Yeah I guessed so - but then this forum is about wishing for the moon, anyway...

The FA screens look as if they might be logarithmic, based on the frequency sweeps I'm using.

I'm not wholly sure (being thick) what you mean regarding your last statement - do you mean that the output shown is not modified by the EQ? This is what I would expect, ie. it's "pre-EQ" and represents the idealised spectrum output by the decoder. It is not (I guess) showing the actual post-EQ modified sound levels - is this correct?

I am only really interested in it as an indicator of spectral content - I really need a spectrum analyser with a microphone in the car if I am serious about using the Equaliser to set up my amp, but that's rather difficult to obtain (unless you know how to set up a storage scope to do this? What about a high impedance mike at head height and a slow (20-30s sweep time) on the scope? Hmmm.... good idea )
