Carma problems


Active Member
Hi All,

I have been using Carma to try and sort out my speaker and sub setup. first a question, in carma, should I be using the sub(DTS) or the sub(pcm) in the carma modes to calibrate my subwoofer?

I have been using the sub(dts) one. It shows I have a massive dip around 50hz. My sub amp has a 5 channel PEQ, so I thought I could just put the eq values that I use in Carma into the sub amp peq. I try to smooth out most of the lare dips and spikes etc. My problem is, when I put these values into my sub amp and do a measurement in Carma I get the orginal curve back again.

Does this mean that my Subamp is not doing any EQ? I tried it with Audessy on and off in my receiver.

Thanks for any help.

the same happens if I use the sub(pcm) surely I should be getting a different curve everytime I make changes to the EQ? It's not happening here, which leads me to believe that the XTZ Sub Amp is not doing anything.

edit:- Actually, the XTZ PEQ is doing something. I can store different profiles. When I switch from a default profile to one I created using Carma, the difference is amazing. The sound is so much better,

but yet if I measure both profiles in carma, I get the same curve!! Does Carma somehow take out all the EQ measurements? It's really wierd and makes no sense.

Do any of your sub settings or switches turn the PEQ off ?

What sub do you have ?

My Sub is an XTZ W12.18 passive, connected to an XTZ DSP Sub AMP. I haven't seen anyway of turning off the PEQ. Maybe there is I might contact XTZ tomorrow and ask.
