

BTW, I will happily begin a new file (or keep this one) for future Vista/SRM REW travelers...

When I get home I'm going to go measuring bonkers! I've been sitting on my new equipment for several weeks (see my signature) and I'm ready with my carpenter buddy to build a proscenium and get my acoustic treatments in. I have a roll of JM Linacoustic and about 30 panels of spinglass (3" rigid) and mineral wool (3" rigid) in the garage ready to be used!

Can't thank you guys enough, John and Brucek!

[brucek]

I'm using the 3.5mm "Out (7/8)" with a headphone symbol and the 3.5mm "Stereo Mic In"

Oh my, oh my, I wish you had said this before.... I just came back in the house and saw this..... I see John caught it before I returned. That's good............ I just assumed you were using the line-in and out.... oh well...... (look at the picture of my line cables in my review).

what do I need to do for this to clean up on the high frequency end?

yeah, play with the output level a bit when you take the soundcard cal measurement. Usually about -6dB to -9dB works best, but adjust until you get a good chart and file....

What I don't understand is that the "other" input/outputs are labeled "SPDIF" and I thought they were just the digital ones

I think if you look close you'll see it says Line/SPDIF, which is a dual purpose jack. That's what the two adapters are for that you have in the box. Plug them in and it changes to accept an optical cable for digital. If you set the port to digital, you plug in the adapter and an optical cable. Set it to analog and it's a line jack when you remove the adapter that accepts 3.5mm stereo plugs.

[allredp]

OK, that makes better sense to me now--I'm sorry I missed that in your pics! I just went back to see where your cables were and sure enough--they are coming out of the USB side! I think I saw that before, but assumed that it was just your SPDIF/optical--since there isn't the RCA splitter on it--though I can see that you labeled it main speakers. I can now understand what the 7/8 is for on the other side. Shoot, I hate making such a dumb mistake, but I never work with outboard soundcards, etc. and so I guess I've got a steep learning curve ahead!

So, as per the calibration graph I don't seem to get much of a difference between using -12, -10, -8, or -6?

How do I get mine to look like yours & what's that other line the jags down in the middle of the FR graph?

Here's -12:



Here's -10:



Here's -8:



and here's -6:



This is getting close!

[allredp]

In the meantime, here's my graph from the "check calibration" step:



How's that look?

[brucek]

How do I get mine to look like yours & what's that other line the jags down in the middle of the FR graph?

That jaggy line is the meter calibration file (which we don't usually load until the soundcard calibration is all finished). It looks funny because of the very exaggerated vertical scale axis that the graph uses. Note that it is minus three to plus three (only 6dB full scale). When we are doing measurements the vertical scale should be set to 45dB-105dB. That's a 60dB swing.

So, you can see the soundcard response is fairly good, only down less than a dB by 10Hz.

You're getting a small amount of oscillation at the higher frequencies that can be caused during the soundcard cal test from the input or output level not being correct or perhaps some fairly capacitive cables etc. Play with it a bit, or if your doing sub only measures, use it the way it is... In fact, it looks so close to my file, I could just give you mine and it would be fine. You can see that mine wants to oscillate at the higher frequencies also... not uncommon when this test is done on any card.

Anyway, remember when you post any graph other than the soundcard cal, the vertical scale is set to 45dB-105dB and horizontal scale is 15Hz-200Hz for subs and whatever top range for full range.

here's my graph from the "check calibration" step

I don't understand what you mean by this.. what is the graph of?

brucek

[allredp]

Here's the same using -6 input setting:



Is this right? I'm trying to follow all the instructions--I hate being high-maintenance...

Thanks again,

Phil

[brucek]

Oh, I see what it is...................

This is the measure of a loopback cable to check the soundcard cal file?

You must clear the meter cal file, and set the target level etc to 75dB

brucek

[allredp]

Very cool then!

If you don't mind, just send me your file if you think that will work well.

Much thanks man!

[allredp]

Yes, that's the check of the loopback.

I did clear the calibration file and I think the level is at 75db (how do I check?).

The -6 one looked pretty good, didn't it?

So, how can I get your file--I'm assuming that it will be easy to load by browsing my saved location...

BTW, I do plan on using this mainly for sub calibration, but do want to use the full spectrum as possible!

Thanks so much man,
Phil

[brucek]

Just click and save and then remove the bogus .mdat extension that I used to bypass the .cal file site restrictions. (i.e. rename it to AudioAdvantageSRM.cal)

AudioAdvantageSRM.cal.mdat

brucek

[brucek]

I'm assuming that it will be easy to load by browsing my saved location...

Yep..........

I did clear the calibration file and I think the level is at 75db (how do I check?).

Just go through the standard setup routine.
Check Levels routine, and then Calibrate SPL level routine (to 75dB) and then Measure from 0-~15K..........
