Thanks for that John..........yeah i'm using a s/b live24 s/c laptop xp and i'm also using the ecm8000 measurement mic and a B mic800 preamp......would it be easier to use the spl meter in place of the B/mic although the mic being more accurate.

I've selected the s/b live24 s/c in the input devices and the same in output devices is this correct....My connect setup is as follows (sub only) sub is going into bfd and instead of being connected to my receiver its connected to the line out on the s/c (front speaker Chanel) via a 3.5mm to twin phono adapter.
Then the mic is connected to the preamp which is connected to the line in with said same adapter both as stated in rew......on the preamp there is only 1 jack plug output which i have connected one side of a 2 way (2 phone's and 2 jack plug connectors) red/black into the line in is this alright/ok.

Has the fact that i've kept the loopback on my major down fall which i only did because i thought thats so i could check the device box's and rew would automatically control all the volumes.....but it seems that was a wrong move.

I appoligise if all this does not make complete sense.
