Pioneer no longer documents what it does. That was another point in me thinking it was no longer done, because before it was explicitly spelled out what would happen.

My Sony's manual even went as far as to talk about the +10 dB needed to be applied to the LFE signal to mix it at the right level with the mains, but mentioned it could cause distortion. The LFE mix level would be set from -10 to +10 dB (with separate settings for Dolby and DTS).
