Thanks Tim. How very helpful people here are!

Funnily enough, putting this question on the forum spurred me on to actually get some answers myself, so I trotted off to the Sifam Website where I discovered the two ranges (sold at RS): the cheaper "Presenter" range which include the AL29 and AL39 don't conform to the VU standard while only the R32AF in the "Clarity Focus" range, priced around £60 upwards conforms to the VU standard.

Apparently, there's a book called "Handbook for Sound Engineers - The New Audio Cyclopaedia" which includes various circuits for VU meter buffer amplifiers and the such. They have it at my local library so I'm going to borrow it for a few weeks.

But Tim, here's another question. Can you explain to me exactly what the buffer amplifier does?

Thanks, Will
