Prob did all kind off things wrong but i hope you can help me this was the reading of the sub. Next question i have if you meassure the sub you connect only the sub or all the other speakers too??

Just allready thnx for looking, and helping

Next question i have if you meassure the sub you connect only the sub or all the other speakers too??

Just disconnect the speakers and do the sub only when setting up the BFD. Once the sub is equalized, then add the mains to check the interaction around the crossover area. Tweak to fix this if there's a problem. Always have the receiver in stereo mode with crossovers enabled.

Prob did all kind off things wrong

Please post your graphs for the sub with a horizontal axis of 15Hz to 200Hz. Your vertical axis is correct.

See how your response is basically a mirror image of the microphone calibration file? You have a soundcard internal loopback monitor enabled. Turn it off.

Internal Loopback of the soundcard how do i turn this off?

[brucek]

Somewhere in the Creative Audio Mixer application will be an enable monitor or "what you see is what you get" selection..

Hi Marco,

The problem is you have selected "What U Hear" as the input, this is just an internal soundcard loopback used for monitoring the output. You need to select the Line in, also make sure CMSS and any other effects are turned off.

[Gizmo]

Hi Both,

Thnx for the help , tommorow i will check it and try again. And post some new pics. I put it on what you hear because with line in there was no reaction, but i forgot to put off cmss, i hope that was the prob.

Regards,
Marco

[JohnM]

CMSS will not have been the reason for no signal from Line In, would more likely be something wrongly set in the Creative Mixer or with the external connections. Best post a screenshot of the Creative Mixer after REW has started up so we can see whether it looks right.

Hi tried to get going on with line in, but i didn't get that working ,

So i tried again with callibrating twice.


But still no good, all ready thnx for helping.

You have the same mirror curves as I did until brucek put me right.

You must use Line In and try to set your soundcard to the illustrations in the help files.

The help files are above the BFD-REW forum threads.

Click on the Creative volume/mixer symbol on the bottom of your screen.

Select mixer then check that you have Line in set and not What you hear.

In my Creative mixer pop-up screen the Line in setting is on the right.

What you hear is printed on its side and difficult to spot unless you know what you are looking for.

[JohnM]

The Creative Mixer shot in the pdf looks like it only has the replay sources, there should be a similar panel for the input sources? Another possibility is that on some creative mixers you have to unmute line in on the replay panel, so both wave and line in are not muted, worth trying that. Also worth using the option in the REW Soundcard menu to generate a debug file and attach that.

[JohnM]

Final question for tonight, what kind of cable are you using to connect the line in to the front out?

[Gizmo]

Thnx for the advice, i'm gonna check this afternoon if there is a mute button somewere. I'm using a speaker cable what i used for the sub. With red / wite.

My German is no good, but I think
instellingen2.pdf shows Line-In muted..

[Gizmo]

Hi all and thnx for so far,

I found the problem , and that was that i let the record button at left channel but i needed put it at right channel.
So finaly, it worked here is the picture.

It look like the sub is drunk .



So now i should messure every speaker alone or all together?

I did the automatic measurement.

Can you explain this further. I don't really understand. Let me post a few picture to see if we're on the same page.

The line-in and line out of the soundcard are stereo, and as such require a stereo connector to work properly. You will only be using one channel of the stereo connector, but it still must be a stereo adapter.

I presume you are using the line-in and line-out ports I show in the picture below with red arrows.

Below that is a picture showing the correct use of a stereo adapter to connect the line-in and line-out of the soundcard.

Is this the situation you are using (or similar)?

Hi Bruce,

Thnx for reply we were probely typing at the same time. But the setup was oke only i had the wrong record button in the program. The button next to DB SPL was set on the left channel but had to be the Right one.

What do you think of the sub its a sub from kef 2001 series

[brucek]

When testing the response of a subwoofer you want to disconnect all other speakers and test the sub by itself with the receivers crossover set to the frequency you normally use (i.e. 80Hz).

I don't see any 2001 series subwoofers on KEF's rather horrible site, but I do see that they have a 2005.2 series with a frequency bottom of 30Hz. I am assuming your sub is in this range?

Either way, it isn't extending very low and I guess you're not getting much low bass in the sound. You're really listening to what's called one-note bass that is around 65Hz. Not too good.

You need to test the sub alone and try and place it in a corner of the room that produces the best low end extension. REW makes the testing fairly easy. You can move the sub around or alternately place the sub in your listening position and move the microphone around to the corners to find the best spot.

It's the same set of Keff 2005.2. Oke i'm gonna move the bub around. I really like the program only i'm just looking around the corner concernig music and sound. So far thnx allready

[Gizmo]

I've moved the sub to the corner see picture



and here is a screen pic,

sub verplaatst.pdf

Mine setup is as folowed,

got a receiver from Sony strd 940, and the KEF 2005,2 (2001) speakers.

A one base sub means its not the best around the block??

Next week i recieve the usb with midi cables so i can adjust the settings of the bfd, any tips for so far??

[brucek]

I don't really understand why your response is dropping off so quickly at 60Hz. It should extend much lower.

Is this a response of the sub only that you've posted?

How large is your room.

brucek

[Gizmo]

the room aint that big i think about 5 by 6/7, humm i changed in the settings the hz from 200 hz to 90hz for the speakers, tommorow i will look if this looks better.

[brucek]

Next week i recieve the usb with midi cables so i can adjust the settings of the bfd

Note that this feature does not work in the BFD...

Actually, I've read that it works on BFDs older than 2006 (prior to version 1.3)
and Behringer has offered beta 1.4 EPROM fix.
( Sorry, I'm net yet allowed to post URLs )

Meanwhile, I thought that the Extigy has built-in MIDI?

Yep..

Now you can.

The problem is with the BFD, not REW.....

[Gizmo]

Oh oke, how can i see that the midi works or not??
