Sony PS-J10 internal RIAA normalizer, use the internal one, or should I build my own?

I have a Sony PS-J10 turntable with internal RIAA curve normalizer. When that normalizer is on, I can connect the record player to a standard line input and it will sound - well normalized.

The problem is though, it seems it's pretty heavy on the trebles, so I use the equalizer on my mixer to tweak that. Now, would it make sense, to build my own RIAA normalizer / phono pre-amp? Or would I most probaly not gain anything and maybe I actually should stick with the internal one?

Any suggestions?

Mmm... the RIAA curve precisely reduces the highs and boosts the lows. Do you mean that the curve reduces the highs too much? Maybe that's how the LP is recorded.

About making your own preamp, i wouldn't go that route. First locate another mixer table or integrated amplifier that has phono input and doublecheck if it is really that different from what you get with the setting on.

Edit: Found the manual. It doesn't say much about the EQ it does (why would it be different than RIAA?):


"Connect the red plug into the right-channel phono in jack ® and the white plug to the left channel phono-in jack (L) on the amplifier.
If your amplifier does not have phono in jacks, connect the plugs to the aux in o line in jacks.

Set EQ on/off on the bottom panel according to the amplifier connetion as follows:
For connection to Set EQ
-------------------- -------
phono in jacks off
aux/line in jacks on"
