Preparing a mix for vinyl mastering

[The_G]

I'm going to be on a compilation, which will be mastered by the guys who are cutting the record. Just want to double check what I need to do to make sure the mix is ready for vinyl:

1. Mono bass under 200hz
2. Attenuate high frequencies
3. Leave -6db peak headroom

Are those all correct and is there anything I'm leaving out?

[Mattias]

Just make sure there are no major sibilance (as one always should do). Don't bother with mono under a certain frequency range, the guy mastering the record will take all necessary actions needed to make the transfer.

Keep the mix how you want it, don't think ahead of what you "might need" to do.

A balanced mix with no clipping and harsh top end and you're golden as always!

Yeah don't worry about anything you listed really.
If you made the tune with the bass in mono then cool, but you don't need to go do it to the master if you forgot.
Leave the high end, accell limiting may get applied by the cutter if necessary.
Even -6db peak is is not necessary really.
Just make sure you have enough headroom to avoid clipping. And avoid heavy master buss compression.

High end distortion can be problematic at 5k and above, so be aware of that when making music with distortion.

Other than that, just leave it to the engineer.

You can submit mixes which peak less than -6 dB without a problem. Keep the mix bus clean, unless you have chosen to color the master with a conscious effect/color such as distortion (like the currently trendy lo-fi house sound). I attenuate over-resonating or muddy frequencies using a parametric EQ on rare occasions. I find that even the best mastering engineers are very selective with attenuation unless they re-balance a mix (suggesting that the original mix down wasn't very good).

Just trust your ear and gut. If you're happy with what you hear then don't expect a huge surprise, but a more "refined" version coming back.
