My older posts dealt with too low levels for inputs in audacity...

Again: your levels then were perfect.

I

got a better RIAA preamp with higher output, and all seemed OK...
except
that I now have a vinyl record that gives too high output, and I have
problem recording/digitizing it.

You then have to reduce the signal level before the signal enters the
soundcard. Otherwise the sound card will clip. A simple 10 dB attenuator
will do, say 10 kOhm in series and 5 kOhm to ground in a small plastic box.

I can't monitor the analog signal input using Audacity. The input
comes from a Cambridge Audio 640 P RIAA preamp, which is fed from a
vinyl turntable Thorens TD 90. The preamp does not have an output
setting knob.

With grammophone cartridges having their output signals within a 10 dB
window it seems like folly to me not to have an output level adjustment
option, a -5 and -10 dB switch would have been wise design from the
manufacturer ...

Thanks in advance for helping me with envy24control settings.

Forget everything about adjusting the record level after digitizing, it
needs to be adjusted before enters the sound card or the sound card will
clip. Welcome to the simplicity of line level contraptions. Your problem is
partly that the AP2496 is adapted to home audio line levels and partly that
Cambrigde appear to have put extra gain in that RIAA to match the +8 dB
(ref. 0.775 volt) output from a CD-player.

If you need to vent your frustration, then write to Cambridge Audio and ask
them how come they forgot a -5 and -10 dB option on the output of the RIAA
box. It is well warranted to have that since cartridges for 47 kOhm loading
have their out spread within approximately 12 dB.

Kind regards
