Just like Ethan, I didn't have much luck with ETF's mixer...I'd strongly suggest using the standard Windows mixer.
I agree. I just couldn't seem to get it working. After a lot of messing about, I find that using WAVE volume control, I can adjust the 'Level check' dB figures to between -10 and 0 as per the 'manual'. I'm guessing that WAVE is internally generated, because even when I pull the cable loop out completely, it still seems to work.
That aside, the graphed response (refer to attachment) seems to be very good (I think). At least, it matches what the 'manual' says it should, so I think I can assume that everything is ok....
By the way, how do you attach 'thumbnails' as opposed to 'attachments'?
EDIT: Doh!!!

The attached pic (hopefully) shows that you connect L out to L in (via a double female connector), R in goes to the SPL meter, and R out goes to your amp. On Ethan's advice, I use a splitter at the amp to ensure I get the same sound from both speakers (it does work much better).
1. Is the attached photo 'adapter' what you mean by 'double female connector'?
2. If the answer to 1 above is yes, then can you confirm that I have interpreted things correctly?;
I'll plug the 1/4" into the computer's headphones jack and the L/R RCA end of that cable will plug into both jacks of one side of the adaptor. From the other side, the Left can be connected with a single cable to my computer's Left-in jack, and the RS SPL meter will be connected, again by a solitary cable, to my computer's Right-in jack. This would only leave the connection to be made, via the remaining Right from the adaptor to the amp.
This is where I'm a little confused. If I'm taking a mono signal (the Right) to the amp, why am I splitting it into two mono signals to put through the amp's stereo inputs? I know you wrote:

...but why do I want the same sound from both speakers? I'll want to record the frequency response from the L/R speakers independantly won't I? And assuming that I do need to do as Ethan and yourself advise, how do I split the Right cable's signal into two? What kind of adapter? Do you have any pictures?

Yeah, I suspected it would have to be 'fast'; the frequency sweep would never be recorded accurately if set to 'slow'.

p.s. I'm getting there! Slowly but surely! Thanks for all your help so far everyone.
