Digital application of RIAA curve?

Well Bob, better give in now, eh? Somebody going to turn the lights out? Goodnight all...

Only joking but seeing it gets a free plug twice above I just thought I'd mention something about PGA's or programmable gain amplifiers but I also have to abide by the rules of this forum so I'd best not say exactly what I was going to say...

But I would say we used plenty on DC operated broadcast desks and I won't use them, period.

As an old maths mentor Dr Jones used to start off with: "from what we know..."

So what do we know?

(clue: http://www.phonostagepreamp.com/all-about-the-phono-preamp.htm tab3

"Infinite boost from a virtually zero frequency, say 1Hz to 100kHz, to ensure the entire audio band is reproduced perfectly flat, would require a dynamic range of 100dB just for that purpose.

That doesn't take into consideration some 60dB (at least) signal to noise, or the 14dB of headroom a recording requires — in total 174dB of dynamic range which is beyond what physics allows even to this day."

So what do we know already about the aforementioned product?

It must have some basic, probably RIAA equalisation, built into the analogue stage, about which "turns" the software EQ, or...  it does it all flat within a much restricted dynamic range.

Thank you Dr Jones for equipping me with x-ray eyes!

Every education facility should have a Dr Jones!
